Next time you walk into a bar and the hottest chick rips one, she may be sending you a strong signal. A good signal. The stink of rotten eggs could be giving you a nice life indeed. Hydrogen sulphide (H2S) causes erections in rats, and studies are underway to determine if this will be an effective alternative to Viagra.  The penis is packed with spongy tissue that produces an erection when it fills with blood. Nitric oxide (NO) helps relax the walls of arteries that supply the penis, allowing extra blood to flow in. Viagra works by blocking an enzyme that destroys NO.
H2S has recently been shown to relax the walls of major blood vessels too. Now Giuseppe Cirino at the University of Naples Federico II in Italy and his colleagues have found enzymes that produce H2S in human penile tissue.
