Sperm From Older Men Have More Genetic Mutations

Researchers confirmed that sperm accumulate mutations over the years, increasing the risk of transmitting diseases to offspring.

Human semen not only accumulates genetic mutations with age; as the percentage of sperm carrying potentially serious mutations increases, so does the risk of developing diseases in offspring. This is according to a new study by researchers at the Sanger Institute and King's College London.
