Feeling drained, irritable, or struggling to maintain your energy levels? Low testosterone levels could be the cause. Dr. Dana Cohen, MD, a leading integrative and functional medical doctor in NYC, takes a holistic approach to testosterone replacement therapy. With over 20 years of experience helping men regain their vitality, Dr. Cohen provides personalized treatments that address the root causes, helping you lead a healthier, more balanced life.
What Is Testosterone Replacement Therapy?
Testosterone replacement therapy (TRT) is a medically supervised treatment designed to restore healthy testosterone levels in men experiencing low testosterone, also known as hypogonadism. Low testosterone generally occurs due to natural aging, medical conditions, or lifestyle factors.
TRT involves safely introducing bioidentical testosterone into the body to alleviate symptoms such as fatigue, reduced libido, and difficulty maintaining muscle mass. Dr. Cohen focuses on integrating this therapy into a holistic health plan, optimizing not only testosterone levels but also overall well-being. By using a blend of traditional medicine and functional, science-backed approaches, TRT can effectively regain energy, confidence, and vitality.

Recognizing the Symptoms of Low Testosterone
Identifying low testosterone early is key to effective treatment. Here are common symptoms to watch out for:
- Low Energy Levels - Does it feel like you never have enough energy to get through the day? Men with low testosterone often experience chronic fatigue, even after a good night’s sleep.
- Decreased Libido - Changes in sexual desire can be a natural part of aging, but severe or sudden drops in libido often indicate hormonal imbalances like low testosterone.
- Mood Changes - Irritability, depression, or sudden mood swings can signal hormonal shifts. Low testosterone directly impacts neurotransmitters, affecting mental health and mood stability.
- Muscle Loss and Weight Gain - Struggling to build or maintain muscle mass? Low testosterone interferes with muscle repair and can also lead to increased fat storage.
- Cognitive Decline - Difficulty focusing, poor memory, or mental fog might be more than early signs of aging. Testosterone plays a critical role in maintaining brain function.
Common Causes of Low Testosterone
A variety of factors contribute to low testosterone. Identifying these causes is essential to developing a personalized treatment plan.
- Aging - From age 30, testosterone levels naturally begin to decline at about 1% per year. This gradual decrease can lead to noticeable symptoms over time.
- Chronic Stress - High stress affects hormonal balance. Elevated cortisol levels can suppress testosterone production, leading to chronic deficiencies.
- Health Conditions - Diabetes, obesity, and metabolic syndrome are all linked to lower testosterone levels. Addressing these conditions often improves hormonal health.
- Poor Sleep Patterns - Sleep deprivation or disorders like sleep apnea can disrupt testosterone production, as the hormone is primarily produced during deep sleep phases.
- Nutritional Deficiencies - Diet matters, too. Lacking essential nutrients like zinc, magnesium, and vitamin D can hinder testosterone production.

Dr. Cohen’s Holistic Approach to Testosterone Replacement Therapy
At her Manhattan-based practice, Dr. Dana Cohen takes a comprehensive, patient-focused approach to testosterone replacement therapy. She begins with an in-depth consultation to understand your symptoms, medical history, and lifestyle. Next, she conducts advanced diagnostic testing to assess testosterone levels and identify potential contributing factors like nutrient deficiencies or underlying health issues.
Unlike traditional treatments that rely solely on hormones, Dr. Cohen integrates holistic practices into your therapy. She focuses on improving the whole body by pairing hormone therapy with complementary strategies such as dietary recommendations, stress management, and personalized exercise plans. All treatments use high-quality, bioidentical testosterone to ensure safe and effective results.
This collaborative and well-rounded approach doesn’t just focus on alleviating your current symptoms but also ensures long-term improvements in your overall health.
How Long Does Testosterone Replacement Therapy Take to Work?
Testosterone replacement therapy often delivers noticeable results within the first few weeks. Many patients report improved energy, better moods, and increased motivation in as little as three to four weeks. Physical changes, such as enhanced muscle strength and reduced body fat, typically emerge after two to three months of consistent therapy. Libido improvements and mood stabilization may occur earlier but can vary from person to person.
The timeline for results depends on several factors, including your body’s response to treatment, adherence to complementary therapies, and underlying medical conditions. Regular follow-ups with Dr. Cohen will ensure adjustments are made to optimize your progress.
Possible Side Effects of Testosterone Replacement Therapy
Testosterone therapy is generally safe when administered under medical supervision. However, as with any treatment, there are potential side effects.
- Some men may experience mild fluid retention, acne, or an increase in red blood cell count. Dr. Cohen takes every precaution by closely monitoring every phase of your therapy through regular blood tests and assessments.
- More serious side effects are rare but may involve imbalances in estrogen levels, which Dr. Cohen manages proactively by fine-tuning your treatment plan. Rest assured, your health and safety are her top priorities.
