Gold standard for diagnosing osteoporosis
DXA (Dual-energy X-ray absorptiometry) of lumbar spine and hip
Injectable Progeserone-Only Contraception MOA
Depo-Provera (Depot medroxyprogesterone acetate, DMPA) (150 mg/1 mL, intramuscular "IM") injected IM every 3 months in vehicle that allows slow release of progestin over 3-month period low-dose DMPA (104 mg/.65 mL, subcutanoues "SC") also available, not widely used yet -benefits: lower progestin levels but same efficacy acts by: 1. suppressing ovulation 2. thickening the cervical mucus 3. making endometrium unsuitable for implantation 4. reducing tubal motility after injection, ovulation does not occur for 14 weeks, pts have 2 wk grace period in their every every 12-week dosing
Effectiveness of tubal ligation
FR= 0.3% , but varies by method, pt age, and surgeon experience
When are symptoms of menopause often most intesnse?
during late perimenopause phase gradually, most women will see reduciton in severity of these symptoms over time avg medial duration of reported VMS symptoms is 7.5 yrs
When do women achieve maximum bone density?
20-25 yrs t/f achieving max bone density is critical to the care for female pts at all ages -low vit D can result in osteomalacia in adults and rickets in chidlren -diets low in Ca assoc. w/ low bone mineralization
traditional combination pill
conains both estrogen and progestin - taken for 1st 21 days out of 28-day monthyl cycle during last 7 days of cycle, placebo pill or no pill is taken bleeding should begin within 3-5 days of completion of 21 days of hormones
Duavee
conjugated equine estrogen (CEE) 0.45mg and bazedoxifene (BZE) 20 mg), the first TSEC approved to treat VMS and prevent osteoporosis in women with intact uterus doesn't require addition of progesterone SERMs have unique pattern of both agonistic and atnagonistic effects on other tissues, including heart, bone, uterus, and breast only BZE has been shown to have an adequate antagonistic effect on uterus; therefore; it does not require additional progesterone therapy when paried with an estrogen
Once the diagnosis of osteoporosis is made, what should be done? what is recommended for them?
consider 2* causes and work up prior to initiating tx women w/ OP and those at risk for OP should be encouraged to make lifestyle changes to decrease their risk weight-bearing exercise (walking, hiking, stair climbing) and muscle-strengthening exercise have been found to decrease risk of falls and fractures counsel for adequate Ca and Vit D intake reduce active and passive smoking and alcohol intake (<3/day) use fall prevention strategies to limit risk of falls and fxs
With which option are highest success rates acheived?
1. PPS 2. Essure tubal occlusion
MOA of transdermal patch (Estrogen exposure + increased risk of?)
(Ortho Evra Patch, Xulane) contains both P and E releases 150 mg/day of progestin, norelgestromin, and 35 mg/day of EE overal avg estrogen exposure is 60% higher in patch user compared w/ women taking standard 25 mcg OCP t/f these pts should be made aware of increased risk of thromboembolism, specifically DVT and PE in Ortho Evra users compared w/ women taking standard OCPs there does not appear to be increased risk of heart attack and stroke in these pts 1. women apply one patch on same day each weak (patch change day) for 3 consecutive weeks by a 1-week patch-free period where they will have a withdrawal bleed can be worn on upper outer arm, abdomen, buttock, or back in a location that would not be disturbed by clothing patch should NOT be placed on breasts primary MOA is suppression of ovulation by decreasing endogenous FSH and LH levels, thickening ervical mucus, and thinning the endometrium (like combined OCPs)
3 forms of ECPs
(aka post-coital or morning-after pill) 1. Copper T IUD (ParaGard) -emergently inserted 2. SPRM (selective progesterone receptor modulator, uliprastil or Ella) 3. Mifepristone (RU 486) -approved in US for termination of preg up to 49 days of gestation, not approved for EC
Two-Cell Theory
(aka two-cell, two-gonadotropin theory) Postulates role of both FSH and LH (two gonadotropins) on ovarian follicular maturation and the production of estrogens involving both theca and granulosa cells (two cells) 1. LH stimualtes production of androgens (androstenedione) from cholesterol and prenenolone in theca cells 2. Androgens transported into granulosa cells where FSH stimulates the conversion of androgens to estrogens (estroen) 3. As rising estrogen levels have negative feedback on pituitary FSH secretion, dominant follicle is protected from decrease in FSH by its increased number of FSH receptors
two long-term consequences of menopause
(consequences of estrogen-deficient state) 1. CV -protective benefits of estrogen on lipid profile (increased HDL, decreased LDL and TGs) -protective on vascular epithelium (decreased atherogenesis, increased vasodilation, decreased platelet adherence) -these are lost -increased risk for CAD 2. Low Bone Density -formerly osteopenia, potentially osteoporosis -bone resportion increases
Multiphasic oral contraceptives
(dose varying) differ from monophasic only in that they vary the dosage of estrogen and/or progestin in active hormone pils in effort to mimic menstural cycle advantage=may provide lower level of estrogen and progestin overall, but highly effective at preventing preg
What may women with menstrual-related disorders benefit from?
(endometriosis, heavy menstural periods, anemia, dysmenorrhea, mesntrual irregularity, menstural migranines, PMS, PCOS, ovarian cysts) may benefit from extending # of consec days of hormonal pills taken from 21 days-1, 2, or 3 months, thus increasing length of continuous hormonal suppression and decreasing the # of withdrawal bleeds extended or long-cycle regimens (Seasonale and Seasonique) provide continued suppression of ovulation and decreased menstrual-related symptoms (such as pain, heavy bleeding, cysts, anemia, and headaches for users also good for women who prefer to have fewer withdrawal bleeds while taking OCPs
monophasic combination pills
(fixed dose) combination pills -fixed dose of estrogen (20-35 mcg of ethinyl estradiol EE) -fixed dose of progestin
Perimenopause (aka?)
(menopausal transition) transition from normal ovulatory cycles to menopause b/c of progressive ovarian failure symptoms can begin from 2-8 yrs prior to final menstural period (FMP) time from FMP and beyond is considered postmenopausal menopausal transition and early postmenopausal years are when women have their most significant symptoms
Continuous regimens
(such as Lybrel) with a daily hormone pill and no hormone free interval have been found to be safe and effective
Interactions of OCPs (meds that reduce efficacy of OCPs vs. meds whose efficacies are changed by OCPs)
**only antibiotic that lower effectiveness of OCPs is Rifampin CDHMPTT
thelarche
*usually first phenotypic sign of puberty 1. development of breast buds (around 10 yrs) -occurs in response to increase in levels of ciruclating estrogen 2. coestrogeniation of vaginal mucosa and growth of vagina and uterus 3. further breast development continues thruout puberty and adolesence (Marshall and Tanner)
Side Effects of OCPs
.OCPs w/ estrogen doses >50 mg can increase coagulability -> higher rates of MI, stroke, DVT, and PE, particularly in women who smoke even at lower doses of estrogen (35 mcg or less), women >35 yrs who smoke >15 cigs/day are still at ^ risk of heart attack, stroke, DVT, and PE if they use OCPs
Effectiveness of Transdermal Patch
1% pregnancy rate in actual use -- similar to other combo hormonal methods transdermal patch has been found to have a decreased effectiveness in women weight more than 198 lbs (90kg)
Effectiveness of Depo-Provera
1. 1st yr theoretical failure rate of only 0.3% -one of most effective contraceptions avaialble 2. typical use FRs ~3%, mostly attributed to pts failiing to return at scheduled times for follow-up injections
Medications for Tx of OP
1. Bisphosphonates -leading tx -MOA: inhibiton of osteoclast resorption of bone 2. partial estrogen agonists/antagonists -inhibit bone resorption (aka SERMs) 3. denosumab (Prolia) -human mAb to receptor activator of NFkB ligand, which blocks proliferation and differentation of osteoclasts, resulting in decreased bone resorption and increased BMD 4. teriparatide (Forteo) 5. Calcitonin -Antiresorptive tx 6. PTH -stimualtes osteoblastic activity 7. MHT
initial workup for delayed or precocious puberty
1. Careful hx 2. PE 3. hormone assessment 4. bone age determination
Menstruation in more detail
1. During folluicular phase, endometrium in proliferative phase (growing in response to estrogen) 2. During luteal phase, endometrium in secretory phase (as it matures and is prepared to support implantation) 3. If ovum not fertilized, CL deg after approx 14 days, leading to fall in esrogen and progesterone levels 4. withdrawal of progesterone -causes endometrium to slough, initiating menstrual phase 5. At same time, FSH levels begin to slowl rise in absence of negative feedback, and the follicular phase starts again 6. Menstrual cycle <24 days or >34 days or a menses that lasts > 7 days merits further eval
Ovulation in more detail
1. Estrogen levels eventually surge to reach a critical level that triggers the anterior pituitary to release an LH spike 2. LH surge triggers the resumption of meiosis in the oocyte and induces production of progesterone and prostaglandins, which are repsonsible for rupture of ofllicular wall with release of mature ovum or ovulation 3. Ovum usually passes into adjoining fallopian tube and swept down to uterus by cilia -takes 3-4 days 4. fertilization of ovum must occur within 24 hrs of ovulation or it degenerates
Luteal phase in more detail
1. Granulosa and theca interna cells lining the wall of the follicle form the corpus luteum under stimulation by LH 2. The corpus luteum makes estrogen and significant quantities of progesterone, causes endometrium to become more glandular and secretory in prep for implant of fertilized ovum 3. If fertilization occurs, developing trophoblast synthesizes human chorionic gonadotropin (hCG) (glycoprotein v similar to LH, which maintains corpus luteum, so that it can continue production estorgen and progesterone to support the endometrium) 4. this continues untilt he placenta develops its own synthetic function at 8-10 wks of gestation 5. if fertilization, with its concomitant rise in hCG, does not occur, the CL degenerates 6. progesterone falls 7. endometrium not maintained -> menstruation
Effectiveness of IUDs
1. IUD effecicacy rivals permanent sterilization w/ prolonged use 2. Failure rate 0.8% for Paragard and 0.2% for Mirena within 1st year 3. 10 year failure rate for ParaGard ~1.9% 4. cumulative 5yr FR for Mirena ~0.7%
Physiology of perimenopause
1. Inhibin B secretion from granulosa cells falls b/c of diminished follicular numbers 2. FSH rises 3. progesterone levels low 4. estradiol levels fluctuate greatly, but in general preserved until late perimenopause when both estradiol and FSH ca fluctuate
Menopause Symptoms
1. Vasomotor symptoms (VMS) -night sweats -daytime hot flashes 2. mood swings -irritability -depression -anxiety 3. insomnia 4. sleep disturbances 80% of women experience them at some point during transition various physiolgoic changes due to decrease in estorgen 40-80% of women will begin having mild symptoms during perimenopause 50% will experience an increase in freq and intestnsity of symptoms during menopause transition
Diaphragm (MOA, Effectivness, Side Effects, Ads/Dis)
1. MOA -dome-shaped shallow cup made of a soft silicone or latex (rubber) sheet which is stretched over thin coiled rim -spermicidal gel, foam, or cream is placed on rim and on either side of diagpraghm -> placed into vagina and left in place after intercourse for minimum of 6 hrs (max of 30 hrs) -if further intercourse is to take place w/in 6-8 hrs after 1st episode, additional spermicie should be placed in vagina without removing 2. Effectiveness -theoretical effectiveness ~94% -actual effectiveness rate = 80-85% 3. Side Effects -bladder irritation-> UTIs -if in too long -> toxic shock syndrome (S. aureus colonization) -hypersensitivity to rubber, latex, or spermicide 4. Ads/Disad -safe, effective, convenient -must be fitted/prescribed -initial cost slightly higher than OCP contraception -should be placed every 2 yrs or when pt gains or loses more than 20% of body weight -fit should be checked after each pregnancy -if uncomfortable inserting and removing or cannot be properly fitted b/c pelvic relaxation defects AND women at high risk of HIV = poor candidates -used by less than 1%, few options on market
Periodic abstience (MOA, Effectiveness, Advantages/Disadvantages)
1. MOA -rhythm or calednar method -physiologic form of contraception, emphasizes fertility awareness and abstience (shortly before and after ovulation period) -requires instructions on determining ovulation -requires woman have regular, predictable menstrual cycles -kits include basal body temp measurements, menstrual tracking, cervical mucus evaluation, 2. Effectiveness -relatively low (55-80%) 3. Ad/Dis -no chemicals/mechanical barriers -need motivated couple willing to learn -relatively unreliable, may require longer periods of abstinence
Lactational amenorrhea (MOA, Effectiveness, Ads/Dis)
1. MOA -Continuation of breastfeeding -after delivery, restoration of ovulation delayed b/c breastfeeding-induced hypothalamic suppression of ovulation -prolactin-induced inhibition of pulsatile GnRH from hypothalamus (specifically) 2. Effectiveness -highly variable duration of ovulatory supression -50% of lactating mothers begin to ovulate between 6-12 mo post delivery, even when breastfeeding -return of ovulation occurs BEFORE return of mensturation (15%-55% using lactation for contraception become pregnant) -can be enhanced for short-term use by: a) using breast milk as only form of nutrition for infant B) only used as long as woman is experiencing amenorrhea, and even then only 6 mo after delivery 3. Ads/Dis -no effect on breastfeeding -safe, simple, free -increased body contact/bonding for baby, lower infection (maternal Abs) -limited to immediate 6 mo after delivery -can result in vaginal dryness -theortical failure rates reasonable, but actual practice are high and unacceptable
Cervical Cap (MOA, Effectivness, Ads/Dis) - most common cause of failure?
1. MOA -FemCap or Lea Shield -small, soft, silicone cap that fits directly over cervix -held in place by suction, barrier sperm -fitted by a clinician (proper fit essential to effectiveness) -must be used w/ sperm gel, foam, or cream -widely used in Britain and Europe, not widely available in US 2. Effectiveness -Actual effective rate= 68-84% (16-32% failure rate) -increased risk of failure in parous women -mcc of failure= dislodgment 3. Ads/Dis -small/immediately effective -does not interfere w/ endogenous hormones, can use while breastfeeding -can be inserted up to 6 hrs prior to intercourse, so it does not interrupt sex -can be left in place 1-2 days -foul discharge often develops after 1st day -must be refitted after preg or in event of large weight change -difficulty to place and remove -> continuation rate is low (30-50%)
Female Condoms (MOA, Effectieness, Ads/Dis)
1. MOA -female condom (FC2 Female COndom) aka internal condom = pouch made of synthetic nitrile (previously polyurethane) w/ flexible ring at each end -one ring=silicon and lubricated -inserted into depth of vagina near introitus -can also be inserted into anus 2. Effectiveness -TFR=5% -AFR=20-25% (somewhat higher than male condoms) 3. Ads/Dis -protect against STIs -stays in place even if male erection is lost -cost and overall bulkiness/decreased sensation -irrtation -acceptability rating is somewhat higher for male than female
Male Condoms (MOA, Effectiveness, Side Effects, Ads/Dis)
1. MOA -latex sheathes placed over erect penis before jeaculation 2. Effectiveness -actual efficacy rate in population is 85-90% -important to leave a well at tip to collect ejaculate and avoid leakage of semen as the penis is withdrawn -efficacy is also increased by use of spermicide-containing condoms or by using spermicide along w/ condoms 3. Side Effects -hypersensitivity to latex, lube, or spermicide in condoms 4. Ads/Dis -widely available -low cost -prevent STIs - only contraceptive protecting against HIV -dis: coital interruption, decreased sensation, hypersensitivity
Spermicides (MOA, Effectivness, Side Effects, Ads/Dis) - Contraindication?
1. MOA -most widely used = 1) nonoxynol-9, 2) octoxynol-9 -disrupt cell membranes of spermatozoa, also act as mechanical barrier to cervical canal -should be placed in vag at least 30 min before intercourse to allow for dispersion thruout vagina -may be used alone but more effectve in conjuction w/ other forms 2. Effectiveness -when properly and consistently used w/ condoms (95% effective rate) -actual use = 70-75% (reduced by failure to wait lone nough for spermicide to disperse in vag prior to intercourse) 3. Side Effects -irritation of vaginal mucosa and external male and female genitalia 4. Ads/Dis -various forms (creams, gels, films, suppositories, foams) -inexpensive -messy -do not protect against STIs -may make user more susceptible to STIs (including HIV by causing vaginal irritation) -do not use in women w/ HIV or at high risk of contracting HIV -general public: recommend consistent condom use to protect against STIs
Cotius interruptus (MOA, Effectiveness, Advantages/Disadvantages)
1. MOA -withdrawal of penis from vagina b/f ejaculation 2. Effectiveness -high failure rate (27%) -failure due to: 1) pre-ejaculate in vagina before orgasm 2) deposition of semen near introitus after intracrural intercourse 3. Ads/Dis -high failure rate -need for sufficient self-control
Recommendations for MHT Use
1. Moderate to Severe VMS or GSM and no contraindication to estrogen (MHT) 2. prevention of osteoporosis, but NOT treatment of osteoporosis (MHT) 3. only have symptoms relating to GSM, local, low-dose vaginal estrogens recommended 4. Doses = lowest effective dose -individualization -route of admin/types of estrogen/progest used or use of TSEC or SERM should be considered
pubertal sequence
1. accelerated growth 2. breast development (thelarche) 3. development of pubic and axillary hair (pubarche) 4. onset of mestruation (menarche) usually occur in order concerned pts can be reassured by knowing that on average the length of time from breast bud dev to menstruation is typically 2.5 years

Etiology of Menopause - what is menopause generally heralded by?
1. generally heralded by menstural irregularity b/c the # of oocytes decreases 2. increasingly sporadic ovulation 3. commonly believed that, as part of nautral aging process, the onset of menopause is caused by disruption in function of HPO axis and gradual oocyte depletion (follicular atresia). 4. Causes decrease in estrogen production and increase in FSH and LH
In whom is menarche often delayed?
1. gymnasts 2. distance runners 3. ballet dancers theories: -insufficient % of body fat that may result in hypothalamic anovulation and amenorrhea -exercise and stress on body may inhibit ovulation thru + effects of NE and GnRH, thus interfering with menarche
ECP MOA
1. high doses of both estrogen and progestins or progesterone alone (Plan B One Step, Next Choice) 2. Sreveral dif regimens -higher doses of regularly prescribed OCPs 3. LNG methods are preferred over estrogen-progesterone regimens -LNG=more effective + fewer side effects (decrease N/V)
Advantages/Disadavantages of IUD
1. prescribed 2. inserted by dr 3. removed by dr 4. rapidly reversible 5. monthyl string check to ensure it hasn't been expelled (imrpoves coital spontaneity and decreases fear of pregnancy) 6. in US, ParaGard IUD has been approved for use for 10 yrs (but effective up to 12 yrs) 7. Mirena IUD approved for 5 years (but effective for at least 7 yrs) 8. Liletta and Sykle currently up to 3yrs 9. Kyleen (5-year LNG IUD) 10. one IUD can be removed and another inserted on same visit 11. may be inserted immediately after induced or spontaneous first trimester abortions w/o increased risk of infeciton/performation
Luteal Phase
1. remnants of follicle left behind in ovary develop into corpus luteum (secrtes progesterone), which maintains endometrial lining in prep to receive fertilized ovum
ads/disads for transdermal patch
1. safe 2. effective 3. convenient 4. bleeding generally lighter and shorter on hormonal contraceptives same 1* side effects and noncontraceptive health benefits of OCPs apply to patch 5. can cause skin irritation 6. added benefit of being self-administered only once a week
Emergency Contraception (EC)
1. safe effective means of prevention after unprotected intercourse or in case of contraceptive failure (condom break, patch/ring/diaphragm dislodgment, IUD expulsion, missed pill, and late Depo injection) 2. used only in women not already pregnant 3. use of ECPills (ECPs) not indicated in women w/ known or suspected pregnancy -however no known evidence of harm to pt, her pregnancy, or fetus if unintentionally taken during pregnancy 4. can be used safely in women in whom continual estrogen might otherwise be contraindicated, such as women w/ hx of DVT, PE, MI, stroke, or migraines w/ aura
Newer formulation OCPs
1. shortened placebo length 2. extended cycles 3. continous cycles
Who is sterilization ideal for? (2)
1. stable monogamous relationships where no (additionaL) children wanted 2. also in women for wom pregnancy would be life-threatening (ie major cardiac issues)
other causes for hot flashes
1. thyroid disease 2. autoimmune disorders 3. carcinoid tumors 4. pheochromocytoma tumors 5. SERMs (tamoxifen/raloxifene, ospemifene) use
Ads/Disads of SPRMs in EC (in who is ulipristal contraindicated)
1. ulipristal contraindicated in women who are breast feeding or currently pregnant, given its antiprogestin efffects and potential to terminate an exisiting pregnancy 2. pregnancy test required before amdin of ulipristal 3. advtanges of its use include: 1-time dosing and relatively mild side effects disad 1. prescription only 2. use is controversial b/c potential use as abortifacient (although not approved for this) -in contrast to progestin-only or combined estrogen/progestin ECPs, because they do not terminate an existing preg nor cause teratogenic effects -for these resaons ulitpristal not widely prescribed when compared with other ECPs
Effectiveness of ECPs
1. when taken w/in 72 hrs of intercourse, FR of 0.2-3% 2. sooner taken, the more effective 3. risk of pregnancy reduced by 75-90% in women who have had unprotected intercourse during 2nd or 3rd week of their menstural cycles, when they are most likely ovulating
Follicular phase in more detail
1. withdrawal of estrogen and progesterone during luteal phase of prior cycle causes a gradual increase in FSH 2. FSH stimulates growth of approx 5-15 primordial ovarian follicles (initiating follicular phase again) 3. one becomes dominant follicle and matures until ovulation 4. dominant follicle produces estrogen that enhances follicular maturation and increases the production FSH and LH receptors in autocrine fashion
In who is copper T not acceptable form of EC?

Vitamin D intake
600 IU/day for most women and 800 IU/day for women >70 yrs routine screening for vitamin D def should be limited to pts w/ medical conditions or medication use placing them at high risk of vit D deficiency Vit D levels of 30 ng/dL were assoc w/ decreased risk of bone fracture
Extended therapy
>3-5 years for EPT and >7 yrs for ET may be appropriate for woemn w/ persistent symptoms who understand risks
Ads/Disads of Tubal ligation/occlusion
Ads 1. permanent effective contraception w/o continual expense, effort, or motivation mortality rate=4/100,000 women major risks=those assoc w/ surgery including risk of infection, hemorrhage, conversion to laparotomy, viscus injury, vascular damgage, and anesthesia complications 1. results in very low risk of preg, however when does occur increased risk of ectopic preg (1/15,000) however nearly 1000 maternal lives are saved b/c of sterilization during the period from the time of sterilization to end of woman's reproductive life
Diagnosis of Osteoporosis
Bone mineral density (BMD) screening -should begin at age 65 yrs for all women -postmenopausal women under age of 65 yrs should be screened if they have significant risk factors including hx of fragility fracture, weight <127 lbs , parent with history of hip fx, current smoking, alcoholism, or RA
Emergency IUD Insertion MOA
Copper T IUD (ParaGard) can be inserted in the uterine cavity within 120 hours (or 5 days) of unprotected intercourse as a form of EC. IUD functions primarily by eliciting a sterile inflammatory response within the uterus, making the environment unsuitable for fertilization
Menstrual cycle phases
Divided in two 14-day phases (changes in ovary) 1. follicular 2. luteal (changes in endometrium) 1. proliferative 2. secretory
What is ParaGard also approved for?
EC (emergency contraception) when placed w/in 72 hrs of unprotected intercourse or contraceptive failure
IUD Side Effects
Extremely safe in general 1. pain 2. bleeding 3. intrauterine and ectopic pregnancy 4. expulsion 5. perforation 6. infection
FSH levels during perimenopause
FSH level may vary greatly and are not required to diagnose menopause absence of menses for 1 yr w/ consistently elevated FSH levels >40 IU/L is considered diagnostic of menopausa FSH levels above 40 IU/L do not, however, correlate with when a woman will have the FMP Lab analysis looking for reliable and predictive marker for the FMP is ongoing
Nonhormonal Tx of Menopausal Symptoms
For women who are unable or unwilling to take MHT or who have completed short term ET or EPT
When pregnancy is desired afte rtubal ligation, what offers a greater likelihood?
IVF however, when multiple future pregnancies are desired, tuboplasty may be more economical alternative than multiple IVF cycles
What can Mirena be used to treat? Newer forms of IUD?
LNG-contained IUD so can be used to tx: 1. menorrhagia 2. dysmenorrhea 3. postmenopausal women receing ET the newer forms of LNG IUDs (Skyla, Liletta, and Kyleena) do not have specific indications other than contraception at this time
in who is DMPA not contraindicated, but what should be done?
NOT contraindicated in obese women, but weight monitoring should be used in women w/ increased risk for weight gain women who gain >10 lbs after 6 mo of use should consider another contraceptive
Implantatable Progesterone-Only Contraception MOA
Nexplanon 1. subdermal progestin implant 2. provides 3 yrs of uninterrupted contraceptive coverage 3. progestin = etonogesterol (same as NuvaRing) 4. 4cm x 2 mm, contains 68 mg etonogestrel, provides slow release of hormone over 3 years 5. radiopaque, size of matchstick 6. applicator facilitates placement in subdermal skin of inner side owman's upper arm 7. when approriate timing of placement is utilized, Nexplanaon effective 24 hrs after placement and has quick return to fertility once removed 8. acts by supressing ovulation, altering endometrium, thickening cervical mcus
Vaginal Hormonal Contraception MOA
NuvaRing hormone-releasing vaginal ring with brand name NuvaRing releases daily dose of 15 mcg of EE and 120 mcg of etonogestrel (active form of desogestrel) ring is placed in the vagina for 3 weeks (it is likely effective for 4 weeks), and is removed for 1 week to allow for withdrawal bleed hormone free period can be skipped to allow for ocntinous dosing typically for 3 months
OCP MOA
Oral contraceptive pills are composed progesterone alone or a combo of progesterone and estrogen over 150 million women worldwide (1/3 of sexually active US women) use OCPs place body in "psuedopregnancy state" by interfereing with the pulsatile release FSH and LH from the AP -this suppresses ovulation and prevent pregnancy from occuring -estrogen components of OCPs inhibits FSH secretion thereby suppressing formation of the dominant follicle -progestin suppresses LH secretion, thus preventing the LH surge and ovulation, also induces thin decidualized endometrium that is not receptive to implantation, while also thickening the cervical mucus making it less permeable to sperm bleeding that takes place during homrone-free interval is actually bleed due to withdrawal of homrone rather than menstrual period induced by endogenous hormone fluctation
PEPI Trial
Postmenopausal Estrogen/Progestin Interventions Trial
Progestin-Only OCP MOA
Progestin-only pills (POPs, Micronor, Nor-QD) deliver a small daily dose of progestin (.35 mg norethidrone) w/o any estrogen POPs have lower progestin doses than combination pills, thus nickname= minipills alsodiffer from traditional pills in that they are taken every day of cycle w/ no hormone-free days POPs bleived to: 1. thicken cervical mucus making it less permeable to sperms -decreases after 22 hours, so minipil must taken at same time each day other MOA include: 1. endometrial atrophy 2. ovulation suppression (50% of cycles)
Side Effects of Vasectomy
Rare and usually invovle slight bleeding, skin infection, and reactions to sutures or local anesthesia 50% of pts form antisperm antibodies after procedure however, there are no long-term side effects of vasectomy

Delayed puberty
absent or incomplete breast development by age of 12 years
growth spurt
acceleration in growth rate around age 9-10 yrs, leading to mean peak growth velokcity of about 9 cm/yr around age 12 yrs increased rate of growth is because of direct effect of sex steroids on epiphyseal growtha dn because of the increased pituitary GH secretion in response to sex steroids

Ectopic pregnancies and IUDs
b/c IUDs are so effective at preventing pregnancy, risk of ectopic is reduced in IUD user compared w/ that of non contraceptive users in rare event that a owman does become pregnant w/ IUD in place, however, the risk of ectopic pregnancy may be as high as 30-50% IUD is accetpable form of contraception for women w/ 1. prior hx of ectopic pregnancy 2. remote PID (none in past >3 mos) 3. hx of cervicitis 4. HIV

What should be done after use of Essure?
b/c tubal blockage is accomplished over time, pts current method of BC should be continued until Essure Confirmation Test performed 3 mos after procedure modified hysterosalpingogram (HSG) can confirm coil location and compelte tubal occlusion, whereas specialized transvaginal U/S can verify correct micro-insert location w/o confirming occlusion -most pts reassurbed by thsi confirmatory test, whereas others burdened by additional step to acheiving permanent sterilization -prior to procedure pt should understand it is essnetially irreversible
In who are the results of MHT most favorable? Who should it not be used in?
before age 60 yrs and w/in 10 yrs of menopause tx must be considered carefully, however, particularly in older women Should not be used for prevention of other chronic disease such as CVD, CHD, or dementia

ET associated w/ fewer invasive breast cancers after 7 years 6. EPT (but NOT ET) assoc. w/ higher rates of death from NSC lung cancer, but neither assoc. w/ incidence of luing cancer 7. increased dementia in women ages 65-79
Essure
both OR and OP practices that involve non-incisional hysteroscopic approaches Essure= soft, flexible, 4cm radiopopaque microinserts introduced into proximal (uterine) portions of fallopian tubes -outer spring coil made of nickel-titanium alloy and molds to the shape of fallopian tube to anchor and microinsert across utero-tubal jxn -inner coil contain spolyethylene terephthalate (PET) fibers that incite natural in-growth of tissue -over about 12 wks, sterilization accomplished as in-growth of tissue around coils results in occlusion of fallopian tubes -tubal ligation achieved by both space-filling outer coil and tissue in-growth elicited by PET fibers of inner coil

Side Effects of Tubal Sterilization
no side effects some women report: 1. pain 2. menstural disturabnce this was once called post-tubal ligation syndrome (discounted by lit) in most of these women, symptoms are due to discontinuation of homrone-containg contraceptives -> as result pts may experience heavier baseline menses and dysmenorrhea in rare, circumstances, malplacement of Essure coils has constributed to signif pain requiring subseq surgical coil removal,salpingectomy, or rarely, hysterectomy
What are IUDs NOT assoicated w/?
not assoc. w/ any increased risk of congenital abnormalities
adrenarche
occurs before any perceived phenotypic change with regeneration of the zona reticularis in the adrenal cortex and production of androgens and ultimately stimulates the apperance of pubic hair between ages 6-8 yrs when the adrenal gland begins regeneration of the zona reticularis this inner layer of the adrenal cortex is responsible for secretion of sex steroid hormones
effectiveness of Nexplanon
one of most highly effective reversible methods, failure rate only .5%
Hot flashes and night sweats
only FDA approved nonhormonal medication to treat VMS in menopausal women is paroxetine sulfate (Brisdelle 7.5 mg) -other SSRIs and SNRIs, including citalopram and venlafaxine, have shown efficacy -low doses of gabapentin or clinidine have also shown beneficial effects Cognitive behavior therapy -effective for hot flashes -behavioral changes (avoiding triggers, using fans, cooling sleep pillow, sweat-wicking sleepwear AE of SSRIs and SNRIs: sexual side effects, drowsiness, or nausea making pt education a critical component to sucess
pubarche
onset of growth of pubic hair usually occurs around age 11, often accompanied by growth of axillary hair usually follows thelarche, but a normal variant may occur with pubarche preceding thelarche, particularly in African American girls. Growth of pubic and axillary hair is likely secondary to increase in circulating andorgens
Effectiveness of SPRMs in EC
pregancny rate when prescribed w/in 120 hr window ~2%
EC works by
preventing pregnancy, not by disrupting implanted pregnancy EC thought to account for 40% decline in therapeutic abortions in past 10 yrs, while also decreasing the number of teen pregnancies
Tubal Sterilization MOA
prevents pregnancy by surgically occluding both fallopian tubes to prevent the ovum and pserm from uniting can be performed in immediate postpartum period (postpartum sterilization PPS) or outside postpartum period via laprascopic approach (laparoscopic tubal ligation LTL) or via hyteroscopic tubal occlusion (Essure)
POI
primary ovarian insufficiency (formerly premature ovarian failure) onset of spontaneous menopause >40 yrs, requires fiurther testing usually 1. idiopathic or 2. autoimmune if it occurs before age 30, chromosomal studies can be ordered to rule out genetic basis (eg mosaicism) approx 6% of women with POI are found to have premutations of FMR1 gene, and another 3% will have autoimmune or adrenal abnormalities
tx of endometrial hyperplasia
progesterone, NOT COCs (estrogen causes uterine growth)
Which formulation of oral EC is most effective?
progesterone-only formulations (Plan B) =most effective and fewer side effects thus single dose of LNG 1.5 mg (Plan B One Step, My Way, Next Choice One Dose) should be used as a first choice when available, rather than combo method
most common prepacked Plan B
progestin only -canbe taken as single 1.5 mg of LNG (Plan B One Step) or as two 0.75 mg doses taken 12 hrs apart (next Choice) regardless of regimen, first dose must be taken w/in 72 hrs of unprotected vaginal intercourse some additional efficacy if initiated w/in 120 hrs although not as high as within first 72 hrs

neoplastic complications of OCPs
rare effect of long-term oral contraceptive use on breast cancer has been studied w/ no conclusive findings
Effectiveness of Emergency IUD
reduces risk of preg by 99.8% therefore, only 1/100 become pregnancy after emergecy IUD insertion making it the most effective form of EC
Follicular phase
release of FSH from pituiary gland results in dev of primary ovarian follicle -produces estrogen (causes uterine lining to perforate)
Effectiveness of OCPs
remarkably effective in preventing pregnancy TFR=<1% failure for actual real-life usage is closer to 8% nausea, breakthrough bleeding, and the necessity of taking the pill every day are often cited as reasons for discontinuing the pill
Advantages of Essure
requires no general anesthesia or surgical incisions -when hysteroscopic tubal sterilization/occlusion performed, very little recuperative time needed -safe, more effective, hormone-free method of permanent birth control most commonly performed in office setting making it preferable option to surgical steriliation for all women, including obese women, women w/ prior abdominal surgeries or those at risk from anesthesia use
Women using DMPA for more than 2 years may experience
reversible decrease in bone mineralization similar to that seen in lactating women, due to decreas ein ovarian estradiol production thus, vit D, Ca, weight-bearing/strength exercise, smoking cessation should be encouraged

With exception of Essure, vasecomty is .....
safer, simpler, and more effective than female sterilization when pregnancies occur after vasectomy, many are due to ahving intercourse too soon afte rvasectomy rather than from recanalization of vas deferns
Side Effects of Emergency IUD
same as discussed in IUD section
SERMs and TSEC
selective estrogen receptor modulators tissue-specific estrogen complex
new formulations of combo pill
shorten the placebo time and cycle length by giving 24 days of homrone (Rather than 21) followed by a 4-day hormone-free interval so-called "24/regimens" result in shorter 3-4 days menstrual cycle for most user
Rates of ectopic preg after Essure?
signficiantly decreased compared with that of LTL pts may also benefit from reduction in risk of ovarian cancer reason for this unclear, but it is speculated that tubal ligation may limit the migration of carcinogens from the lower genital tract into peritoneal cavity
Vasectomy MOA
simple and safe option for perm sterilization involving ligation of vas deferens may be performed in provider's office under local anesthesia thru small incision in upper outer aspect of each scrotum no-scalpel technique: -both vasa are ligated thru a single midline incision that reduces the laready low rate of complications assoc.
What occurs after discontinuation of Depo-Provera
some women may experience significant delay in return of regular ovulation (range of 6-18 mo; avg of 10 mo) this is indepdent of # of injections but may be directly related to weight of pt within 18 mo however, fertility rates return to normal
Complementary and alternative therapies
soy, black cohosh, phytoestrogens, dong quai, evening primrose oil) have not been found to more effective than placebo in tx of VMS may have side effects and are not recommended
Current Indication for MHT
suitable option for women with bothersome symptoms of menopause, including vasomotor and GU symptoms (in absence of any contraindications)
What dosing method is reserved for heavy and prolonged bleeds?
tapering method - take four pills for 4 days, three pills for 3 days, and so on until pack is complete, then resume from beginning used for short time
Major limit of WHI trials is
that the particpants wer emuch older (avg age of 63 yrs) and had higher BMIs (avg BMI of 34), and the sample had a higher percentage of smokers than subjects in most studies -makes more difficultt o generalize
gonadarche
the activation of the hypothalamic-pituitary-gonadal axis, which involves pulsatile GnRH secretion stimulating the AP to produce LH and FSH, which in turn, trigger the ovary to produce estorgens indepdnent of adrenarche and begins around age 8 years, when pulsatile GnRH secretion from the hypothalamus is increased there is also a changing sensitivity of the neuroendocrine system to negative feedback by gonadal hormones. This leads to pulsatile secretion of LH and FSH from the AP initially these increases occur mostly during sleep and fail to lead to any phenotypic changes as a girl enters early puberty, the LH and FSH pulsatility lasts thruout the day, eventualyl leading to stimulation of the ovary and subsequent estrogen release this in turn, triggers the characteristic breast bud development associated w/ puberty positive feedback of estradiol also results in initiation of LH surge and ability to ovulate
Tubal occlusion w/ Filshie clip
the clip is applied to the mid-isthmic poriton of the tube about 2 cm from the cornua lower jaw of clip should be vissible thru mesosalpinx to ensure inclusion of entire circumference of tube
Contraindications for ECPs

thorugh small subumbilical incision using epidural or spinal anesthesia most commonly used method = modified Pomeroy tubal ligation (aka Parkland) laprascopically, there are # of methods for tubal occlusion, including: 1. bipolar fulguration 2. silastic banding w/ Falope rings 3. clipping w/ Hulka clips or Filshie clips
Risk of taking 2 OCPs/day
thromboembolic events used for short periods such as for EC and abnormal uterine bleeding
What has the Mirena IUD been found to do? Other LNG IUDs?
to decrease menorrhagia (90% less blood loss) and dysmenorrhea also as equally or more effective than oral progestins in treating: 1. endometriosis 2. benign endometrial hyperplasia 3. endometrial cancer protects from PID w/ lower rate of PID than found in women w/o -decreases # of surgeries (D&Cs, endometrial ablations, hysterectomies) needed for pelvic paina nd bleeding ~60% of women will experience amenorrhea while using MIrena IUD at 5 years -other LNG IUDs also reduce bleeding and dysmenorrhea in some capacity
persistent VMS
up to 25% of women will have persistent VMS, however, and other physiologic etiologies need to be ruled out highest reported incidence of VMS in AA, Causcasian, then Asian
Adolescent menstural cycle
usually irregular for first 1-2 yrs after menarche, reflecting anovulatory cycles on avg takes about 2 yrs after menarche before regular ovulartory cycles acheived (failure to achieve may = reproductive disorder)
success of reversal
varies from 41-84$ dependign on method used
How does vasectomy differ from female tubal ligations?
vasectomy is not immediately effective (unlike female tubal ligations) b/c sperm can remain viable in proximal collecting system after vasectomy, pts should use another form of contraception until azoospermia is confirmed by semed analysis (6-8 wks)
Pregnancy Rate w/ IUD use + what to do if intrauterine preg occurs?
very low, however, when pregnancy does occur, spontaneous abortion rate increased to 40-50% for women who become pregnant with an IUD in place given this, if intrauterine preg occurs while iud is in place, the device should be removed by gentle traction on the string

vuvlovaginal lubricants and moisturizers low-dose vaginal estrogen can have excellent local effects on vaginal and urethral atrophy with only minimal systemic absorption when used at low vaginal dosing, these estrogen sources do not require opposing progestin use in women with an intact uterus
When do menopause symptoms generally begin dissipate?
when estrogen and FSH levels stabilize about 2 years after the FMP
in who are OCPs contraindicated? What can be used for them?
women >35 yo who smoke 15 or more cigs/day these women often benefit from progesterone-only contraception (depo-provera, Nexplanon), hormonal and inert IUDs or permanent female or male sterilization
What should be done prior to performance of sterilzation?
women should be thoroughly counseled on the risk of regret, as well as alternatives such as vasectomy and LARCs
Who is ET reserved for?
women without intact uterus -use of unopposed estrogen is contraindicated in women with a uterus and requires addition of a suitable progestin to prevent increased incidence of EIN, endometrial hyperplasia, and endometrial cancer
