Is conception possible in space, namely on Titan (a moon of Saturn)

Yes. Sperm follow a hormone gradient to the ova in an essentially zero g environment on Earth. Being on Titan wouldn't change that.

Edit: @ Lodar: A fetus develops floating in amniotic fluid. It doesn't experience gravity stress until after it is born. Zero g should have no effect on its bones.

I think very low gravity might be fatal to a fetus, specifically because the bones wouldn't be strong enough to survive the trip through the birth canal.

Why? You can't get any on Earth? And Titan looks appealing?

You must be some kind of a cretin .....

Didn't Kurt Vonnegut write a book about that?
