  • Title: Sensation seeking, sexual curiosity and testosterone in inmates.
    Author: Aluja A, García LF.
    Journal: Neuropsychobiology; 2005; 51(1):28-33. PubMed ID: 15627810.
    Abstract:
    The relationships between sensation seeking, curiosity about sex, and total and free testosterone in inmates were investigated. The role of other hormones such as luteinizing hormone (LH), follicle-stimulating hormone (FSH), and sex hormone-binding globulin (SHBG) in these relationships was also analyzed. Previous analysis allowed the deletion of extreme hormone values affecting the distribution of the variables. In spite of obtaining a high mean for SHBG, relationships between hormones were appropriate. It was observed that higher values of SHBG produce an increment in total testosterone, but not in free testosterone. Positive relationships between total testosterone and the Disinhibition scale of the Sensation Seeking Scale Form V were replicated, although they were affected by SHBG. Significant relationships between total and free testosterone and curiosity about sex were also found. LH and FSH did not influence these patterns of relations. It was suggested that relationships between SHBG and sensation seeking in inmates could be mediated by items referring to alcohol and drugs. The high levels of SHBG observed in the sample reinforced this suggestion. In spite of the role of SHBG, subjects who were desinhibited and concerned about sex presented higher concentrations of total and free testosterone. The results support Zuckerman's sensation seeking theory.
