No Evidence for Associations between men's Salivary Testosterone and Responses on the Intrasexual Competitiveness Scale.

ABSTRACT:

Objectives

Many previous studies have investigated relationships between men's competitiveness and testosterone. For example, the extent of changes in men's testosterone levels following a competitive task predicts the likelihood of them choosing to compete again. Recent work investigating whether individual differences in men's testosterone levels predict individual differences in their competitiveness have produced mixed results.

Methods

In light of the above, we investigated whether men's (N?=?59) scores on the Intrasexual Competitiveness Scale were related to either within-subject changes or between-subject differences in men's salivary testosterone levels.

Results

Men's responses on the Intrasexual Competitiveness Scale did not appear to track within-subject changes in testosterone. By contrast with one recent study, men's Intrasexual Competitiveness Scale also did not appear to be related to individual differences in testosterone.

Conclusions

Our results present no evidence for associations between men's testosterone and their responses on the Intrasexual Competitiveness Scale.

Project description:INTRODUCTION:Recently, testosterone (T) has been shown to be associated with premature ejaculation (PE) symptoms in the literature. Furthermore, studies suggest that the etiology of PE is partly under genetic control. AIM:The aim of this study was to reassess findings suggesting an association between testosterone (T) and a key symptom of PE, ejaculation latency time (ELT), as well as exploratively investigating associations between six androgen-related genetic polymorphisms and ELT. MATERIALS AND METHODS:Statistical analyses were performed on a population-based sample of 1,429 Finnish men aged 18-45 years (M = 26.9, SD = 4.7). Genotype information was available for 1,345-1,429 of these (depending on the polymorphism), and salivary T samples were available from 384 men. Two androgen receptor gene-linked, two 5-alpha-reductase type 2-gene-linked, and two sex hormone-binding globuline gene-linked polymorphisms were genotyped. MAIN OUTCOME MEASURES:Ejaculatory function was assessed using self-reported ELT. RESULTS:We found no association between salivary T levels and ELT. We found a nominally significant association between a 5-alpha-reductase type 2-gene-linked polymorphism (rs2208532) and ELT, but this association did not remain significant after correction for multiple testing. One single nucleotide polymorphism in the sex hormone-binding globulin gene (rs1799941) moderated (significantly after correction for multiple testing) the association between salivary T and ELT, so that A:A genotype carriers had significantly lower salivary T levels as a function of increasing ELT compared with other genotype groups. CONCLUSIONS:We were unable to find support for the hypothesis suggesting an association between T levels and ELT, possibly because of the low number of phenotypically extreme cases (the sample used in the present study was population based). Our results concerning genetic associations should be interpreted with caution until replication studies have been conducted.
