2. Product Description: Estradiol is a steroidal estrogen. There are two types of α and β, and the α type has a strong physiological effect. Wintersteiner et al. (Wintersteiner et al. 1935) once extracted it from pregnant horse urine, and it can also be obtained from pregnant maternal urine, human placenta, porcine ovary, etc. It is also present in the testis or urine of male horses. Because it has a strong sex hormone effect, it is believed that it or its ester is actually the most important sex hormone secreted by the ovaries

The role of estrogen can promote the development of secondary sexual characteristics and the final formation of sexual organs in underage women. In adult women, in addition to maintaining the above-mentioned secondary sexual characteristics, it can also cause a series of changes in the endometrium, resulting in periodic menstruation. It can also increase the activity of the uterus and fallopian tubes, and increase the sensitivity of uterine muscles to oxytocin. In addition, estrogen can also increase the deposition of bone calcium salts, accelerate the closure of the epiphysis, and increase serum triglycerides and phospholipids in large doses, causing water and sodium retention. In larger doses, estrogen can also act on the hypothalamus-pituitary system, inhibit the secretion of gonadotropins and prolactin, and can counteract the main effects of androgens.
