Patient: Does cryptorchidism have any effect on fertility and sex life? Is the impact significant? What kind of surgery should be done for adult patients? Is the surgery risky? Doctor: Hello, cryptorchidism is a condition in which the unilateral or bilateral testicles do not descend to the scrotum after birth and stay anywhere in the normal descent process, i.e., they may be located in the abdominal cavity or groin, and the temperature of these places is higher than that of the scrotum, thus affecting the growth and development of the testicles and leading to spermatogenic dysfunction and causing infertility; in addition, cryptorchidism can greatly increase the chance of testicular malignancy, i.e., testicular cancer. Once adult patients are found to have this disease, they should immediately undergo testicular descending and fixing surgery, which is a common surgery with little risk!
