What Does a Red Urethra Indicate in Males?

When the skin lining the tube that carries urine out of the body (the urethra) appears red, it usually means there is inflammation or irritation. In many cases, this redness is due to an infection called urethritis. Urethritis often happens when bacteria or viruses, such as those that cause sexually transmitted infections, irritate the urethra. For example, studies in clinics that see patients with sexually transmitted infections have shown that men may have redness along with other symptoms such as burning when urinating, discharge, or pain. A red urethra could also be seen with other infections that affect the urinary tract. It is important to note that a red appearance does not give a complete picture by itself—other symptoms, personal history, and sometimes lab tests are needed to understand why it is red. If someone notices a red urethra, it is a good idea to visit a healthcare provider who can investigate further, provide testing, and decide on the best treatment to help clear the infection or reduce the inflammation.
