Why do men have nipples...

[hellabell]

What is the point in men having nipples if they can't take a turn at the 1am feed? (or the 3am, or 4.12, or 5.36)?? Were they involved with breast-feeding at some point in our evolutionary history, perhaps until the point that mother nature realised they couldn't even WAKE UP in the middle of the night whilst someone else was doing the feeding, changing, and settling down?

i think they have nipples because ta some point all fetus' are female....

i may be VERY wrong though

Do you feed lying down i nbed? much easier IMO

All embryos start off female I think and thats why men have nipples.

No, all fetuses are not female at some point - the boys are XY from conception. All fetuses may be indistinguishable at some point, but at that point they have neither male nor female sexual characteristics.

I don't know why men have nipples, though. Probably because the two halves of the same species can only be so different while sharing the same DNA.

Because it cost too much to take them off?

Actually all the male animals have nipples so it must have some relevance/meaning

If they are injected with prolactin, they can lactate with the best of us!

Female is the blueprint of the human being though as proven by the X chromosome. We are XX they are XY

there is a theory that says the evolutionary purpose was to allow men to comfort a child in the absence of its mother.
men can lactate though I have never seen it

A foetus is genetically male or female from the point of conception (there are people with different sex chromosomes but for brevity I'm leaving them out of the description)

If a male foetus doesn't get 3 'doses' of testosterone during development (which it produces itself, from a gene on the Y chromosome) it will develop the external genetalia of a female.

Nipples start to develop early on.

Harpsichorcarrier :I like that idea - men were the original dummies.... do also like the idea of them being able to lactate. Well actually idea is vile, but I could turn a blind eye in the middle of the night. As he sleeps through everything anyway, might try getting baby to latch onto him tonight.... cruel to baby, but oh how I'll laugh if he wakes up with boobs...

I have looked this up before, It is beacuse all babes start as female in the womb, All humans begin life in the womb as females. If no Y chromosome is present in the foetus, then the embryo will continue to develop as and be born as a female. If there is a Y chromosome present in the embryo, the male sex hormone testosterone restricts the full development of breasts to just nippl

foetuses are either genetically male or female (genotype). They start off with the physical characteristics of a female (phenotype).

This phenotype changes to that of a male once he has been expesed to testosterone.

Phenotype = genotype + environment

harpsi - i heard on the radio the other day that there is a tribe somewhere in Africa where the men look after the babies when they wake in the night and let them suck on their nipples for comfort while the women go out hunting. Seems like a good system to me. Although I don't fancy night time hunting so much.

tis possible

Have decided this is now quite a serious issue! If they actually CAN lactate, how the hell have they managed to dodge doing it for the past millenium? Did they just give up??

and why do some men find nipples being sucked sexually stimul;ating and some not at all?
