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 ...

China's Tianzhou-10 mission just delivered embryo-like structures made from living stem cells to the Tiangong space station. Experiments could shed light on how radiation and microgravity affect human ...

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.

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.

For a long time, having children has been a young person’s game. Although ancient records are sparse, researchers estimate that, for most of human history, women most typically conceived their first ...

Scientists have created human eggs containing genes from adult skin cells, a step that someday could help women who are infertile or gay couples have babies with their own genes but would also raise ...

Recently, scientists have reviewed the existing literature to understand how space travel, space radiation, and microgravity affect human reproductive functions. This review was published in Npj ...

Scientists have identified the biochemical signals that control the emergence of the body pattern in the primate embryo. This will guide work to understand birth defects and pregnancy loss in humans.
