One of my testicles hangs lower than the other. When ever i tense up this testicle does not move. The other testicle moves up. Dear Kyle, Thank you for your question. You are correct that the testes usually move with exposure to different temperatures in order to regulate their own temperature.
Sperm production occurs best at a temperature slightly below normal body temperature.
I am unaware of any studies addressing this issue and would not be particularly concerned unless you are dealing with infertility or the testicle does not feel normal or is enlarging. I am not aware of any treatment for this either. This information is provided for general medical information purposes only.
