View Full Version : VNO: only a small % of us have a functional one so whats with all the madness?
Ok,, so science tells us that in human beings only 8-12% or 10-15% of us do
have a functional VNO. FOr the rest of us its merely a vestigial structure. So is it worth it? WHat i mean is,
are our efforts to mix, match, find ratios, cover scents etc worth our time considering the fact that it would only
affect a certain amout of the human population anyways? Maybe people are mistaking the BO smell with the actual
detection of pheromones. (80% of us can detect this BO apparently) and in my opionion this detection is based on
our olfactory receptors and not from VNO detection. Whether this is true or not, the fact that only a few of us
have a functional VNO (so science inferrs)

Some science infers that. There
have been a few studies done recently that showed excitation of the VNO by mones. The big question is, if it works
and it seems to, is it all that important which organ detects it?
its probably not the case that 80%
have a functional VNO, so I believe that the 'BO' detection is from our olfactory receptors and not from the VNO.
IF this is the case, then pheromones users are in a situation where they substantiall increase their chance of
smelling bad in order to take a small chance (10%) to smell good i guess. LOL

its probably not
the case that 80% have a functional VNO
Based on what? Or is that an opinion without evidence? The debate
is still open as to whether the VNO works or not. Other than that, BO smell is dependent on the amount and type of
mones you use.
Source: well ive been looking
around here and there. A textBook that I used for a course I took in undergrad "Neuroscience" by Dale Purves et al,
they claim its 8% however, these are only extrapolations from tests done on less than 100 people or less than 50
random cadavors so that number ain't so definitive.

Try doing some research on the
web for more recent info. Like I said, there is at least one study that definately demonstrated the VNO was being
activated by none. A good place to start would be the pheromoone reference library and follow phero links from
there.

I read somewhere that the
VNO is only a small part of detecting mones. A test was done with pigs... the male pigs (hogs?) had their VNO
sealed off with surgical cement, but they could still detect a female pig in heat with no change in sensitivity. I
read that on here somewhere, but searched to no avail.

Anyone want to let a newbie in on
what a VNO is? Never heard of it.

Okay a Q.
If only 15% or less
have this, how do you know this?
and how can you tell if you have it personally? Does having a good smell mean
you have this? like being able to smell perfumes easilly etc???

So far no neuronal connection
between the vomeronasal pit and the hypothalamus has been shown. Activation of the hypothalamus has been shown by
two putative human pheromones (vomeropherins) and activation occurs differently in men versus women exposed to
opposite sex vomeropherins. Whether or not the human VNO is vestigial, other putative human pheromones appear (e.g.
androstenol) to elicit the pituitary LH and gonadal estrogen/testosterone (e.g., copulins) response, which has been
demonstrated in other animals regardless of VNO function. Sooner or later most people will realize that the question
of VNO presence and function is not too pertinent, since pheromones do cause hormonal changes. Links to recent
research can be found on the Scientific Evidence page of my web site.

What I find interesting is that
the VNO apparently is damaged and non functioning after a person has had a nose job ( nose surgery). However in my
experience, and I have dated many girls who have had total nose reshaping and reconstruction, and yet the pheromones
have worked just perfectly. In fact what I found is that girls who have had nose jobs are more suseptiple to the
mones then the girls that have not had a nose job. Perhaps its because thier sense of smell is hightend after thier
nose has been cleared of years of pollen (you wouldnt believe what accumulates up our nose after years)
I
dont think the VNO has much to do with pheromone detection, and I beleive its as others suggest, its a hormonal
change brought on by the pheromone molecules entering the nose membrane, the mouth and even the skin.
Example, it only takes the tiniest amount of scent added to natural gas for it to smell bad, thus creating a
certain behaviour that causes alarm bells ringing. For example other hazadous airbone substances, you dont need a
vno for them to cause a certain behaviour in your body.
think of nerve gas, that only needs exposed skin to
be deadly, etc

i don't care how the vno works,
most girls respond very well to the mones and the rest are kinda shy try to ignore me.

surgery).
A research journal article in the 90's advised surgeons to be wary of damage to the VNO.
This effectively "put on notice" that litigation for such damage would result. I've been consulted for cases
regarding loss of the sense of smell, but have yet to be contacted by anyone involved in a case of VNO damage. Since
attorneys don't seem to miss much, I expected to hear about many cases against surgeons.

Don't worry about it, as
JVK said, there is nothing to disprove the theory that a pheromonal pathway exists within normal olfaction.
