Transition of Care from Childhood to Adulthood: Congenital Hypogonadotropic Hypogonadism

Passage from childhood to adult life involves biological changes culminating in full reproductive capacity as well as psychosocial development. For patients with congenital hypogonadotropic hypogonadism (CHH), this can be an emotionally challenging time as their pubertal failure results in striking physical differences from their peers. CHH is difficult to differentiate from common disorders of puberty such as constitutional delay of growth and puberty. As such, delays in diagnosis are frequent, and it is a common source of stress and frustration for these adolescents. While effective treatments are available for inducing puberty and attaining fertility is possible in most cases, patients may find it difficult to cope with living with CHH. A critical issue for adolescents with CHH is the risk for being lost to follow-up during the transition from pediatric-centered care to adult care. This article will review the state of the art in diagnosis and treatment of patients with CHH with a particular focus on supporting an effective transition from pediatric-centered care to adult-oriented endocrine services. A synthesis of best practices is offered to help guide clinicians in supporting patients and families during this challenging period of care.
