Reproduction for more complex earth organisms is very difficult where there is weightlessness or microgravity. This is because we evolved on earth and all of our bodies have always developed at earth's gravity. Our evolution has made our bodies perfectly suited to grow in our home environment but take away gravity and things grow improperly. We need to have a resistive force constantly applied to us to grow muscles and bones correctly.
Smaller organisms and more simple organisms have been able to reproduce in microgravity, but this is likely because they are so small that gravity never plays a major role in their biological growth.

That hasn't even been tried, so we don't have any idea whether it's possible or not. Let's assume it's possible; I propose that you increase you tax donations by half a penny on the dollar to double NASA's budget and allow them study much more things -- including your personal interest in space sex.

Sez who ? lol. Think about it. It's been done - sort of. In the water ! Same as floating zero g in a space station.

various spiders, insects, etc have had no trouble reproducing in experiments carried into space.
