Female reproductive physiology Flashcards
when does puberty start for females
8-13 years
functions of female reproductive system
produce sex hormones
produce functioning gametes (ova)
support and protect developing embryo
function of GnRH
secreted by hypothalamus and stimulates AP to secrete FSH
function of FSH
stimulates ovaries to develop mature follicles
follicles produces high levels of estrogen
function of LH
stimulates release of ovum by follicle
follicle is then converted to corpus luteum which secretes progesterone
function of estrogen
stimulates repair of endometrium of uterus
inhibits production of GnRH
function of progesterone
stimulates thickening and maintains endometrium
inhibits production of LH
function of hCG
stimulates production of progesterone
follicular growth regulation
- GnRH rises in response to decline in inhibin and sex steroids stimulating rise in FSH and LH secretion
- FSH stimulates new follicle growth
- LH induces thecal cell growth, vascularization and androgen synthesis
what cells does LH act on
thecal and granulosa cells
what cells does FSH act on
granulosa cells
