Humans living in space for months, years, or even generations will need to navigate sex in a zero-gravity world.

Sperm may lose their ability to navigate in microgravity, raising new questions about whether human reproduction is possible ...

It seems paradoxical: embryos formed in microgravity initially show increased vigor, but then encounter growth problems. This ...

Floating in near-weightless conditions can be disorienting for even the most experienced astronauts. Male reproductive cells—sperm—also seem to get confused in simulated microgravity, which has ...

New study finds microgravity disrupts sperm and embryo development, raising concerns about human reproduction in space.

A new study suggests humans face barriers to reproducing in space, with microgravity disrupting sperm movement.

The researchers put samples through a simulation mimicking both the female reproductive system and the zero-gravity ...
