OBJECTIVE: To study and establish sex hormone cutoff levels for osteoporosis risk in men over 50 years old. METHODS: Case-control study of 216 men > 50 years, 110 with osteoporosis (O) and 106 with normal bone density (C). We measured estradiol (E2), sex hormone binding globulin (SHBG), total testosterone (TT) and albumin. Free testosterone (FT) and bioavailable testosterone (BT) were calculated through Vermeulen’s formula. RESULTS: There was no difference in TT between groups. Relative risks of osteoporosis were 1.89 for […]

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 […]
