    This study investigates the relationship between serum total testosterone levels and glucose metabolism in normal-weight Japanese women.

  • 2

    Significant inverse correlations were found between total testosterone levels and HbA1c, fasting glucose, and HOMA-IR.

  • 3

    The inverse associations with HbA1c and fasting glucose remained significant after adjusting for BMI and lifestyle factors.

  • 4

    The association between total testosterone and HOMA-IR remained significant after adjusting for age and menopausal status.

  • 5

    The findings suggest that maintaining physiological testosterone levels may be important for glucose metabolism in normal-weight women.
