Not one, not two, but four pelvic floor exercise devices are hitting the market to encourage women to do their Kegels. Rose Eleveth talks to their creators about their mission to help strengthen hidden (but important) muscles and asks whether the process really needs to be gamified. Check out the article at Refinery… »
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. »
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. »
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. »
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. »
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. »
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. »
It’s normal for a penis to curve a little when it’s erect, but Peyronie’s disease pushes that curve to alarming extremes. It doesn’t usually muck with a guy’s ability to get it up, but once the penis is erect, it can deviate 30° or more from its normal line of action. The curvature can be so severe it interferes with… »
In this TED-Ed episode, we hear in delightfully morbid detail how the ancient Egyptians mummified their dead. Drain the brain, bottle the organs, salt the body and entomb for thousands of years. Simple as that! »
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. »
Sexual selection doesn’t necessarily just shape sexual anatomy – it can have as profound an effect on the rest of an animal’s body as natural selection does. In both cases, the end result is more babies for animals that look or act a particular way. »
When I was in graduate school, I wondered what changes made erectile tissue in the penis shift from its soft and flexible state to its stiff and inextensible state. Then, with the help of some armadillos, I did the research and figured it out. Tell me what you wonder about, and I’ll see whether I can figure it out for… »
People have always wondered about sex, and as literacy became more widespread over the course of the seventeenth century in England, books appeared to feed that curiosity.
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. »
That dopey face your cat makes—its mouth half-open, its lips curled awkwardly away from its teeth—has a name. It’s called the flehmen response, and yes, it looks ridiculous. But for many mammals, it’s a critical part of their sex life. »
If you were a midwife or a doctor attending childbirths during the 17th century, you might have owned a tiny anatomically correct doll like this one. Carved from ivory by German, French or Italian craftsmen, these tiny anatomical manikins opened to reveal the normal arrangement of human organs, including the lungs,… »
Most of us would rather not think about what happens to our bodies after death. But that breakdown gives birth to new life in unexpected ways, writes Moheb Costandi.
Most of the time, the male Superb Bird of Paradise is a fairly nondescript black bird. But when it tries to attract a mate, it flips its feathers around to create a fluorescent kabuki mask that you’ll never forget. In this video, ornithologist Ed Scholes explains how the bird creates the illusion.
