Abstract The development of digits is under the control of Hox genes, which also control the differentiation of the urogenital system. In the present study we evaluated the association between penile length and lengths of the second and fourth digits. Materials and methods: In this study, 1028 Turkish male primary school children from the Eastern Mediterranean Region of Turkey were included. Weight and height measurements were obtained in order to calculate the body mass index (BMI). Flaccid and stretched length of the penis was measured. The lengths of the second and fourth digits of the right hands were measured. Statistical analyses were performed with descriptive statistics and Pearson correlation analysis. Results: A significant correlation was found between the following parameters: the length of the second digit with flaccid and stretched length of the penis (r = 0.166 and r = 0.276, respectively; P < 0.01); and the length of the fourth digits with flaccid and stretched length of the penis (r = 0.174 and r = 0.287, respectively; P < 0.01). No significant correlation of 2D:4D ratio was found with flaccid and stretched length of the penis (r = -0.013; P = 0.668, r = -0.018; P = 0.565, respectively). Conclusion: The positive correlations in our study are a novel finding and may have further clinical implications.

Abstract

The development of digits is under the control of Hox genes, which also control the differentiation of the urogenital system. In the present study we evaluated the association between penile length and lengths of the second and fourth digits. Materials and methods: In this study, 1028 Turkish male primary school children from the Eastern Mediterranean Region of Turkey were included. Weight and height measurements were obtained in order to calculate the body mass index (BMI). Flaccid and stretched length of the penis was measured. The lengths of the second and fourth digits of the right hands were measured. Statistical analyses were performed with descriptive statistics and Pearson correlation analysis. Results: A significant correlation was found between the following parameters: the length of the second digit with flaccid and stretched length of the penis (r = 0.166 and r = 0.276, respectively; P < 0.01); and the length of the fourth digits with flaccid and stretched length of the penis (r = 0.174 and r = 0.287, respectively; P < 0.01). No significant correlation of 2D:4D ratio was found with flaccid and stretched length of the penis (r = -0.013; P = 0.668, r = -0.018; P = 0.565, respectively). Conclusion: The positive correlations in our study are a novel finding and may have further clinical implications.
