Abstract:
Introduction: With the increasing longevity in men and women, sexual health concerns have become more and more important and demands for help are far more common than in the past. The percentage of aging population is increasing also. The of this study in aging men. Late onset hypogonadism will need the testosterone replacement therapy and we hope that our study result will help to get basic information of testosterone among over 40 yearsold Mongolian men.Goal: To determine the bioavailable testosterone (BT) of aging males and correlate with aging process.Materials and Methods: This study is a part of ongoing study: “Androgen status of aging males” which was supported by Asian Research Center, Korean Foundation for Advanced Studies. We studied 114 healthy males aged above 40 years old, all undergone the General and Urological examination. Bioavailable testosterone was determined by formula suggested by ISSAM.Result: The average bioavailable testosterone level was 2.53±1.48 ng/ml, in 40-49 age group 2.76±1.37 ng/ml, in 50-59 age group 2.60±1.70 ng/ml, in 60-69 age group 2.51±1.56 ng/ml, and over 70’s it was 2.04±1.05 ng/ml. If consider the bioavailable testosterone 100%, in 40-49 age than it is decreasing 94.2% in 50-59, 90.9% in 60-69 ages and 73.9% decreased in over 70s. Respectively, it decreases approximately by 0.9% every year after 40’s.Conclusion: The bioavailable testosterone level was 2.53±1.48ng/ml in aging males and has reverse correlation with aging (r=-0.169, p=0.037).
