Permanent and bulging breasts are unique to the female of the human species and are not observed in other mammalian and primate species. Permanent breasts, a sexually dimorphic feature, reflect the level of body feminization that is also related to puberty sex hormones. Recent studies show that estrogen / testosterone levels during puberty are also responsible for facial development. There are findings that the increased testosterone / estrogen balance increases the transverse development of the face. The aim of this study is to test whether there is any relationship between relative face width, which is considered to be the physical marker of feminization levels, and breast size. 135 female students (mean age = 22.2, SD = 2.02) studying at the university were analyzed in the study. Measurements were made while the subjects were naked, and the chest circumference passing from the tip of the breast and directly under the breast was measured to determine the breast size. Relative face width was calculated by taking the ratio of face width (zygion-zygion) to upper face length (nasion-prosthion). The average breast size of the girls in the study group is 10.50 cm (min = 3.10, max = 21.0, SD = 3.58), and their relative face width is 1.90 (min = 1.53, max = 2.22, SD = 0.14). According to the partial correlation analysis results, no significant relationship was observed between breast size and relative face width. This finding suggests that the effect of estrogen levels on relative face width is doubtful.
