Similarly, it is hard to dismiss the effect of mammalian, including human,
pheromones on gonadotropin-releasing hormone (GnRH)-directed neuroendocrine
function, which correlates well with sexual behavior. But a fraction of
the GnRH decapeptide also appears to have direct effects--as a neurotransmitter.
This, in the absence of effect on the gonadotropins and steroidogenesis. This
would allow dual effects of pheromonally induced change in GnRH pulsatility,
e.g., both organizational and activational.
