Summary:
- Ovulation, the release of an egg from an ovary, is part of the menstrual cycle.
- Menstruation is the process in which the endometrium of the uterus is shed from the body.
- The menstrual cycle is controlled by hormones from the hypothalamus, pituitary gland, and ovaries.
- For most women, menstrual cycles continue until their mid- or late- forties.
- Then women go through menopause, a period during which their menstrual cycles slow down and eventually stop.
