Men’s Hormone Optimization & Testosterone Replacement Therapy in Los Angeles & Beverly Hills
Men’s hormone optimization begins with determining whether symptoms are actually caused by low testosterone or another medical issue. At My Concierge MD, David Nazarian, MD, a board-certified internal medicine physician, evaluates men with fatigue, low libido, reduced strength, mood changes, brain fog, sleep problems, and changes in body composition using medical history, examination, and appropriate laboratory testing before recommending treatment.
For men with confirmed testosterone deficiency and an appropriate clinical indication, testosterone replacement therapy (TRT) may be considered. For others, the better approach may involve addressing sleep apnea, obesity, diabetes risk, thyroid disease, medications, nutrition, stress, fertility goals, or other contributors that can affect symptoms and testosterone levels.
What Is Men’s Hormone Optimization?
Men’s hormone optimization is a broader clinical approach than simply prescribing testosterone. It includes evaluating symptoms, confirming hormone levels correctly, identifying reversible causes, reviewing fertility goals, and addressing lifestyle and metabolic factors that may influence testosterone and overall health.
Symptoms That May Be Associated With Low Testosterone
- Reduced libido or sexual interest
- Fatigue or reduced energy
- Loss of muscle mass or strength
- Increased body fat
- Mood changes or irritability
- Reduced motivation or concentration
- Erectile symptoms
- Reduced exercise recovery
- Changes in sleep or overall well-being
These symptoms are not specific to low testosterone. Sleep disorders, depression, thyroid disease, diabetes, medication effects, chronic illness, and other conditions can produce similar complaints, so diagnosis should not be based on symptoms alone.


How Low Testosterone Is Evaluated
Evaluation usually starts with morning testosterone testing because levels vary throughout the day. Depending on the clinical situation, Dr. Nazarian may review or order:
- Total testosterone
- Free testosterone when appropriate
- Sex hormone-binding globulin (SHBG)
- Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) when indicated
- Prolactin when clinically appropriate
- Estradiol in selected situations
- Complete blood count and hematocrit
- PSA and prostate assessment when appropriate for age and risk
- Thyroid, metabolic, glucose, and lipid testing when clinically relevant
Diagnosis should generally include compatible symptoms plus appropriately confirmed low testosterone levels rather than a single isolated result.
Testosterone Replacement Therapy (TRT)
TRT is intended to restore testosterone to an appropriate physiologic range in men with confirmed deficiency and a clinical indication. Treatment options may include injections, transdermal preparations, pellets, or other FDA-approved formulations depending on the patient’s medical history, preferences, and treatment goals.
The potential benefits and risks should be discussed before treatment. TRT may improve symptoms in appropriately selected men, but response varies and treatment requires ongoing monitoring.
Fertility and Testosterone Therapy
Exogenous testosterone can suppress sperm production. Men who are actively trying to conceive, may want children in the future, or are uncertain about fertility plans should discuss this before starting TRT. In some situations, alternative strategies may be considered depending on the diagnosis, fertility goals, and specialist input.


Men’s Hormone Optimization Beyond TRT
Not every man with symptoms needs testosterone. A broader hormone and metabolic plan may include improving sleep, treating sleep apnea, addressing excess weight, reviewing medications, correcting nutritional deficiencies when present, optimizing exercise and resistance training, managing diabetes or insulin resistance, and evaluating thyroid or other endocrine conditions when appropriate.
Monitoring During Testosterone Therapy
Follow-up is an essential part of safe TRT. Monitoring may include symptom response, testosterone levels, hematocrit, PSA when appropriate, blood pressure, metabolic risk factors, and side effects. Dose and formulation may be adjusted based on clinical response and laboratory results.
Potential Risks and Side Effects
- Acne or oily skin
- Increased red blood cell count or hematocrit
- Fluid retention
- Changes in fertility and sperm production
- Possible worsening of untreated sleep apnea
- Prostate-related monitoring needs
- Other treatment-specific risks depending on formulation and medical history
Cardiovascular and prostate considerations should be reviewed individually rather than assuming TRT is either universally safe or universally unsafe.
Why Physician Oversight Matters
Testosterone therapy should not be started solely because a patient wants a higher number or because one lab result is below range. Dr. Nazarian reviews the underlying cause, competing diagnoses, fertility goals, cardiovascular and metabolic health, and whether treatment is likely to provide meaningful benefit.

Frequently Asked Questions
Is men’s hormone optimization the same as TRT?
Not exactly. Men’s hormone optimization is the broader evaluation of symptoms, hormone levels, fertility, sleep, metabolism, lifestyle, and other contributors. TRT is one treatment option for men with confirmed testosterone deficiency who are appropriate candidates.
How is low testosterone diagnosed?
Diagnosis generally requires compatible symptoms together with appropriately timed laboratory testing showing consistently low testosterone levels. Additional testing may be needed to identify the cause.
Does TRT affect fertility?
Yes. Exogenous testosterone can suppress sperm production, so fertility goals should be discussed before treatment begins.
How often is TRT monitored?
Monitoring frequency depends on the formulation, dose, baseline risk factors, and treatment response. Laboratory testing and clinical follow-up are typically more frequent during initiation or dose changes.
