Q

inappropriate gonadotropin secretion mechanism

A

increase in GnRH –> increase in LH surge too soon –> no rise in FSH –> no dominant follicle –> no ovulation –> unopposed estrogen –> luteal phase never entered –> elevated levels of androgen –> PCOS

Q

insulin resistance with hyperinsulinemia mechanism

A

occurs in obese and non-obese women with potential defects in insulin receptor
potentially leads to PCOS

14
Q

last line treatment for ovulation induction in PCOS

A

in vitro fertilization (IVF) or in vitro maturation (IVM)

15
Q

cervical factors contributing to infertility

A

mucus becomes not receptive to sperm

16
Q

uterine factors contributing to infertility

A

anatomic factors (mass)
non-anatomic factors (subclinical inflammation and chronic endometriosis)

17
Q

tubal and peritoneal factors contributing to infertility

A

blocked fallopian tubes
interference with normal movement of the fallopian tubes
barrier between fallopian tube and the ovary
alteration of the pelvic environment

18
Q

ovulatory factors contributing to infertility

A

hypothalamic pituitary failure (abnormal response to or a decrease production GnRH)
dysfunction of hypothalamic pituitary ovarian axis
ovarian failure

19
Q

non-pharmacologic treatment for infertility

A

weight adjustment
avoid smoking, alcohol, caffeine, and illicit drugs
reduce stress
expectant management

20
Q

weight adjustment in infertility

A

gain weight if hypothalamic anovulation and BMI under 20
lose weight if high BMI and insulin resistance

21
Q

expectant management

A

watching of a patient’s condition but not giving treatment unless symptoms appear or change

22
Q

types of test/things to look out for in expectant management

A

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

23
pharmacological treatments for infertility
controlled ovarian hyperstimulation gonadotropins with or without IUI assisted reproductive techniques
24
controlled ovarian hyperstimulation treatment of infertility
aromatase inhibitor (letrozole) with or without IUI 1. monitor use with tamoxifen and methadone 2. avoid use with CYP2A6 substrate 3. dose 2.5mg to 10mg po x5d starting on day 3 of menses
25
gonadotropin with or without IUI treatment of infertility
develop multiple follicles by increasing FSH (combination of FSH and LH or either alone) IM or SQ injections requires careful monitoring usage of hCG (triggers ovulation with use of aromatase inhibitor afteR)
25
assisted reproductive techniques to treat infertility
intrauterine insemination (IUI) IVF intravaginal culture intracytoplasmic sperm injection (ICSI)
26
intrauterine insemination (IUI) to treat infertility
delivering washed sperm into uterine cavity via soft catheter less invasive used when younger than 40 yo less expensive -- cost 865$ per cycle
27
IVF to treat infertility
surgical retrieval of matured eggs from ovaries and fertilized in vitro, embryos transferred back to the uterus 3 to 5 days after fertilization for implantation success rate of 20 to 30% per cycle extremely expensive -- $8,151 per cycle or $11,000 to $15,000 per cycle with medication
28
intracytoplasmic sperm injection (ICSI) to treat infertility
single sperm injected into egg to achieve fertilization in conjunction with IVF procedures overcomes severe male factor infertility (sperm count) additional costs -- $1,544 per procedure
