If males at the prime of their sexual peak tend to have higher fertility and thus produce the most offspring, then evolution should favor females who are able to detect such changes in virility and select them as mates. Alternately, the theory of sexual selection suggests that females may choose mates based on their ability to provide adequate resources to allow the successful rearing of their young.  In humans, control of resources generally increases with age, suggesting that evolution may have favored females who choose older, more established mates. This study was performed to determine whether or not women show any age selection based on the male pheromones present in t-shirts worn by men of different ages.  Female participants sniffed t-shirts that had been worn by male participants in various age categories. When data from all females was pooled, there was no difference in perception of any category of male odor based on the age of the scent donor, suggesting that there is no one, universal age category of males preferred by females. However when we looked at perception of odors from males in different age categories based on the age of the female scent recipient (sniffer), some interesting patterns emerged. The age of the female scent recipients significantly correlated with their perception of the intensity and spiciness of males at their sexual prime (18-29 age category).  There was an even stronger relationship between the women’s ages and their responses to all scent categories (familiarity, intensity, pleasantness, spiciness and sexiness) of males in the fifty and over category. There was also a strong relationship between a woman’s level of sexual activity and her perception the pleasantness of male body odors in both the 18-29 and 50+ age categories.  Perception of the sexiness of male body odors in the 30-39 and 50+ age categories, as well as the intensity of male odors in the 30-39 age categories and the familiarity of odors from the males in the 50+ age category was also related to the degree of sexual activity in the female scent recipients. These results suggest that women of different ages respond differently to men of different ages in response to their body odors. They also lend support to the theory that sexual selection tends to cause women to prefer older, more established mates.
