“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.
Who’d have thought a headline could contain all those words
I find it very hard to believe this hasn’t been tested on the ISS.
It’s about the changes in microgravity, extreme G and light. Pure guess, but it’s perhaps testing for travel as much as inhabitant.
Literally (fiction) speaking, I’ve randomly gambled on ~10 generations max before the population crashes if a generation ship arrives and fails to complete an O’Neill cylinder on the other side.
Sound legit? 4am, going to bed, so no read.
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…

Why is creating more humans a good thing in a world with all this suffering?
