Testosterone levels to a fetus in the womb is exposed male can determine your face will look as an adult, according to a study released Wednesday in Australia <. /> p>
“High levels of testosterone in the cord are actually linked to more masculine facial features,” said Andrew Whitehouse, University of Western Australia and co-author of this research, links first exposure prenatal testosterone and the structure of a face.
Previous studies claimed that levels of testosterone during puberty were the ones who determined the male characteristics and female in a person, but the new study emphasizes that are most important during the prenatal stage.
“We also measured hormone levels during puberty and we found that prenatal levels were more related to the male facial structure, “he said Whitehouse was quoted by the local ABC.
For this study, published in the journal Proceedings of the Royal Society B, scientists followed the development of thousands of Children born to mothers who were recruited for the study during pregnancy.
Then they analyzed the levels of testosterone in the umbilical cords of 97 men and 86 women in your body at different stages of his life.
Once the target group met between 21 and 24 years, scientists analyzed how men wore their faces and discovered the link between levels testosterone in the umbilical cord and the masculinity of the face.
“If we see women, will see that those who had more testosterone male characteristics have also ” said Whitehouse .
The criteria of masculinity were determined through twelve measures linked to facial “landmarks” as the size of the nose, the distance between the eyes, thick eyebrows.
For researchers, genetic influences the presence of a higher level of testosterone in the womb , but must also take into account other factors such as chemical or even overweight.
