Large testicle — is it dangerous?

Dear Alice,

I visited a doctor, and he told me I had a very large tesicle, what is producing this? Is it dangerous?

Dear Reader,

Similar to breasts, hands, and feet, testicles can be asymmetrical or even of different sizes in the same person. It's common for men to have one testicle that is slightly or noticeably larger, often the left one, or that hangs a bit lower, than the other. Usually, there is nothing to worry about. 

On the other hand, sometimes if a testicle has changed in size or becomes swollen, tender, and/or enlarged, that could be serious and needs to be checked with a health care provider. Pain or swelling in the scrotum and testicles can also signify a more serious condition, such as testicular cancer.

Your health care provider can identify if what you have is serious or dangerous. You can still ask your health care provider about this, either by telephone or at another appointment. If you are still worried, which you seem to be, it is fine and acceptable to find another health care provider, perhaps a specialist such as a urologist, to examine you and determine what is going on with your body. The provider can either reassure you that there is nothing to worry about, or can suggest a medical course of action. It is common and smart to get a second opinion, especially if it will put your mind at ease.
