Penis Disorders

Problems with the penis can cause pain and affect a man's sexual function and fertility. Penis disorders include:

Testicular Disorders

Testicles, or testes, make male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It's easy to injure your testicles because they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.

Code history

Valid since FY2016, when ICD-10-CM took effect on October 1, 2015. No changes since.
