Northeastern University biologist Jonathan Tilly is certain he’s found egg-making stem cells in adult mice. If he’s right, it would refute decades-old work that showed female mammals finish making all their eggs before or shortly after birth. This might make it possible to grow new eggs inside the ovaries of older…
If more of the educational videos kids watched about a sperm's magical luge ride through the Fallopian tubes looked and sounded like this, you can bet someone would have made a "Journey of the Sperm" video game by now. It could still be a great game, but only if it were an ongoing MMO tournament that restarted every…
It's official: Love Actually is everywhere. Even on the Denny's Tumblr. Yes, Denny's has a Tumblr. That's the provenance of this gif, in which a strip of bacon professes its love for an egg.
If your first period signals the official "start" of your usefulness as a baby vessel, then menopause is the long, slow death wail of your fertility. No matter how much money you throw at your uterus, if your ovaries go menopausal it's all systems no on mission pregnancy. Or, at least, it used to be. Everything might…
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…
A popular Eastertide event in Colorado has been cancelled this year after the event's organizers say it's gotten dangerous for participants. The rough-and-tumble, no-holds-barred, collarbone-snapping competition was a neighborhood egg hunt, and the parties to blame for turning it from a sweet holiday tradition…
The world, and especially our mother, never tires of telling us that our biological clocks are ticking. We'd better have those babies sooner rather than later because we're running out of eggs, they say relentlessly. And there's a pretty good reason: Unlike our male counterparts, who produce sperm until they're old…
Interviews with sperm and egg donors reveal an interesting dichotomy: while men who give sperm think of themselves as fathers, women who donate eggs don't see themselves as moms. This may say a lot about how we view motherhood and fatherhood.

The process of ovulation has been for the first time — if you can believe that — caught on film. Jacques Donnez of the Catholic University of Louvain in Brussels was about to perform a partial hysterectomy on a patient and captured her ovulation on film, a process that took approximately 15 minutes. Scientists used to…
