in some cases, men should wear bras.  I've seen some big men out there and they have bigger boobs than me and I'm a girl...it's sad..but true...did you know some men do wear bras? I know one and it's more like a bra to hold the fat in so it doesn't show as well as helping with medical reasons like back problems...

All human embryos in the womb look the same externally, until testosterone is either added or not.  If not, the baby will develop physically as a girl, if the testosterone is added, the baby develops physically as a boy.  This is true regardless of the XX or XY chromosome of the baby.  The nipples develop prior to the addition of the testosterone.\n\nThey are there because the child could have developed as a woman, and the only purpose that I can think of that they have for men is perhaps a little thrill when your lover pinches them. :)

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\nAs you may know, every human being gets a unique set of 23 pairs of chromosomes at conception. These fall into two categories. One pair of chromosomes determines sex--the XX combination means you become female, the XY combination means you become male. \n\nThe other 22 pairs, the non-sex chromosomes (they're called autosomes), supply what we might call the standard equipment that all humans get. These 22 pairs constitute an all-purpose genetic blueprint that in effect is programmed for either maleness or femaleness by the sex chromosomes. The programming is done by the hormones secreted by the sex glands. \n\nFor example, the autosomes give you a voice box, while the sex hormones determine whether it's going to be a deep male voice or a high female voice. Similarly, the autosomes give you nipples, and the sex hormones determine whether said nipples are going to be functioning (in females) or not (in males).\n\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.\n\nIt's tempting, therefore, to say that male nipples are yet another vestige of your carefree bisexual youth. Trouble is, male nipples are hardly vestigial. They're full-sized and fully equipped with blood vessels, nerves, and all the usual appurtenances of functioning organs. Why this should be so nobody knows--in some other mammals, such as rats and mice, male nipple development is completely suppressed by the male sex hormones. (Incidentally, don't start thinking that at one time our human male ancestors must have suckled their young. So far as anybody knows, male lactation has never developed in any mammalian species.)\n\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. \n\nNormally only one pair amounts to anything, but on about one baby in a hundred you can detect some vestige of the other ones, usually on the order of a freckle. There are cases of women who ended up with an extra breast, which made them freak show candidates not so many years ago. Luckily today the women can avail themselves of corrective surgery while the rest of us can watch Jenny Jones.\n\nAnyway, both male and female babies are born with the main milk ducts intact--the gland that produces milk is there in the male, but it remains undeveloped unless stimulated by the female hormone, estrogen. Occasionally, a male baby is born with enough of his mother's estrogen in his body to produce a bizarre phenomenon known as "witches' milk," with the male glands, suitably stimulated, pumping away at the moment of birth. \n\nIn the adult male, the dormant glands can still be revived by a sufficient dose of estrogen. Actual lactation is rare--only a couple cases have been recorded. But at least one writer (Daly, 1978) has suggested that the "physiological impediments to the evolution of male lactation do not seem individually surmountable." Meaning we may yet see the dawn of the truly liberated household.

Yes Male lactation is possible because men also have mammary glands. given the right hormones, these glands activate, and the person may lactate.\n\nThis is more common in men undergoing hormonal treatments (such as for prostate cancer), because female hormones are used to retard the cancer.

Why Men Have Nipples\n\nFor the most part, nipples are on men's chests not for ornamentation, but because we all initially originate from the same kinds of tissues. By Louanne Cole Weston, PhD\n  \n\nMales and females, though very different, have a great deal in common. In the earliest part of our embryonic development, we all start out much the same. Though the sex of an embryo is determined when sperm meets egg, the genital anatomy of males and females cannot be visually distinguished with the use of ultrasound until the 15th week of pregnancy. \n\n\nFrom the beginning, we all have the tissues that later develop into functioning parts, depending on whether we are genetically coded to be male or female. (The genetic coding that leads to people who have both male and female anatomical traits is much more complex than we'll get into here.) \n\n\nMales have nipples because they develop with the capacity to be female should their chromosomes dictate. Females call upon this capacity when they hit puberty and their breasts develop. Later, if they become pregnant, they call upon it again as milk is created in their breasts. Generally, males do not have a reason for the nipple to function, although, from time to time, adolescent and adult males develop a condition called gynecomastia, in which hormonal levels fool the breasts into beginning to develop. \n\n\nBut for the most part, nipples are on men's chests not for ornamentation, but because we all initially originate from the same kinds of tissues. Males just don't need their breast tissue to be a functioning part of their anatomy

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.

yeah...i do...i'm a size 36DD and i love my breasts...but men dig them more. The are nice and suckable, the nipples that is!

first, human male nipples are not useless, nor are they "vestigial" (more about "use" in a moment)\n\nto answer the latter part of your question...yes!\n\nmales actually can lactate under certain conditions (stress, medicinal/hormonal stimulation, and others); males do have, unbeknown to many, mammary glands\n\nbut male lactation is an unusual, rare event\n\nand human males would not be able to produce the quantities of milk needed to adequately nurse offspring\n\nthe primary purpose of the human male nipple is to serve as an erotic stimulus\n\nthe very first command that god gave to man and woman (adam and eve) was reproduce and fill the earth (ie, have sex and make babies)\n\n(of course the sexual relationship was always and only intended to be addressed within the marriage relationship...on the other hand, neither was it intended to be limited to some simple act of nothing more than making babies; it was also intended for pleasure according to the "song of songs"\n\nin the physically fit male, which men were originally intended to be, the nipples serve to sexually stimulate the female when they gaze at their husbands while working or relaxing; they also serve to sexually stimulate the male when his wife offers manual or oral stimulation\n\nin short, the primary function of male nipples is to serve as an erogenous zone (through visual and/or tactile stimulation)

Breasts or mind...Hummmm Why limit your self to that?There are plenty of women out there with both.Just don't over look a good heart also.For a cold hearted idiot...Breasts are just a place to hang nipples.If you are looking for a woman solely for breasts.You are going to end up  disappointed.If you find a woman with heart and brains.You will love her breasts,of any size.

Your breasts are made of fat, skin, muscle and milk ducts, and other assorted things (like tubes to connect your milk ducts to your nipple, blood vessles, lymph nodes, etc)\n\nIn fact a male breast is made up of the same thing.\n\nMale and female babies can be born lactating because they are exposed to their moms hormones.\n\nSo you do not have breastmilk in your breasts but you are capable of making it if your hormones tell you to.

Because in the womb, we develop equally until a certain point where our respective genders become more apparent. The period before this is when men grow nipples.\n\nBesides, can you imagine life without your nipples? A bleak world indeed.

The reason is a mix of physiological responses. However primarily the nipple's purpose is to provide milk to a potential infant. So, following this line of thought one can speculate that even if you were to consider it an erotic response, underneath it all it is just a physiological reaction to allow a potential infant to find its source of food. Crazy isn't it? Also here's something I found from Wikipedia.org - \n\n"Stimulation or sexual arousal can cause the nipples to become erect. Breastfeeding or exposure to cold temperatures often have this effect as well. Pregnancy and nursing tend to increase nipple size somewhat, and this increase may remain permanently thereafter. Small non-striated myocytes (muscle cells) arranged cylindrically within the nipple are responsible for this erection of the nipples."

nopes...they dont have vaginas. homosexuality is an attitude, a personal preferance. it has nothing to do with physical abnormality or anatomy.

Breasts were declared sexual by nature. By nature a man is attracted to breasts. Even in African cultures, the men are indeed attracted to breasts. They just have no great urgency to view them, since they are constantly exposed.\n\nThough I hate to go into great details about sex, breasts are considered sexual by phenomina. Woman's breast are effected by sex. A woman's nipples often errect durring sexual arrousal. Also, (if I'm not mistaken) estrogen, the same hormone accounted for much of the physical, sexual, emotional, and reproductive stages and changes of women, also determines the size of a woman's breast. Thus, proving that breast are linked to a woman's sexuality. \n\nAllowing women to roam topless would only degrate women and girls. It would support the notion of treating and handling a woman's body as a man's. If women's breast are to be declared "nonsexual", than the groaping of a woman's breast can not, by definition, be considered a sexual offence. Touching a woman's breast would, legally, be no more offensive than touching a woman's shoulder. Though touching a woman's shoulder can be viewed as sexually offensive, it can only be considered so if with intent, (which can be difficult to prove).\n\nImagine a society where 12-17 years old girls are allowed to expose their breasts in public. Pedaphiles would be allowed to view topless yound girls without legal endangerment. Imagine a society where men can just ask a woman or girl to remove her top without legal offense. Imaging shcools, with sexually raging young boys/men, requiring girls to be on the "no shirt" team, durring 2-hand-touch.\n\nI do believe in treating woman with respect. However, there are, without a doubt, differences between men and women. Ignoring these diffences can prove to be degrading and underminding for both sexes. It could also prove to be dangerous for women. Though you may think otherwise, you would not want society to treat a woman's body as a man's.

Males also have the hormone estrogen. Estrogen menlarges breast size. Women have more of it, so they have bigger breasts. They also have luteniezing hormone which produces milk for mammary glans after giving birth. Men do not have that. Women displaying male qualities like beards have an excess of testoserone and androgen

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.
