Menopause essentially takes place when a woman ceases to ovulate and when her menstruation stops as well. Women also lose their fertility or the ability to bear children during the menopausal stages. Ovulation is no longer possible since at this point, the ovaries cease producing progesterone and estrogen for fertility. While estrogen is often considered as a sex and reproductive system hormone, it is also responsible for a range of functions within a woman’s body. In fact, there are estrogen receptor cells found in other parts of a woman’s body such as the vagina, bladder, liver, brain, skin, heart, and bones. In order that these organs can function fully, estrogen is needed. Estrogen is necessary in keeping the skin supple, the arteries unblocked, and for the bones to form properly. At this menopausal stage of a woman’s body, other organs take on the job of estrogen production. Since the ovaries are no longer capable of producing estrogen, other bodily organs acquire the role of estrogen production, as well as the production of other necessary hormones. The endocrine glands moreover are known to produce the needed hormones, so as to maintain the proper functions of the body. Once a woman enters the menopausal stage, the estrogen levels of the body drop significantly, however, the estrogen hormone does not disappear completely.
