What role does estradiol play in the human body?
β-Estradiol powder is the most active and physiologically important component of estrogen. Its main function is to promote the development of female reproductive organs, maintain secondary sexual characteristics and reproductive function, as well as some very important non reproductive functions. Although both men and women have this estrogen, its levels are much higher in women.
1. Maintain female secondary sexual characteristics: promote breast development, enlarge breasts, darken areola and nipple color; Make the pelvis wide and the buttocks thick; Increase subcutaneous fat to make the skin smooth and delicate.
2. Regulating menstrual cycle: participating in the growth and shedding process of the endometrium, promoting endometrial thickening, and preparing for the implantation of fertilized eggs; Adjust the amount and duration of menstruation.
3. Affects reproductive function: plays an important role in the development and maturation of follicles, promoting ovulation; Maintaining the stability of the uterus during pregnancy helps with embryo implantation and development.
4. Protection of cardiovascular system: It has a certain antioxidant effect, helps to reduce cholesterol levels, prevent atherosclerosis, and has a certain protective effect on the cardiovascular system.
5. Promote bone metabolism: participate in the regulation of bone formation and resorption, maintain bone density, and prevent osteoporosis.
6. Impact on the nervous system: It may have a certain impact on the development and function of the nervous system, related to emotions, cognition, and other aspects.
Why is it necessary to check estradiol levels in early pregnancy?
Because pure estradiol can promote the growth of the endometrium, which is beneficial for the healthy development of embryos. So after pregnancy, the level of estradiol in the body will increase, and as the number of days of pregnancy gradually increases, progesterone and estradiol will continue to rise. If hormone levels are not increased, especially if the nutrition of the fertilized egg cannot keep up, it will cause miscarriage. Therefore, it is recommended to supplement some estradiol and folic acid regularly to prevent threatened miscarriage and fetal malformation.
