Introduction: Delayed puberty (DP), affecting over 2% of adolescents, is defined as pubertal onset at 2-2.5 SDs later than the general population. Two common underlying aetiologies are self-limited DP (SLDP) and congenital hypogonadotrophic hypogonadism (HH). However, these can be difficult to discern between on first presentation of a patient to endocrinology services. This study sought to elucidate phenotypic and genotypic differences between the two diagnoses in order to op...

Delayed puberty (DP) is defined as pubertal onset 2-2.5 SDs later than the general population. The most common aetiology is self-limited DP (SLDP). However, during adolescence, it is a clinical challenge to differentiate SLDP from the more severe disease congenital hypogonadotrophic hypogonadism (HH). This study sought to elucidate phenotypic and genotypic discrepancies between the two diagnoses to improve diagnosis and management. This was a retrospective study of a UK DP coh...

Background and aims: Hypogonadotropic hypogonadism is characterised by inadequate secretion of gonadotropins (luteinising hormone (LH) and follicle-stimulating hormone (FSH)) leading to absent, partial or arrested puberty. In males, classical treatment with testosterone promotes virilisation but does not facilitate testicular growth or spermatogenesis. Conversely, treatment with gonadotropins or gonadotropin-releasing hormone (GnRH) stimulates Sertoli and Leydig cells directly...

Congenital hypogonadotropic hypogonadism (CHH) is a pathological condition characterised by lack of pubertal onset and must be differentiated from self-limited delayed puberty (SLDP). There is a significant overlap between these two conditions both in clinical and biochemical features, with current diagnostic approaches lacking sensitivity. Thus, paediatric endocrine clinicians are faced with difficulty in ascertaining the correct diagnosis in adolescence. The presence of cert...
