Abstract
We studied the voluntary contractile activity of the ischiocavernosus muscl e (ICM) in 21 sexually potent and 97 erectile dysfunction (ED) subjects usi ng a spring balance. A strap was placed around the coronal grove of the gla ns penis and tensioned with the spring balance. Subjects were asked and enc ouraged to contract the ICM against the spring balance. We evaluated the le ngth of stroke, duration of contraction, and maximum contractile force. The length of stroke, duration of contraction, and maximum contractile force s howed statistically significant differences between potent and ED subjects. Diagnosed psychogenic ED and arteriogenic ED showed higher contractile act ivity than cavernous ED and neurogenic ED. Our results corresponded to thos e of previous studies that have ur-ed consideration of the role of the ICM during the process of erection in animal experiments and in human electroph ysiological studies. The spring balance evaluation is a useful, inexpensive method for evaluating the ICM.
