58
What is the physiology of the menopause?
At the start of the menstrual cycle, FSH stimulates development of secondary follicles. As these follicles grow, granulosa cells secrete increasing amounts of oestrogen. In menopause, there is a decline in the development of ovarian follicles, and therefore reduced oestrogen. Reduced follicle development means that there is no ovulation. Reduced oestrogen means that the endometrium doesn't develop and therefore there is no menstruation.
