Lecture 48/49 Flashcards
PCOS/Infertility -- Chen πππ
symptoms of PCOS
hyperandrogenism
menstrual disturbances
overweight or obese
hyperandrogenism symptoms of PCOS
hirsutism
acne
alopecia
menstrual disturbances symptoms of PCOS
amenorrhea
oligomenorrhea
anovulation
three proposed mechanism of PCOS
inappropriate gonadotropin secretion
insulin resistance with hyperinsulinemia
excessive androgen production
inappropriate gonadotropin secretion mechanism
increase in GnRH β> increase in LH surge too soon β> no rise in FSH β> no dominant follicle β> no ovulation β> unopposed estrogen β> luteal phase never entered β> elevated levels of androgen β> PCOS
insulin resistance with hyperinsulinemia mechanism
occurs in obese and non-obese women with potential defects in insulin receptor
potentially leads to PCOS
first line treatment of menstrual cycle irregularity in PCOS
COCs
second line treatment of menstrual cycle irregularity in PCOS
cyclic progestin therapy (medroxyprogesterone or micronized progesterone)
progestin-only OC
LNG IUD
Metformin
first line treatment of hirsutism/acne in PCOS
COCs
second line treatment of hirsutism/acne in PCOS
anti androgens β spironolactone, finasteride
third line treatment of hirsutism/acne in PCOS
topical vaniqa (eflornithine for facial hair only)
last line treatment of hirsutism/acne in PCOS
cosmetic treatment like bleaching, plucking, waxing, shaving, or laser
first line treatment for ovulation induction in PCOS
letrozole (aromatase inhibitor)
four main factors that contribute to female infertility
cervical (<10)
uterine (<10)
tubal and peritoneal (40)
ovulatory (40)
second line treatment for ovulation induction in PCOS
clomiphene and metformin
low dose gonadotropin therapy
laparoscopic ovarian drilling (ovarian diathermy)
last line treatment for ovulation induction in PCOS
in vitro fertilization (IVF) or in vitro maturation (IVM)
cervical factors contributing to infertility
mucus becomes not receptive to sperm
uterine factors contributing to infertility
anatomic factors (mass)
non-anatomic factors (subclinical inflammation and chronic endometriosis)
tubal and peritoneal factors contributing to infertility
blocked fallopian tubes
interference with normal movement of the fallopian tubes
barrier between fallopian tube and the ovary
alteration of the pelvic environment
ovulatory factors contributing to infertility
hypothalamic pituitary failure (abnormal response to or a decrease production GnRH)
dysfunction of hypothalamic pituitary ovarian axis
ovarian failure
non-pharmacologic treatment for infertility
weight adjustment
avoid smoking, alcohol, caffeine, and illicit drugs
reduce stress
expectant management
weight adjustment in infertility
gain weight if hypothalamic anovulation and BMI under 20
lose weight if high BMI and insulin resistance
expectant management
watching of a patientβs condition but not giving treatment unless symptoms appear or change
types of test/things to look out for in expectant management
urine ovulation predictor kits
timed intercourse
change in cervical mucus
basal body temperature monitoring
vaginal monitoring
mid-luteal phase progesterone levels
FSH levels on day 3 of cycle
