Hormone Therapy - HRT, HT, ET, EPT, What Does it All Mean?

To help sort out the confusion about the multiple hormone therapy abbreviations, Dr. Carolyn Crandall has provided us this explanation of HRT, HT, ET (Estrogen Therapy) and ERT (Estrogen Replacement Therapy).

Menopausal Hormone Therapy (HT)

HRT stands for "hormone replacement therapy." In the medical field, HRT, or hormone replacement therapy is an older term, and has recently been replaced with "menopausal hormone therapy (HT).

Menopausal hormone therapy," abbreviated HT, is a general term for any type of hormone that a woman takes -- which could mean almost anything -- any combination of estrogen with progestin, estrogen alone, or progestin alone. If you want to describe a more specific type of hormone therapy, you can use the terms estrogen therapy (ET) or estrogen progestin therapy (EPT) as described below.

Estrogen Therapy (ET)

ERT stands for "estrogen replacement therapy." Again, because of the recent shift in medical terminology, ERT has been replaced by a newer term. Now, estrogen therapy, abbreviated ET, is the term we use to refer to estrogen as a therapy, WITHOUT progesterone. This new term, estrogen therapy, has been chosen in part because we are not really REPLACING estrogen when we prescribe estrogen therapy. After menopause, women are not really "naturally" meant to produce estrogen any more. Therefore, ET is a more precise (or possibly less offensive) way to describe the medication.
