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

Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting atlas links gene expression, cell movement, and tissue formation, offering ...

Findings show ultraprocessed food consumption before conception influences fertility and embryonic development, urging ...

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

Having a baby in space may be far more complicated than expected, as new research shows sperm struggle to find their way in microgravity.

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

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 ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Researchers have discovered that the earliest days of embryo development have a measurable impact on a person's future health and aging. Researchers from the University of Adelaide have discovered ...
