Clinical Classification

Clinical Information

  • Orchitis

    inflammation of a testis. it has many features of epididymitis, such as swollen scrotum; pain; pyuria; and fever. it is usually related to infections in the urinary tract, which likely spread to the epididymis and then the testis through either the vas deferens or the lymphatics of the spermatic cord.
  • Non-Specific Granulomatous Orchitis

    granulomatous inflammation of the testis. it is characterized by the formation of granulomas around the seminiferous tubules. history of trauma may be present. it is assumed to be a reactive process due to autoimmune phenomena.
  • Orchitis

    inflammation of one or both testes due to viral or bacterial infections. signs and symptoms include enlargement or tenderness of the affected testis, inguinal lymphadenopathy, blood in the semen, and pain during urination, intercourse, or ejaculation.

Patient Education


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.

You should examine your testicles monthly and seek medical attention for lumps, redness, pain or other changes. Testicles can get inflamed or infected. They can also develop cancer. Testicular cancer is rare and highly treatable. It usually happens between the ages of 15 and 40.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
