Rotten eggs might not be welcomed in a woman's kitchen, but they can prove really useful under bed sheets, suggests a new study which found the smell of decaying eggs could make men randy.
According to research that could lead to new impotence treatments, the chemical behind the smell of rotten eggs helps men become aroused.
A gas called hydrogen sulphide - also released when eggs rot and from the exhausts of cars with catalytic converters - is given out by men just before they have sex. Following the study, researchers believe that it could be used to create a rival to Viagra.
"We found that hydrogen sulphide is involved in human penile erection," The Telegraph quoted Professor Giuseppe Cirino of the University of Naples Federico II, as telling The Independent.
"The hydrogen sulphide pathway represents a new therapeutic target for erectile dysfunction and it should be possible in future to deliver drugs that either deliver hydrogen sulphide or that control the hydrogen sulphide production," the expert added.
