정상 한국 남성의 연령별 야간 음경 발기 양상
이성원; 김광세
Abstract
Nocturnal penile tumescence (NPT) evaluation is the single most important step and widely-used technique for the differential diagnosis between psychogenic and organic impotence. It is based on findings that male subjects have erection in association with rapid eye movement sleep. A normal pattern of NPT indicates that neural supply; vascular supply and penile structures are intact. Nocturnal penile tumescence monitoring (NPTM) in the abscence of rigidity evaluation in the assessment of the impotent male is of questionable value; but a study of NPT in 41 healthy male subjects aged 20 to 69 was done by means of portable tumistore NPT monitor to provide normo-tive data for clinical utility in determining diagnosis and prognosis of impotence. The results indicate that NPT occurs consistently in a healthy male population and its expression significantly affected by age; gradual reduction of nocturnal tumescence by increasing age.
