why do males have nips?
466168
because males MAY use them as stimulation receptors, they aren't ruled out by evolution\nso infact that are used, just not like females use them (think about it, if a male has nipples and uses them this way, then he would be able to spread his charateristic to more females thereby increasing the popularity and favorability of the trait)\nas for the question of why they there in the first place...\nits one of those characteristics that are kept when the baby is developing in the womb

men do not have cherries or periods. if this is happening then he has a serious infection, or STD. please if u know someone with this tell him to get checked

Both men and women have boobs but if you are referring to the unusual enlargement of the male breast (male breasts are supposed to be flat) then this means that they have more estrogen hormones than androgen hormones. Normally, men have a high level of androgen but genetic aberrations, obesity, infection, malignancy, hormonal imbalances due to abnormal conditions of the pituitary gland and the adrenal glands, may lead to an incrased secretion of estrogenic hormones in males manifesting as gynecomastia or an abnormal increase in the size and shape of the male breast. Generally, gynecomastia is not a serious condition unless it has been diagnosed to be malignant.

'cause we Cancers are so darn sexy! Just kidding. Probably because Cancers are very nurturing and protective and these guys just want to be taken care of.

Because the chest looks funny without them.  And some guys enjoy having theirs bitten.

I actually do know this.  In eutero, your nipples are formed before your sex organs develop.  Women go on to use hormones to create breasts, but for men, there is absolutely no reason to have them.\n\nThat is the 100% truth...

The Straight Dope says, "To tell you the truth, nobody really knows. The best explanation I've been able to find (and frankly it doesn't explain very much) is that nipples aren't a sex-linked characteristic. In other words, nipples are just one of those sexually neutral pieces of equipment, like arms or brains, that humans get regardless of sex." \n\nIt's also notable that the fetus starts to develop nipples long before any other sex-linked characteristics.

ASK THE EXPERTS: BIOLOGY   \n \n \n \n \n \nWhy do men have nipples?  \n \n \nAndrew M. Simons, a professor of biology at Carleton University in Ottawa, Ontario, explains. \nLike all "why" queries, the question of why men have nipples can be addressed on many levels. My four-year-old daughter, always suspicious of a trick when asked such obvious questions, answered: "because they grow them." In search of the trick answer, she quickly added that "chests would also look pretty funny with just hair." \n \n \nADVERTISEMENT (article continues below) \n \n \n \nEvolutionary 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. \nA 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. \n\n \nThe 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. \nIn 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 v

There is a book that answers this question, along with a ton of other odd medical questions called "Why Do Men Have Nipples?"\n\nHaving read the book I now know that men have nipples because, in the womb we all start out as girls.  It's only after a certain point that the fetus' sexual organs become "outies".  So rather than a clitoris and ovaries,  Mr. Winkie and his two friends pop out.  That is if the baby is genetically destined to be a boy, of course.

the truth is most guys like that sorta stuff so just take my advice for it dont remove them\nbut then again they dont like thick and black ones so just bleach the hair and dye it red or brown or what suits you.\nAnd if you still wanna do something with your knockers just buy special enzymes that make your nips pink ,if they already are pink the cream will stimulate you ALOt

WHY DO WOMEN HAVE BOOBS?

Because when the baby is forming, it starts off with a female template. Later, if it's a boy, that kicks in and it starts to form as a male. The baby has already developed nipples by this time, so they keep them.

no. men have nipples to prevent drowning when wading in water. watch men and you see them stop wading out when water reaches nipples, if we had buttons we would keep going and drown

actually, I think men were given nipples, so they have something to play with in case they loose their balls

I don't really know who are bo boys ^_^. But, evolutionary speaking, it is a sign of a healthy female.\nBig boobs provides more breastmilk for babies, and big butt (usually mean big waist), means more efficient in labor.\nThe same reason why girls like muscular, thick lips boy.
