Actually, with mononuclear reproduction (cloning), sperm is technically not necessary.
A woman could have a clone made of herself, and essentially give birth to herself. No men needed (well, maybe lab techs, etc).
If they clone a high-cell organism such as a sheep, they can clone a human being. No one is quite willing to do.
Not yet, at least.
Neither are women in that scenario.
Cloning. Interesting. I think Hampikian should clone himself, and then go (balance of post self-deleted to save the AdminModerator the trouble).
Do they think a woman invented the machinery behind that?
Do they think a woman invented the science behind that?
Do they think that a virus won't just love a batch of identical people?
Wasn't Huxley's Brave New World something akin to that?
I would suggest to you that this may already have happened in secret.
