Normally you can not check the spermatic veins by yourself. However, it is possible to perform a preliminary self-examination in the case of serious diseases of the spermatic veins. Abnormalities of the spermatic veins are mainly characterized by varicose veins, which are usually difficult to detect by self-checking in mild cases, but can only be detected in severe cases. The affected side of the scrotum may be enlarged, with a feeling of swelling, hidden pain and other manifestations. The scrotum is characterized by tortuous veins, which may appear as earthworm-like masses. Since varicocele is similar to many other diseases, it is recommended that when patients experience symptoms, they should actively seek medical attention to improve the relevant examinations and make a clear diagnosis, and it is not recommended that they make their own judgments about the disease, so as to avoid delaying the condition.
