| Pheromones vs Physical Attraction responsible for Hetero/Homo Sexuality?
Posted: 10/16/2009 2:18:18 PM | I found this article rather intriguing and welcome discussion. Is our attraction, as humans, down to pheromones or physical attraction?
Scientists at the University of Toronto found that by genetically tweaking fruit flies so they failed to produce a particular type of pheromone or odour, it turned them irresistible to their species.
Professor Joel Levine, who led the study, removed the cuticular hydrocarbon pheromone, used by the flies to communicate.
They discovered that when the pheromone was removed, it created a "sexual tsunami" where the bugs proved attractive to one another, regardless of sex. The research found that male fruit flies with no history of homosexuality attempted to mate with their pheromone-free males, according to the research published in journal Nature.

Posted: 10/16/2009 3:52:24 PM | | I recently read an article (I'll try to find and post a link) that said there is zero evidence so far of pheremones playing any role at all in human reproduction. Apparently, the pheremone phenomenon, at least as it pertains to human beings, is more media hype than scientific. | |

Posted: 10/16/2009 3:57:30 PM | As usual, I am too lazy to google this, but there was a study within the last 3 months, if my brain is functioning properly ie memory, that disproved pheromones for human attraction. There are only a few seconds after a man or woman emits them before bacteria ie the bo juice gets funky. So if you catch someone fresh out of the shower, it can have the attraction effect for a few seconds before the sweat is exposed. It might be minutes, but it isn't a long period.
There is stronger evidence that we attracted to another because of our hormones and brain wiring. | |

A very interesting point, Aaamm.
However, when we're of childbearing/giving age, and seriously looking for a partner (as opposed to casual physical relationships), I wonder how much of our 'attraction' is down to the 'pull' of the needs of our gene pool and the part pheromones could play therein? | |

It has been proven that one of the reason people are attracted to each other is smell.
Studies have shown that people with dissimilar MHC genes are more attracted to each other.
It is natures way of created the strongest possible offspring by pairing people with dissimilar MHC genes as the child has a greater chance of developing a stronger immune system.

If a female is taking birth control pills, her system is somewhat muted and does not produce as much of a scent.
The Pill may put you off smell of your man and ruin your relationship

There also have been studies tat show pairs that match up with dissimilar MHC genes are less likely to divorce and or cheat.
The ability to detect a male with a very different immune system by his odor is unique to females. This difference between men and women lies in a strip of genes, called Major Histocompatibility Complex (MHC), that control cells making proteins used in recognizing virus, bacteria, pollen and dangerous substances. It appears women, and many female animals, can unconsciously detect the amount and strength of these proteins in males. These proteins detected in males stimulated the females' sexual attraction and drive. Researchers warn that this is not the only criteria females use to select a male for a mate but it appears to be one important decider that has been strengthened in female's evolutionary process.

Posted: 10/16/2009 6:11:25 PM | Pheromones haven't been proven to do any more than perhaps get a woman interested and doesn't do anything to their sex drive. Pheromones have nothing to do with our reproduction. It is when you are in a relationship that the pheromones have more effect because you are drawn to your partner that you are physically close to and can get the pheromones to where they are interpreted in the nose. It isn't some type of laser beam that can spread out near and far. It is coming out of a dude's armpit and if he is holding his SO, she can be drawn closer, more interested. A male can use whatever the thing is in his nose that detects the pheromones to make himself feel more self confident etc. But that is about as far as it gets.
Women wearing cinnamon scent pick up more men than women wearing flowery smells. Nothing to do with reproduction, but hey there is a better chance if you have a SO than if you don't. | |

Posted: 10/16/2009 9:09:27 PM | So, when I give a guy 'the sniff test', it doesn't mean anything?
There is a very interesting book on attraction called, "Why Him, Why Her?" by Helen Fisher. She is a biological anthropologist who is an expert in the science of human attraction. (There is nothing in it about fruit flies.) | |

Posted: 10/16/2009 9:26:12 PM | Helen Fisher is really an interesting person. I don't remember her writing about pheromones, but hormones, personalities, etc. etc. I could be wrong, but I think she is like one the biggest experts right now when it comes to dating, relationships, and breakups, and how the mind etc. react.
DosHermanas did she write something about pheromones? | |

Posted: 10/16/2009 10:14:24 PM | | I actually had to do a research paper and oral presentation on pheremones for a college pscy class. People emit pherimones, thier the human attraction glands that emit a scent for the purpose of attraction and copulation. Women tend to emit more so when shes ovulating. The most intresting aspect of pherimones I covered had to do with mens colognes and womens perfumes. These products contain pheremones from animals. But what I found very enlighting as a man was the intresting fact of why women enjoy wearing it. I thought it was to smell nice for the guys. What I found out was it has an effect on women themselves due to the pheremone in the fragrence, it made them more ready or receptive to guys. And all along I thought she wore it to smell nice for me, how nieve I was. | |
