Infertility and ART Flashcards
Causes of female factor infertility in descending order?
1) Ovulatory disorders
2) Fallopian tube abnormalities (including adhesions)
3) Endometriosis
Ovulatory disorders
1) Hypogonadotrophic hypogonadal anovulation
2) Normogonadotropic normoestrogenic anovulation
3) Hypergonadotropic hypoestrogenic anovulation
4) Hyperprolactinemic anovulation
1) Hypothalamic amenorrhea
2) PCOS
3) Premature ovarian failure, advanced maternal age
Most common ovulatory disorders leading to infertility?
PCOS and advanced maternal age
What happens with oocytes after aging?
Accelerated loss after mid-30s. Decline in quantity and quality.
The problems with conception in AMA are NOT with her body, it’s with her eggs. She could easily carry a donor egg pregnancy!
Mechanism of PCOS?
Genetics affecting the regulation of gonadotropin, androgen, or insulin secretion and action.
Hyperandrogenism leads to disruption of the HPGA axis and leads to chronic anovulation.
How does endometriosis cause adhesions?
It can invade local tissues thus causing severe inflammation and adhesions
How could LEEP, mechanical dilations, etc. cause problems with fertility?
Can result in stenosis and destruction of the endocervical epithelium, leading to inadequate mucous production so sperm then have a hard time making it in.
Luteal phase defect?
Could result in inadequate production of progesterone by corpus luteum
How can you test for ovulatory factor infertility?
Tracking menstrual cycle, measuring basal body temperature, monitoring cervical mucus, measuring the mid-luteal progesterone
What is the test to detect decreased ovarian reserve?
Clomiphine citrate challenge test (CCCT)- give it on days 5-9 of menstrual cycle, measure FSH level on days 3 and 10.
Day 3 FSH should be low (<10mIU/mL) bc a woman with good ovarian reserve will make enough ovarian hormones early in menstrual cycle to INHIBIT FSH and keep it LOW.
Even small elevations in FSH levels correlate with decreased ovarian reserve
Newer battery of tests instead of CCCT?
Basal FSH/estradiol testing
Antral follicle count
Anti-Mullerian hormone assay
Day 3 estradiol should be 0.5 ng/mL) when the primordial follicle pool is good.
Use of saline sonohysterogram?
Complements u/s for better visualization of uterine cavity.
PCOS treatment?
weight loss, metformin
OI with clomid or letrozole
Improving fertility in endometriosis?
You can’t. You can try cutting through the adhesions and endometrial implants…
Improving fertility in primary ovarian insufficiency?
You can’t because there aren’t eggs to work with
