Their discoveries show how both resilient and fragile life can be in the absence of gravity. In low gravity, sperm lose their ...

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

Another hurdle has emerged that must be overcome for long-term space habitation and the colonization of Mars. On the 26th (local time), a team led by Professor Nicole McPherson from the University of ...

Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational abilities of sperm are negatively impacted by a lack of gravity.

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

Research findings are available online in the journal Communications Biology. The original story “ Getting pregnant in space ...

Making babies in space may be more complicated than expected, as new research shows sperm struggle to navigate in microgravity. Scientists found that while sperm can still swim normally, they lose ...

Space is big, empty, and apparently very confusing if you’re a sperm cell. According to a new study from the University of ...

For the first time, scientists have used human cells to make structures that mimic the earliest stages of development, which they say will pave the way for more research without running afoul of ...

Human bodies have to be built from a single egg cell that's fertilized by a sperm cell. Many rounds of cell division occur as the body is developing, and it seems that there are plenty of chances for ...
