Epididymis surgery can be categorized into incision and decompression and excision according to the surgical methods, and the side effects of the two methods are different. 1. Incision: In case of epididymitis, abscess formation, etc., the epididymis can be incised and decompressed for treatment, and this kind of surgery usually does not cause much harm, so patients don’t need to worry too much. 2. Excision: When the symptoms of inflammation are serious, the epididymis needs to be removed, which may not only affect the fertility, but also cause side effects such as necrosis, azoospermia, spermatitis, prostatitis, and so on. In addition to the above side effects of epididymis surgery, there may also be bleeding, infection and other complications, so patients should be treated according to the doctor’s guidance after surgery to avoid secondary damage.
