As you've probably heard by now, in an interview Sunday, Missouri Representative and Republican Senate nominee Todd Akin said he believed that rape-related pregnancy was "really rare." He continued by saying that, "If it's a legitimate rape, the female body has ways to try to shut that whole thing down."
So, now for the facts. Pregnancy resulting from rape is not rare. In fact, a woman is more than twice as likely to get pregnant during a rape than during consensual sex.
Recent research tells us that the sound of our voices betrays clues about our age, whether we’re menstruating (if we’re female), our sexual behavior and our physical strength. All of these factors, evolutionary psychologists say, are indicators of her reproductive potential.
Cornell University researchers used porn and measures of pupil dilation to study arousal in straight-, gay- and bisexual-identifying men and women, reports a study published April 3 in PLoS ONE. The results, which point to surprising differences in arousal based on a person's sex and sexual orientation, corroborate previous research using measures of genital response, opening up a less-invasive method of studying arousal and orientation.
For decades, researchers have argued over the existence of the G-spot, a supersensitive spongy organ on the front vaginal wall that many women report causes vaginal, rather than clitoral, orgasms. Now, a cosmetic surgeon in Florida says he's finally found the G-spot in a dissected cadaver, but rather than settling the question of the G-spot once and for all, the new findings are kicking off a new round of debate.
According to a new study by sex researchers at the Indiana University, women having orgasms during exercise is a real phenomenon. As far as the researchers know, this is the first study that deals directly with exercise-induced orgasms (EIO), known colloquially as "coregasms" because they tend to occur during core-strengthening workouts, like sit-ups and crunches.
At the Oscars this year, Angelina Jolie paired a leggy black dress with bombshell hair. What stood out, though, was her bright red lipstick. I thought she looked great, and--according to science--most of the men watching agreed.
“Are you on your period?” It’s a question most women have been asked at one point or another by their boyfriend or spouse during a disagreement. It turns out that some men actually can tell when it’s a woman’s time of the month—and it’s not because of bratty behavior.
Scientists at California’s Monterey Bay Aquarium Research Institute and the University of Rhode Island recently reported on the same-sex mating habits of Octopoteuthis deletron, a deep-sea squid that indiscriminately shoots sperm packets onto both male and female squids passing by.
There may be few questions of human sexuality more rancorous than those about the female orgasm. Scientists agree that women probably started having orgasms as a by-product of men having them, similar to how men have nipples because women have them. As Elisabeth Lloyd, a philosopher of science and theoretical biologist at Indiana University put it in her 2005 book The Case of the Female Orgasm: Bias in the Science of Evolution: “Females get the erectile and nervous tissue necessary for orgasm in virtue of the strong, ongoing selective pressure on males for the sperm delivery system of male orgasm and ejaculation.” But why we ladies still have orgasms is hotly debated.
On a scale of 1 to George Michael, I’d put my gaydar at about 7. But evidently my so-so ability to spot a gay man sharpens close to when I’m ovulating, or if I’ve recently imagined myself in a romantic situation, according to a series of studies conducted at the University of Toronto. The results show that straight women are better at judging men’s sexual orientation when they are unconsciously motivated to do so, either by hormonal fluctuations or by the power of suggestion.
When time travel finally becomes possible, we might want to think twice about getting it on. According to a new study on tiny shrimp (Artemia franciscana), sex with partners from a different time could kill you.
Back in 2002, psychologists at the State University of New York at Albany published a study in the Archives of Sexual Behavior looking at the potential role of semen in alleviating depression in women. The researchers presented evidence supporting an earlier hypothesis that the hormones in semen have a mood-boosting effect on women.
Critics of the selection that's often involved in assisted reproductive technology – picking a 5’10”, blond-haired, Ivy League grad egg donor, for example – say it turns conceiving a baby into a shopping exercise. It’s probably safe to venture, however, that none of the critics envisioned a day when we’d be bar-coding embryos.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
