My left testis is little bigger than right. I think there is some (soft chewing gum like fatty skin accumulated at bottom .may be change in epididymis)) As I never feel any pain in any testis ((((Except hit by anything)))) (And why the erection is in left side)) As in my childhood I got (5 to 6 ) time hit in testis on bicycle. Is there any thing to worry.. Plz response... And Plz tell if that i missing to write any particular.. Thanks
