BHRT stands for Bioidentical hormone replacement therapy. It is also known as bioidentical hormone therapy or natural hormone therapy. BHRT uses bioidentical hormones derived from plant extracts chemically modified to be structurally indistinguishable from human endogenous hormones.
According to JoAnn Manson, chief of preventive medicine at Brigham and Women’s Hospital in Boston and the Elizabeth F. Brigham Professor of Women’s Health at Harvard Medical School, “Bioidentical hormone preparations are medications that contain hormones that are an exact chemical match to those made naturally by humans.”
Some bioidentical hormones are made by drug companies, are approved by the FDA, and are sold in standard doses. Other bioidentical hormone preparations are made at special pharmacies called compounding pharmacies, which make the preparations on a case-by-case basis for each patient. Those “custom-made” preparations are not approved by the FDA.
