Background: Parathyroid hormone-related protein (PTHrP) was discovered as a tumor product. It is also one of the complex epithelial and mesenchymal interaction signal mediator in breast development. An increase in the prevalence of malignancy in patients with Klinefelter’s syndrome, but not in patients with idiopathic gynecomastia has been previously reported. PTHrP may play a critical role in the development or progression of breast cancer.Aim: We ...

Introduction: The evidence shows that the prevalence of metabolic syndrome is increased in patients with hypogonadism. However, much of the data regarding this association comes from the elderly patients with obesity, hypertension or type 2 diabetes. The total testosterone levels alter physiologically in these conditions and thus can falsify the association. We aimed to investigate the prevalence of the metabolic syndrome in young adults with hypogonadism who do not have any c...

The high-density lipoprotein (HDL) levels are decreased in paitents with hypogonadotropic hypogonadism (HH). Although testosteron regulates lipoprotein metabolism, the effect of testosterone replacement therapy on HDL metabolism is not clearly shown in HH. The aim of this study is to determine the effects of testesterone replacement on HDL subfractions in young patients with HH. Forty-three cases with HH (mean age 21±2.45 years) were enrolled. Fifty-one healthy volunteer ...

Background: Idiopatic hypogonadotropic hypogonadism is a congenital abnormality due to GnRH deficiency which is associated with severe osteoporosis. Testosterone replacement has been shown to improve the loss in the bone mass. The aim of the present retrospective analysis was to measure the effect of human chorionic gonadotropin treatment on the improvement of bone mineral density.Methods: A total number of 96 young male (mean age 21±3.7 years) pati...

Objective: Metabolic disorders are common in patients with hypogonadism. Testosterone replacement therapy (TRT) significantly improves symptoms of testosterone deprivation such as mood, libido or musculoscelatal power. However, whether the metabolic and cardiovascular risk is improved is not clearly known. We aimed to search for the metabolic and cardiovascular effects of TRT.Design: Prospective study, performed in the outpatient units of Gulhane Medical...

Metabolic disorders and cardiovascular events are increased in hypogonadism. Serum HDL composition is a better cardiovascular predictor than the HDL counts. However, there is no information about the HDL subfractions in patients with hypogonadism. We designed a prospective study to investigate the HDL subfractions in treatment naïve subjects with hypogonadism and the effects of two different testosterone replacement regimens on the HDL subfractions. Seventy young male pat...
