Some mammals have a dangerous-looking penis because their glans is covered in spines. In a few cases, we know why they’re there (typically, to induce ovulation during copulation). But in many other species, the purpose of the spiky bits is something of a mystery. »
Previous studies of how women perceive penis size and shape relied on 2D drawings and photographs of flaccid penises. Now, a research team of psychologists from UCLA and the University of New Mexico have taken things into the third dimension. »
Female mosquitofish give birth to tiny babies, like the guppies you may remember from your third-grade aquarium. That means male mosquitofish don’t spawn: if they’re going to be dads, they need to use a modified fin (called a gonopodium) to inseminate their mate. And sex with a long, stiff fin demands a daunting level… »
Guys, imagine for a moment what life would be like if you couldn’t feel your penis. That can happen to men with some kinds of spinal injuries, or who were born with a condition called spina bifida. Their penises can still sense touch, but a break in the spinal cord means the signal never makes it to the brain.
If you’ve ever watched a pair of dogs have sex, you’ve probably noticed something odd happen partway through the act. At first, the male grips the female’s back and humps away–nothing unusual about it. But then he dismounts and turns to face away from his mate, with his penis still stuck inside her. »
We’ve seen it in study after study: men worry about what their penis looks like. Is it too short? Too long? Too thin? Is the glans too fat? Will that birthmark be a deal breaker? Relax. A study published in the Journal of Sexual Medicine last month suggests that women don’t really notice those details.
Sea slugs are beautiful, jewel-like animals with surprisingly violent mating habits. This tiny unnamed species in the genus Siphopteron is no different. »
Erectile dysfunction isn’t a new problem, but there weren’t any effective treatments for the condition until the middle of the 20th century. Before then, desperate people turned to sympathetic magic, patent medicines, fad treatments, and convincing frauds to try to get it up. »
You already know that a penis has arteries to bring blood to its erectile tissues, and veins that take the blood away again when it returns to its normal flaccid state. You may not know that there’s another set of vessels tucked under its skin. We just got our first good look at them. »
Until the early 1970s, if problems with penile blood flow or nerve function meant a guy couldn’t get it up, his choices for treatment were pretty limited, and certainly did not mimic nature. »
Her Majesty Queen Elizabeth II is showing the world sketches of penises and vulvas. Admittedly, they’re penises and vulvas that Leonardo da Vinci drew around 1508, which makes them art instead of crotch shots. Check ‘em out at the oh-so-proper Royal Collection Trust website. »
Like our brains, the human penis hasn’t evolved in tens of thousands of years — and that’s a real shame. Our favorite male body part is capable of so much more. In consideration of pending advances in science and technology, here’s what to expect with penis 2.0.
Your spam folder is probably full of the offers. (Mine certainly is.) But none of the emails promising to let you “please your partner” by making you a “giant for girls” with “strong erections” say a thing about how the penis gets erect in the first place. Here’s how it really works. »
You may have noticed some news around these weird sounding devices that measure “arousal”. They don’t. But they do measure changes in penile shape, and as such, can give users a rough estimate – in a non-invasive way – of how much blood is flowing into the penis during erection. »
You know that excited, blissful feeling on Christmas morning? When you scramble downstairs with a bounce in your step and a sparkle in your eye? And then you hunker under the tree to greedily unwrap your new penis-shaped Play-Doh dispenser? Because after this holiday season, a whole bunch of kids and parents do. And… »
It's man's most-pondered question: Does size matter? While there are social and scientific explanations of the varying size of male genitalia, I feel as though none of them truly answer the question for the individual. They seem rather to quell the ongoing question only temporarily, but without an answer you can take… »
