I have one testicle that is always close to my body. The side of the scrotum that contains this testicle is saggy and seems to contain fluid. There is no pressure on that side of the scotum. The other testicle moves up and down to changes in temperature. The non-moving testicle does not hurt and I did not notice it until my doctor told me. He didn't seem concerned but my wife and I wish to have children and it has been a concern to me. What is your opinion?
