Ladies and gentlemen, I give you man-made human sperm (made in a laboratory and not by the birds and the bees).
French researchers recently published the results of their work to create human sperm in the journal Biology of Reproduction. The researchers even patented the process. They are not the only players in this field, Chinese researchers made mouse sperm as a stepping stone to eventually create human sperm. If (and when) any of these methods actually lead to a viable human fetus is still unknown.
Sounds very Gattaca.
