Summary
We describe a 16-year-old boy with idiopathic hypogonadotropic hypogonadism associated with osteoporosis. Osteoporotic lesions of the hands, skull and spine were shown by routine radiography. Single-photon absorptiometry at the distal radius confirmed a significant reduction of bone mineral density. The parathyroid hormone-vitamin D axis and calcitonin secretion showed no derangement. Reduced bone mineral density in association with relatively elevated levels of serum osteocalcin and alkaline phosphatase suggested an increased bone turnover (so-called high-turnover osteoporosis). Tetosterone therapy for 3 months significantly increased the radial bone mineral density.
This case illustrates that testosterone deficiency during puberty seems to alter the bone mineral status, impairing bone mineralization and bone remodeling.
