Putting on the man is immature version of female breast, so the breasts are not ripe, "explained Dr. Andri Wanananda, MS, sexologist and lecturer at the Faculty of Medicine Tarumanegara University, when contacted detikHealth.

Dr Andri explains when male and female embryos have the same tissues and body parts. So there is a kind of 'template' that makes the male and female bodies have the same shape, including the nipples that exist in both sexes.

It was only then that at a certain gestational age there was an effect of genes, Y chromosomes and testosterone hormones that brought about changes and masculinity to the embryo.

Testosterone improves penile and testicular growth. But because the nipple on the male embryo already exists before the process begins, then the nipple is still there although it will not be enlarged when entering puberty later.

The nipple and breast tissue in males does not have a female function, which is lactation, except it may protect the heart and lungs from injury, as reported by About.com.

However, nipples in men also still function as one of the erotic zones, although not as sensitive to women.

Although not able to enlarge like breasts and nipples in women, in fact breast and nipple in men can also produce milk and breast cancer.

The level of the hormone estrogen that is usually found in women was also found in the male body. In the event of certain conditions or diseases affecting the hormone, the breast tissue in males may grow, called gynacomastia. This condition causes male breasts can also produce milk.

Gynacomastia or abnormal enlargement of male breasts, more commonly seen in adolescence, developmental periods when hormones fluctuate a lot. It is also seen in some men with liver disease and sometimes on alcoholics.
