Why do men have nipples?!


Question:

Answers:
for piercing and sucking

Other Answers:
Because otherwise we would look funny in bathing suits.

So that stupid a$$holes apply their nipple techniques to hurt you.

so us girls can bite them. lol i don't know really

I asked this question awhile back.

Men and women grow in the womb the same for quite some time. Then, men become men and women become women. Men also have milk glands, but they are very small and pretty useless.

The real reason why men have nipples, is because before the sex organs became defined, all fetuses were females. Has something to do with the chromosomes.

Because all fetuses start out as females.
Then they female fetuses change into males later on at about the second month of gestation. Seriously!

To hang up a piercing!

because nipples are corks that hold all of our insides inside of us. with out them we would leak. Just like we do people have belly buttons

technically it's because we all start out as females in the womb.up to a certain time, then finish forming into a male or female. but the nipples remain..

truth..

When a male embryo is developed, It starts at the head. In this sense, all men are women, because we develope nipples before, by the toss of a coin, we are decided to be men. This is also why the testicles are simply dropped ovaries.

Well all baby bodies start the same and they only turn into men with the Y Chromosone. So we all have to start with nipples in the beginning. We just don't all have peckers in the end

Because those tissues were predetermined to become nipples, just that men received the hormones as embryos to not grow breasts. Same thing for females with the clitoris it just never received enough male hormones to grow into a penis during the embryonic stage. Hormones are the reason why men can grow breasts (man boobs) and how women bodybuilders can enlarge their clitoris (steroids).

Actually this may sound kind of weird but. In a couple of tribes in rural africa, males have been known to produce a milky substance from their nipples which is used to breast feed babies.true story. as for us normal people when a boy hits puberty his nipples get hard and sensetive. But not all boys.and it only lasts like a week.

The nipples provide a focus point for the male chest. They direct the eye to the curve of the pectoral muscle.

Men and women are mammals (from the Latin mamma breast) a species that have breasts and feeds its young with milk. The human embryo has tissue that will evolve into breasts. Both male and female babies are born with nipples and ducts intact. It is the presence of genes that direct hormones to differentiate the breast tissue. The Y chromosome stimulates hormones such as testosterone to form male features.

Insufficient or defective testosterone, poor tissue responsiveness, or an unbalance of other hormones like Estrogen and Prolactin can cause female like breasts even in men (Gynecomastia). At birth, the small amount of the mother's estrogen in the baby can result in small breasts that usually resolve. There can be an inbalance of hormones during male puberty that can result in temporary breast growth, which for most resolves. There are many medical problems and drugs that can cause male breast growth

The nipple is actually the central protrusion inside of the pigmented areola. There is a thin muscle just under the skin that when stimulated, tends to flatten the puffed male nipple areola. This muscle when stimulated in a breast feeding woman, projects the nipple for the baby. Nerves that innervate the nipple / areola can produce pleasure for both men and women.

That's actually a book.Why Do Men Have Nipples? Hundreds of Questions You'd Only Ask Your Doctor After Your Third Martini. by Mark Leyner.



Evolutionary biologists, whose job it is to explain variety in nature, are often expected to provide adaptive explanations for such "why" questions. Some traits may prove—through appropriate tests—to be best explained as adaptations; others have perfectly good evolutionary, but nonadaptive, explanations. This is because evolution is a process constrained by many factors including history, chance, and the mechanisms of heredity, which also explains why particular attributes of organisms are not as they would be had they been "designed" from scratch. Nipples in male mammals illustrate a constrained evolutionary result.
A human baby inherits one copy of every gene from his or her father and one copy of every gene from his or her mother. Inherited traits of a boy should thus be a combination of traits from both his parents. Thus, from a genetic perspective, the question should be turned around: How can males and females ever diverge if genes from both parents are inherited? We know that consistent differences between males and females (so-called sexual dimorphisms) are common--examples include bird plumage coloration and size dimorphism in insects. The only way such differences can evolve is if the same trait (color, for example) in males and females has become "uncoupled" at the genetic level. This happens if a trait is influenced by different genes in males and females, if it is under control of genes located on sex chromosomes, or if gene expression has evolved to be dependent on context (whether genes find themselves within a male or a female genome). The idea of the shared genetic basis of two traits (in this case in males and females) is known as a genetic correlation, and it is a quantity routinely measured by evolutionary geneticists. The evolutionary default is for males and females to share characters through genetic correlations.


The uncoupling of male and female traits occurs if there is selection for it: if the trait is important to the reproductive success of both males and females but the best or "optimal" trait is different for a male and a female. We would not expect such an uncoupling if the attribute is important in both sexes and the "optimal" value is similar in both sexes, nor would we expect uncoupling to evolve if the attribute is important to one sex but unimportant in the other. The latter is the case for nipples. Their advantage in females, in terms of reproductive success, is clear. But because the genetic "default" is for males and females to share characters, the presence of nipples in males is probably best explained as a genetic correlation that persists through lack of selection against them, rather than selection for them. Interestingly, though, it could be argued that the occurrence of problems associated with the male nipple, such as carcinoma, constitutes contemporary selection against them. In a sense, male nipples are analogous to vestigial structures such as the remnants of useless pelvic bones in whales: if they did much harm, they would have disappeared.
In a now-famous paper, Stephen Jay Gould and Richard C. Lewontin emphasize that we should not immediately assume that every trait has an adaptive explanation. Just as the spandrels of St. Mark's domed cathedral in Venice are simply an architectural consequence of the meeting of a vaulted ceiling with its supporting pillars, the presence of nipples in male mammals is a genetic architectural by-product of nipples in females. So, why do men have nipples? Because females do.

to remind women that men have erogenous zones too

Becaue when a baby is first concieved, there is no way to distinguish between a male and female. The male and female body come from the same mold.Thats why men have nipples. It's not until weeks into the pregnancy that the baby begins to grow thier particular body parts. I dont know how to explain it. I read it in that new book, Why do men have nipples?

Because they are human. All babies start out as female, and around 8 weeks either remain that way or start to develop male organs. What would be ovaries drop out and become testes, along with the rest of the changes. Although the nipples are already part of the package, males do not develop breasts for the purpose of providing nourishment for their babies.

Evolutions first concern is to make a fetus that can survive and then it makes a fetus capable of reproduction.The fetus develops into a huge number of cells before sex is determined. During this the genetic makeup is common. The sex of the child isnt determined on the first day of conception. Thus men and women have many similar features like 2 hands 2 legs etc etc. Men also have breasts like women do but they are far less developed and far less sensitive.

Also the genetelia is common intially in the first couple of weeks. Thats why sex determination is very tough in the intial phases of the pregnancy.
Nipples become a vestigial organ in men.

In utero all babies grow nipples (and gonads). This is before the sex of the baby is fully expressed (hormonally). As the baby gets older in utero the hormones play a more active part - females grow the nessessary internal parts to the breast to allow for lactation, males don't. The gonads become testis in males and ovaries in females.

Hope this helps :)
