Short stature, decreased muscle mass (hypotonia), increased body fat, decreased bone mineral density and other somatic abnormalities are major causes of morbidity and social limitation in individuals with Prader-Willi syndrome. Detailed studies indicate that two major endocrine pathologies may account for many of these somatic abnormalities. A true deficiency of the growth hormone (GH)-insulin-like growth factor axis is a principal cause of the short stature and is probably a major contributor to the decreased muscle mass and osteopenia. Hypogonadotropic hypogonadism is the probable primary cause of osteopenia and osteoporosis. No other endocrine abnormalities have been specifically identified in Prader-Willi syndrome, although there may be increased risks of premature adrenarche and type 2 diabetes mellitus, both secondary to obesity. GH replacement therapy is effective in normalizing linear growth and also has positive effects on muscle mass and function, and on bone mineralization. Judicious gonadal steroid replacement may be effective in treating the osteopenia and preventing osteoporosis. GH and gonadal steroid replacement therapy should be considered for all patients with Prader-Willi syndrome.

It has recently been demonstrated that > or = one-third of men with type 2 diabetes mellitus have low testosterone concentrations associated with inappropriately low luteinizing hormone and follicle-stimulating hormone concentrations. Hypogonadotropic hypogonadism in men with type 2 diabetes is associated with obesity but not duration of diabetes, elevated glycosylated hemoglobin, or the presence of microvascular complications of diabetes. Recent data show that hypogonadotropic hypogonadism is also observed frequently in nondiabetics with the metabolic syndrome or obesity, but it is not associated with type 1 diabetes. Low testosterone concentrations in men with type 2 diabetes have also been related to a higher C-reactive protein concentrations, lower hematocrit, increased total and regional adiposity, lower bone mineral density, and erectile dysfunction. This article discusses the pathophysiology of hypogonadotropic hypogonadism in men with type 2 diabetes and its signs and symptoms. Clinical trials are required to determine whether testosterone replacement therapy alleviates insulin resistance, inflammation, and symptoms related to sexual dysfunction care.
