64
anovulatory amenorrhea
alteration in menses; irregularity; unpredictable NO mittelschmerz or PMS caused by: PCOS
65
common cause of infertility
chronic anovulation
66
amenorrhea: disorder of hypothalamic/CNS causes
lifestyle! ## Footnote excessive exercise, issues a/s with excess exercise (catechol estrogens are produced and endorphins, which inhibit GnRH, LH, FSH) Dramatic life events Grieving process = amenorrhea Anorexia Hypothalamic lesions, tuberculosis, sarcoid, and encephalitis = dec secretion of GNRH and reduced levels of FSH and estrogen
67
what meds / conditions can cause amenorrhea
meds that affect prolactin levels: antihypertensives, psychotropics, H2 blockers, oral contraceptives chronic dz: diabetes, crohns, CF, celiac dz
68
amenorrhea: disorders of anterior pituitary causes
from hyperprolactinema; a prolactinoma (secretes prolactin) tumor! most common cause hypothyroidism can lead to hyperprolactinemia increasing dopamine from hypothalamus inhibits GnRH = inhibits steroidogenesis
69
amenorrhea work up
1. Rule out pregnancy and peri-menopause 2. overall health: malnutrition, Exercise, recent weight changes, disorders of eating (anorexia, crash dieting, rapid weight loss), Obesity Meds, herbs, Emotional state, chronic illness 3. Physical exam, BMI, Gynecological and breast examination (galactorrhea) 4. Assess TSH and prolactin levels (hyperprolactinemia common with anovulation) 5. Administer provera challenge test 6. Assess FSH & LH levels ovarian failure dx if FSH high and low estrogen
70
provera challenge test
7-10 day course of provera making high levels of progestin then stop taking that to create withdrawal bleeding Positive if get period = it's not due to obstruction & has estrogen but not ovulating/anovulation Negative if no period = adhesions/ashermans or not enough estrogen making endometrium not thick enough If fails, give exogenous estrogen to determine if that’s part of problem If responds, we know its limited endogenous estrogen or inadequate estrogen Draw gonadotropin levels
71
ovarian amenorrhea most common cause
ovarian fxn abnormalitiies ovary resistant to FSH or LH stimulation (PCSO) or lacks egg to ovulate
72
hypothalamic or pituitary amenorrhea r/t to
deficiency of FSH and LH
73
assess what for heavy menstrual bleeding
duration, color, presence of clots, character of bleeding look for anemia
74
heavy bleeding assessment
1. r/o pregnancy 2. Manual exam 3. Pelvic exam Masses (ovarian, uterine) = pap smear CBC, TSH, liver fxn, coagulation r/o infections with cervical cultures, endometrial bx if indicated 5. Pelvic sonogram = assess fibroids, polyps, measure endometrial stripe During follicular phase, endometrial thickness is 1-2mm During preovulation, layer 3-5 mm Endometrial stripe \> 5 mm = suspicious! Eval
75
heavy bleeding tx single epsidoe vs chronic/cyclic
single is prob due to pregnancy or infection chronic/cyclic: manage with IUD, **monophasic** OCP, patch/ring, Progestin (limits growth), depo, GnRH agonist (Lupron), NSAIDs, Danocrine (Danazol) but weight gain non pharm: acupuncture, chinese med, herbs, aromatherapy
76
acute vaginal bleeding tx
estrogen and progestern 3x the dose but NAUSEAAAAA
77
metrorrhagia etiology
Possibly of preg Threatened spontaneous abortion Ectopic pregnancy Gestational trophoblastic neoplasm Mid-cycle spotting might signal ovulatory bleeding with heavy bleeding. An STI can be a source of the problem, including cervicitis, vaginitis, or pelvic inflammatory disease. Trauma related to sexual activity or abuse Need sexual history and extensive assessment regarding interpartner violence or assault.
78
metrorrhagia tx
if from OC = change/review dosing, change if not OC = stop OC to allow healthy buildup progesterone therapy Nuvaring, patch, progesterone IUD
79
primary dysmenorrhea
begins **6-12 months** after menses (menarche) d/t **increased prostaglandin production = uterine contraction** (use NSAID) ischemic pain **recurrent sx's with each cycle and stops after end of period** NOT from hx of anxiety/depression/psychosomatic dz
80
secondary dysmenorrhea causes
#1 cause: endometriosis adenomyosis (2nd common) fibroids, polyps, cysts, cancer, PIDS: STI's, pelvic floor weakness, non GYN issues: IBS, interstitial cystitis or UTI
81
secondary dysmenorrhea assessment
GYN, obstretic, sexual hx physical exam US - pelvic pathology r/o STI if sus endometrial cancer, collect bx if from IUD = remove and alt methods
82
when can secondary dysmenorrhea happen? is it related to prostaglandins?
before, during, or after period NOT caused by prostaglandins
83
Primary dysmenorrhea Management: Pharmacological vs Non Pharm
pharm: first line is NSAIDS (start 2-3d before menses + 2-3 d ibuprofen 400-800 mg q 6 hrs or naproxen 500 mg onset) combined hormonal contraceptives progestin only contraceptives (LNG IUD, Nexplanon), Depo BUT not immediate results (takes 3-12 mo) non pharm: heat, no smoking/sugar, soda, exercise, belladonnna/camilla (herbal), acupuncture/relaxation aromatherapy
84
premenstrual disorder (PMD) sx's appear ONLY during what phase
luteal phase (7 days or less before menses and RESOLVES with menses) day 4-13 moderate sx's = PMS severe sx's = PMDD
85
PMDD sx's in majority of cycles and have at least 1 of these sx's:
_1 or more_: emotional lability, anger, feelings of hopelessness, anxious _1 or +, total 5 or +:_ poor concentration , appetite changes, decreased interest in activities, fatigue, overwhelmed, breast tenderness, bloating , weight gain, aching joints, insomnia or hypersomnia
86
how is PMDD thought to happen
neurologic hypersensitivity to normal hormone fluctations NOT depression, NOT hormonoe changes
87
best tx for PMDD
stabilize hormones suppressing ovulation with hormonal contraceptives, especially drospirenone, or Yasmine and Angeliq. or SSRI antidepressants
88
PMDD management pharm & nonpharm
stabilize hormones; suppress ovulation = COC **drospirenone** SSRI #1 if sx is mostly emotional/PMS and taken only during luteal phase/day 14 [fluxoetine, sertraline, paroxetine] anxiolytic last resort (Buspar, Ativan, lorazepam) nonpharm: healthy, exercise, stress, smoking, sleep herbal: vitex agnus castus, curcumin (tumeric), Calcium supplements 500 mg, acupuncture, acupressure
89

91
TSS involves what organs
GI, MSK, mucus membranes, hepatic, hematologic, CNS
92
TSS Dx and tx DO NOT WHAT
SEND TO ER! culture, IV hydration, infectious dz, broad spectrum antibiotics, corticosteroids, immune globulin, supportive therapy DO NOT RESUME TAMPON USE/MENSTRUAL CUP/BARRIER CONTRACEPTIVES LIKE DIAPHRAGM/CAP/SPONGE
93
what is the most common org for TSS
staph aureus
94
what is the leading cause of infertility
PCOS
95
PCOS patho
ovaries make excess male hormone, either excess LH or excess insulin = stimulate androgen production in ovaries androgen precursor to estrogen = hyperplasia risk 'string of pearls' bc no LH surge insulin resistance could be leading cause
96
PCOS risks
anovulation/infertility obesity hirsutism CVD endometrial cancer DM 2
97
diagnosis criteria for PCOS
according to PCOS consensus group: need 2 of 3: oligo/anovulation, clinical/biochemical signs of hyperandrogenism, polycystic ovaries according to androgen excess and PCOS society: hyperandrogenism, ovarian dysfxn (anovulation and/or cysts), exclusion of aother androgen excess
98
PCOS diagnosis
PE: BMI, trunical obesity, virilization, moon face, buffalo hump, alopecia, amenorrhea, hirt, acan nigri thyroid exam breast: galactorrhea pelvic: bimanual exam screen for depreesion
99
screen PCOS for
if have menstrual dyxfunction + hyperandrogenisms, screen: Pregnancy—urine hCG Hypothyroidism—TSH Hyperprolactinemia—prolactin level Glucose intolerance—OGTT Dyslipidemia—lipid profile
100
R/O other causes of hyperandrogenism with PCOS such as
Androgen-secreting tumor Adrenal gland tumor Adult-onset non-classical congenital adrenal hyperplasia CAH Cushing’s syndrome
101
PCOS management
determine if wanna get preggos, life style mods (diet, sat fat, fiber), exercise COC! suppress enlarged ovaries and inhibit LH/androgen secretion = helps normalize ovary function, protect endometrium, raises sex hrmone binding globuin = binds to testosterone (helps with hirtsusism) Progesterone, Levonorgestrel (LNg) - Mirena progestin only pills DMPA (depo provera) or implant (DONT give if want preg soon) if no contraception, medroxyprogesterone acetate QD x 14 days
102
PCOS tx for hirsutism
antiandrogens: spironolactone (Aldactone) finasteride (Propecia, Proscar)
103
PCOS managing metabolic abnormalities
metformin and oral antihyperglycemics inhibits glucose production, decrease androgen lvls with PCOS (no weight loss) dec insulin, BP, LDL cholesterol regulate menses, induce ovulation with clomiphene
104
PCOS f/u
tx diabetes, dyslipidemia, and hypertension ## Footnote Smoking cessation Repeat lipid profiles every two years HgA1c screening for diabetes annually
105
birth control
limitation of children conceived or via specific methods of contraceptives
106
contraception
preventing pregnancy via contraceptive methods
107
efficacy
likelihood conception occurs when evaluating birth control methods "true method failure" from "perfect use"
108
effectiveness
measuring success of method preventing pregnancy when used user error; what's really happening
109
open adoption
birth mother + adoptive family know each other
110
closed adoption
birth records closed/sealed, all identities concealed
111
semi open adoption
identifying info is shared b/t parties communicaiton occurs at a pre-arranged intervals via agency or attorney
112
medication abortion most often used up to? surgical?
10 weeks mifepristone + misoprostol or methotrexate products of conception passes 2-4 hrs after misoprostol or 24 hrs later surgerical: aspiration/manual vacuum \< 14 weeks, D&C after 14 wks, D&Evacuation after 14-15 wks+
113
Mifepristone indication and MOA
**Mifepristone** blocks progesterone receptor sites (require for normal implantation) & prevents fertilization can be used up to 10 weeks/70 days prostaglandin analog used with misoprostol 95-98% effective
114
methotrexate MOA / indic
inhibits enzymes required for DNA synthesis and stops normal mitosis of rapidly dividing cells 60-84% effective takes up to 2 wks for expuslion (undesirable)
115
coitus interruptus
withdrawal method 12/100 get pregnant; no STI protection pre-ejac fluid may have sperm
116
lactational amenorrhea (LAM) criteria
using beginning of postpartum period as contraception high levels of prolactin from BF inhibits gonadotropin releasinghormone = sets off HPO axis = prevents ovulatin criteria: exclusive/near exc BF (4 hrs max b/t feedings, and 6 hrs max at night), amenorrhea, infant \< 6 months PUMPING reduce effectiveness
117
Fertility Awareness Based on Methods
Identify the fertile period during the menstrual cycle + abstinence and/or a barrier method to prevent conception during the time when the risk of pregnancy is at its highest fertile period: 5 days before ovulation until 1 day after ovulation = need back up method during this time least effective contraception
118
contranindications to FABM
anything that interrupts cycles, birth, menarche, BF, intermenstrual bleeding, infxns
119
calendar method
count/record 6-12 months to find longest and shortest cycle. Then find the 1st and last fertile days expected in her routine or menstrual cycle. subtract 18 from shortest cycle and 11 from longest cycle
119
Calendar Method: Standard Days Method
MUST have cycles of 26-32 day cycle barrier contr days 8 - 19 circle beads (32 beads)
120
Calendar Method: Billings Ovulation Method
changes in cervical mucus to determine the fertile window. Pt observes the sensation of moisture around the vulva and the presence of mucus throughout the day and records observations daily. Abstinence first cycle to record! fertile window: when observe vulva wetness slick, slippery up to 4 days estrogen causes spinnbarkeit (mucus increases, clear, stretchy egg white) before ovulation
121
Calendar method: Two-day method
Did I note secretions today? And did I note secretions yesterday? If yes, NO SEX Typically, this results in 10 to 14 days of abstinence during her menstrual cycle. check daily for secretions
122
Basal body temperature (BBT) Method
Measures basal body temperature daily BEFORE GETTING OUT OF BED progesterone (corpus luteum) causes rise in temp = ovulation rise of 0.4F or more = ovulation fertile days: sharp temp rise and continue for 3 days until 5 day progressive increase
123
symptothermal method
BBtemp AND cervical mucus/observations self-examines the cervix, os is dilated slightly and cervix is higher in the vagina and softer. After ovulation, the cervix becomes more firm and lower in the vaginal canal and closed.
124
pros and cons to FAB
_Pros:_ Min cost User control Culture acceptance _Cons_: Abstinence or barrier BC needed (10-12 days monthly if not longer) Complicated No protection from STI
125
male condoms
Natural rubber latex Made of polyurethane = synthetic material for latex allergy. Prevent STIs Latex condoms are effective in preventing HIV and STI transmission (Non latex = not as effective) 18% will have unintended pregnancy. condom failures = breakage or slippage during intercourse or while removing the condom.
126
female condom
2 flexible rings; larger ring remains outside of the vagina and covers the introitus. 1 size only Can use lubricants and spermicides In for up to 8 hours before sex but must be in place before the penis enters the vagina Effectiveness: 79% during the 1st year of typical use.
127
Spermicidal agents with condoms agent? don't what?
chemical agents that are available as creams, aerosol, foam, supposed, gels, and tablets, vaginal film and sponges = kill sperm. Agent: **nonoxynol-9 (N-9**): surfactant that destroys the sperm cell membrane. The inert basin which the spermicide is compounded acts as a physical barrier to the cervical os. Don’t use for HIV protection !!! actually causes irritation and can cause HIV Don’t put in rectum = micro tears Don’t lube condom with N-9
128
using spermacide alone is
MOST ineffective contraceptive methods, with failure rates as high as 28%.
129
Sponge
Polyurethane with spermicide When moistened, releases 125-150 mg N-9 over 24 hrs Leaves in at least 6 hours after sex Irritation more common than diaphragm bc higher amt of N-9
130
toxic shock syndrome a/s with what BC and sx's of TSS
sponge ## Footnote an immunological, potentially fatal septic reaction to toxins from Staph aureus and Strep pyogenes. involves recent childbirth, leaving the device in place longer than 24 hours, or difficulty removing or fragmenting the sponge. presents as 2-3 day syndrome of mild symptoms including low backache or body aches, chills, and malaise. Sx worsen and rapidly progress to include fever higher than 101.4 or 38C. diffuse macular erythematous rash and hypotension occurs. teach to **remove the device within 24 hour**s of its insertion to avoid the risk of TSS
131
diaphragm and cervical cap both need what
spermacide to maximize eff!
132
diaphragm
Used with spermicidal gel or cream that's spread around the rim and inside the dome for maximum effectiveness. ## Footnote **needs fitting/various sizes** Inserted for up to 6 hours before intercourse and should remain in place in the vagina at least 6 hours after intercourse, but no longer than 24 hours because TSS If have sex again w/in the 6 hr window, add more gel, DON’T take the diaphragm out if PP, wait 6 weeks
133
diaphragm SE's
UTI due to pressure on the bladder or change in vaginal flora related to spermicide. Local irritation from an improperly fitting diaphragm may result in abrasions of the vaginal wall. potential for latex allergy. TSS if leave in \> 24 hrs Need to be refitted if the woman experiences weight gain, more than 15 pounds, or has had a 2nd trimester abortion or a vaginal birth within the past 6 weeks.
134
cervical cap
Dome-shaped cervical silicone cap that has suctionUsed with spermicide applied inside the dome and around the brim. FemCap 3 sizes: 22 mm for a nulligravida, 26 mm for a nullipara, and 30 millimeters for full term vaginal delivery Inserted up to 42-48 hours prior to intercourse and in place for at least 6 hours after intercourse 77% eff
135
what are some serious side effects with CHC
ACHES abdominal pain (hepatic mass/tenderness) chest pain (cough, SOB) headache (migraines) eye problems (visual changes/loss of vision/speech) severe leg pain (DVT, hot leg/edema leg)
136
other side effects CHC
Breast Tenderness Nausea h/a Altered bleeding pattern – spotting, breakthrough bleeding (not taking pill same day / time), increase/decrease bleeding, amenorrhea Mood Alteration – Mood swings and depression Libido changes Skin Changes and acne Acne gets worse before it gets better
137
health benefits of CHC; reduces risk of:
Reduce risk of: Endometrial cancer Ovarian Cancer Colon cancer Reduce anemia and blood loss with menses May reduce PMS/PMDD Reduce PID Fewer ectopic pregnancies Reduce benign breast conditions /Fibrocystic breast May reduce ovarian cysts Less dysmenorrhea Some improve acne and hirsutism Improve BMD
138
Long-Acting Reversible Contraceptives, or LARCs
IUDs, implant

150
Intravaginal Contraceptives the Ring
flexible, vinyl ring about 4 mm thick and 54 mm in diameter Body heat activated ; NOT A BARRIER METHOD Not systematically absorbed inhibits ovulation through suppressing the gonadotropins in the HPO access. alters cervical mucus, and the endometrial lining 91% effective keep in fridge x 4 months last 21 days and then, it's removed for seven days, to induce a withdrawal bleed. if out \> 3 hours= decrease in effectiveness
151
Progestin only pill (mini pill)
for those that are contraindicated using estrogen or lactating pts *only* thickens cervical mucus which happens 2-4 hrs after taking pill and lasts 22 hrs if **3 hrs late** taking pill, use back up BC x 2 days (strict schedule)
152
Depomedroxyprogesterone DMPA MOA
derivative of progesterone inhibit HPO axis; thickens cervical mucus, endometrial atrophy = less likely implantation shot every 13 weeks; suppresses ovulation q 14 weeks shot anytime as long as not preg don't massage site!!!! dec efff
153
side effects of depo
menstrual changes migraine with aura = STOP report h/a's weight gain common vag dryness delayed feritity **BBW: bone density loss (take Ca + Vit D suppls)**
154
DMPA benefits and pt education
_Benefits_: Reduces seizures Not affected by most meds Reduction in sickle cell risks Less menorrhagia and dysmenorrhea Decrease in eptopci preg, PID and endometriosis _Educate_: BMD loss, changes in bleeding pattern then amennorhea after 12 months Need ca vit D and weight bearing exercises DO NOT ORDER DEXA / BMD testing in young women if d/c, ovulation comes back 15-49 weeks after last injection weight management (weight gain)
155
MEC for DMPA
3 BBW density d/t supp gonadotropin secretion suppressing ovarian estradiol production but reversible
156
Nexplanon Implant
MOST effective contraception progesin analog x 7 yrs start after 6 wks PP or during first 7 days of period or termination barium sulfate = see on xray once take out, return to fertilty 6 weeks
157
implant SE
#1 unscheduled bleeding mood changes Weight gain Acne Breast tenderness Bruising /irritation at insertion site Small ovarian cysts Migration Infection at insertion site Difficult removal Damage to nerves and/or blood vessels Scarring
158
IUD
Liletta, Mirena, Skyla, Kyleena continuous release of levonorgesterl = absorbed locally by endometrium = changing mucus viscosity & diminished dev of endometrium NOT systmically absorbed insert any day but prefer during period (os more openand blood as lube) can be placed after birth but caution of explusion, up to 4-8 wks PP (give nonsteroids 30 mins prior), misoprostol (cervical ripening) if cramping
159
do IUD's cause ectopic pregnancy
NO. but if ferti with IUD, greater risk of ectopic implantation but risk of this still lower than no IUD and ectopic
160
if can't feel IUD strings on speculum...
1: r/o pregnancy uterus perforation strings thru uterine wall spontaneous expulsion strings cut short andmigrate up cervix (can retract string and pull back out)
161
pains reported to provided using IUD
P.A.I.N.S. period - irregular, late or spotting Abdominal pain or dyspareunia Infection or abn vag discharge Not feeling well, flu, chills strings missing
162
Copper IUD Paraguard MOA
NONhormonal; copper ions paralyze sperm and decrease motility Foreign body effect toxic to sperm and ova Local inflammatory response: creates spermicidal environment barium = x ray = shows
163
Copper IUD not good for
heavy menstrual bleeding (better using levonorgestrel IUD) or copper allergy worsens anemia, inc dysmenorrhea, and blood loss
164
Yuzpe method
Take 4-5 pills x 2, 12 hours apart high doses of estrogen and progestin, combined oral contraceptive pills in a single dose = inhibit ovulation Preg rate 2% to 3% LOTS of nausea and vomiting, headache, breast tenderness, irregular bleeding, or spotting = unfav
165
Copper IUD/Paraguard as EC
insert w/in 120 hrs/5 days after unprotected sex **most effective EC AND in obese women and ongoing contraception** (0.1%) alters tubal transport. It's toxic to the ovum and incapacitates sperm so that fertilization is prevented. inhospitable uterine environment, preventing implantation.
166
which IUD NOT effective for emergency contraception?
The levonorgestrel-releasing IUDs, like the Mirena, the LILETTA, the Skyla, and the Kyleena are NOT effective for emergency contraception.
167
female sterilization/ tubal ligation
done after vaginal delivery, C-section, uncomplicated first-trimester abortion, or independent of pregnancy, or whenever The fallopian tubes are surgically cut and ligated with or without a section of the tube being removed = salpingectomy May be mechanically blocked using clips or rings or coagulated electronically. blocked by a reaction induced by chemicals or micro-inserts. \>99% effective in preventing pregnancy. failure rate is about 0.5% in the first 12 months.
168
tubal ligation pros and cons
pros: decrease ovarian cancer and PID cons: high risk of ectopic preg won't rec if unsure of future, unlikely to get preventative health services, not wear condoms -\> STI, regrets
169
female transcervical sterilization
Essure insert into fallopian tubes new growth of tissue into a surrounding insert = forms scar tissue and occludes the tube. Need follow-up hysterosalpingogram, or HSG, to ensure occlusion has occurred about 3 months following the procedure. \*\*Taken off market in 2018 NO allergy nickels
170
male sterilization
vasecetomy The procedure involves cutting or occluding both of the vas deferens so that sperm can no longer traverse into the seminal fluid. uses ligation, cautery, or excision of a segment, and then application of clips.
171
no-scalpel technique
where the scrotum is pierced, and the vas deferens are then exposed and occluded through this small opening. no stitches and results in less bleeding, quicker recovery time, less issues with hematomas, infection, and pain. no difference in effectiveness between the no-scalpel technique and traditional conventional vasectomy.
172
Male sterilization counseling
NOT immediately effective. Sperm continually is produced and transported, so some sperm will continue to be present distal to the site of the procedure. Take between 15 and 20 ejaculations to clear all the sperm; wait 3 months. The failure rate is \< 1%, similar to the female sterilization; some post-operative discomfort; infection; scrotal hematomas are possible.
