In this study, researchers give hepatitis B vaccine to young women 52 Latvian origin, as well as measuring the amount of antibodies produced participants. Researchers also check the levels of the hormone cortisol which participants indicated their level of stress.
Then a team of researchers led by Markus Rantala of the University of Turku, Finland was photographing the participants were an average age of 20 years are then asked 18 heterosexual male volunteers to assess the participants' facial attractiveness. From there, researchers tried to find a link between facial attractiveness participant with his immune system response.
"In contrast to men, we found that the female immune response (eg, the ability to produce antibodies) apparently can not be attributed to his appeal," said Dr. Rantala as reported by the Daily Mail
"But because the immune system itself is so complex it is still too early to tell if a pretty face is not showing signs of a strong immune system in women. Maybe facial attractiveness in women showed differences in potential immunity to men, although this still needs to be confirmed again , "he added.
Studies conducted by Dr.. Rantala was also found that facial attractiveness in women does not indicate the level of immune response when faced woman with hepatitis B but more attributed to two aspects of long-term health and fertility, including setting the levels of the stress hormone cortisol and body fat percentage.
Only when the researchers looked at the participants' cortisol levels, they found that both men and women alike look unattractive when subjected to stress.
This study reports recently published in the journal Biology Letters.
