What is Estrone?
Estrone (E1), also known as oestrone, is a naturally occurring steroid and a weak estrogen, classified as a minor female sex hormone. It is one of the three major endogenous estrogens, the other two being estradiol and estriol. Estrone is primarily synthesized from cholesterol and secreted by the ovaries, though it can also be produced from adrenal androgens in adipose tissue. Estrone has far weaker estrogenic activity compared to estradiol, making it less potent.
