The Biology Of Sex

7 Things You Never Knew About The Biology Of Sex


As the single most important act for the survival of our species, you’d think sex would be easier. Most of the time, it’s a simple guessing game of figuring out what goes where, but anything more complicated than that lurks like a hideously promiscuous elephant on a slippery slope of darkness and contrition. The truth is, for something we’ve been doing since the dawn of time, we just don’t know much about sex—but we’re learning. And we’re doing it the only way we know how—in a sterile lab, in front of scientists.

1. Human Penile Spines.

Penile spines, as you may know, are spines on the penis. Plenty of animals have them, from the humble field mouse to the proud buffy-tufted marmoset. They’re usually used to rake the inner walls of a female’s vagina after sex to induce ovulation or to prevent the female from mating with anyone else. As it turns out, humans have the genetic coding to create penile spines, too—at some point, we had prickly pickles just like everyone else in nature.

2. High-Pitched Voices.

If you were asked to form a mental image of masculinity, what would you picture? Muscles? Beards? Deep Mufasa-esque voices echoing through the canyons of your own insecurity? According to research, most women feel the same way about what constitutes manliness, and those are the type of men most women look for in a mate. A deep voice is inextricably linked to higher testosterone levels, which is further associated with genetic strength—big men make better baby daddies.

3. Sexual Genetics.

Most people picture the Stone Age as a rampaging sex frenzy peppered with raucous interbreeding between Neanderthals and Homo Everythings, the kind from which you wake up three million years later with a pounding headache and an acute sense of regret. While it’s true that Homo sapiens and Neanderthals had some liaisons between the sheets, it didn’t happen nearly as often as we once thought. Spicy or not, the study of ancient sex is giving us something else: clues to the movements of early humanity.

4. Boosts Immune System.

When you get a cold, your first reaction probably isn’t to kick yourself for not having more sex. From a physical standpoint, sex is healthy for you—after all, it’s just another form of exercise—but it also benefits you at the cellular level by raising levels of igA, an antibody found in your mucus that kills cold germs. In most cases, igA is a good indicator of immune system health—the more igA you have, the stronger your immune system is.

5. Hot Women And Health.

When you do something dangerous, like skydiving, your body pumps out massively increased levels of a stress hormone called cortisol. Cortisol is the primary hormone in the “fight or flight” response that floods your system with adrenaline and primes your body for survival. Put an attractive woman in a room with a man, however, and that man’s body suddenly can’t tell the difference between a nice set of legs and a rampaging bear.

6. Transient Global Amnesia.

Transient global amnesia is a condition in which a person’s memory randomly disappears for a short amount of time. It happens suddenly and usually it goes away after only a few hours—but during that time, you can’t remember anything past a certain point. It also affects your ability to make new memories, so you’re constantly living inside a window of just a few seconds between doing something and forgetting about it. It’s like Memento, but without all the tattoos.

7.Orgasmic Exercise.

Getting to the gym is hard for a lot of people. It’s a commitment, and one that comes at the expense of other, more enjoyable things—like virtually anything else. But for 5 percent of women, there might be a new reason to start working out: exercise-induced orgasms. It’s exactly what it sounds like—women have reported reaching climax simply from working out. The phenomenon was first mentioned in 1953 during an unrelated sex study by Dr. Alfred Kinsey, who said that a small percentage of the 6,000 women he interviewed voluntarily mentioned that sometimes their workouts came with some extra motivation.
