Reproductive System --Structure & Function
Inflammatory disease of the vulva.
Vulvitis
Herpes simplex virus _____is responsible for greater than 90% of recurrent genital herpes infections.
Type 2
Fibrocystic changes in the breast are not uncommon. How is the diagnosis of fibrocystic changes made?
Ultrasonography and mammography Rationale: Diagnosis of fibrocystic changes is made by physical examination, mammography, ultrasonography, and biopsy (i.e., as- piration or tissue sample). Patient history and galactography are not used to diagnose fibrocystic changes in the breast.
Ectopic pregnancies are true gynecologic emergencies and are considered the leading cause of maternal death in the first trimester.What diagnostic test would you expect to have ordered for a suspected ectopic pregnancy?
Ultrasonography followed by serial hCG tests. Rationale: Diagnostic tests for ectopic pregnancy include a urine pregnancy test, ultrasonography, and B-human chorionic gonadotropin (hCG), the hormone produced by placental cells) levels. Serial - hCG tests may detect lower-than-normal hCG production. Transvaginal ultrasound studies after 5 weeks' gestation may demonstrate an empty uterine cavity or presence of the gestational sac outside the uterus. In a comparison of various protocols for diagnosing ectopic pregnancy, ultrasound followed by serial hCG levels was found to yield the best re- sults.
Primary ______is the failure to menstruate by 15 years of age or by 13 years of age if failure to menstruate is accompanied by absence of secondary sex characteristics.
Amenorrhea
3. What are the side effects of excess synthetic androgens?
Among the undesired or harmful effects of supraphysiologic doses of androgens are acne, decreased testicular size, and azoospermia. These effects may persist for months after use of the agents has ceased. Because testosterone can be aromatized to estradiol in the periph- eral tissues, androgens can also produce gynecomastia.
The male reproductive system undergoes changes as aging occurs. What is the term used to describe a relative or absolute hypogonadism associated with aging?
Andropause
The term____ has been used to describe an ill-defined collection of symptoms in aging men, typically those older than 50 years, who have a relative or absolute hypogonadism associated with aging.
Andropause
Leiomyomas, or intrauterine fibroids, are the most common form of pelvic tumor. Approximately half the time leiomyomas are asymptomatic. What are the symptoms of leiomyomas that are not asymptomatic?
Anemia and urinary frequency. Rationale: Leiomyomas are asymptomatic approximately half of the time and may be discovered during a routine pelvic examina- tion, or they may cause menorrhagia (excessive menstrual bleeding), anemia, urinary frequency, rectal pressure/constipation, abdominal distention, and, infrequently, pain. Diarrhea and urinary retention are not symptoms of leiomyomas.
Observational studies indicate a possible preventative role of estrogen in the development of Alzheimer disease through ___ mechanisms to prevent vascular injury, increased cerebral blood flow, and altered brain activation.
Anti- inflammatory
Cancer of the breast is the most common cancer in women. Many breast cancers are found by women themselves while doing breast self examination. When should postmenopausal women perform breast self-examination?
Any day of the month. Rationale: Postmenopausal women and women who have had a hysterectomy can perform the examination any day of the month.

Herniation of the bladder into the vagina .
Cystocele
5. The mother of a 5-year-old boy brings him into the clinic because of a firm swelling around one of his testes. What diagnosis is suggested?
Hydrocele. *Rationale:* Hydroceles are palpated as cystic masses that may attain massive proportions. With sufficient fluid, the mass may be mistaken for a solid tumor. Transillumination of the scrotum (i.e., shining a light through the scrotum to visualize its internal structures) or ultra-sonography can help to determine whether the mass is solid or cystic and whether the testicle is normal.
Scanty menstruation
Hypo-menorrhea

Epispadias.
Persistent inability to achieve and maintain an erection
Erectile dysfunction
____is commonly classified as psychogenic, organic, or mixed psychogenic and organic.
Erectile dysfunction
4. How does the penis become erect?
Erection involves the shunting of blood into the corpus cavernosum. It is controlled by the sympathetic, parasympathetic, and nonadren- ergic-noncholinergic systems. Nitric oxide is the released locally as a mediator that produces relaxation of vascular smooth muscle. In the flaccid state, sympathetic discharge through -adrenergic receptors maintains contraction of the arteries that supply the penis and vascular sinuses of the corpora cavernosa and corpus spongiosum. Parasympathetic stimulation produces erection by inhibiting sympathetic neurons that cause detumescence and by stimulating the release of nitric oxide to effect a rapid relaxation of the smooth muscle in the sinusoidal spaces of the corpus cavernosum.
Chancroid or soft chancre is a highly contagious STI usually found in the Southeast Asian and North African populations. What is the recommended treatment for chancroid?
Erythromycin. Rationale: Chancroid organisms have shown resistance to treatment with sulfamethoxazole alone and to tetracycline. The Centers for Disease Control and Prevention (CDC) recommends treatment with azithromycin, erythromycin, or ceftriaxone.
____ stimulates increased vascularity of the breasts and the growth and extension of the ductile structures, causing "heaviness" of the breasts.
Estrogen
The ovaries have a dual function: they store the female germ cells, or ova, and produce the female sex hormones,____and_____ .
Estrogen, Progesterone
There are two types of vulvar cancer. One type is found in older women, and one type is found in younger women, generally younger than 40 years of age. The type found in younger women thought to be caused by which of the following?
Human papillomavirus (HPV). Rationale: One-third to one-half of vulvar intraepithelial neoplasm (VIN) cases appear to be caused by the cancer-promoting potential of certain strains (subtypes 16 and 18) of HPV that are sexually transmitted and are associated with the type of vulvar cancer found in younger women. The other answers are not thought to be associated with vulvar cancer in younger women.

...
THE MALE REPRODUCTIVE SYSTEM
...
What are the three most prominent theories of the pathogenesis of endometriosis?
4. The first theory, the regurgitation/implantation theory suggests that menstrual blood con- taining fragments of endometrium is forced upward through the fallopian tubes into the peritoneal cavity. Retrograde menstruation is not an uncommon phenomenon, and it is unknown why endometrial cells implant and grow in some women but not in others. A second theory, the metaplastic theory, proposes that dormant, immature cellular elements, spread over a wide area during embryonic development, persist into adult life and then differentiate into endometrial tissue. A third theory, the vascular/lymphatic theory, suggests that the endometrial tissue may metastasize through the lymphatics or vascular system. Genetic and immune factors also have been studied as contributing factors to the development of endometriosis.
Couples who are being treated for infertility often choose to try in vitro fertilization (IVF). When using this technique, the eggs are inseminated with sperm in a culture dish. After a period of time, the ova are evaluated for signs of fertilization. If signs of fertilization are present, when are the fertilized eggs placed in the woman's uterus?
48 to 72 hours after egg retrieval. Rationale: Between 12 and 24 hours after insemination, the ova are evaluated for signs of fertilization. If signs are present, the ova are returned to the incubator, and 48 to 72 hours after egg retrieval, the fertilized eggs are placed into the woman's uterus by means of a transcervical catheter.
1 . After inoculation with human papilloma virus (HPV), genital warts may begin to grow.They usually manifest as soft, raised fleshy lesions on the external genitalia of either a male or female patient. What is the incubation period for HPV induced genital warts?
6 weeks to 8 months. * Rationale:* The incubation period for HPV- induced genital warts ranges from 6 weeks to 8 months, with a mean of 2 to 3 months.
The penis
A cylindrical organ consisting of three longitudinal compartments.
The Vagina
A fibromuscular canal that receives the penis during sexual intercourse and is the exit route for menstrual fluids and products of conception. The vagina leads from the introitus (its external opening) to the cervical portion of the uterus.
Uterine prolapse is a disorder of pelvic support and uterine position. It can range in severity from a slight descent of the uterus into the vagina, all the way to the entire uterus protruding through the vaginal opening. In women who want to have children or in older women who are at significant risk if surgery is performed, what device is inserted to hold the uterus in place?
A pessary. pessary can be inserted to hold the uterus in place and it may stave off surgical intervention in women who want to have children or in older women for whom the surgery may pose a significant health risk.
What is the only approved vaccine for cervical cancer and how does it work?
A quadrivalent vaccine (Gardisil) to prevent infection with the HPV subtypes 6, 11, 16, and 18 was licensed by the US Food and Drug Ad- ministration (FDA) in June 2006. The vaccine targets the two strains of HPV (HPV 16 and18), which are responsible for 70% of cervical cancer, and the two most common benign strains (HPV 6 and 11), which account for up to 90% of genital warts. The vaccine is targeted for females between the ages of 9 to 26 years, optimally before initiating sexual activity. Clinical studies provided to the FDA have confirmed that the vaccine appears safe and effective in inducing long-term immunity to HPV.
The manifestations of____include fever and chills, malaise, myalgia, arthralgia,frequent and urgent urination, dysuria, and urethral discharge.
Acute bacterial prostatitis
____is the condition in which en- dometrial glands and stroma are found within the myometrium, interspersed between the smooth muscle fibers.
Adenomyosis
The causes of infertility can be in either the male or the female. Male tests for infertility require a specimen of ejaculate that is collected when?
After 3 days of abstinence. Rationale: The specimen is best collected by masturbation into a sterile container after 3 days of abstinence.
Mastitis is an inflammation of the breast that can occur at any time. What is the treatment for mastitis?
Application of heat or cold. Rationale: Treatment for mastitis symptoms include application of heat or cold, excision, aspiration, mild analgesics, antibiotics, and asupportive brassiere or breast binder.
What is the genetic component of breast cancer?
Approximately 5% to 10% of all breast cancers are hereditary, with genetic mutations causing up to 80% of breast cancers in women under age 50. Two breast cancer susceptibility genes—BRCA1 on chromosome 17 and BRCA2 on chromosome 13—may account for most inherited forms of breast cancer. BRCA1 is known to be involved in tumor suppression. A woman with known mutations in BRCA1 has a lifetime risk of 60% to 85% for breast cancer and an increased risk of ovarian cancer. BRCA2 is another susceptibility gene that carries an elevated cancer risk similar to that with BRCA1.
Androgens
Are primarily male sex hormones but in women contribute to the pre pubertal growth spurt, pubic and axillary hair growth, and activation of sebaceous glands.
1 . What are the endocrine changes that occur to stimulate male puberty? 237
At approximately 10 or 11 years of age, the adenohypophysis, or anterior pituitary, under the control of the hypothalamus begins to secrete the gonadotropins that stimulate testicu- lar function and cause the interstitial cells of Leydig to begin producing testosterone. Approximately the same time, hormonal stimulation induces mitotic activity of the germ cells that develop in sperm. After cell maturation has begun, the testes begin to enlarge rapidly as the individual tubules grow. Full maturity and spermatogenesis usually are attained by 15 or 16 years of age.
Inflammation of the vagina that occurs after menopause
Atropic vaginitis

Cardiovascular, metabolic
An 18-year-old woman presents at the clinic complaining new onset breakthrough bleeding, even though she is on contraceptives. What contraceptive use, along with new-onset breakthrough bleeding, has been associ- ated with pelvic inflammatory disease.
Depo-Provera. New-onset breakthrough bleeding in women who are on oral contraceptives or medroxyprogesterone contraceptive injection (Depo-Provera) has been associated with pelvic inflammatory disease (PID). The other forms of contraception have not been associ- ated with PID.
What is the normal method of detecting/diagnosis cervical cancer?
Diagnosis of cervical cancer requires pathologic confirmation. Papanicolaou smear results demonstrating squamous intraepithelial lesion (SIL) often require further evaluation by colposcopy during which a biopsy sample may be obtained from suspect areas and examined microscopically. An alternate diagnostic tool in areas where colposcopy is not readily available is a noninvasive photographic technique, in which a cervicography camera is used to pho-tograph the cervix. The projected cervicogram (a slide made from the film) is then sent for expert evaluation. In one study, the cer- vicogram was found to give a greater yield of cervical intraepithelial neoplasia (CIN) than Papanicolaou smear alone in patients with previous abnormal Papanicolaou smears.
Ovarian cancer, once thought to be asymptomatic, has now been shown to produce nonspecific symptoms, which makes the diagnosis of ovarian cancer difficult. What symptoms are believed to have a strong association to ovarian cancer?
Difficulty eating, Bloating Abdominal or pelvic pain : Symptoms believed to have a strong correlation with ovarian cancer include abdominal or pelvic pain, increased abdominal size or bloating, and difficulty eating or feeling full quickly after ingesting food. Increased intestinal gas and an increased appetite are not highly correlated with ovarian cancer.
_____and _____, which con- sists of dilating the cervix and scraping the uterine cavity, is the definitive procedure for diagnosis of endometrial cancer because it provides a more thorough evaluation.
Dilation , curettage
Excess of lactobacilli
Doderlein cytolysis
Large mononuclear cells filled with intracytoplasmic gram-negative rods.
Donovan bodies
How does lactation occur?
During lactation, milk is secreted by alveolar cells, which are under the influence of the anterior pituitary hormone prolactin. Milk ejection from the ductile system occurs in response to the release of oxytocin from the posterior pituitary. The suckling of the infant provides the stimulus for milk ejection. Suckling produces feedback to the hypothalamus, stimulating the release of oxytocin from the posterior pituitary. Oxytocin causes contraction of the myoepithelial cells lining the alveoli and ejection of milk into the ductal system.
What can cause erectile dysfunction?
Dysfunction of pudendal nerves
Describe the alterations in a normal period and name the hormone thought to be responsible.
Dysfunctional menstrual cycles are related to alterations in the hormones that support normal cyclic endometrial changes. Estrogen deprivation causes retrogression of a previously built-up endometrium and bleeding. Such bleeding often is irregular in amount and duration, with the flow varying with the time and degree of estrogen stimulation and with the degree of estrogen withdrawal. A lack of progesterone can cause abnormal menstrual bleeding; in its absence, estrogen induces development of a much thicker endometrial layer with a richer blood supply. The absence of progesterone results from the failure of any of the developing ovarian follicles to mature to the point of ovulation, with the subsequent formation of the corpus luteum and production and secretion of progesterone.
Pain accompanying the contractions associated with menses
Dysmenorrhea
Painful intercourse
Dyspareunia
4.Cryptorchidism, left untreated, is a high risk for testicular cancer and infertility. What are the treatment goals for boys with cryptorchidism?
Easier cancer detection.*Rationale:* The treatment goals for the boys with cryptorchidism include measures to enhance future fertility potential, placement of the gonad in a favorable place for cancer detection, and improved cosmetic appearance.
_____occurs when a fertilized ovum implants outside the uterine cavity, the most common site being the fallopian tube.
Ectopic pregnancy
Expulsion of the sperm from the urethra
Ejaculation
Sperm move from the epididymis to the urethra
Emission
4. What is the normal role of estrogen in female development?
Estrogens are necessary for normal female physical maturation. In concert with other hormones, estrogens provide for the reproductive processes of ovulation, implantation of the products of conception, pregnancy, parturition, and lactation by stimulating the development and maintaining the growth of the accessory organs. In the absence of androgens, estrogens stimulate the intrauterine development of the vagina, uterus, and uterine tubes from the embryonic müllerian system. They also stimulate the stromal development and ductal growth of the breasts at puberty. Estrogens are responsible for the accelerated puber- tal skeletal growth phase and for closure of the epiphyses of the long bones; they contributeto the growth of axillary and pubic hair, and alter the distribution of body fat to produce the typical female body contours, including the accumulation of body fat around the hips and breasts. Larger quantities of estrogen stimulate pigmentation of the skin in the nipple, areolar, and genital regions.
3. What is the cardioprotective effect of estrogen?
Estrogens have additional cardioprotective actions, including direct antiatherosclerotic effects on the arterial wall (augmentation of vasodilating and antiplatelet aggregation factors such as nitric oxide and prostacyclin), vasodilation through endothelium-independent mechanisms, antioxidant activity, reduced levels of angiotensin converting enzyme and renin, reduction of homocysteine levels, improved peripheral glucose metabolism with subsequent decreased circulating insulin lev- els, and direct effects on cardiac function.
2. What relationship is there between body composition and a normal menstrual cycle?
Evidence indicates that a certain minimal body weight (48 kg) and fat content (16%-24%) are necessary for menarche to occur and for the menstrual cycle to be maintained. This is supported by the observation of amenorrhea in women with anorexia nervosa, chronic disease, and malnutrition and in those who are long-distance runners. In women with anorexia nervosa, gonadotropin and estradiol secretion, including LH release and responsiveness to the hypothalamic gonadotropin-releasing hormone (GnRH), can revert to prepubertal levels.
The two fallopian tubes
Extends from the uterus to the ovaries. Their function is to conduct ova from the spaces around the ovaries to the uterus. fertilization normally occurs in the fallopian tubes.
Genital warts typically present as soft, raised, fleshy lesions on the ______, including the penis, vulva, scrotum, perineum, and perianal skin.
External genitalia
The cause of noninflammatory prostatitis is unknown, but because of the absence of inflammation, the search for the cause of symptoms has been directed toward______sources.
Extraprostatic
Growth, prepubertal maturation, the reproductive cycle, and sex hormone secretion are regulated by___and___from the anterior pituitary gland.
FSH, LH
The end of the____nearest the ovary forms a funnel-like opening with fringed, finger-like projections, called fimbriae, which pick up the ovum after its release into the peritoneal cavity after ovulation.
Fallopian tube
Untreated chlamydial infection results in _____ damage in female patients.
Fallopian tube
There is no known cure for genital herpes and methods of treatment are often symptomatic. Pharmacologic treatment of genital herpes includes which drugs?
Famciclovir. *Rationale:* The antiviral drugs acyclovir, valacyclovir, and famciclovir have become the cornerstone for the treatment of genital herpes.
Androgens can be converted to estrogens peripherally, especially in____.
Fat tissue
The absence of ______ of cervical mucus can indicate inadequate estrogen stimulation of the endocervical glands or inhibition of the endocervical glands by increased secretion of progesterone.

Unlike the female egg, which remains briefly fertile, spermatozoa can remain fertile for up to 42 days. Where are the spermatozoa stored so they maintain their fertility?
Genital ducts
_____is one of the most common causes of genital ulcers in patients in the United States.
Genital herpes
______are caused by the human papillomavirus (HPV).

Bacterial vaginosis is the most common vaginal infection seen by health care providers. What is the predominant symptom of bacterial vaginosis?
Grayish white discharge with a fishy odor. *Rationale:* The predominant symptom of bacterial vaginosis is a thin, grayish-white discharge that has a foul, fishy odor.
Tertiary syphilis is a delayed response of untreated primary syphilis that can occur as long as 20 years after the primary disease. When tertiary syphilis progresses to a symptomatic stage, it can produce localized necrotic lesions. What are these lesions called?
Gummas. *Rationale:* The syphilitic gumma is a peculiar, rubbery, necrotic lesion that is caused by noninflammatory tissue necrosis. Gummas can occur singly or multiply and vary in size from microscopic lesions to large, tumorous masses. They most commonly are found in the liver, testes, and bone. Chancres occur in primary syphilis. Chancroid is a sexually transmitted infection (STI).
Trichomoniasis is an STI that can occur in either sex. Men carry the protozoan in the ure- thra and prostate and remain asymptomatic. This anerobic protozoan can cause a number of complications. What is a risk factor for trichomoniasis in both men and women?
HIV. *Rationale:* Trichomoniasis can cause a number of complications. It is a risk factor for HIV transmission and infectivity in both men and women. In women, it increases the risk tubal infertility and atypical pelvic inflammatory disease, and it is associated with adverse outcomes, such as premature birth, in preg- nant women.
A preponderance of evidence suggests a causal link between _____infection and cervical cancer.
HPV
. Diseases of the external genitalia are similar to those that affect ______skin else-where in the body.
Hair bearing
2. How do herpes simplex virus (HSV)-1 and HSV- 2 spread, and where do they reside in the body?
Herpes simplex virus (HSV) is transmitted by contact with infectious lesions or secretions. Herpes simplex virus type-1 is transmitted by oral secretions, and infections frequently occur in childhood. Herpes simplex virus type-1 can be spread to the genital area by autoinoculation after poor handwashing or through oral-genital contact. Herpes simplex virus type-2 usually is transmitted by sexual contact but can be passed to an infant during childbirth if the virus is actively being shed from the genital tract. In genital herpes, the virus ascends through the peripheral nerves to the sacral dorsal root ganglia. The virus can remain dormant in the dorsal root ganglia, or it can reactivate, in which case the viral particles are transported back down the nerve root to the skin, where they multiply and cause a lesion to develop.
In primary dysmenorrheal when contraception is not desired, what is the treatment of choice?
Ibuprofen : Although analgesic agents, such as aspirin and acetaminophen, may relieve minor uterine cramping or low back pain, prostaglandin synthetase inhibitors (e.g., ibuprofen, naproxen, mefenamic acid, in- domethacin) are more specific for dysmenorrhea and the treatment of choice, if contraception is not desired.
Differentiation of female & male genitalia begins
In the 8th week of embryonic development, when the gonads of genetically male embryos begin to secrete male sex hormones, primarily testosterone. Until that time, the primitive reproductive organs of males and females are homologous ( the same).
2. Describe the process of spermatogenesis.
In the first stage of spermatogenesis, small and unspecialized diploid germinal cells located immediately adjacent to the tubular wall, called the spermatogonia, undergo rapid mitotic division and provide a continuous source of new germinal cells. As these cells multiply, the more mature spermatogonia divide into two daughter cells, which grow and become the primary spermatocytes—the precursors of sperm. Over several weeks, large primary spermatocytes divide by a process called meiosis to form two smaller secondary spermatocytes. The spermatid elongates into a spermatozoon, or mature sperm cell, with a head and tail.
_________is the inability to conceive a child after 1 year of unprotected intercourse.
Infertility
Primary genital herpes is a sexually transmitted infection (STI) caused by either the herpes simplex virus type 1 (HSV-1) or the herpes simplex virus type 2 (HSV-2). What are the initial symptoms of primary genital herpes infections?
Itching; Genital pain; Small pustules. *Rationale:* The initial symptoms of primary genital herpes infections include tingling, itching, and pain in the genital area, followed by eruption of small pustules and vesicles. Chancres and eczema like lesions are not indicative of genital herpes.
Disorders of the ovaries frequently cause ______and _____problems.
Menstrual, fertility
The___are analogous to the male scrotum.
Labia majora
The____ begin anteriorly at the hood of the clitoris and end posteriorly at the base of the vagina.
Labia minora
Commonly called fibroids.

Most women with polycystic ovary syndrome (PCOS) have elevated ____levels with normal estrogen and follicle-stimulating hormone (FSH) production.
Luteinizing hormone
Development of large, tender, and sometimes fluctuant inguinal lymph nodes called buboes.
Lymphogranuloma venereum
A male patient presents at the clinic with flu-like symptoms, weight loss of 10 pounds without trying. On physical examination, he is found to have splenomegaly and large, tender, fluctuant inguinal lymph nodes. While taking the nursing history, it is discovered that the patient prefers male sexual partners, and 2 weeks ago he had small, painless papules. What disease would the nurse suspect the client has?
Lymphogranuloma venereum (LGV). *Rationale:* An important characteristic of Lymphogranuloma venereum (LGV) is the early (1 to 4 weeks later) development of large, tender, and sometimes fluctuant inguinal lymph nodes called buboes.
Bartholin gland obstruction of the ductal system will cause a cyst. Sometimes the cyst becomes infected and an abscess occurs. What is the surgical procedure to remove a Bartholin cyst or abscess when a wedge of vulvar skin is removed along with the cyst wall?
Marsupialization. Rationale: Surgical treatment of a Bartholin cyst that has abscessed or blocks the entroitis is called marsupialization, aprocedure that involves removal of a wedge of vulvar skin and the cyst wall.
_________is inflammation of the breast.
Mastitis
What are the sex-specific manifestations of gonorrhea?
Men are more likely to be symptomatic than women. In men, the initial symptoms include urethral pain and a creamy yellow, sometimes bloody, discharge. The disorder may become chronic and affect the prostate, epididymis, and periurethral glands. Rectal infections are common in homosexual men. In women, rec- ognizable symptoms include unusual genital or urinary discharge, dysuria, dyspareunia, pelvic pain or tenderness, unusual vaginal bleeding (including bleeding after intercourse), fever, and proctitis. Symptoms can occur or increase during or immediately after menses because the bacterium is an intracellular diplococcus that thrives in menstrual blood but cannot survive long outside the human body. There may be infections of the uterus and development of acute or chronic infection of the fallopian tubes, with ultimate scarring and sterility.
Heavy bleeding during and between menstrual periods.
Meno-metrorrhagia
Cessation of menstrual cycles
Menopause
________ results from the gradual cessation of ovarian function and the resultant diminished levels of estrogen.
Menopause
Excessive menstrual bleeding.
Menorrhagia
Polycystic ovary syndrome is an endocrine disorder and a common cause of chronic anovulation. In addition to the clinical manifestations of PCOS, long-term health problems, including cardiovascular disease and diabetes, have been linked to PCOS. What drug has emerged as an important part of PCOS treatment?
Metformin.: Metformin, an insulin-sensitizing drug, used with or without ovulation-inducing medications, is emerging as an important component of polycystic ovary syndrome (PCOS) treatment. Dehydroepiandrosterone (DHEAS) is often found in the blood of women with PCOS; Methotrexate is used in ectopic pregnancies; Spironalactone, an an timineralocorticoid, is used in treating PCOS, not mineralocorticoids.
Bleeding between periods

Mucocutaneous
The___forms the major portion of the uterine wall.
Myometrium
The endocervix is covered with large branched mucous secreting glands. During the menstrual cycle, they undergo functional changes, and the amount and properties of the mucus that they secret varies according to the stage of the cycle. When one of these glands gets blocked, what kind of cyst forms within the cervix?
Nabothian cysts. Rationale: Blockage of the mucosal glands results in trapping of mucus in the deeper glands leading to the formation of dilated cysts within the cervix, called nabothian cysts.
Cervix
Narrow. lower portion of the uterus that opens into the vagina.
What are some of the known causes of erectile dysfunction?
Neurogenic disorders, such as Parkinson disease, stroke, and cerebral trauma, often contribute to erectile dysfunction by decreasing libido or preventing the initiation of erection. In spinal cord injury, the extent of neural impairment depends on the level, location, and extent of the lesion. Hormonal causes of erec- tile dysfunction include a decrease in androgen levels owing to both primary and secondary hypogonadism. Common risk factors for generalized penile arterial insufficiency include hypertension, hyperlipidemia, cigarette smoking, diabetes mellitus, and pelvic irradiation.
6. Herpes simplex virus type-1 and herpes simplex virus type-2 are _______viruses, meaning that they grow in neurons and share the biologic property of latency.
Neurotropic

Gonorrhea is an STI that affects both men and women. When diagnosing gonorrhea, specimens should be collected from the appropriate site and inoculated onto the correct medium. From what sites can specimens be collected when diagnosing gonorrhea?
Oropharynx; Urethra; Anal canal. *Rationale:* A specimen should be col- lected from the appropriate site (i.e., endo-cervix, urethra, anal canal, or oropharynx), inoculated onto a suitable medium, and transported under appropriate conditions. The nasal passages and the exocervix are not sites that would be used for the collection of Neisseria gonorrhoeae.
Consequences of long-term estrogen deprivation include ____ due to an imbalance in bone remodeling, and an increased risk for ____ disease, which is the leading cause of death for women after menopause.
Osteoporosis, Cardiovascular
_________tumors are common, most are benign, but malignant tumors are the leading cause of death from reproductive cancers.
Ovarian
What were the posited benefits of hormone replacement therapy? How has it been shown to be incorrect?
Over the past four to five decades, hormone therapy (HT) became increasingly prescribed for postmenopausal women. Initially, HT was used only for symptom management and later for prevention of osteoporosis. During the 1990s, HT evolved to the status of replacement for a vital hormone lost because of an endocrine organ failure (menopause). It was routinely offered to all postmenopausal women based on mounting evidence of preventive benefits in numerous areas. During this time, data from observational studies demonstrated a 50% reduction in coronary artery disease (CAD) mortality rates in women using HT. Other demonstrated advantages of HT included a reduced risk of Alzheimer disease, decreased risk of colon cancer, less tooth loss, and lower incidence of macular degeneration. Unopposed estrogen can lead to the development of endometrial hyperplasia which, in some cases, can increase a woman's risk for endometrial cancer. The Women's Health Initiative study to investigate the potential effects of HT was stopped after 5.2 years of data analysis when it was found that the risk of breast cancer crossed the predetermined safety boundary and it was determined that the risks of HT outweighed its benefits. In addition to breast cancer risk, CAD, stroke, and venous thromboembolic disease were all increased. On the positive side, a reduction was noted in colorectal cancer and hip fractures among the women using HT.
The most significant risk factor for ovarian cancer appears to be ________ -the length of time during a woman's life when her ovarian cycle is not suppressed by pregnancy, lactation, or oral contraceptive use.
Ovulatory age
________disease presents as an eczemoid lesion of the nipple and areola.
Paget

Parasympathetic, sympathetic
_____is a polymicrobial infection of the upper reproductive tract associated with sexually transmitted and endogenous organisms.
Pelvic inflammatory disease
Several risk factors for___ have been suggested, including increasing age, poor hygiene, smoking, human papillo- mavirus infections, ultraviolet radiation exposure, and immunodeficiency states.
Penile cancer.
In hypospadias, the treatment of choice is surgery to repair the defect. What influences the timing of the surgical repair? Mark all that apply.
Penile size, Psychological effects on a child, Aesthetic risk *Rationale:* Factors that influence the timing of surgical repair include anesthetic risk, penile size, and the psychological effects of the surgery on the child. In mild cases, the surgery is done for cosmetic reasons only. In more severe cases, repair becomes essential for normal sexual functioning and to prevent the psychological sequelae of having malformed genitalia. Testicular involvement and presence of an abdominal hernia have no bearing on the timing of the surgery.
Endometriosis is the condition where endometrial tissue is found growing outside of the uterus in the pelvic cavity. What are risk factors for endometriosis?
Periods longer than 7 days and increased menstrual pain. Rationale: Risk factors for endometriosis may include early menarche; regular periods with shorter cycles (<27 days), longer duration (>7 days), or heavier flow; increased menstrual pain; and other first-degree relatives with the condition. Late menarche, light flow, and periods shorter than 7 days are not risk factors for endometriosis.
The manifestations of what disease include painful erection, bent erection, and the presence of a hard mass at the site of fibrosis.
Peyronie
What involves a localized and progressive fibrosis of unknown origin that affects the tunica albuginea.
Peyronie disease
A 75-year-old man presents at the clinic complaining of pain during intercourse and an upward bowing of his penis during erection. His history includes an inflammation of the penis that was treated 3 months ago. The physician's physical examination of him notes beads of scar tissue along the dorsal midline of the penile shaft. What would be the suggested diagnosis for this patient?
Peyronie disease. *Rationale:* Peyronie disease involves a localized and progressive fibrosis of unknown origin that affects the tunica albuginea (i.e., the tough, fibrous sheath that surrounds the corpora cavernosa) of the penis The disorder is characterized initially by an inflammatory process that results in dense fibrous plaque formation. The plaque usually is on the dorsal midline of the shaft, causing upward bowing of the shaft during erection. The other answers are incorrect.

____ causes marked budding and growth of the alveolar structures.
Progesterone
The epididymis
Receives sperm from the testis and stores them while they develop further. sperm travel the length of the epididymis and then are ejaculated into the vas deferens.
________is the herniation of the rectum into the vagina.
Rectocele
3. What are the risk factors for developing a candidiasis infection?
Reported risk factors for the overgrowth of Candida albicans include recent antibiotic therapy, which suppresses the normal protective bacterial flora; high hormone levels owing to preg- nancy or the use of oral contraceptives, which cause an increase in vaginal glycogen stores; and uncontrolled diabetes mellitus or human immunodeficiency virus (HIV) infection, because they compromise the immune system.
1 . What are the risk factors for acquiring the human papillomavirus (HPV) and how is it spread?
Risk factors for acquiring the human papillomavirus (HPV) include young age (<25 years), early age of first intercourse (<16 years), increasing numbers of sex partners,and having a male partner with multiple sex partners. HPV infection can occur with any type of vaginal or anal penetration and is common in men having sex with men and women having sex with women. Oral-genital and manual-genital contact are less likely means of spreading this infection.
The sex-determining region of the Y chromosome
SRY gene
3. Priaprism (a prolonged painful erection not associated with sexual excitement) can occur at any age. In boys, ages 5 to 10 years, what are the most common causes of priapism?
Sickle cell disease or neoplasms. *Rationale:* Priapism can occur at any age, in newborn the as well as other age groups. Sickle cell disease or neoplasms are the most common cause in boys between 5 and 10 years of age. Hemophilia and hypospadias are not linked to priapism in any age group.
How do drugs like Viagra treat erectile dysfunction?
Sildenafil (Viagra) is a selective inhibitor of phosphodiesterase type 5 (PDE-5), the enzyme that inactivates cyclic guanosine monophos- phate (cGMP). This acts by facilitating corporeal smooth muscle relaxation in response to sexual stimulation.

Terconazole. *Rationale:* Antifungal agents, such as clotrimazole, miconazole, butaconazole, and ter- conazole, in various forms, are effective in treating candidiasis. These drugs, with the exception of terconazole, are available without prescription for use by women who have had a previously confirmed diagnosis of candidiasis.
What is testicular torsion? What are the different types?
Testicular torsion is a twisting of the spermatic cord that suspends the testis. Extravaginal torsion, which occurs almost exclusively in neonates, is the less common form. It occurs when the testicle and the fascial tunicae that surround it rotate around the spermatic cord at a level well above the tunica vaginalis. The torsion probably occurs during fetal or neonatal descent of the testes before the tunica adheres to the scrotal wall. Intravaginal torsion is considerably more common than extravaginal torsion. It occurs when the testis rotates on the long axis in the tunica vaginalis. In most cases, congenital abnormalities of the tunica vaginalis or spermatic cord exist. The tunica vaginalis normally surrounds the testes and epididymis, allowing the testicle to rotate freely in the tunica. Patients usually present in severe distress within hours of onset and often have nausea, vomit- ing, and tachycardia. The affected testis is large and tender, with pain radiating to the inguinal area.
6. In the neonatal and pediatric population, there can be many physiologic problems with the male genitourinary system. What is the most common acute scrotal disorder in the pediatric population?
Testicular torsion. *Rationale:* The most common acute scrotal disorder in the pediatric population is testicular torsion.
____is produced and secreted by the interstitial Leydig's cells in the testes.
Testosterone
____stimulates the wolffian ducts to develop into the epididymis, vas deferens, and seminal vesicles.
Testoterone
the uterine walls have three layers:
The Endometrium (lining) Myometrium (muscular layer) Perimetrium (outer covering which is continuous with the pelvic peritoneum). The endometrium proliferates (thickens & sloughs off in response to cyclic changes in levels of female sex hormones.
How does benign prostatic hyperplasia cause obstruction of the urethra?
The anatomic location of the prostate at the bladder neck contributes to the pathophysiology and symptomatology of benign prostatic hyperplasia (BPH). The two prostatic components to the obstructive properties of BPH and development of lower urinary tract symptoms are dynamic and static. The static component of BPH is related to an increase in prostatic size; it gives rise to symptoms such as a weak urinary stream, postvoid dribbling, frequency of urination, and nocturia. The dynamic component of BPH is related to prostatic smooth muscle tone. 1-Adrenergic receptors are the main receptors for the smooth muscle component of the prostate.
6. What is the clinical course of syphilis6. What is the clinical course of syphilis?
The clinical disease is divided into three stages: primary, secondary, and tertiary. Primary syphilis is characterized by the appearance of a chancre at the site of exposure. These lesions usually are painless and located at the site of sexual contact. The timing of the second stage of syphilis varies even more than that of the first, lasting from 1 week to 6 months. The symptoms of a rash, fever, sore throat, stomatitis, nausea, loss of appetite, and inflamed eyes may come and go for a year but usually last for 3 to 6 months. Secondary manifestations can include alopecia and genital condylomata latum. Condylomata latum are elevated, red-brown lesions that can ulcerate and produce a foul discharge. They are 2 to 3 cm in diameter, contain many spirochetes, and are highly infectious. Tertiary syphilis is a delayed response of the untreated disease. It can occur as long as 20 years after the initial infection. When syphilis does progress to the symptomatic tertiary stage, it commonly takes one of three forms: development of localized destructive lesions called gummas, development of cardiovascular lesions, or development of central nervous system lesions.
How are testicular cancers staged?
The clinical staging for testicular cancer is as follows: stage I, tumor confined to testes, epididymis, or spermatic cord; stage II, tumor spread to retroperitoneal lymph nodes below the diaphragm; and stage III, metastases outside the retroperitoneal nodes or above the diaphragm.
How is prostate cancer diagnosed?
The diagnosis of prostate cancer is based on history and physical examination and confirmed through biopsy methods. Transrectal ultrasonography is used to guide a biopsy needle and document the exact location of the biopsied tissue. Radiologic examination of the bones of the skull, ribs, spine, and pelvis can be used to reveal metastases. Prostatic-specific antigen (PSA) levels are important in the staging and management of prostatic cancer. In untreated cases, the level of PSA correlates with the volume and stage of disease.
the external female genitalia are
The mons pubis, labia majora, labia minora, clitoris, vestibule (urinary & vaginal openings), Bartholin glands, and Skene glands.
What is the mechanism of infection in pelvic inflammatory disease?
The organisms ascend through the endocervical canal to the endometrial cavity, and then to the tubes and ovaries. The endocervical canal is slightly dilated during menstruation, allowing bacteria to gain entrance to the uterus and other pelvic structures. After entering the upper reproductive tract, the organsms multiply rapidly in the favorable environment of the sloughing endometrium and ascend to the fallopian tube.
What measures should be taken to avoid vaginal infections?
The prevention and treatment of vaginal infections depend on proper health habits and accurate diagnosis and treatment of ongoing infections. Measures to prevent infection include those that keep the genital area clean and dry, maintenance of normal vaginal flora and healthy vaginal mucosa, and avoidance of contact with organisms known to cause vaginal infections. Perfumed products, such as feminine deodorant sprays, douches, bath powders, soaps, and even toilet paper, can be irritating and may alter the normal vaginal flora. Tight clothing prevents the dissipation of body heat and evaporation of skin moisture and promotes favorable conditions for irritation and the growth of pathogens. Cotton undergarments that can withstand hot water and bleach (a fungicide) may be preferable for women to prevent such infections.
The external male genitalia are
The testes, epididymides, scrotum, and penis.
Describe the functional anatomy of normal pelvic support.
The uterus and the pelvic structures are maintained in proper position by the uterosacral, round, broad, and cardinal ligaments. The two cardinal ligaments maintain the cervix in its normal position. The uterosacral ligaments hold the uterus in a forward position and the broad ligaments suspend the uterus, fallopian tubes, and ovaries in the pelvis. The vagina is encased in the semirigid structure of the strong supporting fascia. The muscular floor of the pelvis is a strong, slinglike structure that supports the uterus, vagina, urinary bladder, and rectum.
The internal female genitalia are
The vagina, uterus, fallopian tubes, & ovaries. All these organs are necessaty for reproduction; the ovaries are most essential because they produce the female gametes and female sex hormones.
The internal genitalia are
The vas deferens, ejaculatory duct, prostatic and membranous sections of the urethra, seminal vessicles, prostate gland, and Cowper glands.
Why should you be concerned about the future of your patient with polycystic ovarian syndrome?
There is also concern that women with PCOS who are anovulatory do not produce significant amounts of progesterone. This, in turn, may subject the uterine lining to an unop-posed estrogen environment, which is a significant risk factor for development of endometrial cancer. Although an association with breast cancer and ovarian cancer has been reported, PCOS has not been conclu- sively shown to be an independent risk factor for either malignancy.
Spirochete responsible for syphilitic infection
Treponema pallidum
______can reside in the paraurethral glands of both sexes.
Trichomonads
Anaerobic protozoan that can be transmitted sexually .
Trichomonas vaginalis
4. What are the potential complications of trichomoniasis in male and female patients?
Trichomoniasis is a risk factor for HIV transmission and infectivity in both men and women. In women, it increases the risk of tubal infertility and atypical pelvic inflammatory disease, and it is associated with adverse outcomes, such as premature birth in pregnant women.Trichomonads attach easily to mucous membrane. They can serve as vectors for the spread of other organisms, carrying pathogens attached to their surface into the fallopian tubes. In men, it is a common cause of non-gonococcal urethritis and is a risk factor for in- fertility, altering sperm motility and viability. It has also been associated with chronic prostatitis.
The breast cancer susceptibility genes, BRACA1 and BRCA2, which are ____ genes, are incriminated in approximately 10% of hereditary ovarian cancers despite being identified as breast cancer genes.
Tumor suppressor

Uterine prolapse
The____is a thick-walled muscular organ, located between the bladder and the rectum
Uterus
The____functions as a route for discharge of menses and other secretions.
Vagina
How and why is the vagina kept at an acidic pH?
Vaginal tissue usually is moist, with a pH maintained within the bacteriostatic range of 3.8 to 4.2. Glycogen is fermented to lactic acid by the lactobacilli (i.e., Döderlein's bacilli) that are part of the normal vaginal flora, accounting for the mildly acid pH of vaginal fluid.
_______represents an inflammation of the vagina that is characterized by vaginal discharge and burning, itching, redness, and swelling of vaginal tissues.
Vaginitis
. The ___is particularly susceptible to skin infections because it is constantly being exposed to secretions and moisture.
Vulva

a long coiled tube arranged in a comma-shapedcompartment that curves over the top and rear of the testis.
10. Although the cause of benign prostatic hyperplasia (BPH) is unknown, its incidence increases with age. In which ethnic group is BPH highest?
d. African American. *Rationale:* The incidence of benign prostatic hyperplasia increases with advanced age and is highest in African Americans and lowest in native Japanese.
8. Menopause signals the end of the menstrual cycle. It is caused by the end of ovarian function and the decreased levels of estrogen this brings to the body. What are problems that can arise from the onset of menopause? Mark all that apply. a. Nocturia b. Urinary stress incontinence c. Upper respiratory infection d. Vaginitis e. Urinary retention
a, Nocturia b, Urinary stress incontinence, d. Vaginitis. *Rationale:* Problems that can arise as a result of urogenital atrophy include vaginal dryness, urinary stress incontinence, urgency, nocturia, vaginitis, and urinary tract infection. URI, an upper respiratory infection, has nothing to do with menopause and urinary retention is not a problem that arises from menopause.
1. The female external genitalia are made up of several components. What is in the vestibule of the female external genitalia? a. Bartholin glands b. Skene glands c. Cowper glands d. Bulbourethral glands
a. Bartholin glands. *Rationale:* The area between labia minora is called the vestibule. Located in the vestibule are the urethral and vaginal openings and Bartholin's lubricating glands. The other an- swers are incorrect.

a. Gynecomastia b. Azoospermia d. Acne
8. Testicular cancer is highly curable if found and treated early. What are signs of metasta- tic spread of testicular cancer? Mark all that apply.
a. Hemoptysis b. Back pain c. Neck mass *Rationale:* Signs of metastatic spread include swelling of the lower extremities, back pain, neck mass, cough, hemoptysis, or dizziness. Gynecomastia (breast enlargement) may result from human chorionic go- nadotropin (hCG)-producing tumors and occurs in about 5% of men with germ cell tumors. The other answers are not signs of metastatic spread of a testicular cancer.
10. Lactation occurs under the control of the anterior pituitary hormone prolactin. What causes the ejection of milk from the ductile system in the breast? a. Oxytocin b. Prolactin c. Estrogen d. Progesterone

b. Chlamydia trachomatis and Neisseria gonorrhoeae. *Rationale:* Sexually transmitted acute epididymitis occurs mainly in young men without underlying genitourinary disease and ismost commonly caused by Chlamydia trachomatis and Neisseria gonorrhoeae. Candida albicans and Escherichia coli are not the most common causes of epidiymitis in young men without underlying genitourinary disease.
Ovarian events of the menstrual cycle are controlled by
gonadotropins. High FSH levels stimulate follicle and ovum maturation (follicular phase); then a surge of LSH causes ovulation, which is followed by development of the corpus luteum (luteal phase).
6. The ovaries secrete both estrogen and progesterone. What is one function of progesterone in the body? a. Causes moderate retention of sodium and water b. Increases body temperature at ovulation c. Reduces levels or rennin d. Enhances the coagulability of blood
b. Increases body temp at ovulation. *Rationale:* Although the mechanism is un- certain, progesterone increases basal body temperature and is responsible for the in- crease in body temperature that occurs with ovulation. The other answers are effects of estrogen.
2. Estrogen stimulates the vaginal wall to thicken and increase the secretion of glyco- gen. What causes the glycogen in the vagina to ferment to lactic acid? a. Escherichia coli b. Döderlein's bacilli c. Candida albicans d. Staphylococcus aureus
b.Doderlein's bacilli. *Rationale:*The glycogen is fermented to lactic acid by the lactobacilli (i.e., Döderlein's bacilli), which are part of the normal vaginal flora, accounting for the mildly acid pH of vaginal fluid. The other answers are incorrect.
9. A 40-year-old man presents at the clinic complaining of painful urination and rectal pain. His vital signs are as follows: temperature 101.7F; blood pressure 105/74 mm Hg; pulse98; respiratory rate 22. While taking a history, you note that the patient has had chills, malaise, and myalgia. What would you suspect as a diagnosis?
c. Acute bacterial prostatitis. *Rationale:* The manifestations of acute bacterial prostatitis include fever and chills, malaise, myalgia, arthralgia, frequent and urgent urination, dysuria, and urethral discharge. Dull, aching pain often is present in the perineum, rectum, or sacrococcygeal region. The other answers are incorrect.
7. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) produce profound effects on the ovaries. What do high levels of estrogen do to FSH and LH? a. cFSH and TLH b. cLH and Testradiol c. c LH and T FSH d. c FSH and T renin
c. LH & T FSH. *Rationale:* High levels of estrogen exert a negative feedback effect on FSH, inhibiting multiple follicular development and causing an increase in LH levels. The other answers are incorrect.
3. The perimetrium reflects over the bladder wall and forms what? a. Opening to fallopian tubes b. The external cervical os c. The pouch of Douglas d. Bartholin's pouch
c. The pouch of Douglas. *Rationale:* Anteriorly, the perimetrium is reflected over the bladder wall, forming the vesicouterine pouch; posteriorly, it extends to form the cul-de-sac, or pouch of Douglas. The other answers are incorrect.
The ______is a pyogenic (i.e., pus-forming) gram-negative diplococcus that evokes inflammatory reactions characterized by purulent exudates.
gonococcus
4. The fallopian tubes are narrow tubes that attach bilaterally to the uterus. Within the fal- lopian tube, fertilization of the ovum takes place.

Oviducts c. Cilia d. Fimbriae
d. Fimbriae. *Rationale:* The end of the fallopian tube nearest the ovary forms a funnel-like opening with fringed, finger-like projections called fimbriae, which pick up the ovum after its release into the peritoneal cavity after ovulation. The other answers are incorrect
9. What are the small bumps or projections on the areolar surface called? a. Cowper cells b. Bartholin gland c. Climacteric glands d. Montgomery tubercles
d. Montgomery tubercles. *Rationale:* The small bumps or projections on the areolar surface known as Montgomery's tubercles are sebaceous glands that keep the nipple area soft and elastic. The other answers are incorrect.
The normal vaginal ____depends on the delicate balance of hormones and bacterial flora.
ecology
The average menstrual takes 37 to 30 days & consists of three phases
follicular/proliferative phase, luteal/secretory phase, and menstruation. Named for endometrial changes.
The male____ system is composed of the paired gonads, or testes, genital ducts, accessory organs, and penis.
genitourinary
The scrotum
is a skin-covered fibromuscular sac that encloses the testes and epididymides, which are suspended within the scrotum by the spermatic cord.
The Uterus
is the hollow, muscular organ in which a fertilized ovum develops until birth.
The scrotum
keeps these organs at optimal temperatures for sperm survival (about1 to 2 degrees centigrade lower than body temperature) by contracting in cold environments and relaxing in warm environments.
Uterine ____are benign neoplasms of smooth muscle origin.
leiomyomas
During ______, the newly developed squamous epithelial cells of the cervix are vulnerable to development of dysplasia and genetic change if exposed to cancer producing agents
metaplasia
. Parasympathetic stimulation results in release of ____, which causes relaxation of trabecular smooth muscle of the corpora cavernosa, permitting inflow of blood into the sinuses of the cavernosa at pressures approach- ing those of the ______system?.
nitric oxide, arterial erectile dysfunction.
Uterine (endometrial) events of the menstrual cycle are caused by
ovarian hormones. During the follicular phase of the ovarian cycle, estrogen produced by the follicle causes the endometrium to proliferate (proliferative phase). During the luteal phase, estrogen maintains the thickened endometrium, while progesterone causes it to develop blood vessels and secretory glands (secretory phase). As the corpus luteum degenerates, production of both hormones drops sharply, and the "starved" endometrium degenerates and sloughs off, causing menstruation.
The____ is a fibromuscular and glandular organ lying just inferior to the bladder.
prostate
The female sex hormones are involved in
sexual differentiation and development, the menstrual cycle, pregnancy, and lactation.
The structure and function of both male and female reproductive systems are controlled by
the hypothalamic-pituitary-ovarian axis, a set of complex neurologic & hormonal interactions that accelerate at puberty, causing sexual maturation and making reproduction possible.
Extra hypothalamic factors cause
the hypothalamus to secrete gonadotropin-releasing hormone (GnRh), which stimulates the anterior pituitary to secrete gonadotropin-follicle-stimulating hormone (FSH) & luteinizing hormone (LH)--which stimulate the gonads (ovaries or testes) to secrete female or male sex hormones.
Cyclic changes in hormone levels also cause thinning and thickening of the vaginal epithelium,
thinning and thickening of cervical secretions, and changes in basal body temperature.
