The hidden evolution making men’s sperm more dangerous with age

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 dozens of genes under selective pressure, many linked to serious disorders. The work reveals how evolution inside the testes can quietly shape the next generation’s genetic health.
