What causes an unpleasant odor on the glans penis?

An unpleasant odor from the glans penis may result from various causes, with common ones including phimosis (tight foreskin), inadequate hygiene, and bacterial infections. Phimosis can lead to accumulation of smegma under the foreskin, causing odor; poor personal hygiene can also promote bacterial growth and contribute to unpleasant smells. Furthermore, if the odor is accompanied by symptoms such as itching, redness, or swelling, it may indicate a bacterial infection, and prompt medical evaluation is recommended to determine the underlying cause and receive appropriate treatment. To prevent odor, it is advisable to maintain good local hygiene by bathing regularly and changing underwear frequently. Individuals with conditions such as phimosis should seek medical advice and consider surgical correction if necessary. Additionally, avoiding unhygienic sexual practices can help reduce the risk of bacterial infections.
