Scientists have identified a “selfish selection” process in male reproductive cells that drives increased mutation rates with paternal age. This biological mechanism, compared to early tumor growth, may explain rising congenital disorder risks in children of older fathers according to recent genetic research.

Rising Paternal Age Linked to Increased Mutation Transmission

Researchers have identified a concerning biological process in aging males that reportedly drives increased genetic mutations in sperm, according to recent scientific reports. The phenomenon, termed “selfish spermatogonial selection,” appears to amplify mutation rates as men age, potentially explaining why most new mutations in children originate from the male germline.
