How Does Menopause Happen?

The ovaries contain follicles in women who have eggs. At birth, there are approximately 500,000 eggs. At puberty, only about 75,000 eggs left. Only about 400 to 500 eggs mature and emerge as adults. The rest degenerate over the years. During the breeding season, a gland in the brain generates hormones that cause an egg to be released from the ovary each month. The follicle then produces the sex hormones estrogen and progesterone, thickening of the endometrium. Fortified foods are ready to receive and nourish a fertilized egg that could become a baby. If fertilization does not occur, estrogen and progesterone fall, cancels the lining of the uterus and menstruation occurs.

Hormone production in the ovaries begin to decline from mid-thirties. In the fifty years, the process accelerates and hormones fluctuate more, so that irregular menstrual cycles and unpredictable episodes of heavy bleeding. In the first half of the fifties, periods finally end. However, estrogen production is completely stopped. The ovaries decrease their output significantly, but produce a small amount. In addition, some of estrogen in fat cells by the adrenal glands that occurs. To make progesterone, the hormone of other works in the second half of the menstrual cycle, a lining of the uterus as a viable home for an egg, and throw away the food when the egg is not fertilized. If you miss a period, usually means that your body does not produce enough progesterone to break down the uterine wall. By contrast, estrogen levels remain high, but no bleeding.

In postmenopausal hormone levels are not always uniformly lower. Alternately up and down again. These levels of fluctuating hormone levels, ovarian effects in other glands in the body, along with the endocrine system. The endocrine system controls growth, metabolism and reproduction. This system must constantly readjust to work effectively. Ovarian hormones and in all other tissues, including the breasts, vagina, bones, blood vessels, gastrointestinal tract, urinary tract and skin.
