“We concluded it is possible that exposure to these chemicals can lower sperm quality, disrupt hormones, and damage ...

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has ...

Longitudinal analyses reveal that most men who bank sperm for oncologic indications ultimately continue long-term storage rather than use their samples for pregnancy. Clear guidance at the time of ...

Because only part of the man's sperm carried the mutation, only the second round of genetic testing revealed the problem. By then, it was already too late. Reading time 3 minutes A man who donated ...

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 ...

In a proof of concept that may reshape the treatment landscape for insulin-dependent diabetes, scientists have demonstrated that human stomach cells can be reprogrammed to secrete insulin—potentially ...

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 ...

HINXTON, England — At first glance, the news sounds reassuring: sperm cells accumulate genetic mutations eight times slower than blood cells, making them among the most protected cells in the male ...

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 ...
