Testosterone Therapy Q & A

What Is Testosterone?

Testosterone is a steroid hormone, is the main sex hormone in males. Testosterone is primarily produced in the testicles and responsible for the development of male secondary sexual characteristics. Testosterone plays a key role in maintaining physical and mental health in both females and males. Testosterone helps to maintain healthy heart and brain function, to enhance the cardiac benefits of exercise, to build lean muscle mass, to sharpen your memory, to increase the libido and sperm production, and to increase red blood cell production.
Just like your cholesterol or blood pressure, there is a numerical range of testosterone levels (also known as T levels) that are considered normal. The brain and the testicles work together to keep testosterone in this range. When levels of testosterone are below normal, the brain signals the testicles to make more. When testosterone levels reach a normal level, the brain signals the testicles to make less.

Just because you’re getting older, doesn’t mean you have to feel old. As men get older, it is very common to experience weight gain, loss of muscle mass, sexual problems, feelings of depression, a loss of mental sharpness and even a loss of height. Those symptoms can start as early as between the ages of 30-55.

If you have sought treatment for any of these symptoms, more than likely your doctor may have prescribed a prescription medication to “fix” the symptoms. Low testosterone is one of the main reasons of the symptoms/problems. Dr. Davis has been trained and specialized in treating the root/reasons that cause the above symptoms/problems for more than 15 years.

What Happens to Your Testosterone Levels with Age?

The production of Testosterone generally peaks as a male reaches’ adolescence through early adulthood. As men age, Testosterone levels decrease, approximately 1% per year after the age of 30.

How Do I Know If I Have Low Testosterone Levels? 

A simple blood test is the best way to know your Testosterone level, which can be conveniently performed in the office at Texas Anti-Aging Medicine Institute.

What does Testosterone Therapy at Texas Antiaging Center entail?

Each patient’s Testosterone therapy program begins with a medical history review, physical exam, and an InBody scan. The scan provides a valuable and comprehensive body composition analysis-intracellular and extracellular water, muscle, fat, and with zero risk of radiation exposure. The InBody scan is considered to be approximately 98% accurate compared with DEXA, a gold standard in Body Composition Analysis. Combining the scan results and your total & free Testosterone level, as determined by blood and or saliva test, Dr. Davis devises a personalized Testosterone program. This program will be a combination of Testosterone injections or cream, and/or HCG injection, along with detoxification programs including IV Chelation, IV Glutathione, and oral GI detoxification programs, and with IV Nutrition, IV NAD+, as well as weight loss programs, including variation of diet and exercise plans, oral nutritional supplements suggestions, and ongoing evaluations.

What Results Can Be Expected from Testosterone Therapy?

Benefits include an increase in muscle mass, particularly when used in conjunction with a weight loss and weight training program.  This increase in muscle mass will accelerate metabolism, reduce body fat and improve vitality. Decreasing fat also offers numerous health benefits, such as lowering the risk of Type-2 diabetes, cancer, heart disease, and neurodegenerative disease. These benefits translate to improved brain health and mood, increased energy and sexual function, and libido.

Symptoms of Low Testosterone
• Low sex drive (libido)
• Erectile dysfunction
• Fatigue and poor energy level
• Difficulty concentrating
• Depression/anxiety/ADHD
• Irritability
• Low sense of well-being, mental fatigue
• Weight/body fat gain
• Loss muscle even with same exercises or unable to maintain muscle
• Loss interest of career goals, hobbies
• Insomnia, poor sleep quality
• High cholesterol
• Low thyroid, adrenal fatigue

Benefits of Testosterone Therapy

Testosterone Therapy increases muscle mass especially when combined with a resistance training program. More muscle mass and strength mean better metabolism and higher quality of life. Most men report better recovery from their workouts and find that they can work out more intensely once started on testosterone replacement therapy.

The increased metabolism resulting from increased muscle reduces fat and improves overall body composition. By reducing fat, the risks of diabetes, hypertension, cancer, and heart disease go down.

A high concentration of testosterone receptors exists in the brain. Testosterone is essential for healthy brain function and can improve mood swings and irritability that many men experience as well as depression. Men sometimes display indecisiveness and loss of confidence with aging, both of which can be improved with testosterone therapy.


Testosterone Therapy has many cardiovascular benefits. The highest concentration of testosterone receptors is in the heart. Which makes sense since the heart is a muscle that is contracting roughly ever second. Testosterone improves blood flow by acting as a vasodilator and helps to repair damaged endothelium or inner lining of blood vessels. Testosterone can help lower blood pressure.

Diabetes and Low Testosterone
A link between diabetes and low testosterone is well established. Men with diabetes are more likely to have low testosterone. And men with low testosterone are more likely to later develop diabetes. Testosterone helps the body’s tissues take up more blood sugar in response to insulin. Men with low testosterone more often have insulin resistance: they need to produce more insulin to keep blood sugar normal.

Obesity and Low Testosterone


Obesity and low testosterone are tightly linked. Obese men are more likely to have low testosterone. Men with very low testosterone are also more likely to become obese.
Fat cells metabolize testosterone to estrogen, lowering testosterone levels. Also, obesity reduces levels of sex hormone binding globulin (SHBG), a protein that carries testosterone in the blood. Less SHBG means less testosterone.
Losing weight through exercise can increase testosterone levels. Testosterone Therapy in men with low testosterone can also reduce obesity slightly.

Metabolic Syndrome and Low Testosterone


Metabolic syndrome is the name for a condition that includes the presence of abnormal cholesterol levels, high blood pressure, waistline obesity, and high blood sugar. Metabolic syndrome increases the risk for heart attacks and strokes.
Studies show that men with low testosterone are more likely to develop metabolic syndrome. Testosterone therapy improves blood sugar levels and obesity in men with low testosterone.

Testosterone and Heart Disease

Testosterone deficiency is connected to insulin resistance, obesity, and diabetes. Each of these problems increases cardiovascular risk. Men with diabetes and low testosterone also have higher rates of atherosclerosis, or hardening of the arteries.
A certain amount of testosterone may be necessary for healthy arteries because it’s converted into estrogen, which protects arteries from damage.

Testosterone and Other Conditions


Low testosterone often exists with other medical conditions:
Depression: In a study of almost 4,000 men older than 70, those with the lowest testosterone levels were more than twice as likely to be depressed. This link remained even after allowing for age, general health, obesity, and other variables.
Erectile dysfunction (ED): Problems with erections are one of the most common symptoms of low testosterone. Most ED is caused by atherosclerosis. Men with risk factors for atherosclerosis — diabetes, metabolic syndrome, or obesity — often have low testosterone, too.
High blood pressure: The effects of testosterone on blood pressure are many and complex. Men with high blood pressure may be almost twice as likely to have low testosterone as men with normal blood pressure. On the other hand, too much testosterone can increase blood pressure. Testosterone acts in multiple ways on blood vessels, so this may account for the varying effects.
