Abstract:
Materials and Methods: We studied 114 healthy males aged above 40 years old, who undergone urologists examination and General practitioner. All men answered the Aging Males’ Symptom Scale questionnaire. This is part of the ongoing study Mongolian males Andrological Status sponsored by Asian Research center, Korean Foundation for Advenced Studies. Formal concent permission was obtained from all participants, which approved by Ethical Committee of MoH. We took 4 ml blood from vien between 8-11am and determined testosterone, SHBG by ELISA and albumin by liquicolor reagent. Bioavailable testosterone was calculated, using previously described mathematical modeling, suggested by ISSAM.Result: The average free testosterone level was 0.112±0.06 ng/ml, in 40-49 age group 0.124±0.05 ng/ml, in 50-59 age group 0.114±0.07 ng/ml, in 60-69 age group 0.107±0.07 ng/ml, and over 70’s it was 0.097±0.04 ng/ml. If consider the free testosterone 100%, in 40-49 age than it is decreasing 91.6% in 50-59, 83.3% in 60-69 ages and 75% decreased in over 70s. Respectively, it decreases approximately by 0.8% every year after 40’s.Conclusion: The free testosterone level was 0.11±0.06 ng/ml in aging males and has reverse correlation with aging (r=-0.168, p= 0.03).
