i was just wondering why do men have nipples?

Just in case you want a serious answer, men have nipples because during the early days of a person’s development (fetus) everyone is female. Males become males later due to hormones. The nipples are created before the hormones kick in.

Before asking that question, you need to understand what evolution is.   Evolution describes genetic change over time in response to environmental selection pressures on a species.  This means that advantageous changes are not weeded out.  In fact, all traits which do not negatively impact survival or reproduction, will not be weeded out.  Nipples on a man fall into this category.  Further, if anything, nipples are PROOF of evolution - In general, all species evolved from a prototype ancestral condition; thus, there exists genotypic and phenotypic similarities between members of a species and between related species.  All mammals have nipples, male or female, because our earliest mammalian ancestor had nipples (in fact, what makes us all "mammals" is the ability to produce milk via "mammary" glands to nurse our young).  Thus, both genders of our species (and all mammalian species) have nipples.  Nipples are a conserved evolutionary trait and are not gender-specific.

You should talk to his doctor about this.  The main reasons people get "man boobs" are that they're either significantly overweight, or they have a hormonal imbalance.  If you're son is not overweight, he may have a hormonal imbalance, which should be evaluated by a doctor.

Men have nipples. That is just part of human anatomy for males and females. \n\nAs for beards, that is also part of our biology. Men\nhave testosterone hormone which increases their hair growth at puberty and then into manhood.\n\nSome woman with high testosterone levels also have hair growth on face, for which most use some form of hair removal creme or other method\n\nBeards are a mans preference. My husband loves to groom himself with different face fashions  mustache, gotti\nsideburns, sideburns that frame chin. \n\nHave you ever seen a really long mustache. I wonder about\nthose\n\nI know for years its been part of men and fashion statement.\n\nHow about those long long beards like zztop, very funky.\n\nBluebeard, Jesus Christ,  Saints, Monks, Pirates, Rock Stars, Johnny Depp in the Pirates of the Caribbean (oooh)The bearded lady at the circus. \n\nuh oh, i'm going off now. \n\nBeards. They feel fuzzy and scrape your face when he kisses you. They can stimulate you when they rub up against your body. Hmmm. Think about that. They can make a man look \ndistinguished or unkempt. They can have things crawling in them if your not careful soooo WATCH OUT when you kiss the bearded men. And check out what happens when you pinch their nipples!

I remember hearing it this way:  (in layman's terms) When we are in the womb, the genetics that determine whether we will become a man have not "kicked in" yet. At that time the mammary glands are beginning to develop. Then the "male" codes kick in and stop the process after the nipples have developed. They then become just decorative.

Nipples are not too much attractive as the whole breast are.But its very sensitive,so it should be covered for its sensitivity.

I have inverted nipples...they do come out....they are sensitive thats for sure....sometimes a simple touch will turn you on but a touch too hard will hurt. They are actually more sensitive I believe thats why it's hard to breastfeed when you have inserted nipples.

Men & women start to develop as one entity, by the time the sex is determined the nipples on males have started to develop. Obviously the progression stops & men do not develop full breasts.

A human embryo begins developing as a female (or some say anatomically indistinguishable), complete with mammary glands and ducts.  A couple of months later the hormones kick in and well...boys will be boys.  Most people (scientists, researchers, et cetera) say the nipples are from that "indistinguishable period."\n\nAs far as all land mammals having nipples, I had to Goooogle that one.  The site I found said all land mammals have nipples except stallions.

Men's nipples don't have a purpose.  When a baby is developing in the uterus, they all start out as female, hence the nipples developing.  Basically in order for a male to develop from there is a genetic fluke which sends signals to start developing male organs.  The only sign that is left that all men started as females at the most basic level of life is the nipples.\n\nFascinating, huh?

ALL nipples are sexy (thats' cause I love women so much, \nespecially their breasts). Leave nature alone, I'm sure you're\nbeautiful just as you are.

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

Somebody knows, ask an anatmoist. Nipples show up on a fetus before the fetus starts producing sex hormones (estrogen or testosterone). At this point in development the fetus is neither male nor female in appearance. Sex was determined at the moment the egg (X) was fertilized by a sperm (X or Y). This debunks the myth we all started female. As to why nipples develop so early, no one knows that answer.

because men still have the capabiltiy to produce milk...it may be weird but through the power of suggestion or with hormones it can be done... and has already been done...\n\nmost people might say its vestigial but that wouldnt be so if its still fully functional... anyway hope this helps..\n\nps: perhaps one day in the future the need will arise for men to use them (once again?)

for foreplay ........ it can be very sensual for a man to have his nipples played with just as with a female ......... talk to your partner ..... ask him/her these questions and learn their likes and dislikes

When a child is conceived, it is firstly a girl. Later in its development it can turn into a boy. So the male nipples are probably a remainder of the girl he used to be when it was an embrio.

It has to do with when the nipples develop in utero (when we are a fetus)...\nOne interesting consequence of the developmental set-up just described is that during the very early stages of fetal life, before the sex hormones have had a chance to do their stuff, all humans are basically bisexual. Among other things, you have two sets of primitive plumbing--one male, one female. Only one set develops into a mature urogenital system, but you retain traces of the other for the rest of your life.\nHuman nipples appear in the third or fourth week of development, well before the sex characteristics. (The sex hormones start to assert themselves at seven weeks.) As many as seven pairs of nipples are arranged along either side of a "milk line," a ridge of skin that runs from the upper chest to the navel. \nhttp://www.straightdope.com/classics/a1_...\n\nMale nipples aren't exactly a genetic glitch: they are evidence of our developmental clock. In the early stages of life from conception until about 14 weeks, all human fetuses look the same, regardless of gender. At the tender age of 14 weeks post-fertilization , genetically-male fetuses begin to produce male hormones including testosterone. These hormones turn the androgynous fetus into a bouncing baby boy. \nHere's where the developmental clock comes in. By 14 weeks, when the hormones turn on, the nipples have already formed. So, while our male fetus goes on to become a baby boy, he keeps his nipples, reminding all of us that people, male and female, started off the same way. \nMale nipples aren't exactly a genetic glitch: they are evidence of our developmental clock.
