Summary The European Male Aging Study ( EMAS ) has recently defined strict diagnostic criteria for late‐onset hypogonadism ( LOH ) including the levels of serum total testosterone ( TT ), free testosterone ( FT ) and three sexual symptoms. However, there is no report on risk factors for LOH using these criteria. In this study, we investigated risk factors for LOH based on these criteria. We recruited 277 men (aged 36‐80 years) who completed both a health check‐up and two questionnaires (a health and lifestyle questionnaire, and a sexual function questionnaire). Data on parameters, such as systolic blood pressure ( SBP ), glucose, triglyceride ( TG ) and high‐density lipoprotein ( HDL ), were obtained from medical records of the hospital in Shantou. TT and sex hormone‐binding globulin ( SHBG ) were measured by chemiluminescent immunoassay, and FT was calculated. TT , FT , age, waist circumference, SBP and glucose showed significant differences between LOH ‐positive and LOH ‐negative individuals. Univariate regression analyses showed that age, waist circumference, SBP , glucose and health status were risk factors for LOH . Pearson's correlation analysis revealed that TT was inversely correlated with waist circumference, glucose and SBP , and FT was inversely correlated with age, SBP and health status. In conclusion, age, waist circumference, SBP , glucose and health status were risk factors for LOH .
