Androstadienone[pronunciation?], 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. It is a metabolite of the sex hormone testosterone: however, androstadienone does not exhibit any known androgenic or anabolic effects. Though it has been reported to significantly affect the mood of heterosexual women and homosexual men, it does not alter behavior overtly, although it may have more subtle effects on attention. Androstadienone is commonly sold in male fragrances, it is purported, to increase sexual attraction.
