Why is it that men have nipples?

Answer 1

Males and females are different from the day of conception. All females have two X chromosomes (easy to remember; they were all double crossed?). All males have one X and one Y chromosome. Initially all fetuses have primary and secondary sex features that can develope into either a male or a female but the higher levels of male hormones in the male fetuses (with X and Y chromosomes!) causes male development. At birth the difference is obvious. At puberty when there is another hormonal upheaval the differences become even more prounounced as the "wiring" initiated in the fetus is completed. Males grow facial hair, voices deepen and torsos taper. Females soon qualify for Playboy Magazine, etc. with shaply (36-24-36) figures. Both males and females have the same hormones; but significant differences in their concentrations drive the proper developments. Hope that helps a little.

Answer 2

Because by default, all embryo's start out with all the genetic information to be female which includes having nipples for child-rearing.

It's the Y chromosome that alters the physiology and development of an embryo by telling the cell when to produce masculinizing hormones at the proper times to change the embryo into a male.

Answer 3

The basic cell starts as female and after fertilization, 6 weeks, the Y chromosome kicks in en tells the cell to change and become male. So the nipples stay. Even the brain wiring changes. Sometimes things go haywire, depending on the condition of the mother and tragic crippled boys are born.
The original eukaryote cell was female.

Answer 4

Because it is in God's final plan to make men start having children and breat feeding, that is if you did not obey the 11 commandments.

Yes 11.
The 11th one is
-Thou shalt not laugh at larry The Cable Guy!

Answer 5

Except for the reproductive organs, girls and boys are same at birth.Later on at puberty when the hormones are secreted it starts different developments in both, causing the breast of women to grow but not of men.

Answer 6

Because when God created Adam he gave him nipples

Answer 7

Men are originally women while they are in the womb. Later, the chromosomes make the female fetus males.

Answer 8

Because females are the prototype for the species. Before the male fetus is flooded with testosterone during development, it is essentially female, and basic female structures develop.

Answer 9

definite, my gf's husband became into fairly obese and had to be positioned on Viagra to develop his testosterone through fact he began to offer milk. i assume someway his hormone stages tousled through surplus weight. It became into fairly discussing on the time through fact his shirts would be observed. Now if that is suited for slightly one or whatnot I have not got any clue. I doubt that a healthful guy would be waiting to offer milk nevertheless. and for people who did no longer pay interest in biology ~ women folk and adult men persons the two have testosterone and estrogen. that is in basic terms adult men are assume to have lots extra testosterone then women persons and girls persons extra estrogen then adult men. examine out a GNC save sometime.... interior the mens area they have "estrogen blockers" for physique developers :)

Answer 10

Not sure. Also not sure of why men have external genitalia. Or back, nose, and ear hair. Poor design....
