Human sperm have long been a subject of fascination—not just for their role in fertilization, but for their remarkable ability to navigate through some of the most viscous environments in the body.

An artificial-intelligence tool honoured by one of this year’s Nobel prizes has revealed intimate details of the molecular meet-cute between sperm and eggs. The AlphaFold program, which predicts ...

Researchers showed how what appears to be a tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature ...

A peer-reviewed, multi-clinic study published in the Journal of Assisted Reproduction and Genetics suggests an epigenetic ...

While men may be able to have children much later than women, doing so could come with an increased risk of inherited disease for their children. Researchers from the Wellcome Sanger Institute have ...
