Female menopause represents the end stage of a natural transition in a woman's reproductive life. Female menopause is the point at which estrogen and progesterone production decreases permanently to very low levels. In menopause, the females ovaries stop producing eggs and a woman is no longer able to get pregnant naturally.
On average, female menopause, also known as the "change of life",
occurs by the age of 51 and can be confirmed by 12 successive months without menstruation.
Contrary to popular use, the term female menopause does not refer to the process of hormonal change that results in the end of menstruation and fertility. Rather, menopause in females is the end state of that process, the permanent cessation of a woman's menstrual period. The symptoms for which female menopause is known are actually part of perimenopause, the transitional stage between premenopause and menopause.
Once the event of menopause has occurred in females, a woman is said to be in postmenopause.
