Penis Enlargement Surgery Is Risky--And There's Little Evidence That It Works

Penis Enlargement Surgery Is Risky--And There's Little Evidence That It Works

Penis size is a common body concern among men. While most guys report being satisfied with the size of their genitals, a sizable minority say they’re unhappy. For example, in a survey of 4,198 US men aged 18-65 who were asked to rate their satisfaction with 14 different aspects of their manhood [1], 85.9% were categorized as being satisfied overall. The remaining 14.1% (or about 1 in 7 men) were dissatisfied. Perhaps not surprisingly, their most common concerns revolved around flaccid and erect penis length as well as penile girth.

Are You a “Grower” or a “Shower?”: Average Penis Length Changes From Flaccid to Erect

Are You a “Grower” or a “Shower?”: Average Penis Length Changes From Flaccid to Erect

Some men’s penises seem to grow more than others when they change from a flaccid to erect state. In colloquial terms, men who experience a larger increase in length are often referred to as “growers”; by contrast, those who have a smaller length increase are often referred to as “showers.”

So what is the typical change in penis length from flaccid to erect—and just how many men fall into the category of grower versus shower anyway? A recent study published in the International Journal of Impotence Research offers some insight.

Fact Check: Are There Really Racial Differences In Penis Size?

Fact Check: Are There Really Racial Differences In Penis Size?

The question of whether there are racial differences in penis size is one that has been notoriously difficult to answer with any degree of scientific certainty. The problem has been that studies of penis size are usually fraught with problems. For one thing, there’s the question of who’s doing the measuring—the participant himself or a trained researcher? The concern, of course, is that guys will be generous when measuring themselves and/or will perform the measurements inconsistently. Then there’s the issue of participant selection effects—are men of a larger size more inclined to participate in such studies? In short (no pun intended), there’s reason to be cautious about drawing sweeping conclusions from the research in this area.

That said, recent studies support the idea that race-based differences in penis size may exist.

Yes, You Can Break Your Penis. And This Is The Most Common Way It Happens

Yes, You Can Break Your Penis. And This Is The Most Common Way It Happens

While erections are sometimes referred to as “boners,” the truth of the matter is that there aren't actually any bones in the human penis. Some animals do have penile bones, though. For instance, male walruses can have penis bones up to two feet in length! In fact, they are so big that they were supposedly once used as war clubs by Native Alaskans--but I digress. Returning to the human penis, you may be surprised to learn that, despite the absence of bones, it's still very much possible to “fracture” an erection. Here's what we know about "broken" penises.

Yes, Botox For Your Butt Is A Thing—But, No, It Doesn’t Cost $25,000

For the last two days, articles about “anal Botox” have been blowing up my Facebook and Twitter feeds, with most of the headlines (like this one from Cosmo) saying something along the lines of “Anal Botox Is A Thing, And Costs Up to $25,000.” To me, the surprising thing about these headlines wasn’t that people were putting Botox in their butts, but what they were supposedly paying for it.

The Fascinating Evolution of Animal Genitalia (Video)

The Fascinating Evolution of Animal Genitalia (Video)

Throughout the animal kingdom, genitals are very complex—way more complex than they are in humans. Take the male argonaut octopus, for example, which has a detachable penis that can swim on its own. Or consider female kangaroos, which have three vaginas and two uteruses each. On the surface, these genitals might seem way more complicated than they actually need to be for reproductive purposes. So why is that?

Inside The Growing World of Scrotal Enhancement

The number of men seeking to enhance the size of their penises is on the rise, with guys lining up to buy everything from pills to pumps to stretching devices to fat injections, all designed to give them extra inches in length and/or girth. My guess is that most of you reading this probably already knew that; however, what you might not have known is that men's interest in genital enhancement actually goes well beyond the penis. In fact, some guys are seeking procedures designed to change the appearance of their scrotums, too--for instance, by making them bigger or less wrinkly.

Do Men’s Penises Get Smaller As They Get Older?

A reader submitted the following question:

“I wonder, does the penis get any smaller with age? In other words, does the penis shrink as men get older?”

Thanks for this great question! If you try searching Google for the answer, you’ll quickly come across lots of articles saying that this does indeed occur—however, none of those articles actually cite any research to back up their claims. Instead, they rely on the opinions of physicians and other medical experts. That's all well and good, but I always like to have data. So, I did some digging.

Length vs Girth: Which Matters More to Women When it Comes to Penis Size?

Length vs Girth: Which Matters More to Women When it Comes to Penis Size?

Many sex researchers have surveyed heterosexual women about their preferences when it comes to penis size. Curiously, though, most of the studies out there have only focused on one dimension of penis size: length. So what do women think about penile circumference, perhaps known more commonly as "girth?" And is one of these two dimensions more important than the other?

Everything You Ever Wanted To Know About The Penis

Everything You Ever Wanted To Know About The Penis

 

Penile appearance varies widely throughout the animal kingdom. For instance, some penises have multiple heads (spiny anteaters), others are shaped like a corkscrew (lake ducks), and yet others are several times the length of the creature’s entire body (barnacles). Upon hearing about such incredible penile diversity, you might be tempted to conclude that the human penis is rather boring by comparison—but you’d be wrong. The human penis is still a pretty fascinating piece of anatomy in its own right.

Sex Question Friday: Can You Really Break Your Penis?

Sex Question Friday: Can You Really Break Your Penis?

A reader submitted the following question:

"I know there aren't any bones in the penis, but can you still break it, like if you bend it too much when you're erect?"

Thanks for this interesting question. To put it simply, the answer is yes. The technical term for this is “penile fracture” and it occurs when the cavernous bodies (i.e., the columns of erectile tissue that run the length of the penis and fill with blood during an erection) rupture as a result of some blunt force trauma. For instance, one of the most frequent causes of a fractured erection is forceful sexual intercourse in which a man misses his target and hits his partner’s pubic bone or perineum instead.
