Answer to Question #123041 in Zoology for preeti

Question

Explain the hormones and their respective functions during the female menstrual cycle.

Answer 1

Follicle-stimulating hormone (FSH): Stimulates egg development and the release of oestrogen.

Luteinising hormone (LH): Stimulates the release of the egg (called ovulation). Stimulates oestrogen and progesterone production.

Oestrogen: causes growth of the uterine lining. Inhibits FSH. Stimulates the release of LH and hence release of the egg. Inhibits LH after ovulation.

Progesterone: maintains the uterine lining. Inhibits LH after ovulation.
