Human body odour, genetic variability, and sexual orientation: A reply to D. Oliva

Neuroendocrinology Letters, 23(4):289-290.

– In a letter to the Editor, D. Oliva has raised
the hypothesis that there might be a guiding thread
through pheromone communication from unicellular
organisms up to humans, which may serve as an expla-
nation for human homosexual orientation. Although we
do not want to reject this hypothesis in its entirety, as
links between olfactory signals and human sexual ori-
entation remain poorly understood, the argument seem
to be too simplistic in light of evolutionary adaptation-
ism and neurobiological research, and requires further
investigation and discussion. Our reply should not be
regarded as criticism, but rather to encourage further
academic discussion.
