Of all the things that are different between men and women, it's the weird biological differences that are arguably the most fascinating. Unlike social or psychological differences, which can be influenced by outside forces, male and female differences based only in biology (with a hat tip to evolution) highlight the traits that make male and female homo sapiens truly unique in the animal kingdom. We're a weird pack of hairless apes, it turns out.A look at the the objective, biological differences between male and female bodies reveals that men have larger brains, hearts, and feet, but have an inferior sense of smell, sight, and taste. Women have a harder time dealing with the cold and cry more, but men are more likely to suffer a heart attack or skin cancer. That's just scratching the surface: here's a look at the weirdest biological differences between the sexes.
Women Have an Organ Devoted Solely to Sexual Pleasure
There's only one human organ dedicated 100% to sexual pleasure, and only women have it: the clitoris! Sure, men have plenty of pleasure points down there, but they are all meant to do other stuff, such as boring old reproduction. Unlike any part of male genitalia, the clitoris exists only to give women sexual satisfaction.
The Clitoris Grows with Age, the Penis Doesn't
Call it Clitoris Envy: unlike the penis, which stops growing when a man is between 13 and 18 years old, the clitoris continues to grow well into adulthood! In fact, when a woman is 32, her clitoris is four times larger than it was at puberty. The clitoris exists only for sexual pleasure, so a woman's body is wired to be more receptive to such pleasure the older she gets.
Men Are More Tolerant of the Cold
In the middle of a thermostat war with your spouse? Know this: a woman's mean body temperature is slightly warmer than a man's, but a woman's hands and feet are, on average, much colder. Why? One theory is that body fat (which women have more of) keeps their organs and important reproductive parts warm, but at the expense of their chilly fingers and toes. There are other factors to consider, but on average it's true that women have less tolerance for cold temperatures than men. So have some sympathy, guys!
Women Have a Better Sense of Smell
No one knows why, but women are born with more olfactory bulb cells than men (43% more!), meaning they are pre-wired to have a superior sense of smell. Scientists think this skill may have something to do with reproductive behavior such as kin recognition (i.e., helping to avoid inbreeding in the early days of humanity).
