the conditon, From what I have read, Only concerns the Veins not the testes. It is an enlargement of the veins leading to and away from the testes.
If the Dr. says it's no big deal then I can only speak from experience with PH's. I have never really had any shrinkage of the boys. They shut down but they didn't really lose size. As far as coming back that happened pretty quickly during post cycle therapy.
