Human Sperm Produced In the Laboratory
duh P3rf3ss3r writes "The BBC is carrying a report from a team of researchers at Newcastle University who claim to have developed a the first 'artificial' human sperm from stem cells. The research, reported in the journal Stem Cells and Development, involved selecting meristematic germ cells from a human embryonic stem cell culture and inducing meiosis, thus producing a haploid gamete. The authors claim that the resulting sperm are fully formed, mature, human sperm cells but the announcement has been greeted with mixed reaction from colleagues who claim the procedure is ethically questionable and that the gametes produced are of inferior levels of maturation."
I for one, welcome our female overlords. I hope they find me useful and will not use me for food.
Consider a man a wife. The husband is infertile for reasons other than motility. They could now have a child with sperm produced from his stem cells.
Interestingly, this opens the door to biological children from homosexuals couple. Sure it's been foreseen for a long time, still big big can of worm.

Or, 3. if they took stem cells from a lesbian, they could generate some sperm for her, thereby along her to impregnate her other female partner. Next, all they need to do is to generate an egg cell from a homosexual male stem cell. Then, once same-sex couples can successfully reproduce, the religious right is going to go apeshit and all hell is going to break loose! ;-)
