Men get mold. Mold infection is usually a conditional pathogen. Only with low resistance or long-term use of antibiotics will mold infection occur. For male patients with diabetes or low immune function, the possibility of fungal infection of balanitis foreskin is very high. In this case, the patient's penis foreskin will appear redness, pain, itching, discomfort and other symptoms. White secretion can be seen on the penis head, and mold hyphae can be seen on secretion inspection. Treatment is mostly local cleaning and antifungal drugs, while controlling the basic diseases.
