The U.S. Centers for Disease Control and Prevention is asking pregnant women to abstain from sex if their partner has recently visited an area where Zika is currently active. The CDC’s updated guidelines also offers advice for men and their nonpregnant partners.
It feels like video games got raunchier in 2015. More games tackled sex in novel ways this year, and many of the biggest controversies of 2015 revolved around nudity.
We have a vaccine against the virus that causes cervical cancer. It’s as safe as any other vaccine, and getting it for your tween son or daughter—or yourself, if you’re in your early twenties—is a no-brainer. Don’t buy into bogus exposés on “dangers” that don’t really exist.
From 2001 to 2013, 1,367 American soldiers suffered some kind of genital injury while deployed in Iraq or Afghanistan. Some time in the next year, one of these men will receive the first penis transplant ever performed in the United States.
What do you do when you work at a zoo, at an outreach program designed to give the public an up-close look at the safer animals in your care, and the animal you’re showing off gets an erection? If you work at the Currumbin Wildlife Sanctuary, you get to work.
A mouse’s sperm is much, much larger than an elephant’s sperm. A fruit fly produces the longest sperm known to science. Why do tiny animals make big swimmers, but large animals make small ones?
Anyone who’s been paying attention knows that high school sex education in the United States is an unholy mess. And as a result, an alarming number of students enter college with little knowledge about how their bodies work in terms of reproductive health.
People are crap at estimating risk. They’re scared of flying, for example, even though it’s far less likely that their metal sky-bird will crash and burn than their car will get crushed by a truck on the way to the airport. Combine that with a tendency to get judgey about sex, and you’ll find attitudes that can have…
Seahorses are famous for flipping the usual reproductive pattern on its head–a seahorse female impregnates the male by laying eggs in his pouch, and the male cares for the developing babies through an 18 day “pregnancy.” But you have to wonder: how does she get her eggs in there?
Male animals can be greedy about paternity. They’ve evolved a ton of different strategies to help them monopolize a female’s eggs. Beating up rivals is a general favorite. Some species use long bouts of sex to keep females away from new mates. Still others stop up female genitals with gooey plugs or bits of broken…
Some people cheat on their partners. Others wouldn’t dream of it–the risk is too huge. A new video from ASAP Science lays out how genetic differences in the neurotransmitters that promote risk-taking and social bonding might influence people’s willingness to stray.
Three researchers at the National Bureau of Economic Research have published a working paper showing how increasing temperatures over the next century could mean fewer babies born–because, to paraphrase Cole Porter, it’ll be too darn hot.
The corals of Australia’s Great Barrier Reef are having their annual orgy. Although some corals brood their eggs in their bodies, or bud off clones, most of the Great Barrier Reef’s corals–140 species worth–release clouds of eggs and sperm into the water en masse.
Farming emus means breeding emus. And Irek Malecki of the University of Western Australia thinks that the results could be improved with a bit of artificial insemination. But it’s easier said than done, as detailed in this amusing video.
Cat sex videos are all the same. The tom mounts the female, she arches her back and moves her tail aside–a response called lordosis, by the way–and the two of them get down to the act. But soon afterwards, the yowling starts, followed by the spitting and swiping. Why so angry, kittycat?
Between our smartphones, Fitbits, and other wearable sensors, we have tons of opportunity to capture how we move during the day. So it’s not surprising that some people opt to capture the data when they have sex. But as far as I know, only one person has made music from it.
Psychologist Peter Jonason of Western Sydney University is running a study examining who fakes orgasms (or other types of sexual pleasure) and why they decide to do it.
Catherine Scott is a graduate student working toward her Ph.D. at the University of Toronto. She’s studying the courtship behavior of black widow spiders. That means that her experiments often involve waiting for spiders to have sex.
