Itching of the glans penis accompanied by an odor can be caused by a variety of reasons, including but not limited to fungal infections, bacterial infections, or sexually transmitted diseases. These symptoms usually indicate a local infection or inflammation and require prompt treatment.

Fungal infections are one of the most common causes of itching and odor on the glans penis. In this case, symptoms such as erythema and increased dandruff are usually present. If symptoms worsen in moist or warm environments, this may further suggest the possibility of a fungal infection. Bacterial infections can also cause similar symptoms, especially when accompanied by pain or discharge. Sexually transmitted diseases, such as gonorrhea or non-gonococcal urethritis, can also cause itching and odor on the glans penis, and are usually accompanied by urethral discharge or discomfort during urination.

It's important to note that while the above symptoms may point to some common causes, an accurate diagnosis requires a professional examination by a doctor and necessary laboratory tests. Self-medication may mask the symptoms but will not address the underlying problem and may even worsen the condition. If you experience itching and odor on the glans penis, especially if the symptoms are persistent or accompanied by pain or increased discharge, you should seek professional medical advice promptly.
