At the start of the menstrual cycle, rising levels of FSH stimulate
- A. ovulation
- B. the shedding of the endometrium
- C. the development of follicles in the ovary
- D. the formation of the placenta
Explanation
FSH, follicle stimulating hormone, recruits a batch of follicles at the beginning of the cycle, and the growing follicle then secretes oestrogen. Ovulation comes later, triggered by LH, and the placenta only forms after pregnancy begins.
