Male penis with white scum-like may be caused by inflammation, such as glansitis, or may be caused by circumcision, penile cancer and other factors. 1. Glans inflammation: Usually, due to infection, trauma or irritation, inflammatory lesions may appear on the glans area of men, resulting in redness, swelling, vesicles, ulcers, as well as white dregs-like secretion on the glans. 2. Hypospadias: if men have hypospadias due to congenital factors, the head of the penis cannot be exposed in the natural state, thus forming a cavity between the glans and the prepuce; urine and other secretions will be accumulated in the cavity, so white soya bean dregs-like discharge will appear. 3. Penile cancer: it is due to unclean sexual intercourse, infection of human papilloma virus, long-term chronic inflammation of glans and other factors, which leads to malignant neoplastic lesions on the head of penis, coronal groove and other parts of the penis, and therefore, white soya bean dregs-like secretion will appear in the urethra. Male penis with white dregs-like material may also be caused by other factors, it is recommended that patients go to the regular hospital in a timely manner, under the guidance of the doctor to clarify the cause of the disease after treatment, and strive for early recovery.
