Abstract: A condom with a vasodilator delivery system is provided for producing and maintaining the erection of a male penis during intercourse. The vasodilator may be applied as a coating in a suitable pharmaceutical vehicle to the inner surface of the condom during manufacture. Alternatively, the vasodilator may be contained in a transdermal patch adhered during manufacture to the condom inside wall. The transdermal patch comprises a thin, smooth-edged layered structure for dispensing a suitable vasodilator to the penis skin surface. The transdermal patch may remain attached to the condom inner wall during use, and in so doing release its vasodilator into a suitable vehicle and lubricant for spreading to the entire penis skin surface.
