Question: male chest and female breasts...

what is the difference between normal male and female breasts anatomy aside from the size of the breasts and nips?

User avatar Hello Aberoo,

Actually, there is very little difference between the two. Both men and women have breast tissue; however, women have significantly higher levels of estrogen that causes the breast tissue to enlarge and the breasts to develop. The reduced levels of estrogen in men do not stimulate growth of the breast tissue.

This is why it is possible for a man to develop breast cancer. The small amount of tissue present makes the chances much less likely but still possible.

In some cases, such as in obesity, men can have elevated amounts of estrogen in the blood and can have some breast development. Boys going through puberty may also notice some breast development that tends to reduce as the boy gets older and the hormone levels stabilize back to typical adult male levels.

Best wishes.
