17-B-Estradiol (E2) is an important steroid hormone present in both males and females. It plays a key role in the development and functioning of the reproductive system, as well as the skeletal and cardiovascular systems. E2 is usually measured to monitor any hormonal alterations, for example, during menopause, early stages of pregnancy, amenorrhoea, dysmenorrhoea, or to monitor IVF patients. The presence of female-like characteristics in males may require Estradiol measurements as well. INCREASED levels of Estradiol are seen in normal pregnancy, and puberty. HIGH levels chcan be associated with tumors of the ovary, testes, or adrenal cirrhosis. DECREASED levels are seen in Turner syndrome, hypopituitarism, hypogonadism, or after menopause.
