This post was influenced by an 11 year old cousin who wants to be a medical doctor. She asked why I have nipples?. It was a weird question that got me thinking.


Brace yourselves for a low blow, tough guy. Nipples remind us that gender is anything but clear-cut, especially in utero. Whatever your sex, everyone starts off as a woman in the womb.
For the first several weeks a developing embryo follows a "female blueprint," from reproductive organs to nipples. Only after about 60 days does the hormone testosterone kick in (for those of us with a Y chromosome), changing the genetic activity of cells in the genitals and brain. But by then those mammary papillae aren't going anywhere.
So the real question is: why do male nipples come equipped with nerves and blood vessels? In many male mammals nipple Formation is stunted by hormones, but not in humans. Did prehistoric men nurse their young? The lack of evidence suggests not. More likely, full-grown nipples — being harmless
— don't get weeded out by natural selection.


The erection of nipples is not due to erectile tissue,
but due to the contraction of smooth muscle under
the control of the autonomic nervous system. It is
more akin to a hair follicle standing on end than to a sexual erection. Nipple erections are a product of
the pilomotor reflex which causes goose bumps.
The erection of the nipple is partially due to the
cylindrically arranged muscle cells found within it.

Nipple erection can also be caused by a tactile
response to cold temperature in both males and
females. Nipple erection may also result during
sexual arousal in females and males, or during
breastfeeding. Both are caused by the release of
oxytocin.

Nipples of both males and females are one of the
erogenous zones, which are generally stimulated by
hands or by mouth during pre-intimacy, which leads to
sexual arousal. The male and female breast have
a similar nerve supply but the nerves lie closer
together in men, whereas in a female breast they
are spread out more widely.[8] After puberty, female
breasts turn more sensitive, likely due to hormonal
influences. During arousal they generally become
stiff, erect and protrude.

Nipple stimulation is sometimes intense enough to
elicit an orgasm in some women. Research has
suggested the sensations are genital orgasms
caused by nipple stimulation, and may also be
directly linked to "the genital area of the brain".

In women, one study indicated that sensation
from the nipples travels to the same part of the
brain as sensations from the vagina, clitoris and
cervix. Nipple stimulation may trigger uterine
contractions, which then produce a sensation in the
genital area of the brain.

From conception until sexual differentiation, all
mammalian fetuses within the same species look
the same, regardless of sex. In humans, this lasts
for around 6 weeks, after which genetically-male
fetuses begin producing male hormones such as
testosterone.

Usually, males' nipples do not change much past this point; however, some males develop a condition known as gynecomastia, in which the fatty tissue around and under the nipple develops into something similar to a female breast.

This may happen whenever the testosterone level
drops. Gynecomastia, although not as severe, may
occur in pubescent boys undergoing physical
changes due to the rapid and uncontrolled release
of hormones, including estrogen. The heightened
levels of estrogen in pubescent male bodies leads to the swelling of the nipple and surrounding tissue – this can often look similar to a female human nipple
– and may cause slight discomfort. Thus, because
the "female template" is the default for humans, the
question is not why evolution has not selected
against male nipples, but why it would be
advantageous to select against male nipples to begin with.
