Blue Light May Lead to Arousal
Red may be the color of passion, but blue seems to make it happen. Scientists in Zurich have found a way to trigger reliable erections in males suffering from erectile dysfunction by injecting a gene construct into the erectile tissue of penises. When exposed to blue light, molecules create a process that leads to an erection, without any need for sexual arousal. The injection might help men over 60, who suffer from erectile dysfunction 50 percent of the time.
