Abstract
Patients with congenital hypogonadism will encounter many health care professionals during their lives managing their health needs; from antenatal and infantile periods, through childhood and adolescence, into adult life and then old age. The pubertal transition from childhood to adult life raises particular challenges for diagnosis, therapy and psychological support, and patients encounter many pitfalls. Many patients with congenital hypogonadism and delayed or absent puberty are only diagnosed and treated after long diagnostic journeys, and their management across different centres and countries is not well standardised. Here we reconsider the management of pubertal delay, whilst addressing problematic diagnostic issues and highlighting the limitations of historic pubertal induction protocols - from the perspective of both an adult and a paediatric endocrinologist, dealing in our everyday work with the long-term adverse consequences to our hypogonadal patients of an incorrect and/or late diagnosis and treatment in childhood.
