Scientists have used a tiny plastic “obstacle course” to test how much sperm would struggle to navigate during sex in the weightlessness of space. Some particularly resilient sperm still made it through the course, suggesting that conceiving children in space will still be possible, according to research published on March 26 (2026). However, a bigger problem could be that the development of embryos after fertilisation was harmed by a lack of gravity, the Australian team of researchers found. This worked out to be roughly a 30% drop in successful fertilisation, according to the study in the journal Communications Biology. “We are still a long way from seeing the first space baby,” she said.
