Covina, CA, July 20, 2021 (GLOBE NEWSWIRE) — The Global Bio-identical hormone replacement market accounted for US$ 21.8 Billion in 2020 and is estimated to be US$ 46.5 Billion by 2030 and is anticipated to register a CAGR of 7.5%. Estrogen or oestrogen, is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens that have estrogenic hormonal activity: estrone, estradiol, and estriol. Estrogen is a hormone that plays various roles in the body. In females, it helps develop and maintain both the reproductive system and female characteristics, such as breasts and pubic hair.Estrogens are synthesized in all vertebrates and some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males than in females, estrogens nevertheless have important physiological roles in males.
