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

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

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

Sperm may lose their ability to navigate in microgravity, raising new questions about whether human reproduction is possible in space.

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 ...

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

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, ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...
