Correct answer: A. Only by inhibition of Luteinizing Hormone.
- A. Only by inhibition of Luteinizing Hormone.
- B. Inhibition of FSH & stimulation of LH.
- C. Inhibition of LH & stimulation of FSH.
- D. Inhibition of both FSH & LH.

About Menstrual Cycle
The menstrual cycle covers the coordinated changes in the ovaries and uterus, including menstruation, follicular growth, ovulation and corpus luteum formation. It links follicle-stimulating hormone, luteinizing hormone, oestrogen and progesterone with endometrial changes, and distinguishes the ovarian cycle from the uterine cycle and the hormonal events of pregnancy.
