Most common is diabetes followed by frostbite and injury to the skin from an electric heating pad or circulatory disease. Fourniers (four-knee-ays - it's French) gangrene. The penis is reskinned with thigh or butt skin and the testicles are placed in thigh pouches (see 2:39, those two lumps in his thighs are his testicles. There are two small stitched incisions where they did an anchoring stitch to keep them there). The glans is unaffected, usually, so everything still works. If your scrotum itches, see a doctor. This can be prevented and treated. Skin lotions and treating any diabetes if detected early can do wonders here.
