Gynecomastia in prepubertal and pubertal men.

Area of Science:

• Endocrinology
• Pediatric Endocrinology
• Men's Health

Background:

• Gynecomastia, or male breast enlargement, can be benign but may indicate underlying endocrine disorders.
• It often causes significant psychological distress, necessitating a clear understanding of its causes.
• Distinguishing physiological gynecomastia from pathological causes is crucial for appropriate patient management.

Purpose of the Study:

• To review the pathogenesis of gynecomastia.
• To differentiate normal developmental variants from pathological causes.
• To inform clinical evaluation and management strategies.

Main Methods:

• Literature review of case reports and existing studies on gynecomastia.
• Analysis of potential etiological factors and pathogenetic mechanisms.
• Evaluation of current treatment approaches and evidence.

Main Results:

• The exact pathogenesis of gynecomastia remains unclear, with a suspected local imbalance between estrogen and androgen activity.
• Gynecomastia in prepubertal boys warrants immediate endocrine evaluation, while pubertal gynecomastia is typically physiological.
• Antiestrogen therapy may help persistent pubertal gynecomastia, but aromatase inhibitors show no advantage over placebo.

Conclusions:

• Treatment for gynecomastia should be tailored to the underlying cause.
• Current evidence is insufficient to recommend medical therapy for idiopathic gynecomastia in children.
