My 53 yr old husband had an undescended testicle. I wish they had done the surgery for him years ago. I remember they didn't think he would be able to have children; well, we did!
Just in 2001, he was diagnosed with testicular cancer and had surgery to remove one. Well, even at that age it really wasn't a difficult surgery for him! I am only sharing all this 'cuz I want to make sure your son gets checked frequently throughout his years. My husband is fine now.
