title: Salivary testosterone levels and autism-spectrum quotient in adults.
abstract: OBJECTIVE
  The purpose of this study is to examine the relationship between salivary testosterone levels and autistic traits in adults.
  
  
  METHODS
  A total of 92 male and female adults participated in the present study. Their salivary testosterone level (T) and score of Japanese version of Autism-spectrum Quotient (AQ) were assessed to examine the relationship between salivary testosterone level and autistic traits in adults.
  
  
  RESULTS
  We observed a positive correlation between T and AQ in a group of both sexes. The correlation disappeared when we conducted correlation analysis by sex. However, although there was no sex difference in the score of the subscale of attention switching, attention switching was related to T.
  
  
  CONCLUSIONS
  Although the relationship between T and AQ may mainly result from sex differences, the subscale of attention switching may be modulated by testosterone.
