Cracks in the glans may be caused by prolonged non-erection of the penis, overstimulation, inflammation and infection, acute injury and other factors. 1. Long-term non-erection of the penis: mostly seen in middle-aged and elderly male patients. The penis is in a Microsoft state for a long time, which leads to the wrinkling of the glans skin and the symptom of localized cracks. 2. Excessive stimulation: If you have the habit of frequent masturbation, it is easy to stimulate the glans area, resulting in localized mild damage, causing the phenomenon of cracks on the glans. 3. Inflammatory infection: If men do not pay attention to the hygiene of the glans area, it is easy to lead to bacterial or fungal infection. When the infection is aggravated, it may cause localized cracks, accompanied by tingling, itching and other symptoms. 4. Acute injury: if men’s glans area is over squeezed, external blow, etc., it is easy to lead to acute injury, which may cause local cracks, pain, swelling and other symptoms. In summary, men with cracked glans should immediately go to the urology department of the hospital, clarify the cause of the disease and follow the doctor’s instructions for treatment.
