Why do men have nipples?

Question

When they cant breast feed.

Answer 1

Here is the full reason:

Mainly, guys have nipples because women have nipples. All embryos (the developing fetus) start out as female. Gender becomes determined around six weeks of development as a result of hormone "baths," triggered by the genetic character of the cells' chromosomes. So, the basic physiological structures are initially there, with the hormones released around the sixth week of development determining whether an embryo will develop female or male characteristics.

Nipples in men have no specific purpose, but can be very responsive to sexual stimulation. Nipples (in both men and women) are filled with many nerve endings and can be quite sensitive. They can be an erotic area (or erogenous zone) for both women and men and respond to sexual touch and stimulation. Breasts are one of the defining structures that identify all mammals in the animal kingdom, and nipples occur in both the female and male of the species. It is interesting that in the higher mammals more closely related to humans — bonobo apes, chimpanzees, and gorillas, for example — nipples are quite prominently developed in the male.

Answer 2

When you are in the womb until a few weeks after fertilisation the embryo is generally speaking female. The Nipples begin to form, as do breast buds and the reproductive glands are in the abdomen. As the hormone system comes online, testosterone is released in males and they become masculine.

The testes move down along the inguinal canal and sit is a pouch - the scrotum - which would have been the labia if the embryo was female.

But by this stage the nipples were already formed and so you end up with them. The technical term is "vestigial" meaning had a role in development but no longer used.

Answer 3

There's a book called "Why do men have nipples? Quetions you ask after the third martini" by these two guys. Go read it, it has more facts in it too, pretty funny and interesting.

to answer yout question, well they also have an X chromosome and pretty much everyone starts off as a female in the womb... until monthes later.

Answer 4

Because, as I understand it, a zygote is essentially female but becomes a "male" in a later stage of fetal developement.

Answer 5

Au contraire. Men can lactate just as well as women with the proper hormonal stimulant.
