Hi my boyfriend has commented that his testicles are cold and this is concerning him as he's never noticed it before.  It's only happened a few times.  We've checked for lumps and haven't found any, but I have noticed his right testicle is slightly larger than the left, but not sure if it has always been like this.
Hello, Some of the parts of our body react faster to external temperature change and the testicle is one among them. Nothing to worry. You can contact me for treatment options. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr K. V. Anand, Psychologist
