_Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell science is moving._

Now we’ve done it. A bunch of Amazon Lesbian Scientists are going to kill off all the men and happily make babies from their own cells. Maybe they’ll let a few of us hang around as pets.

No worries:

That suggests that genes located on the Y chromosome, which female cells do not contain, may be essential for triggering the maturation of the primitive sperm cell.

“coaxed” is such a wrong word to use…
