With the help of 3D facial photography, the results showed a significant relationship between a high level of prenatal testosterone and masculinization of male and female adult facial features.Īnother study regarding facial metrics and testosterone levels showed that men have five times baseline testosterone concentrations. This study was a 25-year research masterpiece wherein an assessment of the umbilical cord’s testosterone level correlated with how the individual looked like in the future. 2015 showed an association between prenatal testosterone levels to postnatal facial features. This outcome showed that testosterone served to help catch up those experiencing delays in pubertal growth.Įxciting research by Whitehouse et al. A comparison with the two groups after a year showed almost no significant difference in the craniofacial growth between the two groups. The boys on testosterone treatment for one year showed an increase in overall mandibular length, ramus length, and total anterior face height. The results of this study showed that a delay in puberty affects the craniofacial growth of an individual. The purpose of low-dose testosterone treatment is to instigate a growth spurt. The study focused on a group of 14 years olds who had delays in puberty to 12-14 years old who had a healthy development. Their research centered on the effects of low-dose testosterone treatment on boys’ craniofacial growth with delayed puberty. One good example of this is a study by Verdonck et al. There’s a lot of research supporting that testosterone affects the growth of the jaw. Testosterone affects the whole body, but we will focus on how it affects jaw growth and the rest of the facial structure for purposes of this article. This is true even for females with high in-utero testosterone exposure. Testosterone also creates masculine features such as a broader nose, thicker brows, and thin lips. Men with high testosterone levels will have a more square jawline, large mandible, and larger overall mandibular length, ramus length, and total anterior face height. Testosterone also affects the development of bones and muscles, especially on the facial features of men. It brings about several changes to the male body, such as: deepening of the voice, increasing sex drive, and increasing production of sperm. Testosterone is a sex hormone that either the testicles or the adrenal gland releases.
