Help answer this question below.
Because embrionic development works that way. The gender is decided later than the first stages of embryo development. It's like this in all mammals.
well they still have an x chromosome in their DNA so they get a little bit of the female genes too, you know.
also there is a condition called gynecomastia, which makes a man produce more breast tissue & gives the appearance of a more female-like chest.
So that if they become pro wrestlers... they can flex / jiggle them to show how tuff they are.
i beleive its a warning to men that they are becomming obese
Only fat men have breasts, & they're called Moobs!
So if they can't get to second base with a female, they can try it on themselves...?
lol, nah. I think it has something to do with the fact that gender is decided after the nipples hav formed.
i think its pretty nasty for a guy to have "man boobs"
Mitties are NOT hot.
(so guys with Mitts, hit the gym!)
as we have decended from females and evolution hasnt effected it
Its a necessary muscle and to we use it to attract women.
God is too lazy when it comes to genetic design.
to expand
In case they need a sex change later on.
A man does not have breasts...ever! Its called a chest or pectorals..Unless you are overweight then you just have a fatty chest.
males arent supposed to have breats but if they get really fat then breast tissue can develop
All fetuses start out as females, then (some) change to males during embryonic development. All males have breast tissue (males can get breast cancer too), it's just not usually as developed as the breast tissue of females. Functionally speaking though, male breast tissue serves no purpose; it just simply hasn't proven detrimental enough for evolution to get rid of it.
Regarding pectoral muscle (which some people consider part of the breast, although I have no idea why), both sexes have this too, although in males it tends to be more prominent.
