title: Androgen supplementation in eugonadal men with osteoporosis-effects of 6 months of treatment on bone mineral density and cardiovascular risk factors.
abstract: This open, prospective therapeutic trial studied the effects of regular moderate androgen supplementation on bone mineral density in eugonadal men with established osteoporosis, and collected data on the safety of androgen therapy used in this setting. 23 men, aged 34-73 years, with vertebral crush fractures and back pain, in whom secondary causes of osteoporosis had been excluded, were treated with fortnightly intramuscular injections of 250 mg testosterone esters (Sustanon 250(R)) for 6 months. Blood pressure was recorded monthly; fasting lipids, glucose, haematocrit, plasma viscosity, and testosterone levels were measured every 3 months. Psychological effects were assessed using the Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ), together with questioning on libido changes. Principal outcomes measured were changes in bone mineral density at the hip and spine by dual-energy X-ray absorptiometry (DEXA) over the treatment period. 21 men completed the study period. Mean bone mineral density at the lumbar spine increased from 0.799 g/cm(2) to 0.839 g/cm(2) during treatment (p < 0. 001), a rise of 5% in 6 months. Bone mineral density at the hip did not change. There were significant, favorable changes in diastolic blood pressure (-4.7 mmHg, p < 0.01), serum triglyceride levels (-0.405 mmol/L,p < 0.01), and total cholesterol (-0.27 mmol/L, p < 0.05). Adverse changes included a fall in HDL cholesterol (-0.087 mmol/L, p < 0.05) and a rise in plasma viscosity which was significant at 3 months but not at 6 months. The expected rises in hematocrit (0.434 to 0.456) and FAI (0.504 to 0.887) occurred. We conclude that testosterone supplementation significantly increased bone mineral density in this heterogeneous group of men with idiopathic primary osteoporosis, without an overall adverse effect on cardiovascular risk factors. This treatment warrants further evaluation in a randomized, controlled trial.
