Personalized Bioidentical Hormone Care for Women & Men
Bioidentical hormones have the same molecular structure as hormones produced by the human body. David Nazarian, M.D., Board-Certified in Internal Medicine, provides comprehensive evaluation for women and men considering bioidentical hormone therapy, including FDA-approved options, compounded preparations when clinically appropriate, individualized risk assessment, and ongoing monitoring.
What Does “Bioidentical” Mean?
A bioidentical hormone is chemically identical to a hormone naturally produced by the body. Examples include estradiol, micronized progesterone, and testosterone. Importantly, “bioidentical” does not mean the same thing as “compounded.” Some bioidentical hormone products are FDA-approved and manufactured in standardized doses; others are custom compounded for an individual patient.
FDA-Approved vs. Compounded Bioidentical Hormones
FDA-Approved Bioidentical Hormones
FDA-approved products are available for several clinical uses and include formulations containing estradiol and micronized progesterone. Approved testosterone products are available for appropriate indications in men. These medications have standardized manufacturing, labeling, and regulatory review.
Compounded Hormone Preparations
Compounding may be considered when a patient has a clinical need for a formulation, dose, combination, or ingredient profile that an available FDA-approved product cannot meet. Compounded medications are not FDA-approved as finished products and should not automatically be assumed to be safer or more effective.
Who May Benefit From a Hormone Evaluation?
Symptoms can suggest a hormonal problem, but symptoms alone do not prove a hormone deficiency. A medical evaluation can help distinguish hormonal changes from thyroid disease, sleep disorders, medication effects, metabolic conditions, nutritional deficiencies, mood disorders, and other causes.
Bioidentical Hormone Therapy for Women
For women in perimenopause or menopause, hormone therapy may be considered for bothersome vasomotor symptoms such as hot flashes and night sweats and for selected genitourinary symptoms. Treatment decisions consider age, time since menopause, whether the uterus is present, symptom severity, personal and family history, cardiovascular and thrombotic risk, breast and endometrial considerations, and patient preferences.
Options may include estradiol therapy, micronized progesterone, and local vaginal therapy when appropriate. Women with an intact uterus who use systemic estrogen generally require appropriate endometrial protection unless there is a clinical reason otherwise.
Bioidentical Hormone Therapy for Men
For men, testosterone treatment should begin with an accurate diagnosis—not simply fatigue, reduced libido, age, or one laboratory result. Evaluation generally requires compatible symptoms together with consistently low, appropriately obtained testosterone measurements and assessment for possible underlying causes.
Fertility goals, sleep apnea, blood counts, prostate considerations, cardiovascular risk, medications, and other relevant factors should be reviewed before therapy. Learn more about low testosterone evaluation and testosterone replacement therapy in Los Angeles.
How Bioidentical Hormones Can Be Given
The best route depends on the hormone, indication, medical history, preferences, evidence, and treatment goals. Options can include:
Patches, gels, or creams when clinically appropriate.
Including oral micronized progesterone and selected estrogen formulations.
For selected genitourinary symptoms of menopause.
Gels or injections for appropriately diagnosed men, depending on clinical circumstances.
Pellets and compounded preparations require a separate discussion of evidence, dosing, reversibility, quality control, and potential risks. No delivery method is automatically best for every patient.
Our Evaluation & Treatment Process
Symptoms, medical history, medications, family history, reproductive and fertility goals, prior hormone use, sleep, lifestyle, and treatment goals.
Laboratory testing and other evaluation are selected according to the clinical question rather than using the same panel for every patient.
Benefits, risks, alternatives, FDA-approved options, and compounded therapy when clinically appropriate are discussed.
Response, side effects, relevant laboratory findings, screening needs, and the continued indication for therapy are reassessed over time.
Benefits, Side Effects & Safety
The potential benefit depends on why therapy is being used. For appropriately selected menopausal patients, hormone therapy can be effective for vasomotor symptoms and certain genitourinary symptoms. Testosterone therapy can benefit appropriately diagnosed men with hypogonadism. Hormone therapy is not a universal treatment for fatigue, weight gain, aging, or general wellness.
Potential adverse effects and risks vary by hormone, dose, route, duration, and patient. Depending on the therapy, considerations may include abnormal bleeding, breast symptoms, acne or androgenic effects, changes in blood counts, blood clots, cardiovascular events, gallbladder disease, endometrial risk, fertility effects, and other hormone-specific concerns. Individual risk assessment is essential.
How Long Does It Take to Feel a Difference?
There is no single timeline that applies to every patient or symptom. Some symptoms may improve over weeks, while others may take longer. Treatment should be reassessed rather than automatically escalated when symptoms persist, because persistent symptoms may have a nonhormonal cause. The goal is clinically meaningful improvement with an acceptable safety profile—not simply reaching a predetermined laboratory number.

Frequently Asked Questions About Bioidentical Hormone Therapy
Are bioidentical hormones the same as HRT?
Bioidentical hormones are one category of hormones that may be used as part of hormone replacement therapy. The term describes molecular structure, not a separate guarantee of safety or effectiveness.
Are bioidentical hormones safer than traditional hormone therapy?
Not simply because they are called bioidentical. Risk depends on the specific medication, dose, route, indication, patient characteristics, and monitoring. FDA-approved bioidentical options exist.
Are all bioidentical hormones compounded?
No. FDA-approved products containing estradiol and micronized progesterone are examples of bioidentical hormones. Compounded preparations are a separate category.
Do I need hormone testing before treatment?
Testing depends on the clinical situation. Menopause is often diagnosed clinically, whereas suspected testosterone deficiency in men generally requires appropriately obtained laboratory confirmation. Other testing is selected when it can clarify diagnosis or change management.
Can bioidentical hormones help with weight loss?
Hormone therapy is not a weight-loss treatment. Hormonal changes can affect body composition and symptoms that influence activity or sleep, but unexplained weight change deserves a broader medical evaluation.
Can bioidentical hormones help libido?
Low libido has many possible hormonal and nonhormonal causes. Treatment depends on the diagnosis, sex, menopausal status, medications, relationship factors, mental health, sleep, and other contributors rather than automatically prescribing hormones.
Are hormone pellets the same as bioidentical hormone therapy?
Pellets are a delivery method, not a definition of bioidentical therapy. Patients considering pellets should discuss dosing, reversibility, evidence, side effects, and alternative routes.
How long can I stay on bioidentical hormones?
There is no universal maximum duration. Continued therapy should be periodically reassessed based on the indication, response, changing health risks, patient preferences, and whether benefits continue to outweigh potential harms.
What is the difference between bioidentical and synthetic hormones?
“Bioidentical” means the molecule is structurally identical to a hormone made by the human body. Other hormone medications may have different structures. Clinical decisions should focus on evidence, indication, dose, route, quality, and safety rather than assuming one category is universally superior.
How do I choose a bioidentical hormone doctor near me?
Look for a licensed clinician who performs an appropriate medical evaluation, discusses FDA-approved and compounded options accurately, reviews contraindications and alternatives, uses evidence-informed monitoring, and does not promise that hormone therapy will treat every symptom of aging.
