Sci-fi or, ultra-modern science?
Okay, first of all the human body is... Just something I'm going to have to know about or... Have someone I know, know about before I can continue my research further, I'm no doctor; But it seems to me, we could probably start doing this ourselfs, soon; In the future, maybe.
Think about it... A pill, as digusting as that sounds, 'or, something' - that could get a girl pregnant if she wanted too, administered by some government regulated healthcare-system-thing.
Virgin births and modern day science.
The LAB-Rat rat body is... Again, something I don't know about but... If we could somehow get virgin birth rats, then I think we'd be one step closer to a virgin birth baby.
