Battle of the sexes III - humans

Earlier posts on Battle of the sexes (I and II) were on animals. Now the time has come to start the battle, for earth, between the humans itself.

One side some mad scientists are producing sperms from female stem cells. While on the other, some more maniacs are saying we dont need ladies in future. What's gonna happen is the big question now? Who's gonna win? Who's going to be extinct? I don't care anyway I won't live that long to see the result. But I am so curious to know who will eventually whip the other one out of existence.
