Genetic changes that create ever-expanding numbers of identical sperm cells are more widespread than previously thought, according to a new study led by researchers at Harvard Medical School. The team ...

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 ...

Potentially harmful DNA mutations can amass in men's sperm as they age, new research has found, which may in turn impact the number of mutations passed on to children – and the risks of disease in the ...

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 ...

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 ...

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 ...

Polβ-dependent DNA demethylation is essential for neuronal development. During neuronal development, DNA demethylation at enhancer regions is required to activate gene expression. In the absence of ...
