Removal of cryptorchidism results in a decrease in the total number of spermatozoa. Cryptorchidism is a reproductive disorder that includes three conditions: testicular agenesis, testicular ectasia, and testicular descent insufficiency. Although surgical treatment is one of the main treatments to deal with cryptorchidism, patients usually only need to remove the diseased testicle if there is testicular atrophy or malignant changes in the testicle. The testicle has the function of sperm production, such as the removal of unilateral cryptorchidism will lead to a reduction in the total amount of sperm produced in the body; if bilateral cryptorchidism is removed, then it means that he or she will not be able to produce sperm due to the loss of testicles and lose the ability to have children. Cryptorchidectomy will directly affect the number of sperms in the male patient’s body, affecting his fertility. Therefore, choosing the right time to carry out standardized treatment for cryptorchidism as early as possible is an important means to effectively maintain one’s health. If you find cryptorchidism, you should seek medical treatment promptly.
