Study Title:

Gynecomastia: Etiology, Diagnosis, and Treatment.

Study Abstract

Gynecomastia is a relatively common disorder. Its causes range from benign physiological processes to rare neoplasms. In order to properly diagnose the etiology of the gynecomastia, the clinician must understand the hormonal factors involved in breast development. Parallel to female breast development, estrogen, GH, and IGF-1 are required for breast growth in males. Since a balance exists between estrogen and androgens in males, any disease state or medication that can increase circulating estrogen or decrease circulating androgen, causing an elevation in the estrogen to androgen ratio, can induce gynecomastia. Due to the diversity of possible etiologies, including a neoplasm, performing a careful history and physical is imperative. Once gynecomastia has been diagnosed, treatment of the underlying cause is warranted. If no underlying cause is discovered, then close observation is appropriate. If the gynecomastia is severe and of recent onset, however, medical therapy can be attempted and if ineffective, glandular tissue can be removed surgically.
