Also called "the change in life". This is a time in a female's life when the menstrual cycle comes to an end. This usually occurs around 45-55. This signals the end of follicle growth, ovulation, and the end of childbearing. This does not happen overnight, but happens over a few years. Some of the physiological changes are pronounced such as "hot flashes", dizziness, headache, rheumatic pain, and sweating. This can happen prematurely by removal of ovarian tissue.
