This Wired article documents an interesting experiment to test the effect of zero gravity on embryo fertilization and development, but the methodology seems flawed to me, primarily because they are testing it on Earth:
>To test these effects, the researchers artificially fertilized mouse eggs with sperm that had been stored inside a three-dimensional clinostat, a machine that mimics weightlessness by rotating objects in such a way that the effects of gravity are spread in every direction.
The same results may hold true in space, but we really need to be doing these experiments in orbit before drawing a conclusion.
