A new study found that microgravity simulated on Earth hindered sperm cell movement, egg fertilization and embryo development ...

Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational ...

A new study suggests humans face barriers to reproducing in space, with microgravity disrupting sperm movement.

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

A new experiment showed that humans may be able to reproduce in space, paving the way for self-sustaining colonies.

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth ...

The onset of embryo-specific gene transcription, also known as embryonic genome activation (EGA), is a crucial step in the developmental journey of an organism. Although EGA has been studied to some ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...
