Impaired testicular function, i.e., hypogonadism, can result from a primary testicular disorder (hypergonadotropic) or occur secondary to hypothalamic-pituitary dysfunction (hypogonadotropic).Hypogonadotropic hypogonadism ...

The diagnostic suspicion of congenital central hypogonadism is based on clinical signs. Biochemical confirmation is challenging, especially after the postnatal activation stage of the hypothalamic–pituitary–testicular axis. ...

In the prepubertal male, Sertoli cells are the most active testicular cell population. Without stimulation tests, prepubertal hypogonadism can only be evidenced if Sertoli cell function is assessed. Anti-müllerian hormone ...

Disorders of sex development (DSD) and hypogonadism are genetically heterogeneous and include a broad spectrum of phenotypes. Recent advances in biology and medicine have introduced impressive improvements in both clinical ...

Aim: Hormone replacement therapy with testosterone for pubertal induction in boys with congenital hypogonadotropic hypogonadism (CHH) achieves virilization but not spermatogenesis. By contrast, human chorionic gonadotropin ...

Context: The efficacy and safety of testosterone replacement therapy (TRT) in hypogonadal men remain incompletely understood. Objective: To conduct a systematic review and meta-analysis of randomized clinical trials (RCT) ...

Obese men may present hypogonadothrofic hypogonadism, mainly related to higher insulinemia and aromatase activity. Our objectives were to evaluate the relationship of sex-hormones profiles and frequency of depressive ...

Summary Objetive The purpose of this study was to demonstrate that Sal-T is a reliable biomarker of androgen status in the diagnosis of male hypogonadism. Design In order to validate the salivary testosterone assay (Sal-T), ...
