Sexual orientation in all its aspects
Boosted by his research and extensive reading on the influence of biology on sexual orientation, Jacques Balthazart summarises existing knowledge on the subject in a scientific article (1) in which he describes what is known based on animal models as well as on what is currently understood about the influence of hormones, genetics and epigenetics on sexual orientation in humans.

In the context of a special volume of Philosophical Transactions of the Royal Society B (1) on the multiple origins of sexual differences in the brain, the coordinator of the volume asked Jacques Balthazart to carry out a review of the literature on the biological factors that influence sexual orientation. “In this article, I explain what we know about animals and that could have an impact on humans as well as what is actually known about humans”, says the scientist.
