The activation of the hypothalamic-pituitary-gonadal (HPG) axis during the first six months of life in boys marks the period of “mini-puberty”. It is characterized by a surge of gonadotropins, testosterone, and an increase of Sertoli cells and germ cells, crucial for future reproductive capacity. Boys with severe congenital hypogonadotropic hypogonadism (CHH) often present with undescended testes and micropenis and lack mini-puberty, leading to impaired responses t...

Introduction: Gliomas are the most common solid tumours during childhood. In children with neurofibromatosis Type 1 (NF1) and optic pathway glioma (OPG), growth hormone excess has been described. However, this phenomenon has not been reported in children with OPG without NF1. We aimed to describe the growth and IGFs/IGFBP3 levels in a large cohort of paediatric patients with non-NF1- associated central nervous system (CNS) tumours.Method...

Introduction: Comprehensive evaluation of the gonadotropic axis, including pituitary and gonadal assessment, using a diagnostic test with aGnRH (Triptorelin) could be useful in the differential diagnosis between hypogonadotropic hypogonadism (HH) and self-limited delayed puberty (SLDP) or amenorrhea of unknown cause.Objective: To assess the performance of the Triptorelin test for the diagnosis of HH and to compare it wit...

Background: Hypogonadotropic hypogonadism, a condition of central hypogonadism secondary to deficiency of gonadotropin releasing hormone and/or gonadotropins, is a rare disease affecting approximately 1 in 5000-15,000. A key step in improving understanding of best practice in this condition is the collection of geographically widespread data. Standardised and accessible international data collection can facilitate this, with implementation of established proto...
