Human

underarm secretions, when applied to women recipients, alter the length and timing of the menstrual cycle. These

effects are thought to arise from exposure to primer pheromones that are produced in the underarm. Pheromones can

affect endocrine (primer) or behavioral (releaser) responses, provide information (signaler), or perhaps even modify

emotion or mood (modulator). In this study, we extracted underarm secretions from pads worn by men and placed the

extract under the nose of women volunteers while monitoring serum LH and emotion/mood. Pulses of LH are excellent

indicators of the release of GnRH from the brain's hypothalamus. In women, the positive influence of GnRH on LH

affects the length and timing of the menstrual cycle, which, in turn, affects fertility. Here we show that extracts

of male axillary secretions have a direct effect upon LH-pulsing and mood of women. In our subjects, the putative

male pheromone(s) advanced the onset of the next peak of LH after its application, reduced tension, and increased

relaxation. These results demonstrate that male axillary secretions contain one or more constituents that act as

primer and modulator pheromones.
Very interesting article that provides evidence that pheromones cause an

LH spike in females.
