What Can Cause an Itchy Penile Urethra?

The tube that carries urine out of your penis (the urethra) can become itchy for several reasons. A common cause is urethritis—inflammation or infection of the urethra. When any bacteria enter the urethra, they can trigger itching, burning, and pain while urinating. Common bacteria causing urethritis include E. coli (which commonly causes urinary tract infections) as well as Chlamydia trachomatis and Neisseria gonorrhoeae (which are sexually transmitted). These sexually transmitted infections are particularly common causes of urethritis in sexually active individuals. Some people may also experience non-infectious urethritis from physical trauma or chemical irritants like soaps or detergents. If the itching persists, it's important to see a doctor who can determine the underlying cause and provide appropriate treatment.
