How sperm age: a study warns that older men accumulate more mutations in their testicles than previously thought

A recent study led by the Wellcome Sanger Institute and King's College has revealed that older men accumulate more mutations in their testicles than previously thought, demonstrating that the passage of time leaves a more complex mark on the DNA of male reproductive cells.

The findings provide new scientific insight into how sperm age and highlight the genetic implications associated with advanced paternal age.
