Researchers successfully grow working sperm cells in a lab

Bad news, dudes: researchers in Japan have just made fertile mammalian sperm in a petri dish. That's once less reason for women to keep our asses around.

The researchers were able to make mouse sperm cells, and they hope to be able to do the same for humans in the not-too-distant future. They say it could be used to "aid prepubescent boys about to undergo cancer therapies that destroy fertility. It could also protect the reproductive potential of endangered animals that might die before reaching sexual maturity, he adds." Also, it can help women live without men forever and ever, if you take this to it's logical conclusion. We have many other good qualities, ladies! Please, spare us!
