A man's sperm doesn't become completely infertile at a specific age, but fertility declines gradually, typically starting around age 35-40, with more significant changes in sperm quality (motility, concentration, DNA integrity) occurring after 40, making conception harder and increasing risks for pregnancy and child health. While most men produce sperm for life, the decline is gradual, unlike female fertility's sharper drop.
