Androsterone has only been identified in humans. Its consideration as a pheromone has occurred because of the fact that men with a higher ratio of Androsterone to Etiocholanone are more masculine.
Homosexual men have lower ratios of Androsterone to Etiocholanone. Thus, Androsterone makes a man appear extra masculine and or dominant, but without the aggressive aura of Androstenone.
This pheromone can give people a feeling of being protected. The wearer should give the aura of reliability normally found in a peaceful or protector alpha male. Androsterone also provides the respect of Androstenone devoid of the potential negative connotations of the aggressive nature of Androstenone. It is better to be a protector than an attacker.
Androsterone has demonstrated the ability to elevate the moods of women.
IT has been suggested that Androsterone may assist other pheromones in their effectiveness.
