Cryptorchidism surgery has no effect on sexual function after surgery. The testicles of cryptorchidism patients develop normally during the embryonic period, but only during the process of descending from the retroperitoneum to the scrotum, mechanical obstruction and insufficient hormone secretion cause insufficient power and stay outside the scrotum called cryptorchidism, there is no testicular development disorder and it will not affect sexual function. Cryptorchid surgery only frees and loosens the testicle that stays in the groin or behind the peritoneum to descend into the scrotum, which does not affect the erectile nerve and does not destroy the components of the testicle and does not affect androgen secretion, and cryptorchid surgery does not have any effect on sexual function. After surgery, it is easier to observe the location, size and texture of the testicles, so as to facilitate the detection of future malignant changes or other abnormalities, which can be dealt with early. Both the cryptorchid itself and the cryptorchid surgery will not affect the sexual function.
