Ever want to make your own sperm? Well, most guys do this anyways... but ladies, any of you ever want to make your own sperm? Well a bunch of scientists are coming close to making human sperm out of bone marrow! So if you have bone marrow (which I hope you do), you can make your very own sperm!It's not quite that simple... and it's not even all that necessary, but yeah... they're getting close to finding a way to do it.
Research led by Professor Karim Nayernia showed that if you extract "mesenchymal" stem cells from the bone marrow, stimulate it with a bit of vitamin A, these cells will actually develop into germ cells. Germ cells are the things that grow up to be sperm. They haven't found a way to make these cells go through meiosis (the process that makes them true blue sperm... well, not blue...) in a laboratory yet. However, one experiment that they did with mice (yeah yeah, poor mice... suck it Heather Mills) involved the same process of stimulating the bone marrow (from the mouse) with vitamin A, but then they implanted the germ cells into the testis of live mice. And voila. They grew into real live working sperm. They haven't tried this out of humans yet... for obviously reasons... very few guys will volunteer to have their nuts chopped open so some hairy old scientists can grow artificial sperm inside.
But either way, it's pretty interesting... and frightening. If this technology gets perfected, it would mean that men would become obsolete. More seriously though, it opens the doors to lesbian couples actually giving birth to a child that is biologically related to both of them by making sperm from the bone marrow of one women and then fertilizing the other woman with it. Neat-o.

Yeah, 'cause we're basically just sperm factories :)
I'd like to point out that a women who only uses a man for his sperm is the type that would also need alimony checks. So no need to worry about dudes going extinct quite yet.
As a (non-lesbian) woman, I would like to point out the most women like men for a lot more than their sperm. Thankfully, you're not going anywhere men.
Nevertheless, a very interesting scientific discovery.
