Common menstrual disorders Flashcards
When is menarche usually? menstrual period
around 13 years old in the United States.
What happens during mensration in all the hormones?
↓ Estrogen(E2) & Progesterone (P4)- stimulates hypothalamus (GnRh)
↑ GnRH stimulates follicle-stimulating hormone (FSH)
↑ FSH stimulates development of the ovarian follicles= ↑ovarian production of E2
Slight midcycle ↓ E2 triggers GnRH to stimulate the anterior pit to secrete luteinizing hormone (LH)
A Surge of LH and small ↑ E2 stimulates ovulation. If fertilization doesn’t occur- E2 & P4 decrease and the corpus luteum regresses
What happens in the follicular phase of the ovarian cycle?
- Follicular phase
- Before ovulation FSH & E2 cause development of 1-30 follicles
- LH causes 1 oocyte to mature and is released (usually around day 14)
What happens in the follicular phase of the ovarian cycle?
Luteal Phase
- Begins after ovulation- ends with menstruation
- Corpus luteum secretes E2/P4= peak day 8
- Corpus luteum regresses without conception
What’s the MENSTRUAL PHASE of the endometrial cycle?
The shedding of the functional endometrium
Whats the PROLIFERATIVE PHASE of the endometrial cycle?
E2 causes- Rapid endometrial growth
What’s the SECRETORY PHASE of the endometrial cycle?
P4 causes endometrium to thicken- ↑ blood
What’s the ISCHEMIC PHASE of the endometrial cycle?
Spasm and necrosis of the functional layer of the endometriuum
The surge of which hormone causes Which hormone is responsible for the maturation and release of an oocyte at midcycle?
LH
