Electrically evoked contractions in control group (CG) (a) and study group (SG) (b) male patients. CG and SG experiments in the presence of atropine and guanethidine or atropine, guanethidine, and L-nitro arginine methyl ester (L-NAME). Results are means ± standard error (SE); a, n = 8 patients; b, n = 7 patients. aP < 0.05, bP < 0.01 and cP < 0.001, atropine and guanethidine vs controls; dP < 0.05 and eP < 0.01, atropine and guanethidine vs atropine, guanethidine, and L-NAME
