There are some facts and theory's already present with the masculinity of a person and testosterone levels. But what about their appearance, is a connection present? Well there may be a slight break through in the testosterone levels at birth and their changes during puberty to becoming adults.
A study by Andrew Whitehouse and colleagues at the University of Western Australia may of had made the link. They had initially used umbilical cord blood collected from birth as part of a long term study. They asked the 183 former newborns (which are now in their late twenties) to visit the lab and have 3D infrared images made of their faces. They was able to take note of the relative points that the nose, lips and eyes were in; they then judged their facial structure as being more masculine or feminine and compared this to the testosterone concentration inside that person's umbilical cord blood.
The results concluded that the people with the more masculine looking faces, both male and female had high levels of testosterone in their umbilical cords blood. However; what is strange is that they tested the levels of testosterone levels in men as adults, but results showed that there was no connection with the masculinity of their faces and levels of testosterone.
