:blink: The sheer mechanics are mind-boggling!
Seriously though, I can't imagine pregnancy in space would be a good thing. I mean, you're not even supposed to fly in an airplane after a certain number of months.
I belive they have made experiments with labrats (or some kind of rodent) being pregnant in space.
as a result the little rat children had no sense of up or down. if you placed a normal rat upsidedown in an aquarium or something they would turn arouund as they felltowards the bottom and "land" on their feet.
the rats that had been breed in outer space however didn't they just floated downwards wiggeling their little legs without paying any attention to the sensation that is gravity.
Think there was also something about bird eggs not hatching (don't remember if they didn't hatch at all or if they didn't hatch only if introduced to zero grav too early in development)
