Background: Due to delays in diagnosis of Idiopathic Short Stature (ISS), puberty has often started when Growth Hormone (GH) is initiated.Objective and hypotheses: To compare GH+leuprorelin (GH+L) with GH alone in patients with ISS and at Tanner puberty stage 2 or 3. We hypothesised that co-administration of GH+L for 2–3 years would delay puberty, prolong GH efficacy and increase adult height.Method: A phase 3, randomised, ope...

Background: Pubertal gynecomastia is a common condition appearing in up to 65% of adolescent boys. However, if male breast development is over B3–B4 and lasts more than 2–3 years, persistent pubertal gynecomastia (PPG) may be the sign of serious endocrine disease and the source of considerable psychological discomfort.Objective and hypotheses: We investigated a cohort of 24 adolescents with PPG followed at the Pediatric Endocrinogy Unit over a ...

Background: Epidemiological evidence in Europe indicates the increasing prevalence of premature puberty, especially in girls. This may be attributed to in utero and early-life exposure to environmental estrogen-like compounds present in pesticides, plastics (bisphenol A, phtalates …) and beauty products.Objective and hypotheses: The aim of this study was to assess the prevalence of premature thelarche (PT) and central precocious puberty (C...

Background: Pubertal virilization in a 46,XY DSD patient is generally due to partial androgen insensitivity, 5-alpha-reductase deficiency, or 17-ketoreductase deficiency. Recently, reports have identified virilization signs associated with NR5A1/SF-1 gene mutations.Cases presentation and method: We present two unrelated cases of pubertal virilization due to NR5A1/SF-1 gene mutation. Both were suspected to be primarily affected by 5-alph...

Background: Partial androgen insensitivity syndrome (PAIS) covers a large spectrum of phenotypes, with the common denominator being insufficient virilisation of the external genitalia in an XY child with normal testosterone (T) production. Genetic diagnosis of PAIS is based on the identification of an androgen receptor (AR) gene mutation.Aim: The aim of this work was to determine whether the PAIS-like phenotype is associated with other gene mutations.</p...

Background: A recent report (JCI, 2014) described a new homozygous NR5A1/SF-1 mutation in a patient with XY DSD and spleen agenesis. To date, no other data have confirmed this association, raising the hypothesis of fortuity.Case presentation and method: We had the opportunity to study an adolescent girl referred for virilisation during puberty. She presented voice deepening and clitoral hypertrophy. Biological investigations showed high plasma testostero...

Background: The clinical diagnosis of partial androgen insensitivity syndrome (PAIS) should be systematically considered for all 46,XY newborns/infants with undervirilisation contrasting with normal/elevated plasma testosterone levels. Confirmation of PAIS is based on the identification of an androgen receptor (AR) gene mutation.Aim: This work was undertaken to determine whether the minor forms of undervirilisation such as isolated hypospadias, isolated ...

Background: Pubertal gynecomastia is observed in up to 65% of adolescent males. It is usually idiopathic and tends to regress within 1–2 years, although sometimes pubertal gynecomastia persists.Case presentation and methods: We investigated three adolescent males with isolated persistent pubertal gynecomastia: twin brothers and an unrelated adolescent boy. The twins (17 years) had normal male external genitalia. Biological testing showed normal test...

Introduction: According to EAU's guidelines, hypospadias (HS) repair is best performed between 6 and 18 months of age. Little is known about the long-term patient satisfaction or urological outcome following HS surgery.Aims: To examine the psychosexual and urological outcome of young adult men (16-21 years old) born with all forms of non-syndromic HS as compared to healthy controls, as well as patient and parental sa...

Introduction: Limited, small-scale studies have revealed that men with proximal hypospadias (HS) or with other signs of undermasculinisation (i.e. complex HS) are at risk of reduced fertility and/or impaired testicular hormone synthesis. However, the extent of this phenomenon and if milder forms of isolated HS are also affected, remains unclear.Aims: To explore reproductive hormones and semen quality of young men (16-21 ...
