OBJECTIVE: To assess the efficacy and safety of testosterone replacement in males with late-onset hypogonadism compared to hypogonadal men without replacement, and controls, during six months. METHODS: We assessed, through ADAM, AMS, IIEF-5 and SF-36 questionnaires, and through clinical and laboratorial examinations, 62 patients divided into three groups: 17 hypogonadal males (HR) used intramuscular testosterone every three weeks; 14 hypogonadal males (HV) and 31 non-hypogonadal males (CV) used oral vitamins daily. RESULTS: When compared to others, HR group obtained libido […]

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 […]

OBJECTIVES: To evaluate which factors influence the laboratorial diagnosis of late-onset male hypogonadism (LOH). METHODS: Total testosterone (TT), SHBG and albumin were measured in 216 men aged 52-84 years. The laboratorial definition of LOH was two values of calculated free testosterone (cFT) <6.5 ng/dl, according to Vermeulen’s formula. RESULTS: At the first blood test, cFT was <6.5 ng/dl in 27% of the men. Laboratorial LOH (confirmed by two tests) was present in 19%, but TT levels were low in only […]
