I live alone and have never had a baby. What's your real question? Just asking.
Male sea horses give birth to babies, too.
Having two sexes is the best method for evolutionary success. Male and female is continued in every animal species higher than slime mold. Even many plants have male and female separation.
Men don't have orifice big enough for a baby to come out of. All births would need to be c-sections. Too much risk, too complicated.
Because medicine hasn't come far enough yet to allow men to give birth.
men would cut corners..do half of it now..finish up later
or how men are physically stronger than women..everythings designed
because men ar cry babies and couldnt handle it:p lol
Science is working in the other direction too.
Men do all the other hard stuff like... ummm... yeah.
I was a test tube baby. :(
