Risk of Late-Onset Hypogonadism (Andropause) in Brazilian Men over 50 Years of Age with Osteoporosis: Usefulness of Screening Questionnaires

Objective: To analyze the relative risk of late-onset hypogonadism in men with osteoporosis and the usefulness of screening questionnaires. Methods: We correlated the Aging Male's Symptoms (AMS), Androgen Deficiency in Aging Male (ADAM) and International Index of Erectile Function (IIEF-5) questionnaires and the laboratory diagnosis of hypogonadism in 216 men aged 50-84 years (110 with osteoporosis and 106 with normal bone density, paired by age and ethnicity). Results: Hypogonadism presented in 25% of the osteoporotic and in 12.2% of normal bone density men (OR 2.08; IC95%: 1.14-3.79) and was associated with ADAM first question (low libido, p=0.013). Levels of TT below 400 ng/dl correlated with an AMS score above 26 (p=0.0278). IIEF-5 showed no correlation with testosterone levels. Conclusion: Hypogonadism was 2.08 times more prevalent in osteoporotic men. The symptom that best correlated with late-onset hypogonadism was low libido (ADAM 1 positive).
