Low Testosterone in Men: Signs, Testing, and Treatment in South Florida

Low testosterone — also known as hypogonadism or "Low T" — is a condition that affects millions of men, particularly those over 40. Symptoms can be subtle and easily attributed to stress or aging, but untreated low testosterone can have significant impacts on physical health, mental well-being, and quality of life. Dr. Christopher Vendryes, MD in Plantation, FL provides comprehensive testosterone evaluation and evidence-based treatment for men throughout Broward County and South Florida.

What Is Low Testosterone?

Testosterone is the primary male sex hormone, responsible for muscle mass, bone density, fat distribution, red blood cell production, sex drive, and sperm production. Testosterone levels naturally decline about 1% per year after age 30, but some men experience a more significant drop that produces noticeable symptoms. A blood testosterone level below 300 ng/dL is generally considered low, though symptoms can occur at higher levels depending on the individual.

Recognizing the Signs

Low testosterone can manifest in many ways: decreased libido and sexual function, erectile dysfunction, fatigue and low energy, loss of muscle mass and increased body fat, mood changes including irritability and depression, difficulty concentrating ("brain fog"), decreased bone density, and reduced body and facial hair. Many men live with these symptoms for years before seeking evaluation, not realizing that an effective treatment exists.

Getting Tested

Dr. Vendryes recommends testosterone testing for men experiencing any combination of the above symptoms. Testing involves a simple morning blood draw — testosterone levels are highest in the early morning, so testing before 10 AM provides the most accurate results. A comprehensive hormonal panel may also include free testosterone, LH, FSH, prolactin, and estradiol to determine the underlying cause of low levels.

Treatment Options

Testosterone replacement therapy (TRT) is available in several forms: topical gels applied daily, intramuscular injections (weekly or biweekly), subcutaneous pellets implanted every 3–6 months, and nasal gels. Dr. Vendryes works with each patient to determine the best delivery method based on lifestyle, preferences, and medical history. Regular monitoring of testosterone levels, hematocrit, PSA, and liver function ensures safe, optimized therapy.

Important Considerations

TRT is not appropriate for all men. It can reduce sperm production, making it unsuitable for men who desire future fertility — in these cases, alternative treatments such as clomiphene citrate or hCG may be recommended. Dr. Vendryes takes a personalized approach, carefully weighing the benefits and risks for each patient and monitoring for potential side effects including elevated red blood cell counts and changes in prostate health.

Lifestyle Factors That Boost Testosterone

In addition to medical treatment, several lifestyle modifications can support healthy testosterone levels: resistance training and regular exercise, maintaining a healthy weight, getting 7–9 hours of quality sleep, managing stress, limiting alcohol consumption, and ensuring adequate vitamin D and zinc intake. Dr. Vendryes incorporates these recommendations into every treatment plan for comprehensive results.
