But without an ozone or atmosphere to filter out and stop radiation and gamma rays bombarding an astronaut s balls, he d need to wear a lead shield circling his balls to prevent being sterilized from his sperm being radiated in space. Cooked and nuked swimmers can t do their jobs to fertilize eggs in space.

I wonder how zero gravity would affect a developing fetus in the womb also ? Lots of potential problems in that whole process happening out in space too.

I don't think babies experience gravity until they are born.
