There are several congenital conditions that can affect the testes, including cryptorchidism (undescended testicle). The testes, a pair of male reproductive organs, produce sperm and male sex hormones, including the steroid testosterone. Each egg and sperm produced has slightly different genetic information carried in the chromosomes; this accounts for the differences and similarities between children of the same parents.
