Gadis Cantik Memek Sempit

Did you know! From conception until sexual differentiation, all mammalian fetuses within the same species look the same, regardless of sex. In humans, this lasts for around 6 weeks, after which genetically-male fetuses begin producing male hormones such as testosterone. Usually, males' nipples do not change much past this point; however, some males develop a condition known as gynecomastia, in which the fatty tissue around and under the nipple develops into something similar to a female breast.

This may happen whenever the testosterone level drops. Gynecomastia, although not as severe, may occur in pubescent boys undergoing physical changes due to the rapid and uncontrolled release of hormones, including estrogen.
