Why there is no symptom when testicular tumor is diagnosed? Testicular tumor usually only manifests as a painless lump in the affected scrotum in the early stage, and most of them are found by chance when bathing. Therefore, we should strengthen the publicity and education so that male friends can pay attention to their own health, learn to conduct regular self-examination of testicles and detect testicular lumps or other lesions early. Fortunately, nearly half of testicular tumors are seminoma, which are more sensitive to surgery, radiotherapy and chemotherapy, and the effect of early treatment is more satisfactory. On the one hand, testicular tumor can affect its sperm development, and the incidence of postoperative fertility abnormalities is higher. At present, it is possible to take fertility examination first and then adopt various methods to preserve one’s fertility such as semen cryopreservation and assisted reproductive technology. For patients who require natural pregnancy, it is recommended to consider it 12 to 18 months after treatment to minimize the risk of fetal malformation. On the other hand, although testicular tumors and treatment may lead to the development of sexual dysfunction, it is mainly a psychological effect of the disease. Patients generally have orgasm and normal penile erection, and only exhibit ejaculatory disorders. Therefore, post-operative patients can have a satisfactory sexual life as long as they relax and adjust psychologically, and under the condition of sexual counseling guidance from professional physicians.
