Menstruation Cycle

Question 1

Explain how the menstrual cycle is controlled by hormones and negative feedback

Answer 1

FSH stimulates the follicles to mature
FSH stimulates the production of oestrogen
Oestrogen inhibits the product of FSH
Follicles secrete oestrogen
Oestrogen is responsible for the repair of the uterus wall
High levels of oestrogen stimulate the release of LH
LH triggers ovulation
Corpus luteum produces progesterone
Progesterone inhibits LH and FSH
Progesterone maintains the lining of the uterus
