Do anti estrogen pills remove gynecomastia in teenage boys? is that a good therapy?

Gynecomastia: Generally, no treatment is required . Pubertal gynecomastia resolves spontaneously within several weeks to 3 years in approximately 90% of patients. Breasts greater than 4 cm in diameter may not completely regress. For patients with idiopathic gynecomastia or with residual gynecomastia after treatment of the primary cause, medical (antiestrogens ) or surgical treatment may be considered.

Not Necessary.: For most young men with gynecomastia, medical treatment is not necessary. This persistent, gynecomastia is best treated with surgical excisional procedures. This may include direct excision of breast gland tissue, liposuction surgery, and in some cases ( especially after significant weight gain/loss) skin excision also.
