Hello, I have gone through your query and I can understand your concern. As per description the size of your epididymal cyst is very small.These cysts are generally harmless and no treatment is required unless the size is large or it cause symptoms. I think your problem is out of unwanted anxiety.It rarely cause sexual symptoms and very unlikely in your case. Treatment is by surgical excision of the cyst,But in your case surgery is not at all required. Medical management by drugs is unsatisfactory. In higher advanced centres a newer treatment called percutaneous aspiration is available .In this method surgeon insert a long needle through your scrotum under USG guidance and aspirate fluid from your cyst. I suggest you to consult a urologist and he will guide you accordingly.You might need few sessions of counselling to avoid unwanted stress . Hope this information helps. Regards. Dr.Shinas Hussain
