During the first half of the menstrual cycle, the hormone that rebuilds the lining of the uterus is
- A. progesterone
- B. LH
- C. FSH
- D. oestrogen
Explanation
Oestrogen from the developing follicle drives the endometrium to proliferate after menstruation. Progesterone takes over after ovulation to maintain the rebuilt lining, so the two hormones divide the cycle between them.
