Male Adolescents' Sexual Behavior and the Role of Testosterone

Objectives Given the paucity of studies focusing on testosterone (T) and adolescent sexuality, and their conflicting findings, we aimed to empirically address two competing conceptualizations of the link between T and sexual behavior in adolescence: (1) the T as sexual motivator and (2) the T as competition-sensitive sexual motivator models. Methods The study used data from a longitudinal study of 252 male Croatian adolescents who provided a saliva sample at the final data collection wave (at the age of 18). Applying multivariate statistical procedures, we tested links between salivary T levels and a range of partnered and non-partnered sexual behaviors-partly in retrospect. Results Only one significant association emerged-a robust link between T at the age of 18 and the number of lifetime sexual partners. Considering the evidence that multiple sexual partners can enhance male adolescents' social status, our findings support the T as competition-sensitive sexual motivator model. Conclusions Although this study could not distinguish between direct and indirect influences of T on adolescents' sexuality, it confirmed the value of biopsychosocial approach to adolescent sexuality.
