What Do You Want to Know About Sexual Anatomy?

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.

At Last, We Understand What Turns Fruit Flies On

We’ve been breeding the fly Drosophila melanogaster in the lab for decades. We’ve tinkered with their genes — giving them extra legs, curly wings, or odd colored eyes – in pursuit of understanding genetic inheritance and how tissues develop.

Three Things You Probably Didn't Know About Crab Lice

Crab lice (Pthirus pubis) aren’t crabs at all—they’re parasitic insects that feed exclusively on human blood, and their bites can cause intense itching in their hosts.

Nearly 100 years ago, there was no drug to help with erectile dysfunction, but Bernard Scheinkman came up with an alternative. It’s not clear whether this nightmarish penile splint was ever manufactured — but you have to love the baroque logic of combining a cock ring, an open condom, and a shelf. » 5/14/15 5:50pm 5/14/15 5:50pm

In A Snake Orgy, Ejaculate Can Get Expensive

Every spring, male red-sided garter snakes enter the mother of all meat-markets. While mature males can breed every year, females are only fertile once every three years, which puts them in very short supply. The result? Snake orgy, obviously.
