I just read an article on NPR and thought you might be interested too.
Researchers have made immature human sperm cells out of skin cells. Super interesting stuff! If they're proven to be able to produce children, I wonder how much more it would cost than IVF. Doesn't sound to be me to be an inexpensive venture by any means. Especially if you factor in possible litigation with sperm cells made without permission.
I love hearing that researchers are making headway in reproductive medicine, though, even if it's slow. I like that there's still glimmers of hope that someday infertility won't be a big deal.
