The term “estrogen dominance” was coined by Dr. John R. Lee, MD.1 Estrogen dominance is a common underlying cause of many symptoms associated with the menstrual cycle, and there are two types of estrogen dominance – relative and frank. Relative estrogen dominance is present when the estradiol level is normal or low, but there is insufficient progesterone to balance the estradiol. Frank estrogen dominance is present when the estradiol level is elevated.2
It is important to note that many women are not estrogen dominant due to excessive estrogen. Rather, they are in a state of relative estrogen dominance due to an insufficient progesterone level. The treatment protocols for estrogen excess and inadequate progesterone are different; therefore, it is best to monitor salivary hormone levels regularly to prescribe an individualized and effective treatment protocol for each patient. Always consider potential treatment protocols within the context of your patient’s overall clinical presentation and other factors, including family history.
Symptoms and conditions associated with estrogen dominance may include:
- Fibrocystic breasts1

To screen for the presence of estrogen dominance in patients who have a menstrual cycle, consider ordering the Expanded Cycling Female Hormone Panel (eFHP). A Sample eFHP Report is available in your Provider Portal HERE.
To place a test order, click here. You will find the Expanded Cycling Female Hormone Panel listed under the section header Reproductive Hormone Panels & Tests.
As a reminder, DiagnosTechs will drop ship test kits directly to your patients. You may select this option at the top of the order form.
