Many neuronal systems and pathways feedback on gonadotropin-releasing
hormone (GnRH) pulsatility. A fraction of GnRH acts as a
neurotransmitter, but GnRH cannot be directly measured in humans. In the
neuroendocrine sequence I have proposed, increased frequency of GnRH
pulses is consistent with elevated luteinizing hormone(LH)/follicle
stimulating hormone(FSH) ratios. If, as I suspect, the goo-gooing is a
classically conditioned response to subliminal olfactory cues, the most
obvious change would be found in assays of LH and FSH. However, to
acheive statisticaly significance might be very difficult, especially
given fluctuations accross the menstrual cycle and and values in women
who take oral contraceptives.
