Completely detached, we imagine sex in the weightlessness of space. However, the question of where is actually up and where down could pose challenges not only to astronauts, but also to their sperm – and thus make child-bearing far away from Earth more difficult than previously assumed.
Under microgravity conditions, sperm cells decrease their ability to navigate and fertilize, as well as generate defective embryos. Read more
New Study Shows Why Having Babies in Space May Not Work as Scientists Expected
Living in space sounds exciting, but having babies and starting a family there might be a completely different story. New research shows that microgravity makes it harder for sperm to reach an egg and can weaken early embryo development. The study, published in Communications Biology, adds to growing evidence that human reproduction depends heavily on gravity. Without it, key biological processes begin to break down in subtle but important ways.…
