"Androstadienone, also known as androsta-4,16,-dien-3-one, is a chemical compound that has been described as having strong pheromone-like activities in humans."


"The power of smell is undeniable humans are Influenced by airborne chemicals undetectable as odors, called pheromones. Researchers at the University of Chicago say they have the first proof that humans produce and react to pheromones."


Pheromones, those mysterious, scentless chemicals that some say drive human sexual behavior, have been studied for decades. But now researchers say they've finally found proof that mammals -- such as humans and mice -- are actually programmed to detect and use them."

Ask Men

"Pheromones have been detected in every species from insects to reptiles as sex attractants. Basically, pheromones are subconscious sex signals."
