Even when not consciously
detected, 5a-Androst-16-en-3-one, can evoke a detectable odor-like response in the brain.

Male subjects who could not perceive the pheromone
5a-androst-16-en-3-one, produced similar orbitofrontal changes on PET compared with perceptible phenylethyl alcohol
(rose).

"In this study we use the pheromone 5a-Androst-16-en-3-one,
which is a
boar taint steroid, a variation (androsta-4,16,-dien-3-
one) of which is found in human axillary sweat."
I
welcome an explanation of the chemical difference (e.g., variation) between 5a-Androst-16-en-3-one and
androsta-4,16,-dien-3-one
"Irrespective as to whether there are specific human
pheromones, or if the human
VNO is responsible for their
detection, we found activation in the odour-relevant regions of
the human
brain..."
"... it is remarkable that the activation of the orbitofrontal
cortex was independent of the
perception of the odor."
