Epididymitis

Definition:

An inflammation of the epididymis (the structure that is the first part of the duct draining each testis).

Causes, incidence, and risk factors:

Epididymitis is typically caused by bacterial organisms associated with urinary tract infections, sexually-transmitted diseases (such as chlamydia and gonorrhea), prostatitis (infection of the prostate) or prostatectomy (removal of the prostate). An increased risk is associated with sexually active men who are not monogamous and do not use condoms. Men who have recently had surgery or have a history of structural problems involving the genito-urinary tract are also at increased risk (regardless of their sexual behaviors).

Epididymitis may begin with a low grade fever and chills and a heavy sensation in the testicle. The testicle becomes increasingly sensitive to pressure or traction. There may be lower abdominal discomfort or pelvic discomfort and urination may cause burning or pain. On occasion there may be a discharge from the urethra, blood in the semen or pain on ejaculation.
