Female rats find the scent of sexually active males much more alluring than that of their sex-starved counterparts.
A team of scientists in Ontario, Canada, placed two male rats behind screens

Female rats were then placed in the tank, and overwhelmingly moved toward the successful rat and lingered nearby.
As is common in studies like this, the relevance of this finding to human subjects is unproven.
