"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.

A few seconds of microgravity? Something sounds off, that would probably be enough to be seen in parachutists and fighter pilots. I think I'm going to wait for the peer review on this one...

Also can we stop trying to figure out how humans are going to survive off earth... Until we at least make earth livable again? Like "Genius of the Century" Elon Musk is pouring billions into trying to get man to Mars while actively helping to making earth unlivable.

Like no one should be allowed to leave this rock until it either becomes Paradise or worse than fucking Mars!

Methinks they've given up on earth.
