Why do men have nipples?

Question

BobbieBoy666 · Accepted Answer

Men have nipples because Nipples develop in the womb before embryos develop a sex.
By the time a Y chromosome distinguishes a fetus as male, the nipples have already developed.
Nipples are also erogenous in around 50% of men, suggesting they may have evolved to serve a significant function in courtship and mating behavior, as well as promoting paternal engagement in child-rearing.

Men have nipples for a number of reasons, including:
Embryonic development
Nipples develop before sex chromosomes are defined, between weeks four and six of gestation. This is when mammary crests, or milk lines, extend between the armpit and groin. The remaining cells form the primitive nipples and areola smooth muscle.

Genetic correlation
Men and women share a genetic blueprint, and nipples are a genetic correlation that persists through lack of selection against them.

Erogenous function
Nipples are an erogenous zone for around half of men. The nipple-areola complex in men is densely innervated, which leads to frequent nipple erection.

Vestiges of fetal development
Nipples are remnants of fetal development, and it's not an evolutionary priority to get rid of them.

Summary. Males have nipples because of the way that embryos develop in the initial weeks after gestation. Those eventually born female and male are the same until sex chromosomes are defined, which doesn't happen until week six or seven of pregnancy. Nipples begin to develop before that time.

Human males and females actually all have the same body parts. During gestation in the womb, some body parts become specialized, based on sex. For example, female ovaries and male testicles are similar organs that perform specialized functions.

So here’s the thing: you’re almost right, 2/3 can be proven correct lol

All embryos start out as female in utero, and honestly there isn’t that much difference between a vagina and a penis in that embryonic growth production. The only thing that changes it to male is a series of lucky events (usually revolving around sperm count and how stressed/healthy the parents are). The female body will and has attacked male embryos as a foreign body before because it doesn’t fit with the rest of the mother’s body and are naturally weaker than female embryos, and if the conception has a stressed father with a lower sperm count, the female embryo will most likely win out over any male. It’s why you see men in high stress jobs such as the marines with nothing but daughters.

Also, men can breast feed! Truthfully, women and men both have the capability to make breast milk, there’s no real difference between a male and female chest under the skin aside from the fact that women’s are usually bigger. However, if you are a cisgender man and you start lactating, make sure to go visit a doctor as that’s likely a sign that you have breast cancer - something women get more often but can still effect men just as well. But if you’re interested in creating breast milk, it’s possible for you to do so as a man! It just involves a little hormone therapy.

In the early stages of fetal development, before sex differentiation occurs, all embryos develop the same basic structures, including nipples. It's only later in development, influenced by hormones, that the embryo develops into a male or female.

#1 - so that you know where the front is

#2 - so that you can annoy us by squeezing them

#3 - to make women feel better because 'ours' are small

#4 - temperature gauge... when they're hard, it's cold as fuck

#5 - to inspire questions (and answers) on GaG

Men have nipples because all embryos develop the same basic body plan initially, nipples form before sex hormones kick in to differentiate male/female traits. So biologically, they’re just a leftover from early development. No function, but also harmless. 🧬👀

The purpose of life is to reproduce. Sex is pleasurable because God WANTS us to multiply. The nipples cause arousal, hence leading to sexual desire, sexual desire leads to sex, sex = reproduction.

gays don’t reproduce unless they have heterosexual sex.

gays are not needed or else we would stop existing. To is is not to be “against” gays or “homophobia”, it’s a simple fact, like it or not, have feelings hurt or not, a fact is a fact.

I believe because all men were female as a fetus. No different than them having the seam line on their balls and up their shaft from where the vaginal sealed up in the womb.

Flower7 · Answer

Because in the womb, everyone starts out with a female form.

Tarifa · Answer

It's an evolutionary thing. A men's chest is the basic version. Women come with all the options.

An artifact of sexual differentiation during gestation. Also a work point for the lymphatic systems. And we want to give something to suck for training.

It's probably from ambiguous sexual dimorphism in early days of mammalian evolution.

HelpfulWoman · Answer

because we all start as female.  also men can actually induce lactation

Probably just for congruency. I suppose it’d be like if we didn’t have tongues like a shark or alligator.

All embryos develop nipples before the sex chromosomes are defined, which happens around six to seven weeks of pregnancy
