Penile discharge is often a symptom of STDs, but other conditions can also cause it. Regardless of the cause, it is advisable to seek medical attention to diagnose the cause of the discharge and begin treatment of the underlying condition that caused the complaints, especially if it is a bacterial infection. Until the cause of the discharge from the penis is understood, it is best to avoid all sexual activity to prevent the transmission of a potential infection. When there has been unprotected previous sexual contact, it is important to rule out a sexually transmitted disease as a potential cause of discharge. This can be done through blood and urine tests. Gonorrhea and chlamydia are two of the most common causes of penile discharge. They require treatment with prescription antibiotics. Some sexually transmitted infections do not immediately cause symptoms. This means that it is possible that the cause of the condition is a sexually transmitted disease, even if a person has not had sexual contact for months. If left untreated, STDs can cause long-term complications, so it’s important to get them treated, which also reduces the risk of passing the infection on to other people. Smegma is an accumulation of thick white substance under the foreskin of an uncircumcised penis, consisting of dead skin cells, secretions from the sebaceous glands of the glans penis and fluids. Smegma is not actually discharge from the penis, but it looks similar. All fluids and components of smegma occur naturally in the body. They help keep the area hydrated and lubricated, but with irregular washing, secretions can begin to build up and cause discomfort. Smegma also helps create a moist and warm environment, which can increase the risk of fungal or bacterial infection. Balanitis is an inflammation of the foreskin that usually occurs in uncircumcised men. Although the condition can be painful, it is usually not serious. In addition to discharge from the penis, balanitis can also cause: Redness around the glans and under the foreskin; Tightening of the foreskin; Bad smell; Discomfort or itching; Pain in the genital area Causes of balanitis may include: Skin conditions, such as eczema; Fungal infections; Bacterial infections; Irritation from soaps and other products Bibliography: National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
