Isolation of substances from human vaginal secretions previously shown to be sex attractant pheromones in higher primates.

Fractionation of vaginal secretions from sexually human females by partitioning and chromatographic procedures demonstrates the presence of short-chain fatty acids seen as crucial pheromonal components in previous higher primate studies. In addition, the appearance of these short-chain fatty acids suggests a possible correlation of the rise and fall of hormone levels during the female menstrual cycle.
