Odour is sensory stimulation of the olfactory membrane of the nose[1] by a group of molecules.[2] Certain body odours are connected to human sexual attraction.[3][4] Humans can make use of body odour subconsciously to identify whether a potential mate will pass on favourable traits to their offspring. Body odour may provide significant cues about the genetic quality, health[5] and reproductive success of a potential mate.[6][7]
Body odour affects sexual attraction in a number of ways including through human biology, the menstrual cycle and fluctuating asymmetry. The olfactory membrane plays a role in smelling and subconsciously assessing another human's pheromones.[8] It also affects the sexual attraction of insects and mammals. The major histocompatibility complex genes are important for the immune system, and appear to play a role in sexual attraction via body odour. Studies have shown that body odor is strongly connected with attraction in heterosexual females. The women in one study ranked body odor as more important for attraction than "looks". Humans may not simply depend on visual and verbal senses to be attracted to a possible partner/mate.[9]
