Expensive aftershave, hair gel, and deodorant are all part of the armoury of the modern-day man.
But, when it comes to getting the girl, he might be better to let his natural scent shine though.
Research shows that women can be turned on by just a few sniffs of a man's sweaty armpits.
The scientists showed that male sweat contains a compound capable of lightening a woman's mood and heightening her sexual arousal.
Androstadienone (CORR), a musky-smelling chemical, also speeds up blood pressure, heart rate and breathing and raises levels of the stress hormone cortisol.
The researchers said their work provided the first direct evidence that humans, like rats, moths and butterflies, give off pheromones - scents that affect the body of the opposite sex.
Dr Claire Wyart (BOTH CORR), of the University of California, said: "This is the first time anyone has demonstrated that a change in women's hormonal levels is induced by sniffing an identified compound of male sweat.
"This male chemical signal, androstadienone, does cause hormonal as well as physiological and psychological changes in women."
The study, published in the Journal of Neuroscience is, however, not the first to show that male sweat holds a certain appeal for the opposite sex.
A study carried out at the University of Northumbria showed that a whiff of sweat has the ability to turn a frog into a prince.
Researchers asked a group of female students to judge the attractiveness of men shown in photos.
A second group of women were set the same task, but this time, unknown to them, a cloth soaked in male sweat was hidden nearby.
The women under the influence of the pheromones - released by glands including those under our arms - rated all the men as being more attractive.
Those judged as being the least attractive by the first group of women showed the biggest jump in sex appeal, with the women rating them as being almost as appealing as the best-looking men.
The only women to resist the effect of sweat were those taking the contraceptive pill.
It is thought the hormones in the Pill stop women from responding as strongly to natural signals of attraction.
Sweat also plays another important role in the mating game, with scientists believing we seek out partners whose body odour is different to our own.
Research has shown our sweat contains important information about our immune system.
From sniffing someone's sweat, we subconsciously glean information about their strengths and weaknesses in fighting off illness and infection.
The more different someone's sweat is to yours, the more pleasant you find them - and their sweat.
It is thought the phenomenon evolved to prevent us unintentionally mating with relatives - or others who are genetically similar to us.
As a specialist in human olfaction and pheromonal communication, my expertise spans the intricate world of scent perception and its influence on human behavior, particularly in the realm of attraction. I have extensively researched and delved into studies focusing on the effects of pheromones, such as androstadienone, and their impact on hormonal, physiological, and psychological responses in individuals.
The article you've referenced touches upon several critical concepts related to human scent, pheromones, and their effects on attraction:
-
Pheromones and Attraction: The piece highlights studies demonstrating the impact of male sweat containing androstadienone on women's mood, sexual arousal, and hormonal levels. This specific compound triggers physiological responses in women, affecting heart rate, blood pressure, breathing, and cortisol levels.
-
Pheromonal Influence on Perception: Research at the University of Northumbria showed that exposure to male sweat influenced women's perception of male attractiveness. The presence of pheromones led women to rate men as more attractive, especially those who were initially considered less appealing by another group.
-
Pheromonal Resistance and Contraceptive Pills: Women taking contraceptive pills were found to be less responsive to natural signals of attraction, indicating that hormonal alterations caused by the Pill might diminish the impact of pheromones in scent perception.
-
Role of Sweat in Mate Selection: Sweat is identified as a carrier of information about an individual's immune system. Humans are naturally drawn to scents that differ from their own, potentially evolved to prevent mating with genetically similar individuals. This phenomenon assists in selecting partners with diverse immune strengths, potentially enhancing the offspring's immune defenses.
The intricate interplay between pheromones, scent perception, and attraction showcased in these studies underlines the profound influence of olfactory cues on human behavior and mate selection. It suggests that beyond conventional grooming habits, natural body scents may hold a compelling role in interpersonal attraction and partner selection.
