Sniff your way to love? Singles who attend so-called pheromone parties haven't ruled it out.
The get-togethers - which have been held in New York and Los Angeles and are planned for other cities - ask guests to submit a slept-in T-shirt that will be smelled by other participants.
Then, voila! You can pick your partner based on scent, or so the theory goes.
The parties started as an experiment in matchmaking by a Californian woman weary of online dating, but it turns out they also have a root in science.Researchers have shown that humans can use scent to sort out genetic combinations that could lead to weaker offspring.
At an art gallery in Los Angeles on a recent night, partygoers huddled around several tables covered with plastic freezer bags stuffed with shirts and an index card bearing a number.
Once they found one they liked, a photographer snapped a picture of them holding the bag and projected it onto a wall so the shirt's rightful owner could step forward and meet his or her odour's admirer.
Konstantin Bakhurin, a 25-year-old neuroscience graduate student, said he bypassed the bags that smelled like baby powder or laundry detergent or perfume in search of something more unique: the owner of a distinctive yellow-T-shirt whose fragrance he described as "spicy".
"I think it's probably a bit more pseudoscience," said Bakhurin."I just kind of came here for kicks to see what would happen."
Judith Prays, a web developer, said she came up with the idea for pheromone parties after she failed to find a match online.Prays said she would date men for about a month before things soured, until she started seeing a man who wasn't what she was looking for and wound up in a two-year relationship.
What she remembered was his smell."Even when he smelled objectively bad, I thought he smelled really good," the 25-year-old said. "And so I thought, OK, maybe I should be dating based on smell."
At first, it was an experiment. Prays invited 40 friends to a party in New York and asked them to sleep in a T-shirt for three nights, put it in a plastic bag and freeze it, then bring it to the party.
Bags were coded with blue cards for men and pink for women and numbered so the shirts' owners could pinpoint their admirers.
The night was a hit; half a dozen couples hooked up and one pair formed a relationship, Prays said.
Since then she has held similar parties in New York and Los Angeles and is planning others for Atlanta and San Francisco.
In Los Angeles, several dozen 20-somethings posed playfully for the photographer with shirts they liked, hoping the owner might step forward and say hello. Few did.Some admitted they had seen their number flashed on the wall but were too shy to identify themselves.
