Epididymal cysts, if there are no obvious symptoms, may not require special treatment and regular observation is sufficient. If the epididymal cyst is large or accompanied by uncomfortable symptoms, surgery can be considered. Epididymal cysts are also known as seminal cysts. The main site of epididymal cysts is the head of the epididymis, with the body and tail rarely occurring. The occurrence of epididymal cysts may be related to excessive sexual stimulation, chronic infection of the epididymis, and partial obstruction of the vas deferens. The patient usually has no obvious symptoms, but may also have a sensation of scrotal swelling. This lesion develops more slowly, and patients with asymptomatic epididymal cysts usually do not require treatment, and regular observation and review is sufficient. For epididymal cysts that are large, or accompanied by uncomfortable symptoms, seriously affecting the life, etc., surgical treatment can be considered. If epididymal cysts are present, timely consultation is recommended.
