Explanation / Answer

28 day uterine cycle due to hormonal changes

Uterine endometrium is shed off.

Oestrogen -

FSH- Follicular stimulating hormone

This causes growth of the ovarian follicles

LH- Luteinizing hormone

Around 14th day of the cycle, due to LH surge dominant follicle or the graafian follicle releases the oocyte. This is called ovulation.

Progesterone - Corpus luteum formed after ovulation releases progesterone. This hormone prepares the uterine lining for potential implantation to establish pregnancy. If no implantation in two weeks, corpus lute um in volute. So no progesterone and uterine lining is shed of as menstruation.

So,

Menses- Proliferative phase-secretory phase (uterine cycle)

Pre proliferative phase- Follicular phase - Luteal phase ( ovarian cycle)
