The purpose of this study was to determine average penile length and to investigate the relationship between penile length and somatometric parameters in a group of young, healthy Turkish men. A total of 1,132 men were included in the study. The age, height and weight of the subjects were recorded. Penile length was measured in both flaccid and stretched states. The correlation between penile length and somatometric parameters was analysed. The mean age of the subjects was 20.3±0.9 years. The mean penile length in flaccid and stretched states was 9.3±1.3 and 13.7±1.6 cm, respectively (P<0.001). There was a positive correlation between flaccid and stretched penile length (r=0.800, P<0.001). The mean testicular volume was 22.0±2.8 cm(3). A weak positive correlation was detected between penile length and mean testicular volume (r=0.143 for flaccid penile length and r=0.140 for stretched penile length, P<0.001 for both). Similarly, weak positive correlations were found between penile length (both flaccid and stretched) and height, weight and body mass index, respectively (P<0.001, for all). These results demonstrate that somatometric parameters are correlated with penile length. We believe that further studies would provide more information about the causal relationship.
本研究旨在确定一组年轻、健康的土耳其男性的平均阴茎长度，并探讨阴茎长度与人体测量参数之间的关系。共有 1132 名男性纳入研究。记录受试者的年龄、身高和体重。测量阴茎在松弛和伸展状态下的长度。分析阴茎长度与人体测量参数之间的相关性。受试者的平均年龄为 20.3±0.9 岁。松弛和伸展状态下的平均阴茎长度分别为 9.3±1.3 和 13.7±1.6cm（P<0.001）。松弛和伸展状态下的阴茎长度呈正相关（r=0.800，P<0.001）。平均睾丸体积为 22.0±2.8cm(3)。松弛和伸展状态下的阴茎长度与平均睾丸体积之间均存在弱正相关（r=0.143 和 r=0.140，均 P<0.001）。同样，阴茎长度（松弛和伸展状态下）与身高、体重和体重指数之间也存在弱正相关（均 P<0.001）。这些结果表明人体测量参数与阴茎长度相关。我们认为进一步的研究将提供更多关于因果关系的信息。
