The chromosomes of sperm and egg carry the genetic genes of the father and mother respectively, which record the genetic information passed from parents to their children. Similarly, when sex chromosomes are abnormal, genetic diseases can occur. Chromosomal abnormalities can cause oligospermia and azoospermia, accounting for 2% to 21% of male infertility.
