A couple of months ago, the Twitter hashtag #JunkOff got biologists to post photos that displayed the extravagant weirdness of plant and animal genitalia. Yesterday, evolutionary geneticist Tom Houslay dared them to write about what animals actually do with their junk.
One of the biggest challenges for scientists studying the anatomy and physiology of genitalia is the fact that much of the real functional action happens deep inside females. It’s hard to see what’s going on in there. That’s why I love studies that rise to the challenge of giving us a peek inside.
English is rich with clinical, silly, and sometimes filthy words for our naughty bits and the things we do with them. But when did words like "fart," "prick," "spunk," and "moon" enter the English language?
Depending on what era you live in, a penis might be known as a plough, a pillow prick, a jigglestick, or a jasper, while a vagina might be a fly-trap, an oracle, a catch 'em alive-o, or the antipodes. Brush up on your historical slang with a pair of genital charts.
This condition is one that you could guess if you really thought about the Latin name. Some men are born with two distinct penises. Although the condition is extremely rare, doctors know exactly why it occurs. Learn about this rare, but regular medical phenomenon.
Earlier this afternoon, Saturday Morning Breakfast Cereal's Zach Weiner floated an interesting thought: "One day," he mused, "there will actually be a pill that grows your penis six inches."
This is a wall engraving from Abri Castanet, a shallow cave in southern France's Vezere valley. It's the oldest known cave etching, probably dating back around 37,000 years—and the researchers claim it depicts female genitalia.
A recent historical survey reports that men who've undergone a penectomy will occasionally experience a phantom John Thomas, and it's usually not a painful experience. In fact, some men will experience phantom erections and illusory ejaculation. What a silver lining!
If there's one thing a rabbit needs, it's well-functioning genitalia. Scientists have successfully regrown rabbits' damaged penises, letting these rabbits do what rabbits do best. And their research could have important implications for generating human tissues as well.
