American sex educator, nurse, and birth control activist. Sanger opened the first birth control clinic in the United States and established Planned Parenthood. Sanger's efforts contributed to the landmark US Supreme Court case which legalized contraception in the US.

Vaginal opening

An introitus is thus an entrance, one that goes into a canal or hollow organ such as the vagina

Zona Pellucida

cervix

Opening/lubrication - It is the lower most part of the uterus and is made up of strong muscles. The function of the cervix is to allow flow of menstrual blood from the uterus into the vagina, and direct the sperms into the uterus during intercourse. The opening of the cervical canal is normally very narrow.

*decidua capsularis

parental influences: inoculation boosters, self-esteem, self-worth,

Parents can give gentle reminders about what is appropriate and adolescents will also tend to make better choices if confident (re drugs, alcohol, and sex).

vas deferens

Passageway - Long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. Transports mature sperm to the urethra, the tube that carries urine or sperm to outside of the body, in preparation for ejaculation.

Fallopian tubes

Passageway - The uterine tubes, also known as oviducts or Fallopian tubes, are the female structures that transport the ova from the ovary to the uterus each month. In the presence of sperm and fertilization, the uterine tubes transport the fertilized egg to the uterus for implantation.

urethra

Passageway - Tube that carries urine from the bladder to outside of the body. In males, it has the additional function of ejaculating semen when the man reaches orgasm. When the penis is erect during sex, the flow of urine is blocked , allowing only semen to be ejaculated at orgasm.

Vagina

Passageway/lubrication - The inner lining of the vagina is made of non-keratinized stratified squamous epithelial tissue. This tissue provides protection from friction to the underlying layers of the vagina. Watery secretions produced by the vaginal epithelium lubricate the vagina and have an acidic pH to prevent the growth of bacteria and yeast. The acidic pH also makes the vagina an inhospitable environment for sperm, which has resulted in males producing alkaline seminal fluid to neutralize the acid and improve the survival of sperm.

Clitoris

Pleasure - Small projection of erectile tissue in the vulva of the female reproductive system. It contains thousands of nerve endings that make it an extremely sensitive. Touch stimulation of the nerve endings in the clitoris produces sensations of sexual pleasure. It is structurally and functionally homologous to the penis of the male reproductive system, except that the clitoris does not contain the urethra and plays no role in urination.

Endometrial Cycle - physiology

Prepares for pregnancy (receive/nourish zygote) -1st thickens, becomes succulent (rich, velvety cushion of new blood vessels et tissue) -after ovulation, continues to develop d/t progesterone secreted by corpus luteum

Ovaries

Product ova/hormones - The ovaries have two main reproductive functions in the body. They produce oocytes (eggs) for fertilization and they produce the reproductive hormones, estrogen and progesterone.

*NST-nonstress test

Reactive - 2 accelerations ( 15 BPM x 15 sec.) with fetal movement in a 10-20 min. window (FAVORABLE) Nonreactive - less than acceptable accelerations with fetal movement, after 40 minutes (UNFAVORABLE) Unsatisfactory - poor quality tracing, repeat same day

seminal vesicles

Secretion/motility - Sac-like pouches that attach to the vas deferens near the base of the bladder. They produce a sugar-rich fluid that provides sperm with a source of energy to help them move. This fluid of the makes up most of the volume of a man's ejaculate.

Mirena IUD

Corona Radiata

The corona radiata surrounds an egg and consists of two or three layers of cells from the follicle (secretes estrogen). They are attached to the zona pellucida - the outer protective layer of the egg - and their main purpose is to supply vital proteins to the cell.

Cytoplasm

The cytoplasm is a gel-like substance that holds all the cell's other internal structures, called organelles. It is in the cytoplasm that all the cell's activities take place to keep it alive and functioning properly.

Nucleus

The nucleus is the heart of the egg cell; it contains most of the genetic material in the form of chromosomes. This is where the genes are situated and contains half the number of chromosomes as a normal cell (23 each).

ejaculatory duct

These are formed by the fusion of the vas deferens and the seminal vesicles (see below). The ejaculatory ducts empty into the urethra.

Embryonic/fetal membranes 1. 2. 3.

These begin before implantation 1. chorion - outer membrane 2. amnion - inner membrane 3. amniotic cavity - space between amnion et embryo The amnion expands as embryo grows until contacts chorion. Amniotic fluid is secreted from amnion, then, later from maternal plasma et fetal unit.

Testicular torsion

Twisted spermatic cord 1. Stimuli - can be caused by a congenital abnormality of the covering of the testes, but usually trauma. 2. Management -EMERGENGY. Must have SURGERY within 4-6 hours or the testicle will die. -Salvage rate is 90% -If it occurs prenatally there is no testicular viability

Placentation (implantation)

forms @ place of attachment to uterine wall a. layers - trophoblast divides into 2 layers (maternal & fetal) - side of placenta b. cotyledons - as pg. progresses 3rd layer of connective Mesoderm develops forming cotyledon (15-20 segments) - a complex vascular system through which exchange of gases et nutrients occurs [Ctyledons are sections of placental chunks that are a redundant system. It is about 8" diameter and weighs 1 lb.]

history abdominal and pelvic exam laparoscopy

Scrotum

holds testicles/temperature regulation - It contains the testicles (also called testes), as well as many nerves and blood vessels. The scrotum acts as a "climate control system" for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than body temperature.

lines the rest of the uterine cavity

Endometriosis stimuli

menstrual reflux transport through lymph or blood transplantation at time of surgery

Proximal to distal

midline to limbs

genitourinary organs 7-8 week fetus

more differentiation

Fertilization

occurs when ovum reaches the ampulla of the fallopian tube, usually, et 1 sperm penetrates the ovum's nucleus instantly the ovum becomes impenetrable to other sperm and development begins.

Endometriosis sites

ovaries tubes ligaments colon bladder vagina cervix surgical incision

Injections - Inhibits _______ example: ________________

ovulation Depo-Provera (IM progestin q12 weeks)

Penis

passageway/sensation - The penis functions as both a reproductive organ and an excretory organ. As a reproductive organ, the penis becomes erect during sexual intercourse in order to deliver semen more effectively into the vagina. Semen travels through the urethra to the tip of the penis where it is ejaculated out of the body.

G-spot

pleasure/sensation - The G-spot, also called the Gräfenberg spot. Characterized as an erogenous area of the vagina that, when stimulated, may lead to strong sexual arousal, powerful orgasms and potential female ejaculation.[1] It is typically reported to be located 5-8 cm (2-3 in) up the front (anterior) vaginal wall between the vaginal opening and the urethra and is a sensitive area that may be part of the female prostate.

Zygote

pre-embryonic - 0-3 weeks

testes

produce sperm/hormones - The primary functions of the testes are to produce sperm (spermatogenesis) and to produce androgens, primarily testosterone. Both functions of the testicle are influenced by gonadotropic hormones produced by the anterior pituitary. Luteinizing hormone (LH) results in testosterone release.

Labia majora

protection/sensation - The function of the labia majora is to enclose and protect the other external reproductive organs.

Labia minora

protection/sensation - The labia minora are a pair of thin cutaneous folds that form part of the vulva, or external female genitalia. They function as protective structures that surround the clitoris, urinary orifice, and vaginal orifice.

Mons Pubis

protection/sensation - The mons pubis is a rounded mound of fatty tissue that covers the pubic bone. During puberty, it becomes covered with hair. The mons pubis contains oil-secreting (sebaceous) glands that release substances that are involved in sexual attraction (pheromones).

geturouniary organs in a 5-6 week week old embryo

sexually indifferent stage

Pregnancy: genital/cervix changes: Goodell's

soft cervix

Pregnancy: genital/cervix changes: Ladin's

soft mid-uterus

Curiosity

toddlerhood, three years old, curious about how their bodies work or self calm and pleasurable feeling (sex play)

Sterilization female

tubal ligation: blocks sperm from traveling down Fallopian tube to egg (Permanent: 70% reversal success rate) trans-cervical: "Essure" coil placed in each Fallopian tube, failure rate <1%

Cryptorchidism

undescended testes-often retractile 1. Stimuli-premature, genetic hernia 2. Dx-palpation, U.S., laparoscopy, "milk" retractile 3. Mgnt-hormone therapy, surgery (orchiopexy between 1-3 y/o as out-patient)

Sterilization male

vasectomy: cutting & closing of vas deferens prevents sperm from being ejaculated with semen Permanent: 50% pregnancy rate after reversal

peer influences are ____ _________.

very important - video "she probably wants it"
