Hormones involved in Menstrual Cycle

Can be divided into 2 groups :
 i) hormones that control the changes in the ovaries - FSH and LH
 ii) hormones that control the changes in the uterus - oestrogen and progesterone

FSH
secreted by - anterior pituitary gland
stimulates the development in the ovary

LH
secreted by - anterior pituitary gland
stimulates ovulation, the development of corpus luteum
promotes the secretion of progesterone

Oestrogen
secreted by - follicle cells of the ovary
stimulates further growth of the follicles
promotes the repair of endometrium from 12th day of the menstrual cycle, it has positive feedback action on the secretion of FSH and LH

Progesterone
secreted by - corpus luteum
stimulates the endometrium to become thick, folded & highly vascular (enriched with blood vessels) for the implantation of an embryo
inhibits the secretion of FSH & LH to prevent the development of Graafian follicles &  ovulation
