How long will it be before men are born without nipples?

Answer 1

As the male gene/s responsible for nipple development & retention in the womb are found in the entire population of men in the world, it would be highly unlikely that men would ever lose these genes.
For males as a whole to lose their nipples in the future, a mutation would have to occur in the genes of an individual, resulting in either a lack of nipple development entirely or a loss of nipples in the womb.
This individual would then have to pass these genes onto his offspring, resulting in a few different possibilities.

1) If having no nipples resulted in worse 'fitness' (lower chance of having children, fewer children, children with poor chances of reproducing) then it is likely that the mutation would die-out.
2) If the nipples resulted in better fitness, it is possible that over the course of many generations that the genes for nipplelessness would replace the genes that are in the population today, resulting in all men having no nipples.
3) If having no nipples neither helped nor hindered the individual's fitness, it is highly likely that the genes for nipplelessness would be lost, given that the odds of it being lost are high. His offspring would have a 50% chance of losing the mutation with each generation. Although it is highly unlikely, it is possible via genetic drift for the mutation to spread and persist in the entire population over a course of many generations.

In summary, given what we know about genetics and the function of nipples in males, it is mathematically unlikely that men will ever lose their nipples over the course of human history.

Answer 2

Probably never unless there is some reason why men with nipples have less children than men who retain them. Evolution has no direction, it is just the survival of the fittest and traits with no consequence tend to persist.

Answer 3

Why do ask? Nipples are an important part in a man's life (it makes any chest muscles look bigger). So as a man I hope tht it will never happen

Answer 4

All foetuses start off female and have the capacity for nurturing their offspring. Thats why men have nipples and it will probably never change.

Answer 5

"Do you understand what the heck I'm saying? " Yeah it is utter nonsense, here is why. 1) Not all inborn traits are genetic. 2) Even it that was not true the statement "You see and if you were born gay then if you had sex with the opposite gender before you were gay then your kid would be bi" implies that your genetics are effected by the choice of your parents, which is of course utter bollocks. 3) "Or are you to much interested in learning that it is bad that I had to type all this long... mind am I right?" Does even even understand WTF he just stated? Or is this simply an attempt to show he as failed English?

Answer 6

never because the sexes are developed in womb and the nipples are part of the development process

Answer 7

men will always have nipples because women will always have nipples and we get half our genes from our mother.

Answer 8

i know a girl with 3 nipples?!!?

Answer 9

However long it takes for women to be born without pubic hairs.

Answer 10

men will always have nipples
