Penile discharge is a condition in which there is a discharge of a substance from the penis that is neither urine nor semen. This discharge usually occurs from the urethra, which passes through the corpus spongiosum of the penis and exits at the tip of the penis. The discharge may be white and thick or clear and watery or contain pus or blood, depending on the underlying cause of the condition. Urethral discharge is usually released in the morning. A discharge from the penis is a common symptom of many sexually transmitted diseases, including gonorrhea and chlamydia, but other problems can also cause it. Most of these problems are not serious, but usually require treatment. Urinary tract infections Usually, urinary tract infections affect women more often, but men also develop them. There are different types of urinary tract infections, depending on where the infection is located. In men, urethritis can cause discharge from the penis. Urethritis is an inflammation of the urethra. Gonococcal urethritis refers to urethritis caused by gonorrhea, which is sexually transmitted. Non-gonococcal urethritis, on the other hand, refers to all other types of urethritis. In addition to discharge, non-gonococcal urethritis can cause: Pain; Burning when urinating; Frequent urges to urinate; Itching; Susceptibility Sexually transmitted diseases (STDs) other than gonorrhea can cause nongonococcal urethritis. But other infections as well as irritation or injury can also cause it. Some potential causes of nongonococcal urethritis other than STDs include: Adenoviruses, these are viruses that cause gastroenteritis, conjunctivitis, and sore throat; Bacterial infection; Irritation from products such as soap, deodorant or detergents; Catheter damage to the urethra; Damage to the urethra from intercourse or masturbation; Genital Injuries Prostatitis The prostate is a walnut-shaped gland that surrounds the urethra. It produces a secretion that is a component of seminal fluid. Prostatitis is an inflammation of the prostate gland. Inflammation can be the result of infection or injury to the prostate. In other cases, there is no clear cause for prostatitis. Possible symptoms of prostatitis include discharge from the penis, as well as other symptoms such as: Pain; Urine with an unpleasant smell; Blood in the urine; Difficulty urinating; Weak or interrupted flow of urine Pain on ejaculation; Difficult ejaculation In some cases, prostatitis resolves on its own or with treatment within a few days or weeks. This type of prostatitis is known as acute prostatitis. But chronic prostatitis lasts for at least three months and often does not go away completely with treatment. However, treatment can help relieve symptoms. Bibliography: National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
