Hard Flaccid Syndrome: A Biopsychosocial Management Approach with Emphasis on Pain Management, Exercise Therapy and Education.

Hard flaccid syndrome (HFS) is a rather rare, acquired clinical entity affecting young men's well-being, sexual and social life. HFS presents with a cluster of symptoms including penile-specific somatosensory disturbances, a semi-rigid penis at the flaccid state without any stimulation or desire, erectile dysfunction, perineal and/or penile pain, associated urinary symptoms, emotional distress as well as other psychosocial and stress-related manifestations. Although its pathophysiology is still not well understood, initial penile trauma causing minor nerve and vascular disturbances to the penis and associated pelvic floor musculature is suggested to trigger the syndrome.
