why do men have nipples
We are long hairy, there are three middle ear bone mammals, women can be offspring for breastfeeding, by the breast, breast
Is a special deformation of sweat glands. Although only women have breasts, but we are in the embryo regardless of gender, are the same. In development, the embryo has been a female model, until six weeks later, male embryos in the sex chromosome appeared. At this point, male embryos began to develop its sexual characteristics. Therefore, the man who kept the nipple, there are some breast tissue, men and even breast cancer. In some cases, men will have breast hyperplasia. Abnormal male mammary gland hyperplasia is called "male breast development". This disease can be caused by the use of anabolic steroids. So, if Barry Bonds years later to participate in the "old star game", long slack off the large men's breasts, then, I think we will have a lot of debate on the steroids.
