Penile discharge resulting from the following conditions are considered abnormal. They may include:
Urethritis is the inflammation of the urethra. It is often accompanied with a yellowish-green penile discharge and burning sensation during urination. The frequency and urgency of urination may also increase with urethritis. In less common cases, no symptoms may appear at all.
Balanitis is a more common condition among men, affecting around 3 percent of the male population. It is the inflammation of the glans of the penis and may occur to both circumcised and uncircumcised men. Balanitis may be accompanied by a red, botchy rash that itches. Discharge may occur from under the foreskin. It may also be painful during urination.
Urinary Tract Infection (UTI)
While UTI may be more common in women than in men, bacteria may also sometimes reach the male urinary tract and cause an infection. Symptoms of an UTI include clear or pus-tinged fluid discharged from the penis, urgency to urinate, pain during urination and urine that is cloudy and/or foul smelling. Sometimes a fever may also accompany an UTI.
Sexually Transmitted Disease (STD)
Some sexually transmitted disease may also cause abnormal penile discharge. These include but are not limited to chlamydia, a bacteria caused infection that may show no symptoms at all, or gonorrhea, another common STD that again may show no symptoms. When symptoms are present, they are often pain during urination, swollen testicles and white, yellowish or even greenish discharge from the penis.
