constitutional delay of growth and puberty

Constitutional delay of growth and puberty is a transient endocrine condition characterized by a slower progression through the stages of growth and an attenuated pubertal growth spurt. This condition arises from a temporary state of hypogonadotropic hypogonadism, where lower levels of hormones responsible for pubertal development result in delayed skeletal maturation. It is typically recognized during adolescence when growth and pubertal milestones are not achieved as expected compared to peers. Although the precise cause remains unclear, most individuals eventually catch up in their development over time.

Individuals with constitutional delay of growth and puberty often present with a prolonged period of childhood, delayed skeletal maturation, and a slower-than-expected pubertal growth spurt. They may also exhibit relatively low levels of insulin-like growth factor-1, contributing to their delayed growth. Not all individuals experience all these features, and severity varies considerably. The condition is usually identified when routine evaluations reveal that the expected pubertal changes and growth patterns are not occurring at the typical age.

The precise genetic basis of constitutional delay of growth and puberty is not fully understood and is thought to result from a complex interplay of genetic and environmental factors. In this condition, a transient state of hypogonadotropic hypogonadism leads to reduced stimulation of the hormones necessary for pubertal development. Because no specific genes have been consistently linked to this condition, its underlying causes remain an active area of investigation.

Currently, management focuses on supportive care and symptom management. Treatment is tailored to the individual and typically involves a multidisciplinary team that may include an endocrinologist and primary care providers. While there are no treatments specifically approved for this condition, some individuals may benefit from temporary hormonal therapy to help stimulate pubertal development when indicated by clinical judgment. Patients should discuss treatment options with their healthcare team to determine which therapies may be appropriate for their specific situation.

Outcomes for individuals with constitutional delay of growth and puberty are generally favorable, although the course can vary widely between individuals. Most individuals experience a delayed onset of puberty, but with supportive care and time, many eventually undergo normal pubertal development. Outcomes described in medical literature continue to evolve as standards of care improve. Families often find it helpful to connect with an endocrinologist or genetic counselor to discuss concerns and monitor developmental progress.

Clinical trials are underway exploring new treatment approaches for constitutional delay of growth and puberty. Individuals interested in clinical trials can search ClinicalTrials.gov or consult their care team about eligibility.
