Due to the misleading concept of the world, over the years, patients who found cryptorchidism dare not go to the hospital for medical treatment, and they are afraid of being ridiculed by outsiders and affecting their marriage, so most of them lose the best time for cryptorchidism treatment, resulting in the decrease of fertility or loss of fertility, or even testicular malignancy, leading to physical and mental pain and family breakup. Cryptorchidism refers to the failure of the testicles to descend from the lumbar region behind the peritoneum to the scrotum according to the normal development process. The testicles that do not descend into the scrotum include undescended testicles and incomplete or ectopic testicular descent, which some people call scrotal emptiness. The testes that do not descend into the scrotum often have different degrees of underdevelopment, are significantly smaller in size and have a flabby texture, and in some cases, the testes are absent and only the vascular stumps of the spermatic cord are visible. The incidence of cryptorchidism with epididymis and vas deformity is 36% to 79%. The pathological histology of cryptorchidism is mainly characterized by the developmental disorders of germ cells. In cryptorchidism, the production of testosterone is basically normal, and therefore, the sexual characteristics are normal. However, the pathological histological changes of cryptorchidism appear before 2 years of age, and the severity of the pathological damage is related to age and testicular position; the older and higher the position, the more obvious the pathological changes. For the treatment of cryptorchidism, it should be treated as early as possible once it is diagnosed. Attention should be paid to the detection of cryptorchidism in newborns. The chances of cryptorchidism declining on its own beyond 6 months are rare, and treatment should be started. Hormone therapy: If the cryptorchidism is still present at 10 months after birth, hormone therapy should be started. However, the evaluation criteria of hormone therapy vary, and whether the effects of retracted testes and other effects are completely excluded, so the efficacy varies greatly among reports. Surgery: The timing of surgery is generally considered best after 1 year of age and before 2 years of age. If the age is too young, the surgery will be poorly tolerated, and some cases can drop on their own or hormonal treatment is effective; if the age is too old, testicular damage and psychological effects will be aggravated. Studies have shown that there is a significant difference between the pathological changes of cryptorchidism before 2 years old and after 2 years old, and the possibility of testicular malignancy increases with age. May patients with cryptorchidism and their family members get out of the misconceptions of the world, seize the best time for cryptorchidism treatment, and reduce the chance of infertility. Return the patient to a healthy body and a perfect life.
