Newswise — While there continues to be confusion about the benefits and risks of hormone therapy, The Endocrine Society is concerned about the continued propagation of misleading information about bioidentical hormones. Many well known figures use the term to describe non-standardized hormone therapies that are formulated by compounding pharmacies. The formulations are often based on poor and inaccurate tests for an individual's own hormone levels.

A bioidentical hormone is in fact one that is identical in structure to that which is produced in the human body. Considering this factual definition, patients can obtain bioidentical hormones as FDA-approved preparations formulated with strict oversight and dispensed by retail pharmacies.

Studies have shown both benefits and risks of hormone therapy. Risk accompanies therapy regardless of the chemical structure of the hormone. However, medications from compounding pharmacies—including bioidentical hormones—are not subject to FDA monitoring for dose, purity, safety or efficacy. Inconsistency of dose and purity presents additional risk to patients.

In 2006, The Endocrine Society issued a position statement, which has become policy of the American Medical Association (AMA) with widespread support of the medical community, calling for increased regulatory oversight of all bioidentical hormones (
