What is the normal size of a testicle in man 60 years?

The normal size of a testicle in a 60-year-old man can vary, but it is generally considered to be between 15 and 25 cubic centimetres (cc) in volume. However, it is important to note that the size of the testicles can vary considerably between individuals, and there is no single "normal" size. As such, it is always best to consult with a medical professional if you have any concerns about the size or appearance of your testicles.
