2 - Reproductive Physiology Flashcards
Heavy menses occurring in the context of ovulatory cycles with no other etiology is most likely caused by what?
- Endometrial pathology
* diagnoses of exclusion
What is the difference between menorrhagia and metrorrhagia?
- menorrhagia = excessive flow/duration
- metrorrhagia = irregular intervals
If a childbearing age patient presents with acute abnormal bleeding they need to be ruled out for what?
- ectopic pregnancy
Ovulation follows the LH surge by how many hours?
24-36 hr
A surge in this hormone causes oocyte in the dominant follicle to complete the first meiotic division (ovulation).
- Luteinizing hormone (LH)
What non surgical treatment option for fibroids is available for patients of non child-bearing age?
- uterine artery embolization
Why can’t you diagnose PCOS within 2 years of menarche in adolescents?
- menstrual irregularities during adolescents are common and cycles are frequently anovulatory
A peak in this hormone leads to the LH surge causing ovulation.
- Estradiol (E2)
What is the ultrasound diagnostic criteria for PCOS?
- > 12 follicles 2-9mm in diameter
- ovarian volume > 10 ml
*need only 1 ovary for diagnosis
Anovulation is defined as an absence of bleeding for greater than how many months?
2 months
What is the medical treatment for hyperprolactinemia?
- dopamine agonists (e.g. bromocriptine, cabergoline)
Which of the following is the most common location for fibroids?
a. subserosal (in serosa)
b. intramural (within uterine wall)
c. submucosal (in endometrial cavity)
b. intramural
What is on the differential for abnormal menstrual bleeding? (hint: PALM-COEIN)
- Polyp
- Adenomyosis
- Leiomyoma
- Malignancy
- Coagulopathy
- Ovulatory Dysfx
- Endometrial
- Iatrogenic
- Not yet classified
What type of hyperplasia has the highest risk of malignant transformation?
a. simple
b. complex
c. atypical
atypical
For adenomyosis:
- what is the main symptom?
- what is the main diagnostic method?
- what is the main treatment?
- pelvic pain
- biopsy
- go through menopause or hysterectomy
What hormone induces the production of ovarian androgens and progesterone?
- Luteinizing hormone (LH)
What test is used to diagnose diabetes in patients with PCOS? What do the results mean?
- oral glucose tolerance test (75 gm)
- <140 = negative
- 140-199 = intolerant
- > 200 = diabetic
How is estrogen breakthrough bleeding treated?
- give progesterone
What time of day do you want to check prolactin levels?
- early morning
