Estradiol is one of the most important sex hormones in both men and women. It is an estrogen hormone that plays a crucial role in the development and regulation of the female reproductive system. Estradiol is produced primarily by the ovaries in women and to a lesser extent by the testes in men and the adrenal glands in both sexes. In women, estradiol is responsible for the development of secondary sex characteristics during puberty such as breast development, widening of the hips, and the growth spurt. It regulates the menstrual cycle by stimulating the growth and shedding of the endometrial lining of the uterus during the follicular and luteal phases. Estradiol prepares the body for pregnancy by thickening the uterine lining and maintaining it during early pregnancy. Estradiol also impacts other tissues in the body. It helps maintain bone density and cardiovascular health in women. After menopause, estradiol production drops dramatically leading to symptoms like hot flashes, vaginal dryness, and osteoporosis. Hormone replacement therapy containing estradiol may help relieve these symptoms. In men, estradiol plays a role in sperm maturation and regulating libido and erectile function. It also contributes to bone density and cardiovascular health. Abnormally high or low levels of estradiol in men can negatively impact fertility and cause gynecomastia. Estradiol levels can be measured with a simple blood test. Medications like birth control pills contain forms of estrogen, including estradiol, to maintain female hormone levels. Estradiol is also available in creams, patches, sprays and tablet form to treat symptoms of menopause and hypoestrogenism.
