Gynecomastia and hormones.

Area of Science:

• Endocrinology
• Men's Health
• Clinical Medicine

Background:

• Gynecomastia, defined as the enlargement of male breast tissue, is a prevalent condition observed across various age groups, including neonates, adolescents, and the elderly.
• Physiological gynecomastia accounts for approximately 25% of cases and is typically benign and self-resolving.
• However, proliferation of male breast tissue can also be induced by various medical conditions and pharmaceutical agents.

Purpose of the Study:

• To review the common causes and diagnostic considerations for gynecomastia.
• To emphasize the importance of biochemical evaluation when physiological or iatrogenic causes are excluded.
• To highlight non-endocrine conditions that may present with gynecomastia.

Main Methods:

• Review of existing literature on gynecomastia.
• Discussion of etiological factors, including hormonal imbalances (estrogen excess, androgen deficiency).
• Consideration of differential diagnoses, encompassing endocrine disorders and non-endocrine illnesses like liver and kidney disease.

Main Results:

• True gynecomastia is frequently associated with endocrine disorders leading to estrogen excess or androgen deficiency.
• Non-endocrine conditions such as liver failure and chronic kidney disease are significant potential causes.
• Resolution of gynecomastia can often be achieved by addressing the underlying cause or discontinuing causative medications.

Conclusions:

• Gynecomastia necessitates a thorough evaluation to rule out physiological and iatrogenic causes before investigating underlying pathologies.
• Endocrine and non-endocrine conditions represent key differential diagnoses for persistent gynecomastia.
• While medical management focuses on the underlying etiology, the psychosocial impact of gynecomastia warrants careful consideration.
