Masturbation does not cause penile arteriovenous fistula. Frequent excessive masturbation may cause congestion and enlargement of the reproductive organs, causing cystitis, urethritis, glans penis, prostatitis, prostate hyperplasia and other diseases. In addition, it may cause dizziness, fatigue, tinnitus, memory loss, lumbago, hypogonadism and other symptoms, but will not lead to arteriovenous fistula. Arteriovenous fistula is mostly due to congenital developmental factors, that is, the penis cavernous vein closure disorder, is a clinical cause of male erectile dysfunction. Erectile dysfunction caused by penile arteriovenous fistula should be promptly consulted and treated under the guidance of a doctor.
