explain the role of pituitary and ovarian hormones in the menstrual cycle of humans females.

 

 

 

 

 

 

pituitary hormones:

fsh - these are the gonadotropins as they cause follicular development, secretion of estrogen by growing follicles.

lh - induces rupture of graafian follicle/ovulation and after that, the remaining part of graafian follicle transforms into corpus luteum which releases hormone-like: progesterone.

ovarian hormone:

estrogen- it helps in the growth and maturation of the follicle, as itis necessary for repair of the endometrium.

progesterone - it is necessary for the maintenance of the endometrium for implantation.
