The Science Behind Mate Selection: Axillary Sweat and Pheromones

• Axillary sweat is believed to provide a “chemical signature” that humans and even breastfed infants can identify.
• Studies suggest that mating may be disassortative in regards to the major histocompatibility complex (MHC) genotype, where individuals prefer mates with dissimilar MHC-genotypes.
• Preliminary studies suggest pheromones play a role in mate selection through the attribution of attractiveness, as evidenced by speed-dating experiments and correlations between women's preference for masculine faces for long-term relationships and their pleasantness rating of certain pheromones.

Have you ever wondered what draws us to one person over another when it comes to mate selection? Well, as it turns out, there’s a science behind the attraction. In this blog post, we’ll explore how axillary sweat and pheromones play a role in mate selection.

What is Axillary Sweat and Pheromones?

Axillary sweat is the secretion of sweat through the pores in our armpits. It contains proteins and fatty acids, which can be used by bacteria on our skin to generate odorous compounds known as axillary pheromones. These compounds are secreted from the body and can affect others around us on both conscious and subconscious levels, influencing behavior in subtle ways.

Importance of Axillary Sweat in Mate Selection

The Chemical Signature Theory suggests that humans use axillary sweat as a way to recognize potential mates who have compatible immunological profiles. This means that we are drawn to people whose genetic makeup is different from our own—but not too different. This is known as the Major Histocompatibility Complex (MHC) Genotype Preference Theory. There is evidence that MHC-dissimilarity has an effect on mating preferences among human couples as well as other species such as mice and voles.

Role of Pheromones in Mate Selection

Pheromones play an important role in mate selection too; studies have shown that certain pheromones influence our perceptions of attractiveness, particularly those related to female fertility. For example, speed-dating experiments show attraction toward dissimilar MHC-genotypes among women who rated men with high pleasantness ratings for certain pheromone compounds. Other research has demonstrated a correlation between pleasantness rating of certain pheromone compounds and women’s preference for masculine faces for long-term relationships or short-term flings with attractive men.

In conclusion, while there may be many factors involved in mate selection, it seems clear that axillary sweat and pheromones play an important role in determining whether or not someone finds another person attractive or desirable for a relationship. As we learn more about these hidden forces at work within us all, we may gain greater insight into why some relationships succeed while others fail—and how we can make better decisions when it comes to choosing a partner for life!
