What happens to male testicles?

Men's testicles appear to droop, which is nothing to worry about if there are no other symptoms. Because testicles change with temperature, they appear to droop when they are too hot. If they are too cold, the testicles shrink to protect them. If the patient has other testicular symptoms, such as pain, itching, or problems with sperm quality, further tests are needed to confirm the diagnosis and aggressive treatment is recommended based on the results.
