Alright all you science aficionados out there. Can you make sperm from a woman’s stem cells?
I am pretty darn certain you can. The chemical signals to produce sperm cells from a stem cell are being supplied by the lab. You would just have no sperm containing the Y chromosome. So an in vitro fertilization would produce all female offspring. Men truly are soon to be superfluous :-)
