Microgravity and higher radiation levels in orbit could disrupt cell alignment, gene expression, or organ formation.

China has become the first nation to send human artificial embryos into orbit, aiming to uncover how space conditions like ...

Male and female reproductive systems allow human reproduction. Fertilisation occurs when a sperm and egg join to form an embryo. An embryo develops into an unborn baby in the uterus during pregnancy.

China's Tianzhou-10 mission just delivered embryo-like structures made from living stem cells to the Tiangong space station.

The experiment should reveal how microgravity affects early human development – a critical question if we ever want to have babies beyond the confines of our planet.
