The doc at my initial class1 did give the old "cojones" a cursory inspection but I think that is for cancer.I would be very surprised and outraged if your doc denied you a class1 on these grounds alone.It is fair to say that they are not looking for the epitomy of human perfection,just someone who can operate an aircraft without endangering paying passengers.If I were you,I'd give them a call,after all the doc WILL spot your problem at the class one even if you don't tell him.The CAA medical department is one of the most helpful government departments I have ever come across,just be honest and I am pretty confident that you will get through.
Best of luck EL Cid
