Background: Anogenital distance (AGD) is an indicator of androgen action in utero. Reduced AGD has been found in males with hypospadias, cryptorchidism, low semen quality and infertility. Its usefulness as a clinical marker in patients with Disorders of Sex Development (DSD) is currently being investigated. However, detailed age, sex and method related reference ranges do not exist. Whether individual (body-size-adjusted) AGD is stable postnatally also remains to be e...

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of growth retardation. Diagnostic criteria include age- and sex-dependent low basal IGF1 levels (<2.5th percentile), height ≤ −3SDS, absence of growth hormone (GH) deficiency and of any secondary causes of growth failure.Objectives: Phenotypic description, follow-up and molecular studies in a cohort of patients diagnosed with growth f...

Background: A combination of GH and a gonadotropin releasing hormone analogue (GnRH a) is hypothesized to improve adult height in children with a poor adult height prediction.Study design: In this multicenter study, 24 girls in early puberty (bone age ≤12.0 y),with a predicted adult height ≤151.0 cm and normal body proportions were treated with GH (Zomacton) 50 μg/kg per day and triptorelin (Gonapeptyl) 3.75 mg/month SC or IM (for 4 year...

Objective: IGF-1 receptor mutations (IGF1RM) are a rare abnormality; however, affected patients exhibit severe postnatal growth retardations without catch-up growth. Although several cases of IGF1RM have been described, a comprehensive retrospective analysis of the potential benefit of rhGH treatment is still missing. The aim of this study was therefore to investigate baseline auxology, response to rhGH therapy and potential metabolic effects in patients with IGF1RM in compari...

Background: SHOX and enhancer regions on PAR1 disorders have variable phenotypic consequences such as idiopathic short stature (ISS) and Leri-Weill Dyschondrosteosis (LWD).Objective and hypotheses: The aim of this observational multicentric study was to describe phenotypes and genotypes of a large population with mutation on SHOX and adjacent regions and to identify a possible phenotype–genotype correlation.M...

Background: A combination of GH and a GnRH agonist is sometimes used to improve adult height in children with a poor height prediction, only few studies support this.Study design: In this multicenter study, 24 short girls in early puberty, with a bone age below 12.0 years, an adult height prediction below 151.0 cm and normal body proportions were treated with GH (Zomacton) transjections 50 μg/kg per day and triptorelin (Decapeptyl) i.m. (3.75 mg/mon...

Background: Congenital diabetes insipidus (DI) can be due to mutations in the arginine vasopressin (AVP) gene (familial neurohypophyseal DI), the AVP receptor type 2 (AVPR2) or aquaporin 2 (AQP2) genes (congenital nephrogenic DI, NDI). The clinical manifestation of congenital NDI, especially the response to AVP, can vary greatly depending on the functional effect of the AVPR2 mutation. Here we present two male siblings with NDI and partial response to ddAVP.<p class="abste...

Background: Disproportional short stature (DSS) is the most frequent clinical presentation of skeletal dysplasias, which are a heterogeneous group of more than 450 disorders of bone. Skeletal survey is important to establish the diagnosis and to guide the genetic test, but has several limitations, especially in mild and atypical cases.Objective and hypotheses: To identify the genetic aetiology of DSS by exome sequencing.Method: Who...

Introduction: Hypogonadotropic hypogonadism (HH) is a rare condition, where a definitive diagnosis is often hard to reach.Objectives: To describe the clinical, biochemical and genetic findings in cases with suspected HH in the West of Scotland who were referred for genetic analysis between 2016 and 2020.Methods: Information was collected on clinical assessment including family hist...

Context: Alterations in semen characteristics and Sertoli and Leydig cell function have been described in obese male adults. Whether these alterations occur before adulthood has not been fully evaluated.Objective and Design: Cross sectional study from 2010 to 2018 describing gonadic function in overweight-obese (ow/ob) boys through childhood and adolescence.Setting: Monocentric study in the Pediatric Endocrinology ...
