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. »
Cane toads were first released in Australia in 1935 as part of a government program to control the insects attacking the Queensland cane crop. It didn’t work. Ever since, the toads have been spreading across the country, as fast as they can breed. Which would be even faster, if it weren’t for an odd quirk in their… »
A couple of months ago, I helped out in Patricia Brennan’s lab when she made casts of dolphin vaginas. You heard me correctly. Dolphin vaginas. »
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.
This is the stickleback. The males of the species have a reputation for being wonderful fathers. They are so baby-crazy that if their nests are empty they will steal the eggs of other males, just to get a little something to watch over. But, wait! Just how did their nests become empty in the first place?
Sex should be fun, but for many people pain is not. Nevertheless, sex sometimes surprises us with a side of pain. It might be fleeting–from a lack of lubrication, an unexpected muscle cramp, some chafing or pinched skin, or it could be the result of a more serious medical condition. But whether it’s from shame or… »
Human vaginas don’t have the fantastical loops and blind alleys of a duck vagina, but they still have some pretty amazing shape-changing powers. Here’s how they’re put together, and how that anatomy lets them grow when they need to. »
Are you in a public place? Look around. Can you tell whether any of the women you see are ovulating, just by looking at them? Neither can anybody else. But several small studies have suggested that men nevertheless find women’s faces more attractive when they’re most fertile. No one knows what signals the men are… »
The first working model of the now-iconic birth control pill dispenser is in the Smithsonian’s history collection. It’s built out of clear plastic, paper, and double-sided tape, held together by a snap from a child’s toy, with slices of wooden dowel standing in for pills. It was created to solve a vexing problem. »
Sometime in the next two months, the FDA will vote on whether to approve flibanserin, a new drug to treat women with hypoactive sexual desire disorder, or lack of desire for sex. The drug has been touted as “female Viagra,” in the sense that it helps bring sex back into these women’s lives. But flibanserin doesn’t… »
The Age of Exploration brought Europeans riches, a broader view of the world, and a hell of a lot of new plants and animals to describe. That was heaven for Carl Linnaeus, a young Swedish doctor with a passion for plants. »
This is amazing. During the breeding season, American alligators call for mates with a deep loud roar. It’s preceded by a pulse of infrasound that sets the water dancing. »
Human testes are masters of mass production, spitting out sperm at a rate of 200 million per day. But that doesn’t mean the process is fast–it takes 64 days to make a sperm. The organ keeps the count high with an assembly-line anatomy that scales up sperm development from a trickle to a flood. »
If you like a bit of drama in your porn comics (and like to watch very short women getting it on with taller men), check out InCase’s webcomic Alfie. When a caravan of humans and elves visits a remote halfling village, two village women — a mother and daughter — find they’re in for some new sexual experiences. »
Charles Knowlton didn’t think much of the laws of Massachusetts, at least when they interfered with his medical practice. By the time he opened a practice in the town of Ashfield, he had already been arrested in Amherst, MA for selling “infidel” books and had spent two months in the Worcester County Jail for grave… »
Are you a woman with opinions about sex? For her doctoral work in Psychology at James Cook University, Hollie Baxter is running a survey to learn more about women’s attitudes about sexual relationships. If you’re a woman over the age of 18 of any sexual orientation, single or hooked up, she wants to hear from you. »
Southern dumpling squids (Euprymna tasmanica) are natives of shallow, sandy Australian sea beds, and their small, squat bodies and huge eyes combine to make them one of the most frickin-adorable animals on the planet. They spend their days hiding under the sand, but at night they’re tenacious lovers.
Earlier this month, an FDA advisory committee voted to recommend the approval of flibanserin, Sprout Pharmaceutical’s drug for women with persistently low sexual desire. The drug has a number of vocal critics, who believe that its side effects, relative to its modest effect, could be harmful for women. »
