Abstract

Contemporary plans to establish human habitation on the Earth’s Moon have increased interest in the ability of humans to establish extraterrestrial pregnancies. There is a lack of data to identify if humans could safely reproduce away from the Earth, and even less guidance with regard to whether we should attempt to do so. This work was developed to stimulate investigation into the likely biological and ethical challenges facing the establishment and maintenance of a healthy human extraterrestrial pregnancy. © The Author(s) 2025.
