Aromatase is the enzyme responsible for a key step in the biosynthesis of estrogens, and aromatization is the conversion of androgens into estrogens.
Possible hypotheses for this relationship include hypogonadotropic hyperestrogenic hypogonadism due to aromatization of steroids in estrogens in peripheral tissue; direct alterations of spermatogenesis and Sertoli cell function; hip, abdominal, and scrotal fat-tissue accumulation, leading to increased scrotal temperature; and accumulation of toxins and liposoluble endocrine disruptors in fatty tissue.
Furthermore, because the risk of fibroids is greater in nulliparous women who might be subject to a higher frequency of anovulatory cycles and obese women with greater aromatization of androgens to estrone in the adipose tissue, the concept of unopposed estrogens, as an underlying cause of uterine fibroids, has been proposed in the literature (17, 18).
The absence of P450arom mRNA in granulosa layers is consistent with the findings that aromatization of estrogen from androgen is limited to the theca layer of PRFs in avian follicles (Nitta et al.
They produce androgens, mainly testosterone, but can also produce estrogen by either direct production of estradiol or by peripheral aromatization of the testosterone moiety.

Moreover, increased aromatization of testosterone in fat leads to a higher estrogenic ratio, which serves to inhibit the pituitary-gonadotropin signal, further attenuating testosterone production.
