The Empty Oven is one of those historical facts that skeptics just can’t explain.

Quote:As humankind moves toward the goal of establishing a long-term presence on the moon and Mars, the question of whether reproduction is possible in extraterrestrial environments may no longer be merely hypothetical. And new research using ​simulated microgravity conditions has identified some major challenges.

Experiments conducted by scientists in Australia found that microgravity conditions, simulated in a laboratory, disrupt sperm navigation, reduce ‌fertilization rates and, when exposure is prolonged, compromise the quality and survival of early embryos.

They found that human and mouse sperm cells were around 50% less effective at swimming through a channel mimicking the female reproductive tract under these conditions compared to normal gravity. In mouse eggs, this translated into a drop of roughly 30% in fertilization success. The research also revealed complications in early embryo development.

"It is not the ability to swim that is affected. Sperm in microgravity still move, they just cannot find their way. The function ​that appears to be disrupted is navigation, the ability to orient and move with purpose toward a destination. We believe this happens because many of the proteins on the surface of sperm act as ‌mechanosensors, tiny ⁠molecular devices that detect physical forces including gravity," McPherson said.

"When that gravitational pull is removed, these sensors appear to be thrown off, leaving the sperm without a reliable frame of reference for up, down or which direction to move. It is a bit like trying to navigate a maze blindfolded and spinning," McPherson said.
