PENILE SENSITIVITY IN PATIENTS WITH PRIMARY PREMATURE EJACULATION

Purpose: We investigated penile sensory levels in patients with primar y premature ejaculation to determine whether there is an etiological b asis for this condition. Materials and Methods: Penile biothesiometry was performed in 120 patients with primary premature ejaculation witho ut erectile dysfunction and neurological deficit, and in 66 normal pot ent male volunteers. Vibratory thresholds were recorded at the glans p enis, penile shaft, scrotum and index finger using a biothesiometer. R esults: On the glans penis and penile shaft the values in patients wit h premature ejaculation were significantly less than those in normal p otent men (p <0.001). In normal potent men an age dependency of biothe siometric parameters was noted, with a significant increase in vibrato ry threshold at the glans penis and penile shaft in older patients. Ho wever, in patients with premature ejaculation there were consistently decreased values without age dependency at the glans penis and penile shaft (p >0.05). Conclusions: Patients with primary premature ejaculat ion have penile hypersensitivity, which provides further implications for an organic basis of premature ejaculation.
