This led to the development of nocturnal penile tumescence and rigidity monitoring (NPTR). Although there is no single test that enables physicians to diagnose the precise etiology and degree of impotence, NPTR provides useful information in a rather noninvasive and inexpensive manner allowing one to direct patients to the appropriate…
