However, the scientists stated that embryo development could still pose a problem.<\/p>\n<p>Studying sperm in space-like conditions<\/p>\n<p>Next week, NASA\u2019s Artemis II mission aims to send humans to the Moon for the first time since 1972. Under NASA chief Jared Isaacman\u2019s new plan, the Artemis program will have a renewed focus on building settlements on the Moon, with a view to eventually colonizing Mars.<\/p>\n<p>All of this poses the question: Will humans be able to reproduce in space? While the new research was focused on microgravity conditions, hypothetical Mars inhabitants will experience roughly 38 percent of Earth\u2019s gravity.<\/p>\n<p>\u201cAs we progress toward becoming a spacefaring or multi-planetary species, understanding how microgravity affects the earliest stages of reproduction is critical,\u201d associate professor John Culton, Director of the Andy Thomas Centre for Space Resources, explained in a <a href=\"https:\/\/adelaideuni.edu.au\/about\/news\/2026\/human-sperm-may-get-lost-in-space\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">press statement<\/a>.<\/p>\n<p>For their study, the researchers tested both human and mouse sperm. To do so, they used a 3D clinostat machine, developed by Dr. Giles Kirby at Firefly Biotech. The machine was designed to resemble the female reproductive tract, and it serves as a \u201cminiature obstacle course\u201d, according to the researchers. The team published their findings in the journal <a href=\"https:\/\/doi.org\/10.1038\/s42003-026-09734-4\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">Communications Biology<\/a>.<\/p>\n<p>\u201cThink of it as a tiny racetrack \u2026 sperm are introduced at one end and have to swim their way through to the other,\u201d the scientists told the South China Morning Post (SCMP) in <a href=\"https:\/\/www.scmp.com\/news\/world\/article\/3348051\/sex-space-sperm-struggles-navigate-without-gravity-scientists-find\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">an interview<\/a>. The machine itself was placed inside a device that uses constant rotation to simulate microgravity.<\/p>\n<p>Space reproduction<\/p>\n<p>The team\u2019s experiments showed that sperm were roughly 50 percent worse at navigating the course under space-like conditions. Interestingly, though, this resulted in roughly a 30 percent drop in fertilization. What\u2019s more, the successful sperm seemed to produce better-quality embryos, which could turn out to be \u201cbeneficial\u201d, according to the scientists.<\/p>\n<p>Effectively, the study showed that reproduction in space would only allow the very fittest sperm to survive, in an interesting application of Darwinian evolution.<\/p>\n<p>The results show that reproduction could pose a real challenge for future space settlers, but it still can\u2019t be ruled out as impossible. However, embryo development is where real problems could arise, and more research is required. <\/p>\n<p>Overall, the study shows that microgravity \u201cmay not be the deal-breaker we feared, but protecting the embryo from weightlessness in those critical first hours will likely be essential for reproduction in space\u201d, Nicole McPherson, a researcher at Adelaide University in Australia, told the SCMP. While we are unlikely to see the first space baby any time soon, a cosmic child may well be in our collective future.<\/p>\n","protected":false},"excerpt":{"rendered":"Scientists have carried out an unusual test to determine whether a child could be conceived in space.
