Studies have been conducted on both men and women. Men where asked to smell shirts of women that were close to ovulation. When they smelt these shirts they had increased testosterone levels, then when they smelt the placebos. Another study showed that when women smelt the smell of men's sweat they felt less tense and more relaxed than when they smelt the placebo. These studies are linking pheromones to sexual attraction and regulating mood.
