BACKGROUND Delayed puberty can result either from constitutional delay of growth and puberty (CDP) or idiopathic hypogonadotropic hypogonadism (IHH). Gonadotropin-releasing hormone (GnRH) stimulation test has been generally accepted as a current method for diagnosing delayed puberty. The objective of this research was to assess the cut-off values and the efficacy of GnRH stimulation test in the...

Hemochromatosis is a disease caused by extraordinary iron deposition in parenchymal cells leading to cellular damage and organ dysfunction. β-thalassemia major is one of the causes of secondary hemochromatosis due to regular transfusional treatment for maintaining adequate levels of hemoglobin. Hypogonadism is one of the potential complications of hemochromatosis, usually seen in patients with ...

Our goal in the present work was to determine whether male patients with untreated hypogonadism have an increased risk of developing rheumatic/autoimmune disease (RAD), and, if so, whether there is a relation to the type of hypogonadism. We carried out neuroendocrine, genetic, and rheumatologic investigations in 13 such patients and 10 healthy male 46,XY normogonadic control subjects. Age and b...

Background: Stimulatory therapy with gonadotrpins is an effective treatment to induce spermatogenesis in men with idiopathic hypogonadotroptic hypogonadism (IHH). The aim of this study was to assess the effectiveness of human chorionic gonadotropin / human menopausal gonadotropin on hypogonadotropic infertile men. Materials and Methods: This study included fifty-six azoospermic infertile men wi...

Idiopathic hypogonadotropic hypogonadism (IHH) is a rare condition in which puberty does not take place naturally. We aimed to develop and follow an internet-based cohort and to improve our understanding of the disease. We established an internet-based questionnaire survey. A total of 74 male IHH patients were recruited from the Chinese largest IHH network social group. The clinical symptoms be...

Idiopathic hypogonadotropic hypogonadism (IHH) is a condition characterized by failure to undergo puberty in the setting of low sex steroids and low gonadotropins. IHH is due to abnormal secretion or action of the master reproductive hormone gonadotropin-releasing hormone (GnRH). Several genes have been found to be mutated in patients with IHH, yet to date no mutations have been identified in t...

OBJECTIVE What initiates the pubertal process in humans and other mammals is still unknown. We hypothesized that gene(s) taking roles in triggering human puberty may be identified by studying a cohort of idiopathic hypogonadotropic hypogonadism (IHH). METHODS A cohort of IHH cases was studied based on autozygosity mapping coupled with whole exome sequencing. RESULTS Our studies revealed thr...
