17Beta-estradiol Powder USP36 Standard Briefing :
Estradiol is essential for the development and maintenance of female reproductive tissues, but Estradiol also has important effects in many other tissues including bone. While estrogen levels in men are lower compared to women, estrogens have essential functions in men as well. Estradiol is found in most vertebrates as well as many crustaceans, insects, fish, and other animal species.
Estradiol is a sex hormone that is present in both males and females, and is the most important form of estrogen in humans. In women, it plays a key role in the development and functioning of the reproductive system, as well as in the growth of certain bones. It also governs the distribution of body fat in women and is the main hormone responsible for the fact that women are shorter than men, on average. Both the ovaries and the adrenal glands produce it.The menstrual cycle in women involves predictable variations in the levels of several hormones, with estradiol being one of them. It is involved in the ovulation process and prepares the inner lining of the uterus for implantation, should the egg be fertilized. Certain tests done on baboons and other primates have indicated that his hormone also plays a continual role in maintaining a pregnancy, helping it to last for the full gestation period.As a sex hormone, it also triggers many of the developments of the reproductive system that begin in puberty. It is present throughout the reproductive years, and declines during and after menopause. This decline is precisely what causes many of the symptoms of menopause, such as hot flashes and night sweats, vaginal dryness, and the loss of bone mass that may lead to osteoporosis.
