Men meet obsolescence.

Yep. The Environmental Graffiti blog (among other sources) is pointing out that, biologicially speaking, the testicle is on the way to joining the appendix. Men are no longer necessary to produce sperm:

Scientists at the University of Newcastle have managed to create human sperm cells using a female embryonic stem cell.

The creation means that lesbian couples could soon have children that shared the DNA of both women, rather than having one male biological father. A sperm cell created from one partner could fertilize her partner’s egg.

Sigh. I guess I gotta break it to the guys somehow. Maybe tonight in the shower….
