Female Repro Flashcards
1 oocyte makes how many mature egg cells
1
how long does the process of a follicle maturing to ovulation take
6-9 months
how big is a mature follicle
> 17mm
structure of a follicle
theca cells surround the oocyte and antrum filled with fluid
what is left when the egg leaves the follicle
it turns into corpus luteum
if pregnancy does not occur what happens to corpus luteum
it becomes corpus albicans
where is GnRH released from
the hypothalamus
action of GnRH
stimulate LH and FSH secretion from anterior pituitary
action of FSH
stimulate follicular development
action of LH
maintain the dominant follicle , induce maturation and ovulation and stimulate corpus luteum
where are granulosa cells
in the follicle around the oocyte
secretion of granulosa cells
when stimulated by FSH they secrete estrogen
how long is the follicular phase of menstruation
~14 days
where is day 0 of the ovarian cycle
on egg release, 14 days after period
what is day 0 of uterine cycle
start of period
phase that follows follicular phase
luteal phase
phases of uterine cycle
menses, proliferative and secretory
a surge in what hormone is triggered by estrogen reaching a threshold
LH
when is estrogen highest
at ovulation (day 14)
when is progesterone highest
mid secretory phase (~day 21)
function of corpus luteum
secretion of progesterone
role of progesterone
to vascularise and further prepare the endometrium for a fertilised egg
where are LH and FSH secreted from
anterior pituitary
when does basal body temperature raise during the cycle and by how much
day 14-28 (post ovulation) by 0.3C
