Why do males have nipples?

[blahblah99]

Cause evolution forgot to remove them.

 

[SSSnail]

What I want to know is, why don't females have tits on their back? Keep the front ones too.

Reminds me of the time I answered the door and their were two woman in their 30's to late 40's not wearing any shirts.Seriously they were both topless.
They wanted me to sign a petition that would allow women to walk around without shirts because guys can do it, they didn't think it was fair. The SO did not appreciate my enthusiasm for signing.

Fail - look into fetal development, cell replication, roles of hormones, DNA, whatever, on and on and on.

I'm not quite sure I follow.

Are you saying its intelligent that all fetuses start out as female? Wouldn't it be more intelligent if they were different?

In case of emergencies

I'm a guy, and I'm not afraid to say that sometimes when the woman is gone I like to cuddle up with some Scotch and just give 'em a good twist for a few hours.

 

[theeedude]

Because women didn't select men with smallest nipples when picking a mate, and predators/diseases did not select for man with biggest nipples when picking their next meal.

To really understand this conundrum, you need to go way, WAY back to conception...where we ALL ARE "BORN" as females. Really. Take it from there...testes/ovaries and all.

Not "born" as female, but female characteristics are the default pathway. This has nothing to do with nipples though. The gene controlling nipple formation is not linked to a sex chromosome, and thus men and women both have nipples. Sex hormones, like estrogen, progesterone, and prolactin (milk-producing hormone from the pituitary) are what cause breast tissue to grow.

But it IS all about the nipples. If I'm not going to suckle my baby, why do I need nipples? Why not during the formation process (after my sex has been determined) do my nipples not fade away? My testicles used to be ovaries, my nipples were supposed to become breasts (bigguns...not my manly guns...) so why not?

Anyway, I'm glad I'm male. I'm not subject to the monthly insanity/loss of mental function like my wife.
/looks over shoulder

Oh shit...I think she hears me typing...she'll fucking kill me if she reads this...gotta go....teh womenz is teh SCHAIRIIIIZ at that time of teh montheszzzz!!!

again, sex is already determined at conception. once that sperm hits egg, you're either XX or XY (....or in rare cases....XXY or XXX or XYY). The embryo develops along eh same pathway, however, for a certain period of time. The penis develops as if it was a clitoris, sex organs begin as generic sex organs, etc.

Hell, we all have gills before the lungs show up, so when does the "not-a-fish" gene kick-in?

nipples don't fade away because they don't need to. Having nipples as a male doesn't make you any less viable as an individual of the species, so we have never been naturally selected to be nipple-less.

But the "mission of the nipples" (breastfeeding a baby) is not realized in the male of the human species. I'm not "that smart" but am I not correct? So...why do I have nipples?

like he said: it hasn't been detrimental in such a way as to have been selected against.

We still have an appendix. It doesn't do anything, but it's still there....

Why do women have Voices?



We will never know....

nope. We are male or female at conception.

The early stages of development, however, is as if we were all female.

Think about it: the sperm that fertilizes the egg either carries an X or a Y. Once fertilization happens, the embryo is already sex-determined. When else would you posit that a chromosome gets introduced into the embryo?

what are you, a turtle? Holy hell, a typing turtle that can log-in to the internets!!! :Q

because there would be no reproduction ever again.

A male on hormones can lactate though...the nipples are functional. Males just don't produce the proper hormones to create milk.

Well unless you simply don't believe in evolution, it should be easy to realize that it's still easily said to be rooted in evolution. Males only are that way in the womb because well... that's how mammalian life came to be. A different evolutionary path could have resulted in something quite different.

It's easy to look at everything here in the present today with wonder, amazement, or curiosity, and far too easy to take everything for granted. We're at the end game of a complex system that gave way to some of the strangest creatures, and then took that life away in favor of other life, while others fought and stuck around for the ages. Everything might seem perfect now, and all answers seemingly easily given because of what we know about how life currently operates, but how it got here, and why here and not something else... that's where an answer to something seemingly as simple as nipples will truly be found, aka never to be known.

And as you were stating, male and female develop in the same body style, sexual identity by way of sex-specific genetic material doesn't even develop until a specific period in the cycle. Meaning: we develop as a unisex prior to becoming whatever sex was determined at conception, because those sex-specific genetics don't even have a play in the development of life until the rest of the genetic material can shape cells into the base structure on which the sex-specific code can manipulate.

So, back to the root: why are nipples included in the base, unisex human genetic material, and not included only in the female-specific coding, thus never developing in the base structure until the sex-specific genetic material begins to change the fetus ?

See how I got there? Right there is the true question, and as I offered earlier, the best theory would be that at some point far back in time, some of the first mammals, the way they happened to have been coded was with nipples in the unisex/common genetic material. Some mammals may have had it sex-specific, but apparently they never made it, or the random mutation of nipples, with coding being unisex, just happened to have occurred first, and worked. It produced unnecessary nipples in males, but in the end it worked, and through no means did the males have any problems, and thus, they survived, mated, and the offspring lived. Thus, that coding stuck. And through the ages, it stuck, because it just worked. Sex-specific could have just as easily worked in the end, but through whatever random natural occurrences, that was never given a chance.

Sounds like a plan, but I'd get some more science research in first if you are going to formalize arguments on the subject.

I can't even begin to think of what the hell you are talking about. I quite clearly say Sexual Differentiation, so it can't be you accusing me of saying we are all the same from species to species (even though, funny enough if you look at the embryos of most organisms they are extremely similar especially within class).

 

[Poulsonator]

Because it feels damn good to have them rubbed on and sucked on by the ladies. I love having nipples.

 

[RichUK]

They?re part of the human body?s early warning system for when it get?s too cold.

STIFF NIPS MUCH?

Yeah, but... that requires work. And, I'd require payment for said work.

Otherwise I'd completely agree and follow through with the suggestion.

Apparently in many cities in Oregon this is legal.
I lived in Eugene for a while and never once saw a bare chest outside a strip club. It seems that where its legal people dont excercise it.
