What is menopause?

Menopause comes from the Greek words meno and pause, meno being month, pause meaning to stop. Basically it's the cessation of ovarian function where the ovaries no longer respond to stimulation from the pituitary. The follicle doesn't form. It doesn't produce estrogen. There's no further ovulation, and there's also no production of progesterone. When I say no production, there's significantly less production of estrogen, progesterone, and testosterone.
