Estrone is primarily derived from metabolism of androstenedione in peripheral tissues, especially adipose tissues. Individuals with obesity have increased conversion of androstenedione to Estrone leading to higher concentrations. In addition, an increase in the ratio of Estrone to Estradiol may be useful in assessing menopause in women. Estriol, an estrogen that has virtually been ignored by the mainstream medical community, is one of the three principal estrogens produced by the body. Estriol was originally thought to have little significance due to its weak estrogenic activity when compared with estrone and estradiol.
