Bilateral epididymal head cysts mainly refer to cystic lesions on both sides of the epididymal head. The cysts are mainly due to the local fluid that is not absorbed in time, and over time, local cystic lesions are formed. Some patients may not have any clinical symptoms, and there are no corresponding clinical complications. In contrast, some patients have pain and discomfort at the root of the scrotum due to the increased tension of the local cyst, which may also cause some compression of the parenchyma of the epididymis, forming an obstacle to sperm discharge and forming azoospermia. When cysts appear, physical examination, ultrasound and so on are needed to make a clear diagnosis, and if necessary, surgery can be performed to remove them, and surgical treatment of cysts is a method that can completely cure this disease.
