Without directly saying so, this article attests to the fact that in sheep, and probably in other mammals, it is the effect of testosterone on a specific group of nerve cells in the hypothalamus that not only sets us up before birth to respond to pheromones, but also modulates the response to pheromones throughout postnatal life. You may need to look at the “related articles” to get the big picture. I’m just letting others know that more information is available than what is typically considered.
