We tested the hypothesis that isolated steroids, claimed to act like pheromones, affect human psychological state or mood. In the first experiment, we established that two steroids, Delta4, 16-androstadien-3-one and 1,3,5(10)16-estratetraen-3-ol, modulated emotional states within 6 min of exposure. In men and women, neither steroid had specific effects on states of alertness or negative-confused mood. However, both steroids increased positive stimulated mood state in women but decreased it in… 

Sex-steroid derived compounds induce sex-specific effects on autonomic nervous system function in humans.

The authors argue that AND's opposite effects on physiology in men and women further implicate this compound in chemical communication between humans.

The Influence of Menstrual Cycle and Androstadienone on Female Stress Reactions: An fMRI Study

The findings suggest that ANDR enhanced initial evaluation of self-related social threat in ML-females, pointing to a more complex interaction of ovarian/gonadal hormones in social threat processing and stress reactivity.

Sniffing a human sex-steroid derived compound affects mood and autonomic arousal in a dose-dependent manner

Psychological Effects of Musky Compounds: Comparison of Androstadienone with Androstenol and Muscone

Androstadienone's effects on psychological state were unique in comparison with those of androstenol and with muscone, providing additional evidence that androstADienone may be a pheromone.



Mood alteration from treadmill running and its relationship to beta-endorphin, corticotropin, and growth hormone.

It appears that an increase in peripheral beta-endorphin concentration may not be a major contributor to improved mood in response to exercise, but is an indicator of negative mood in males.

Abuse liability of testosterone

In conclusion, single doses of testosterone are devoid of the usual pharmacologic effects that are associated with abuse.

Human exposure to putative pheromones and changes in aspects of social behaviour

Endocrine, cardiovascular, and psychological correlated of olfactory sensitivity changes during the human menstrual cycle.

Signal detection measures olfactory sensitivity (d') and measures of blood pressure, heart rate, body temperature, nasal airflow, and respiration rate, as well as responses to the Moos Menstrual Distress Questionnaire (MDQ), were established throughout the study periods and fluctuations reported in a number of sensory systems during the menstrual cycle are discussed.

Changes in sensitivity to the odor of androstenone during adolescence.

It is inferred that a smaller percentage of females than males becomes anosmic to the odor of androstenone during development, and those able to detect it apparently show a decrease in threshold with age.

Human social attitudes affected by androstenol

Studied the effect of a boar pheromone, androstenol, on social communication among humans. 24 male and female undergraduates were paid to rate photographs of people, animals, and buildings on 15
