Menopause is a very natural biological process that occurs in females as they age, resulting in a variety of symptoms. The naturally occurring factors that lead to menopause include a decrease in the production of estrogen and progesterone, which are the hormones that are necessary for regulating the menstrual cycle. These hormones are produced in the ovaries, and the natural aging process in females slows down the production of these hormones as well as the number of eggs that are released monthly, resulting in significant anatomical changes through shifting hormone levels including decreased frequency of periods and decreased fertility. Menopause can be brought about much earlier if the individual has undergone a surgical procedure or condition that has resulted in the removal or damage to the ovaries. Treatments for cancer including chemotherapy and radiation are known to cause damage to the ovaries, often resulting in early menopausal symptoms.
