March 5th, 2012

With George Clooney at the Venice Film Festival in August 2008.Men might wonder why women drool over the likes of Brad Pitt or George Clooney but their attraction might be for the immune system of these guys rather than the pretty faces and six pack abs.

Men who have more testosterone appear to be more attractive hunks, and they too have stronger immune systems. This was according a recent study published in Nature Communications. The research concludes that women are attracted to the macho look because the manly features also signal a very good health.

Researchers from Abertay University had 74 male subjects in their twenties who gave samples of blood for evaluation. The blood samples were collected about a month after getting a vaccine for Hepatitis B which triggers the release of anitbodies. The levels of antibodies and testosterone were measured plus the level of cortisol which is a stress hormone.

The next step of the study involve women rating photographs of the men involved in the research. The photos were rated based on a 10 point scale which ranks attractiveness. The proponents of the study then tried to find links between the ratings and the male level of antibodies, attractiveness, and hormones.

Scientists found out that the higher level of testosterone were found on male subjects with sexier faces and stronger immune systems. The men who were rated by the women as most attractive were those with the best responding immune systems compared to those with weaker immune system. The hotness and testosterone levels of the attractive men were also linked to lower levels of their stress hormones which suggest than stress has bad effects on the immune system and how women rate attractiveness.

This study was the first to establish that looks of men is correlated with their immune system and with how women see them as attractive.
