"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.

Everything experiences zero g on the ISS. How would you test this there?

You can collect sperm samples in space, too.

Exposure to short duration gravity load changes

Thats what the reduction in "motility and vitality" comes from. There is no way to create those conditions on the ISS so there is no point in considering the ISS for testing this.

The astronauts in the space station didn't teleport there.
