<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, Im having some issues with my testicles. I dont feel as energetic as I used to, and my mood seems to be lower. What could be causing this?  <response>: Based on your symptoms, its likely that you have a testicular disorder. I would recommend a few medications for treatment, including testosterone, tadalafil Cialis, sildenafil Viagra, vitamin B 12, vardenafil Levitra, cholecalciferol, calcium citrate, darunavir Prezista, peginterferon alfa-2B Sylatron, and ribavirin. Well need to do some further testing to determine which medications will be most effective for you.
