There remains the possibility that
(1) a "gay" gene could influence
(2) development of interstitial nuclei of the anterior hypothalamus
(3) these nuclei would contribute either directly or via feedback
(4) hypothalamic gonadotropin-releasing hormone pulsatility
(5) directs gonadotropin pulsatility and thus steroidogenesis
(6) steroidogenic effects on olfactory/vomeronasal receptors could
effect a gonadotropin releasing hormone-directed neuroendocrine
response associated with chemosensory input and sexual orientation.
If so, a genetic predisposition would be influenced by social-environmental
stimuli (pheromones) throughout the concurrent maturation of the
neuroendocrine, reproductive, and central nervous systems, thus linking
the nature (e.g., genes) and nurture (e.g., social environment) that lead
to the development of sexual orientation.
