Dr. John R. Woodward, Hormone Specialist in Dallas, Texas

Welcome to our medical practice website, which helps women and men better understand hormones, menopause, andropause and bio-identical hormone replacement therapy including estrogen, biest, pregnenolone, testosterone, progesterone, DHEA and DHEA Sulfate, thyroid hormones and occasionally human growth hormones (HGH) if indicated.

Bio-identical Hormone Replacement Therapy (BHRT) has been a big part of my gynecology practice for the last 30 years. In talking with my patients, it became evident that women and men were not getting satisfactory medical treatment for menopause and andropause symptoms. Although I began to focus more on BHRT, I continue to diagnose, treat, advise, and research other conditions related to gynecology and endocrinology – such as thyroid disorders, cancer screening, cholesterol, weight/diet concerns, Alzheimer’s, aging, vitamin/herbal supplements, and good health/healthy living – for all my patients. To learn more, browse the categories below, or contact me to make an appointment.

Bio-identical Hormone Doctors and Information

Confusion exists regarding the use of the term “natural” versus “bio-identical” hormones, particularly as it applies to the hormones estradiol and progesterone which must be molecule for molecule absolutely “identical” to hormones produced by the human body to have the desired effects.  (more…)


DHEA is a naturally produced pro-hormone. DHEA occurs in the body as a result of a cascading molecular synthesis from the very large complex molecule to progressively smaller more specialized ones. Acetate in the body is converted into cholesterol when certain carbon chains are removed to yield pregnenolone, known as the “grandmother” of all hormones.” (more…)


The best two screening blood tests for thyroid function are a free T3 (triiodothyronine) and free T4 (free thyroxin) both done by all labs. Another thyroid test, the TSH, should be done as follow up if the free T3 and free T4 are abnormal. (more…)


DefinitionMenopause is the permanent end of menstruation and fertility, defined as occurring 12 months after the last menstrual period. Menopause is a natural biological process, not a medical illness. Even so, the physical and emotional symptoms of menopause can disrupt your sleep, sap your energy and – at least indirectly -trigger feelings of sadness and loss. (more…)


There is evidence at present that the condition of being overweight is different from the condition of being obese. Being overweight is the result of taking in more calories than one expends. Obesity, on the other hand, is much more complex. (more…)

Subcutaneous Hormone Pellets

Bioidentical, natural hormone replacement therapy can be delivered using tiny pellets inserted under the skin. Hormones are secreted in minute amounts into the blood stream daily. (more…)
