Odors play an important role in communicating conspecific receptivity, reproductive maturation and dominance status. The major volatile constituents in human vaginal secretions were identified. Data collected during the course of 29 cycles from 9 subjects showed that the nature and abundance of the vaginal organic constituents differed with respect to subject. Only 3 of 9 subjects investigated consistently had C3-C5 aliphatic acids; acetic acid was present in all subjects. Lactic acid was the major acidic compound consistently found in the vaginal secretion of all subjects near the time of ovulation. Cyclical changes in the acidic constituents were demonstrated.
