Many women seem attracted to rat-like men anyway... Might work..

WASHINGTON (Reuters) -- A drug that seems to drive female rats mad for sex may offer the first real scientific aphrodisiac for women, U.S. and Canadian researchers have said.
James Pfaus of Concordia University in Montreal, Canada, and colleagues there and at Palatin tested the drug on female rats and found it affected their mating behavior.
The drug, Palatin Technologies Inc's PT-141, is being developed for use to fight impotence in men, but the researchers said tests showed it also aroused female rats.
