Experts Call for Global Framework on Reproduction in Space

A panel of experts warns that long-duration spaceflight poses significant risks to fertility and embryonic development, and current data are too scarce to guide safety. They urge creating an international framework to study reproductive health in space, develop protective measures and fertility-preservation methods, and establish clear ethical guidelines, while making clear that actual in-space human reproduction is not planned and research will rely on simulations and non-human models.
