One thousand cases of males aged 40-70 years were investigated. The aging male symptoms （AMS） scale and androgen deficiency in aging males （ADAM） questionnaire were used at the beginning of the investigation, followed by measurement of the sex hormone-related factors （total testosterone （TT）, free testosterone （fT）, sex hormone-binding globulin （SHBG） and bioavailability of testosterone （Bio-T））. There were 977 valid questionnaires. The LOH-positive rates shown by AMS and ADAM were 59.88% and 84.65%, respectively; values increased with the age of the patients. There were 946 results related to sex hormone measurements, which showed the following results： TT was not related to aging （P〉O.05）; levels of SHBG increased with age; and fT and Bio-T decreased with age. There was a significant difference in fT between LOH-positive and LOH-negative patients, as shown by the ADAM. In summary, TT levels were not related to aging, even though SHBG did increase while fT and Bio-T decreased with aging. Clinically, the diagnosis of LOH cannot be based on serum TT level.展开更多
