Visit here for surgeons of gynecomastia surgery at hospitals of Goa in India. In female transgenetics, over expression of aromatase promotes the induction of hyperplastic and dysplastic changes in breast tissue. Over expression of aromatase in male transgenics caused increased mammary growth and histological changes similar to gynecomastia, an increase in estrogen and progesterone receptors and an increase in downstream growth factors such as TGF-beta and bFGF. Interestingly, treatment with an aromatase inhibitor leads to involution of the mammalian gland phenotype. Thus, although androgens do not stimulate breast development directly, they may do so if they aromatize to estrogen. This occurs in cases of androgen excess or in patients with increased aromatase activity. If anything, increased demand on surgeons of gynecomastia surgery at hospitals of Goa in India due to medical tourism may result in their expansion.
