I do some research about Vomeronasal Organ (VMO) and wanna share with you. Probably many of you – as a pheromone user- know these allready.
Well, I know Jacobson’s organ on snakes and how they works on these animals from the documentaries. That’s why snakes always waving their tongues into the air. But I didn’t know that Jacobson’s organ also called Vomeronasal Organ (VMO) or vomeronasal pit. Now, I know that humans have Jacobson’s organ just like snakes. Is that be a extrasensory perception on humans? Maybe I can call it sixth sense ![]()
We all know that, traditionally humans have been thought to come equipped with five senses: sight, hearing, taste, touch, and smell. Animals possess several extra senses, including altered vision and hearing, echolocation, electric and/or magnetic field detection, and supplementary chemical detection senses. In addition to taste and smell, most vertebrates use Jacobson’s organ to detect trace quantities of chemicals.
In mammals, Jacobson’s organ is used not simply to identify minute quantities of chemicals, but also for subtle communication between other members of the same species, through the emission and reception of chemical signals (we all know that, they are called pheromones).
However, can we take the effect of pheromones? Or, as a better question, VMO (Jacobson’s Organ) is working on humans?
I read somewhere that, there is no evidence for true vomeronasal sensory nerves connecting the organ to the brain. There are nerves running behind the VNO and extending back to the brain, but they may be only Nervus terminalis, trigeminal and autonomic nerve branches. We may have VMO but, what if there is no connection between VMO and the brain? If it’s like that, all we do in here is just a placebo. (That’s not good to write it
)
As you see VMO was thought to be no longer functional in humans. While humans don’t display the Flehmen reaction, recent studies have demonstrated that Jacobson’s organ functions as in other mammals to detect pheromones and to sample low concentrations of certain non-human chemicals in air. There are indications that Jacobson’s organ may be stimulated in pregnant women, perhaps partially accounting for an improved sense of smell during pregnancy and possibly implicated in morning sickness.
Well, I use pheromones, too. [Ammo and IFM (and also still thinking to order CTTM and Isntant shine)]. Instead all these, I’m a realist man and I’m only interested the RESULTS. There are hundreds of phero-users and many of them are taking positive effects from these products. I think, so do I. So I believe all your experiences (and of course mine
)
Additional research on the Vomeronasal Organ (VNO) I’ve quoted 3 of the 4 citations, just in case the links no longer are active. I’ve also reviewed the topic in a recent article, linked below to my name.
http://www.berkeley.edu/news/media/r…06_sweat.shtml
“Though some humans exhibit a small patch inside their nose resembling the vomeronasal organ in rats that detects pheromones, it appears to be vestigial, with no nerve connection to the brain.”
Back to 2003 for an earlier indication of what researchers know about the human VNO.
Knecht M, Lundstrom JN, Witt M, Huttenbrink KB, Heilmann S, Hummel T.Assessment of olfactory function and androstenone odor thresholds in humans with or without functional occlusion of the vomeronasal duct. Behav Neurosci. 2003 Dec; 117(6): 1135-41.
KEY INDICATION: The human vomeronasal duct, and therefore, the human VNO does not play a major role in sensitivity toward odorants or the perception of a putative human pheromone.

Is the human skin a pheromone-producing organ?
J Cosmet Dermatol 1 Dec 2004 3(4): p. 223.
HighWire Press – Medline Abstract
“It has been suggested that humans might have a special organ within their nose that can transmit such chemosensory information. However, the evidence for this organ is highly questionable. In any case, the main olfactory system is a highly diverse system, capable of transmitting pheromonal information.”
Brennan PA, Zufall F. Pheromonal communication in vertebrates. Nature. 2006 Nov 16;444(7117):308-15.
“More problematic for advocates of the existence of a human VNO are the consistent failure to find vomeronasal nerves projecting to the brain and the failure to find an AOB in adult humans.” (p. 313)

True there is controversy when it comes to the VNO. Like you I am more concerned with results.
In my opinion (not from a study as far as I know) I think that we as humans are much more evolved then animals. We may have a direct pathway to the brain when it comes to scent.
It has been proven that certain normal everyday scents can evoke memories and reactions. Alot of main stream products have begun to use aromatherapy in there products. Johnson and Johnson is just one that comes to mind. If the scent of Lavender can calm a baby and make them sleepy then I dont see why pheromones wouldnt work as well even without a VNO.

I find JVK’s model of pheromonal effect through olfactory pathway to hypothalamus leading to LH secretion and consequently behavioral modification to be the most believable.
But I am a layman and my knowledge is limited. But his posts on this forum and at l-s and particularly his website are a good place to start.
Finally like Tisha and most other users on this forum what matters to me is that they work for me.
Whatever they say, I can use pheromones instead any other colognes or perfumes. They’re not too much expensive as any other remarkable trademarks (Hugo Boss, Lacoste, Kenzo, Fahrenheit…) It’s a good point to not throw away the possibily of if it’s really working. What if, they are really working?
After wearing pheros, I was addicted to them. When i go out without wearing any of them, i feel myself so helpless and unprotected just like lost my guard. It may jus a placebo. However, we also need placebos to trigger our brains abilities ![]()
Your comments attest somewhat to the difference between hard science and soft science that I posted on in the Pheromone Theory section. There’s no reason that both approaches cannot co-exist. But people might want to know more about the different approaches.
As you indicate, my pheromone/hormone/behavior approach is one way of looking at things. The other is more obvious: just see what works. When hard science supports the soft science of what works, the importance of human pheromones might become better known to researchers and the product end-users.

Stimulating the emotional centers of the human brain
Yesterday’s press release from the company that initiated more than a decade’s controversy about the function and presence of a human VNO indicates a significant change in their portrayal of how human pheromones work.
“The Company is also involved in research and product development efforts on new compounds that have been previously identified as stimulating the emotional centers of the human brain.”
Those of you who have followed their research and product development efforts may see the rather blatant change from marketing products that stimulate the human VNO, to “stimulating the emotional centers of the human brain.” Simply put, this runs the gamut from specific effects of putative human pheromones (i.e., their vomeropherins), to very vague effects–most similar to those reported by users of any fragrance product.
I wonder how long it will be until other marketers quit using reports of a human VNO, which appears to be either non-functional or non-existent, in their marketing strategy.
