According to the research, Androstenone emphasizes masculinity and dominance. When exposed to it, women may perceive men as more attractive, while other men keep their distance [1]. Men who liked Androstenone aroma may have a more favourable opinion of other men. This compound is sprayed on cinema or theatre seats, which are difficult to sell etc. What is more, Androstenone can improve cooperation between men [2]. Female perception of Androstenone depends on the menstrual cycle phase [3] and on contraceptive pills use [3]. It is considered to be a socio-sexual male pheromone [3].
