Estrogens

Estrogen is one of the most important hormones for women and interacts with multiple organ systems via distant organs and plays an important role in the physiological events that occur in women's lives. [1] The presence of endogenous hormones in plasma is a problem in pharmacokinetic and bioanalytical considerations with regard to endogenous baseline levels, low plasma concentrations, analytical range, and potential for effects of circulating hormones It is casting. In order to quantify plasma concentrations of estrogens in clinical trials it is necessary to develop and validate assays with appropriate sensitivity, selectivity, accuracy and accuracy.

Estrogen agonists / antagonists: estrogen agonists / antagonists (also known as selective estrogen receptor modulators or SERMs) are approved for the prevention and treatment of osteoporosis in postmenopausal women. SERM is not an estrogen, but certain tissues have estrogenic effects and other tissues have estrogen blockade. Estrogen and hormonal therapy: The combination of estrogen, estrogen and progesterone (hormonal therapy) is approved for the treatment of moderate to severe hot flashes and vaginal dryness, which may be related to the prevention of postmenopausal osteoporosis and menopause . Estrogen without progesterone is recommended only for women who have undergone hysterectomy (surgical resection of the uterus). Estrogen increases the risk of endometrial cancer and progesterone reduces this risk.

Estrogen is an important hormone for sexual and reproductive development, mainly women. They are also known as female sex hormones. The term "estrogen" refers to all hormones that are chemically similar in this group, estrone, estradiol (mainly to women of childbearing age) and estriol. Estrogen also helps regulate the menstrual cycle and controls the growth of the endometrium in the first part of the cycle. If the female ovum is not fertilized, the estrogen level dramatically decreases and menstruation begins. When eggs are fertilized, estrogen is used along with progesterone (another hormone) to prevent ovulation during pregnancy.

Estrogen is the major estrogen. Estrogen adjusts your menstrual cycle and prepares your uterus for pregnancy. Your estrogen levels may fluctuate dramatically during premenopausal perimenopause. When you reach menopause, your estrogen levels decline markedly. Changes in estrogen levels and subsequent decline cause characteristic symptoms of menopausal disorder. These include hot flashes, night sweats, mood changes, irregular menstruation and the like. Soy is the most abundant dietary source of phytoestrogens. It is particularly rich in phytoestrogens called isoflavones. The soy isoflavone binds to the estrogen receptor in the body. There are hundreds of studies on isoflavones and soybeans, the results are contradictory. However, according to the American Journal of Clinical Nutrition, there is ample evidence that soy food helps solve some diseases related to menopause.
