Abstract

To compare endogenous catecholamine concentrations in the arousal state with the degree of rigidity of nocturnal penile erections (NPE) in psychogenic impotence, we measured diurnal epinephrine(E) and norepinephrine(NE) concentrations in the systemic and cavernosal blood and compared them with the regidity of the penis measured using the RigiScan in 48 psychogenically impotence patients. The results (pg/ml) were as follows: [Systemic Cavernosal ] [Rigidity (%) ] [E] [NE] [E] [NE] [< 40 (N=8) 55.75+/-40.58 356.50+/-176.64 68.63+/-50.04 833.00+/-449.96] [40-70 (N=14) 112.50+/-95.37 487.86+/-179.62 132.43+/-123.23 900.57+/-487.20 ] [> 70 (N=26) 111.23+/-141.24 558.73+/-386.21 182.04+/-245.37 1,070.85+/-485.97] There appears to be no relation between the catecholamine concentrations in the blood in the arousal state and the rigidity of NPE in psychogenic impotence.
