[|Human|] I am 70 years old, and for the last year one of my testicles has grown to about three times the size of my other testicle. Should I be worried? I am in good health, and had a double hernia operation via my abdomen about four years ago. Your help will be appreciated.
[|AI|]  Good Day, and thank you for being with Chat Doctor ! I am thinking of maybe a HY Chat Doctor.  This is caused by infection or blockage in the lymphatic system. I would suggest getting a scrotal ultrasound to determine for sure the cause of your swelling because a recurrent hernia is not unheard of. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://www.ChatDoctor .com/doctors/
