Menstruation Flashcards
Menarche comes after _______ + _______
Menarche comes after thelarche (boobs) + pubarche (pubs)
Normal Ranges for Menstruation
- Start age
- Duration
- Blood loss: < ___ mL
- Cycle length
Normal Ranges for Menstruation
- Start age = 11-13
- Duration = 3-7 days
- Blood loss: < 80 mL
- Cycle length =21-35 days
first phase of the menstrual cycle
- whats it called (2)
- what days/events mark the beginning/end
First phase of menstrual cycle
- Called the follicular/proliferative phase
- Day 1 (menses) - LH surge (usu day 14)
What hormones dominate the follicular/proliferative phase
Follicular/proliferative phase dominated by FSH and estrogen
What hormone causes the primary/dominant follicle to be selected and produce estrogen
FSH –> primary/dominant follicle selected –> domin follicle produces estrogen
What is the role of estrogen w/ the endometrium
Estrogen –> endometrial lining to proliferate
What cycle day does LH surge usually occur and what does it cause
LH surge = day 14
- causes ovulation to occur
second phase of the menstrual cycle
- what is the name of it (2)
- what hormone dominates it
second phase of the menstrual cycle
- Luteal/Proliferative phase
- dominated by progesterone
Progesterone
- What secretes itprogesterone
- what is the role of it w/ endometrium
Progesterone
- secreted by corpus luteum
- maintains the endometrium/preps for implantation of ovum
If the ovum is not fertilized in 24 hrs what happens to the corpus luteum, progesterone, and endometrium
If the ovum is not fertilized in 24 hrs –> corpeus luteum degenerates –> decr progesterone levels –> slough the endometrium –> menstruation

- how to determine if Gonadal agenesis vs Turners
Primary Amenorrhea: Ovarian Failure
- decr estradiol –> incr LH and FSH
- (+) uterus, (-) breasts
- Gonadal agenesis = 46XX, Turner’s = 45XO
note: decr estradiol –> no breasts

No breasts but uterus present, determine if hypothal or ovary problem –> LABS
Ovarian failure –> decr estradiol, incr LH + FSH
Hypothal prob –> ALL labs decr (GnRH, LH, FSH)
(+) breasts, (-) uterus: Outflow Tract Abn… Mullerian Agenesis vs Androgen Insensitivity
