Penile fungal infections can be treated with drugs such as Dakin, fluconazole, ketoconazole, econazole, etc. These drugs are recommended to be applied topically, and oral drugs or intravenous medications are not recommended. These drugs should be used before the foreskin should be turned over, the foreskin and glans should be effectively cleaned and applied on the foreskin and glans once in the morning and once in the evening, and it will return to normal in 3-5 days. Normally, the foreskin should be turned over for good hygiene. If you are married and have a sexual partner, it is recommended that women should be checked for mycosis fungoides, as cross-infection can easily result between husband and wife. Circumcision is also a way to avoid fungal infections if the foreskin is too long.
