Seven years after the first gene-edited babies were revealed, biotech startup Manhattan Genomics is reviving the idea of ...

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 ...

The discovery raises significant concerns for human reproductive health. Researchers issue warning about overlooked threat to ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...

We all know the drill for reproduction—sperm meets egg. But mice aren’t people. And the same recipe doesn’t work for human reproductive cells. One reason, according to Dr. Mitinori Saitou at Kyoto ...

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 ...

A team of researchers has found microplastics in all 40 semen samples they examined from healthy men, highlighting the urgent need to study how these tiny particles could affect human reproduction. In ...
