Scientists can now produce sperm... from stem cells. That's amazing, truly.
If you can create viable sperm from stem cells that essentially means you can cut out men from the whole reproductive equation. You're a woman and want to have a baby with your girlfriend? Gather some of your girlfriend's stem cells, putty them into sperm, use them to fertilize your egg, and voila, baby-time. Gives a whole new meaning to Best-Friends-Forever (BFF).
