Will anti estrogen pills remove gynecomastia in teenage boys?

Gynecomastia: Yes. With the administration of clomiphene, an antiestrogen, approximately 50% of patients achieve partial reduction in breast size, and approximately 20% of patients note complete resolution. Tamoxifen, an estrogen antagonist, is effective for recent-onset and tender gynecomastia. Up to 80% of patients report partial to complete resolution. Another drug is danazol.

Probably not: Although anti-estrogen pills have been used to prevent or minimize the effects of estrogen like side effects of other medications, I do not believe they will work to remove or improve existing and established gynecomastia.

Consider : Consider seeing a plastic surgeon to discuss options.
