Gynecomastia is a benign overgrowth of the male mammary gland that results from an increased ratio of estrogen to androgen action. It must be distinguished from lipomastia and mammary carcinoma. Gynecomastia is either physiological at different stages of life (birth, adolescence, senescence), or secondary to diseases causing a drop in androgens/an increase in estrogen, or related to the taking of drugs or narcotics. Nowadays, the list of drugs associated with gynecomastia is well known, and for many years some experimental cases of cannabis use in male mammals have revealed the onset of gynecomastia with falling testosterone levels.
