What's So Bad About Danish Sperm?

Danish sperm may be the lowest quality sperm in the world. At least, that's one data point you could pull from a study of how alcohol consumption affects sperm counts. The researchers — Danish, of course — call the results "troubling." » 10/02/14 6:00pm 10/02/14 6:00pm

Are Sperm Really Attracted to the Scent of These Flowers?

A few years ago, researchers made a strange discovery. Sperm seemed to gravitate toward the scent of flowers called lily of the valley. Could this open up a whole new era of scent-based conception and disreputable flower shops? » 9/22/14 11:40am 9/22/14 11:40am

Your Sperm Velocity Has Been Measured and Found Wanting

Human sperm can swim pretty fast, most of the time, but they've got nothing on the sperm of deer mice. What is the deer mouse's secret? Recently, a Harvard professor created a mathematical model of sperm behaviors to figure it out. » 7/24/14 1:12pm 7/24/14 1:12pm

The UK is Importing American Sperm to Deal With Shortage

There is a sperm drought looming over the UK, and they're facing some issues keeping up with the demand.

Scientists Have Created Spermlike Robots Called MagnetoSperm

The weird little tail-whip motion that sperm use to get to their Holy Grail has been co-opted by scientists for use in miniature robots. » 6/03/14 2:20pm 6/03/14 2:20pm

British scientists have finally figured out how sperm is able to connect with an egg. The process is facilitated by a molecule dubbed Juno, a protein that allows sperm to dock to the surface of an egg. The discovery could introduce new fertility treatments and birth control. » 4/17/14 1:30pm 4/17/14 1:30pm

Why 18th Century Biologists Made Copulating Frogs Wear Tiny Pants

The image of a copulating frog dressed in tight-fitting pants sounds quite silly, but it was done in the name of serious research. In fact, more than one biologist dressed up their frogs to solve the mysteries of fertilization. » 3/26/14 1:30pm 3/26/14 1:30pm

These pretty little bubbles are actually bug sperm

Springtails have evolved a rather strange way of mating. The males of these tiny soil-dwelling arthropods never actually get to meet their partners — instead, they deposit drops of sperm on sticks for discriminating females. » 1/21/14 11:30am 1/21/14 11:30am

Scientists have created remote controlled cyborg sperm

Looking to take advantage of sperm's awesome swimming ability, researchers have cyborg-ized bull semen by positioning them inside tiny metal cylinders that can be steered with magnets. This means we now have a way to control a cell's direction inside the body — a breakthrough that could lead to efficient microscopic… » 12/13/13 2:40pm 12/13/13 2:40pm

Sperm Wars Can Create New Species

Take a look at the battle unfolding in this remarkable image. It shows the sperm from two related fruit fly species competing inside a reproductive tract. It’s an evolutionary struggle that, as scientists are now learning, often leads to the introduction of entirely new species. » 10/01/13 8:00am 10/01/13 8:00am

If you can't taste sugary foods, you could be at risk for sterility

Genetics can get really weird sometimes, particularly when two seemingly unrelated traits are connected by a common thread. In a recent and completely unexpected finding, scientists linked male sterility to a genetic inability to taste sweet and savory foods. » 7/03/13 8:30am 7/03/13 8:30am

And Now, Another Educational Fact About Eating Squid Sperm

You've no doubt heard that semen is nutritious, but it seems we're not the only species aware of nature's dirty little secret. Scientists have discovered that female southern bottletail squid readily — and consistently — consume the ejaculates and sperm of their mates. » 6/05/13 12:26pm 6/05/13 12:26pm

Squid sperm will cooperate to inseminate

A number of species engage in swarming behavior, where countless individuals move en masse in some direction. But they're not the only ones. Scientists have now found that the sperm of some squid form swarms, and this peculiar behavior could help the cells to fertilize eggs. » 4/11/13 2:40pm 4/11/13 2:40pm

What's so bad about Spanish sperm?

This is one of those studies that may mean absolutely nothing. Still, we all want to know about the state of Spanish sperm, and at last a group of researchers has done a longitudinal study to provide an answer.
