Question

Quizplus · Accepted Answer

As men age, their sperm-producing cells undergo more divisions, leading to a higher frequency of random genetic mutations. These mutations can increase the risk of autism spectrum disorder in their offspring. Adrenal hormones, association areas, and the MMR vaccine are not directly related to the formation of genetic mutations in sperm-producing cells.
