Effective Hot Female Hormones Estradiol For Female Bodybuilding
1. Estradiol (E2), also spelled oestradiol, is a steroid, an
estrogen, and the primary female sex hormone. It is named for and
is important in the regulation of the estrous and menstrual
femalereproductive cycles. Estradiol is essential for the
development and maintenance of female reproductive tissues such as
the breasts, uterus, and vagina during puberty, adulthood, and
pregnancy, but it also has important effects in many other tissues
including bone, fat, skin, liver, and the brain. While estrogen
levels in men are lower compared to women, estrogens have essential
functions in men as well. Estradiol is found in most vertebrates as
well as many crustaceans, insects, fish, and other animal species.
2. Estradiol is produced especially within the follicles of the
female ovaries, but also in other endocrine (i.e.,
hormone-producing) and non-endocrine tissues (e.g., including fat,
liver, adrenal,breast, and neural tissues). Estradiol is
biosynthesized from cholesterol through a series of chemical
intermediates. One principal pathway involves the generation of
4-androstenedione, which is converted into estrone by aromatase and
then by 17β-hydroxysteroid dehydrogenase into estradiol.
Alternatively, 4-androstenedione can be converted into
testosterone, an androgen and the primary malesex hormone, which in
turn can be aromatized into estradiol.
