Both Androstenone and Androstenol are pheromones that are secreted by men and women when they sweat. However, these two pheromones have some key differences. Androstenol is secreted within the first 15 minutes of perspiration, and it is effective only in fresh sweat, before it is overcome by bacteria. On the other hand, Androstenone is formed when sweat becomes older and is exposed to oxygen. The pheromones also differ in their levels of production throughout the lifespan. While Androstenone is produced steadily throughout adulthood, Androstenol is produced at a peak from adolescence to mid-twenties, after which it drops off dramatically.
Androstenol is generally an odorless chemical that becomes dispersed in the air, but some individuals have noted this pheromone as being sweet smelling. This pheromone is attractive, bringing about friendly, non threatening feelings between individuals of the opposite sex. The scent Androstenone cannot be detected by about half of women, and those who can detect the scent may find it unpleasant, neutral, or pleasant. Unlike Androstenol, Androstenone generally triggers negative feelings in women during any time except for ovulation, and it can bring about feelings of aggressiveness or nervousness in both sexes. People have described this pheromone as signaling aggressiveness and dominance. Learn more at Pherolibrary or Love-scent.com.
