Introduction: Decreased bone mineral density (BMD) in Klinefelter syndrome (KS) is frequent and it has been traditionally related to low testosterone levels. However, low BMD can be observed also in patients with normal testosterone levels and testosterone replacement therapy does not necessarily increase bone mass in these patients. Nothing is known about vitamin D levels and supplementation in KS. In this study we determine vitamin D status and bone mass in KS subjects and c...

Introduction: Testicular cancer (TC) is the most common cancer in white males aged 20–40 years, with a worldwide incidence of 7.5/100.000. Recently, we demonstrated an association between testiculopathy and alteration of the bone status, despite conserved bone-sparing effects of androgens and estrogens. Furthermore, recent published data from our group documented a strong reduction in 25(OH)D plasma levels in bilaterally orchiectomized patients compensated by testosterone...
