No testis

The testis is a male reproductive organ. A normal male has two testes, one on the left and one on the scrotum. Normally, in the later stages of fetal development, the testicles descend into the scrotum. However, common testicular diseases can cause testicular insufficiency, testicular ectopicity, and testicular absentness. Testicular symptoms such as cryptorchidism, congenital testicular disease, and dwarfism can occur.
