Androstenol is a sex pheromone in pigs, possessing a musk-like odor.

It is found in large quantities in boar saliva, but also in smaller quantities in human sweat glands. It is analogous to sex hormones yet has minimal or no androgenic activity. Androstenol is secreted by the adrenal gland into systemic circulation in humans: Systemic effects have not been well studied.

Androstenol, or a chemical derivative, is found in truffles, and is offered as an explanation for how pigs locate them deep in the ground.

Both isomers have a weak, characteristic odor; however alpha-androstenol is often associated with a sandalwood-like aroma due to residual solvents (alkyl acetates).
