Biological and Social Aspects of Human Sexual Orientation: Chemocommunicative Hypothesis

Failure to understand the role of biological and social factors in the formation of some socially important traits in humans could result in unjustified tension in interpersonal relationships. It is caused by a distorted perception of frequently unreliable information, its ambiguity due to the uncertainty of the terminology used and, as a consequence, the impossibility of its correct analysis. Using the term sexual orientation demonstrated the way how genetic understanding of the trait’s formation and data on the control mechanisms of sex formation may clarify and complement our knowledge on the subject. The hypothesis of the chemocommunicative model in the formation of sexual orientation in humans is discussed.
