We all know, thanks to Marvin Gaye, that "good lovin' ain't easy to come by." But what if it were? What if there existed a real-life love potion?

The idea of a love potion might sound preposterous, a relic of the days of alchemy, sorcery or magic. But now there's some real science being done on the biochemistry of love and attraction that could soon make love potions serious business.

Case in point, a new study out of the University of Bonn in Germany has recently discovered that an oxytocin-like spray has the ability to instantly make men 15 percent more attractive to their female partners, reports the Daily Mail.

Researchers have long been interested in the hormone oxytocin due to its association with feelings of love and affection. Although it is most commonly associated with maternal bonding and hugging (sometimes even referred to as the "hug drug"), oxytocin has also been linked to orgasms, feelings of trust, the alleviation of social inhibition, as well as to the desire for monogamy.

With this in mind, University of Bonn researchers concocted a spray containing syntocinon, which is a synthetic form of oxytocin, and spritzed it into the noses of a group of women in their 20's. Each of the women in the study already claimed to be "passionately in love" with their current partners, but upon receiving the spray their feelings got a boost. The results showed that the women suddenly found their partners to be 15 percent more attractive compared to when they were merely given a placebo.

There was one exception: Women who took contraceptive pills experienced no boost at all by the drug, for unknown reasons. But the results were otherwise conclusive: The syntocinon spray almost instantly enhanced feelings of attraction among women toward their male partners.

Although this study only looked at the effects of the drug on women, there's reason to believe that it works both ways. A previous study performed in 2013, also by University of Bonn researchers, found that men spritzed with synthetic oxytocin experienced a similar boost in attraction to their female partners.

So this could be the workings of a real-life love potion, though our understanding of how oxytocin works is still in its infancy, and more research needs to be performed. Until then, at least there's hope for men and women everywhere who could use a 15 percent boost in attractiveness to their partners. And really, who couldn't?
