Researchers often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics because at the molecular level, we have a lot in common with these organisms. Scientists used a ...

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has become impossible to ignore. The standard sperm-meets-egg story posits ...

A sperm donor whose samples helped conceive nearly 200 children across Europe unknowingly carried a cancer-causing genetic mutation — a hidden risk now tied to multiple childhood illnesses and early ...

Scientists have identified a protein that may be key to proper sperm formation. Without it, male mice produced no viable sperm, they found. A team at the RIKEN Center for Biosystems Dynamics Research ...

A team of Columbia researchers has developed one of TIME Magazine’s best inventions of 2025: an innovative AI-imaging advancement that addresses male infertility. The Sperm Tracking and Recovery ...

While whiskey, real estate portfolios and emotional intelligence tend to improve with age, sperm does not. New research suggests that your spunk does indeed sour with time — at least in terms of how ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed ...

An egg cell and a sperm need to hold together tightly in the Fallopian tube in order to fuse, resulting in the creation of a new organism. One key part of this process involves the proteins Juno, on ...

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 ...

The risk of older fathers passing on disease-causing mutations to their children is higher than we thought. Genome sequencing has revealed that among men in their early thirties, around 1 in 50 sperm ...

Harmful genetic changes in sperm become substantially more common as men age because some are actively favored during sperm production, new research has revealed. In a landmark study published today ...

New research shows it's possible to reprogram skin cells into eggs that can be fertilized in the lab, though it's just a proof of concept for now. Reading time 3 minutes A team of scientists has ...
