Pheromones

[PhysiKid25]

I’m doing a project in my Physiology class on pheromones and have found very limited information about it on humans. Can you help me? Thank you.

It does not have much effect on humans, on bees though, it’s a whole different matter.
For some faulty info, just check the spam in your email :D.

Ok… pheromones are chemical substances that one species produces in order to attract individuals of the same species(opposite sex). They are very useful for getting blind dates, when your partner is at a distance from you- the male moth(Bombyx sp.) can feel the pheromones of the female from 11 km away 😯 😯 😯
It also comes in handy it picking your date. The best individuals secrete more pheromones

The reason for this is because they are washed off your body every day when you shower. Culturally, humans have developed a dislike for the “smell” of pheromones.

Actually, the receptors of pheromones don’t function anymore….John Hargrave tested pheromones from online companies and reported no significant results. http://www.zug.com

Thankyou very much for your help. This will definatly help me with my project.

That’s odd, I remember a company marketing pherimones and they’ve done studies about it working.

Um, I have a question here…do we like our own pheromones?? I’ve heard that some people like to ‘sniff’ their own body scent (which contains their own pheromone). If yes, then I can conclude that not all f humans really create a dislike feelings for thye ‘smell’ of pheromones..at least for their own pheromones..:lol:
and another question, in women, do pheromones get more secreted when they’re having ovulations??

Humans actually do have very small nodes right up inside the nasal cavity called VNO, I cannot remember what VNO is short for but I would say the "O" would stand for olfactory

It is a very similar set up to what pigs have, VNO nodes were found by accident in the lab by scientists who were dealing with human skin samples (long story)

VNO stands for Vomeronasal organ (thanks Pubmed)

There you go PhysiKid25, Vomeronasal organ, ask Mr. Google and all will be revealed, pheromones are a very very important means of chemical communications in the animal world especially insects.

Next time you see a procession of ants marching in a line run your finger through the trail and watch the confusion it will then give you a good idea how important pheromones are to ants!

Ha, I’ve done that before. ( The ant thing )

The reason you can’t find anything on human pheromones is because no one has isolated a human pheromone, much less characterize it. There is no evidence that human pheromones exist. The VNO is either absent or not wired in the majority of humans. Repeat: there is no evidence for human pheromones. There are studies that ASSUME human pheromones, but none that find them.

As a side note of opinion, why would I manufacture a chemical, secrete it, allow it to diffuse, and wait for its reception… when I could just say, "Hello, my name is Scott. You are very pretty. I would like to get to know you."

thats right, we ( humans) have no need for primative chemical messages, we haev other advanced ways of communicating,
