AS you have described this it is "an area on one of my testicles that is a bit irregular"
A varicocele is not typically on the testicle, it can be felt as a separate mass, like worms, and does not typically hang from the testicle.
You might bee felling the epidytimus, which is a structure that rides on the testicle.
I will tell you, more importantly, that this needs to be examined. Any mass on the testicle that is new at age 76 is not likely a sudden varicocele.
So, although it might be normal, all causes of a mass or irregularity on the testicle must be ruled out, including tumor.
See your doctor to have this examined.
OK, so that is an initial answer….
