Non-Gonococcal Urethritis (NGU) is a common condition affecting the urethra, the tube that carries urine from the bladder out of the body. Unlike gonococcal urethritis, which is caused by the bacteria Neisseria gonorrhoeae, NGU is typically caused by other microorganisms. This guide provides a detailed yet straightforward overview of NGU, covering its definitions, causes, symptoms, diagnosis, treatments, prevention, and frequently asked questions.
Non-Gonococcal Urethritis (NGU) is an inflammation of the urethra not caused by the bacteria Neisseria gonorrhoeae. It’s one of the most common sexually transmitted infections (STIs) and primarily affects men, but women can also experience it. NGU can cause discomfort, pain during urination, and discharge from the penis or vagina.
Pathophysiology of NGU
Structure
The urethra is a tube that transports urine from the bladder to the outside of the body. In men, it also carries semen. NGU involves inflammation of this tube, often due to infection by bacteria or other microorganisms.
Blood Supply
The urethra receives blood through small arteries branching from the internal pudendal artery. Proper blood flow is essential for healing and maintaining the health of the urethral tissues.
Nerve Supply
Nerve fibers in the urethra are responsible for sensing pain, temperature, and pressure. In NGU, inflammation can lead to increased sensitivity and pain.
Types of NGU

- Mycoplasma Genitalium Urethritis: Caused by Mycoplasma genitalium.
