"Exposure to short duration gravity load changes including microgravity, as sustained in a parabolic flight statistically significantly decreases the sperm motility and vitality of human fresh sperm samples," the team found, adding that this may have huge importance for any prolonged human settlement missions in space. 

"In the future, should humans remain in space for long periods of time with exposure to different microgravity and hypergravity peaks, which could range from months to a number of years, reproduction may pose a problem to be tackled."

The mechanism by which sperm motility was decreased remains unknown, with further study needed.

I really hope not. Looking at how humanity has managed this world, I think it’s for the best if the laws of physics and biology are such that we’re never able to escape our solar system.

Large developed organisms don't travel the stars. The building blocks of life travel. I think anyway. Maybe that's too oversimplified.
