Scientists in Japan have produced a litter of healthy baby mice from eggs created entirely in a laboratory. The same team reportedly fabricated mouse sperm a year ago, but they say that that was no big. It's the fragile, fickle lady eggs that are the real challenge. And now they've done it! From scratch! Woooooooo!
In some parts of the world, there has been a considerable decline in sperm quality and quantity in recent years, according to reports from sperm banks as well as evidence from scientific research. The cause is not yet known, but some are pointing pollutants and a "modern Western lifestyle," which includes cellphones…
Earlier this week, we learned (again) about the restorative elixir of life that is semen, which can, according to spermspert Gordon Gallup, Jr. and his anonymous survey of 293 college women, cure depression, make women smarter and, possibly, fertilize eggs. This is just what semen does, Gallup's survey seemed to…
Did you hear? That eating nuts will make your nuts grow big and strong? To be clear: I mean eating nut-nuts—not like NUTS. Like walnuts! Not crotch-nuts. I am not saying that you should go out under cover of night and devour human testicles to absorb their powers. Do not do that. Not only is it rude, it will have…
It turns out that it doesn't matter how fast sperm can swim when it comes to fertilizing an egg—it's all about its length. By studying the ejaculate traits of fruit flies (which must be the teeniest load on the face of this earth), scientists found that sperm that are longer and slower are more likely to fertilize an…
The law doesn't require people to get tested for STIs every time they bone someone new, because that would be impossible to mandate and also a little creepy; it's pretty much expected that consensual sex-having adults make their bed so they can lie/sleep with partners in it, etc.
Male contraception may not exist yet — doesn't it seem like it's always just on the horizon? — but eager dudes are already lining up in the thousands to try out alternative forms of birth control geared towards their semen. It's not that we want to make fun of guys like Lenny Smalls, who recently took it upon himself…
We've long been fed the image that sperm make their way to our eggs by wiggling their little tails and magically swimming up our reproductive tract to find the treasure at the end of the line. Well, new research is painting a decidedly less appealing picture of what actually happens when the little sperm get released…
Former Alabama gubernatorial candidate Bill Johnson, a conservative Christian who opposed gay marriage and unsuccessfully ran for governor in the 2010 GOP primary, is leaving his wife Kathy and her three children from a previous marriage for a new life in New Zealand with children he fathered via sperm donation.…
While our manufacturing sector's kind of in the toilet, mining is giving people cancer and causing earthquakes, and our tech industry is running out of ideas for one-button devices to sell to yuppies, at least one sector of the American economy is running full steam — or rather, full balls — ahead: the sperm…
The charming gentledudes-about-town in Reddit's Men's Rights Community have been feverishly running around in their little hamster wheel brains for the last few days in an attempt to help a message board member solve his urgent problem with his girlfriend. You see, it seems this man's dating one of those baby crazed…
Women have been clued into the fact that their diets affect their fertility for a long while now, but a new study has found that what men are eating might matter just as much. The researchers found that the kinds of fat men ate made a difference in the quality of their sperm. For instance, saturated fat found in the…
If you're an average person and not some kind of jizzologist, you may not have given much thought to how sperm actually works. Luckily, scientists have — and now they're telling us that sperm is actually intelligent. Specifically, it seems to be able to count.
Last night Stephen Colbert addressed the possibility that men may soon be able to take their own form of birth control pills. He's concerned that this will destroy the lives of many sacred sperm who could go on to become babies. His solution? Give every man a transurethral ultrasound (ouch!) before they're allowed to…
When couples are having trouble getting pregnant, quite often, the woman heads to her doctor for answers. But, as Time reports, a new product called SpermCheck is now available for at-home tests:
Undaunted by the monumental failure of Personhood USA's push to declare fertilized human eggs exactly the same as grown ass adults in Mississippi, conservatives in Oklahoma have pushed forward with their own Personhood Bill. But one Democratic smartass isn't having it, and she finds the whole thing so absurd that she…
Scientists may have discovered a new form of male birth control, which the media is calling — horrifyingly — the "testicular zap." Of course, guys in India already have access to horrifying-sounding yet effective reversible birth control, in the form of a shot to the scrotum. We asked some dudes which they would…
Two female employees are suing the Bloomington-Normal Public Transportation System for $250 million because their former boss allegedly harassed them — touching them, making gross gestures, and in one woman's case, talking about her husband's sperm.
This morning's GMA took a look inside the growing world of free online sperm donation. Though the FDA is currently cracking down due to lack of regulation, more and more men have shown willingness to give their sperm away at no charge via social networking sites as opposed to selling it to banks. Transactions can be…
You know how a deep voice in a man is a surefire sign of his ability to impregnate you with lots of his genetically-fit babies, which is exactly what you, as a woman, are hardwired to want? Yeah, no. Turns out, dudes with deep voices actually have substandard sperm.
