Mate Selection Chemistry

Women want a man with the right chemistry.

Men use their eyes mostly to select a mate. And it appears that "love is blind" in many cases! Women use their nose mostly! That may explain why some beautiful women are with such dorky looking guys. I guess they just smell good!

Recent research reveals women are more influenced by how a man smells than how he looks. It is all done unconsciously and is based on the subtle chemical odors related to men's immune system. Women instinctively are attracted to men with an immune system most different to their own. Evolutionarily, this has proven to be the best combination for strong health and best survival of offspring. This also explains why young women are so turned-off by their brothers!

Scientists have identified a range of subtle chemicals and odors associated with men's immune system. These odors, called pheromones, are secreted by men's skin. In tests, women were able to use these pheromones to sort men with similar immune systems from men with very different immune systems. They did this even when the chemical odors were not detectable consciously. Men could not do the same test and scored the same as if flipping a coin.

The evolutionary wisdom in women's heightened smelling ability is evident. Historically, women who selected men with the most different immune system produced children with an immune system that had the most defenses against the hazards to good health and survival.

The research also reveled that women's sexual attraction to their selected man is modulated by his odors. This means women's chemistry is therefore controlled and stimulated -- or not -- by how the man smells! Research also revealed that women married -- or in long term relationships with men who had immune systems similar to their own -- actually did have, or at least thought about having, sex with other men than their mate. The high degree of satisfaction with a marriage or long term relationship correlated with big difference in immune systems. The most dissatisfied couples had the most similar immune systems. The statistical evidence was only in women.

Women's selection criteria is in their genes.

The ability to detect a male with a very different immune system by his odor is unique to females. This difference between men and women lies in a strip of genes, called Major Histocompatibility Complex (MHC), that control cells making proteins used in recognizing virus, bacteria, pollen and dangerous substances. It appears women, and many female animals, can unconsciously detect the amount and strength of these proteins in males. These proteins detected in males stimulated the females' sexual attraction and drive. Researchers warn that this is not the only criteria females use to select a male for a mate but it appears to be one important decider that has been strengthened in female's evolutionary process.

Advice for men.

Understand that if that perfect woman you just met is turned off by you, maybe you just don't have an immune system different enough from hers! If that is the case, there is still something you can do to be more appealing. Most women find a man appealing who uses a light spray or deodorant such as ocean breeze, kiwi, or a combination of baby powder and chocolate. The smell of a man's clean skin with a little fresh sweat, combined with fresh fruity scents, is the strongest stimulant for most women.

Fact 8:
Women have a keen sense of smell and use it unconsciously to help select their best mate.

A woman's "best mate" is one who has an immune system very different than her own. The combination of their two different immune systems will give their children the best chances for survival with maximum defenses against infections and diseases.
