Hormonal Control of Reproduction

how does the thickness of the endometrium change throughout the menstrual cycle

decreases during menstruation

increases between day 7-14 due to oestrogen

maintained from day 14-28 by progesterone

what is function of FSH

stimulates primary follicle maturation

stimulates oestrogen secretion

what is the function of oestrogen

stimulates anterior pituitary gland to secrete LH

stimulates new endometrium production

inhibits apg secreting FSH

what is the function of LH

causes graafian follicle to release secondary oocyte in ovulation

stimulates corpus luteum formation from graafian follicle which secretes progesterone

inhibits oestrogen secretion

what is the function of progesterone

maintains endometrium in preparation for blastocyst implantation from day 14-28

stimulaties oestrogen secretion

inhibits FSH and LH secretion

what happens if implantation doesn’t occur

corpus luteum degenerates

progesterone levels decrease

endometrium breaks down

FSH is no longer inhibited so cycle restarts
