Delayed puberty, often seen in boys, can be constitutional or due to gonadotropin deficiency. Triptorelin stimulation may help distinguish these conditions, aiding diagnosis.

Area of Science:

Pediatric Endocrinology
Reproductive Medicine
Adolescent Health

Background:

Delayed puberty is defined as the absence of pubertal signs by age 13 in girls and 14 in boys.
Causes include functional impairment, hypopituitarism, or primary gonadal failure.
Constitutional delay of puberty is the most common cause, particularly in males.

Purpose of the Study:

To discuss the etiology, diagnostic approaches, and therapeutic strategies for delayed puberty.
To evaluate the utility of triptorelin stimulation as a screening test for differentiating constitutional delay from gonadotropin deficiency in boys.

Main Methods:

Review of literature on the causes and diagnosis of delayed puberty.
Analysis of endocrine testing, specifically triptorelin stimulation, in differentiating conditions.

Focus on distinguishing constitutional delay from gonadotropin deficiency in adolescent males.

Main Results:

Distinguishing constitutional delay from gonadotropin deficiency can be challenging in adolescents.
Triptorelin stimulation test shows an increase in Luteinizing Hormone (LH) in individuals with constitutional delayed puberty and bone age >11.5 years.
This increase in LH differentiates them from patients with true gonadotropin deficiency.

Conclusions:

Constitutional delay of puberty is common, especially in boys, and often benign.
Triptorelin stimulation test appears to be a valuable screening tool to exclude gonadotropin deficiency in boys with delayed puberty.
Accurate diagnosis is crucial for appropriate management and therapeutic intervention.
