費洛蒙迷人愛情香水國內官方網站You can't make someone love you, even on Valentine's Day, no matter what Hallmark, Godiva and FTD may say. But how much do we really know about how love works? What is it that attracts a particular man to a particular woman and (with any luck) vice versa? To see what light science could shed on the subject, I called Professor Martha McClintock at the University of Chicago. McClintock is an expert on odor and behavior who published a famous study in the early 1970s that showed that the menstrual cycles of college women living in dorms became synchronized through exposure to one another's pheromones, those faint chemical signals released from the skin that control the mating rituals of much of the animal kingdom. McClintock has a new study, published in the February issue of Nature Genetics, that makes an even more provocative link between sex and odor--specifically, the odor of a T shirt worn by a man on two consecutive days.

The experiment was simple. The T shirts were carefully prepared (no cologne, no cigarettes, no sex) and then placed in boxes where they could be smelled but not seen. Forty-nine unmarried women were asked to sniff the boxes and choose which box they would prefer "if they had to smell it all the time."

The results would have made Sigmund Freud proud. The women were attracted to the smell of a man who was genetically similar--but not too similar--to their dads. McClintock thinks there's an evolutionary explanation. "Mating with someone too similar might lead to inbreeding," she says. Mating with someone too different "leads to the loss of desirable gene combinations."

McClintock isn't suggesting you can attract a mate by smell alone, but that hasn't discouraged companies like Erox from bottling pheromones and stopping just short of calling them aphrodisiacs. Marketing websites feature links to scientific papers on the power of pheromones. I spoke to Dr. David Berliner, CEO of Pherin Pharmaceuticals, who did some of the initial research. While working at the University of Utah with natural compounds produced by human skin, he noticed a surprising change in the behavior of his male and female colleagues. "They developed an increased level of camaraderie that was hard to explain," he says. There were smiles, eye contact and increased approachability until the skin extracts were removed, at which point the group reverted to normal behavior.

But even Berliner balks at categorizing pheromones as aphrodisiacs. "I've been looking for an aphrodisiac for 11 years, and I'm convinced that there is no such thing," he says. The Food and Drug Administration agrees. It surveyed purported love potions--from oysters to rhino horn--and determined that none of them work. This Valentine's Day, I think I'll stick with flowers, a card and some chocolate.

費洛蒙迷人愛情香水國內官方網站就算是在情人節你也無法使某人愛你,不管印記, Godiva及FTD說什麼,但我們對愛如何發作又了解多少?一個特定的男人是如何吸引一個特定的女人或是反之?為了了解科學方面的發現,我打了電話給芝加哥大學的Marta麥克林托克教授。麥克林托克是氣味及行為的專家,其在1970年代即創辦了知名的研究,發現住在宿舍女性大學生會經由暴露在另一個人由皮膚所釋放出的微弱化學信號控制很多動物配對習慣的費洛蒙下,使得月經週期一致。McClintock一項新的研究,在自然Genetics所出刊,在性欲及氣味間有更深的關連-特別是,一個男性連續穿了兩天的T-恤上的氣味。
