When was your last annual checkup? For many men, scheduling a yearly visit to the doctor often falls to the bottom of the priority list. Yet, regular checkups are critical for staying on top of your health, especially as you age. One often-overlooked aspect of these visits is testosterone testing — a vital tool for understanding your energy levels, mental clarity, and overall health.
Testosterone is more than just a male sex hormone. It plays a significant role in everything from metabolism to mental focus. Including testosterone testing in your yearly doctor checkup can help you identify imbalances early and make informed decisions about your health.
What Happens During an Annual Checkup?
Your yearly checkup doctor visit is more than just a box to tick. It’s an opportunity to assess your overall health, discuss any new symptoms, and screen for common conditions. During these visits, a healthcare provider typically checks vital signs, performs a physical exam, and orders blood tests to evaluate key health markers.
For men, testosterone testing should be one of these routine evaluations. Testosterone levels naturally decline with age, but sometimes the drop is faster than expected, leading to symptoms like fatigue, low libido, and trouble concentrating.
How Often Should You Get Routine Checkups at the Doctor?
Experts recommend scheduling a general checkup at least once a year. However, depending on your age and medical history, your doctor may suggest more frequent visits. These checkups allow your provider to track changes in your health over time and identify potential issues early on.
Why Does Testosterone Testing Matter?
Testosterone testing provides insight into your hormone health. Low testosterone levels can impact everything from your mood to your physical stamina. During your annual checkup, a simple blood test can measure both total and free testosterone levels, giving your doctor a comprehensive picture of your hormonal health.
What is the Difference Between Free and Total Testosterone Levels?
Testosterone in your body exists in two primary forms: bound testosterone and free testosterone. Together, these make up your total testosterone levels, which reflect the overall amount of testosterone circulating in your bloodstream. However, not all of this testosterone is readily available for your body to use.
Total Testosterone
This includes testosterone bound to proteins like sex hormone-binding globulin (SHBG) and albumin, as well as free testosterone. Bound testosterone is largely inactive because it is "locked" to these proteins and unavailable for immediate use.
Free Testosterone
This represents the small percentage of testosterone that is unbound and actively available for your body to use. Free testosterone is what directly impacts functions like energy, mood, muscle growth, and libido.
Knowing both your total and free testosterone levels is crucial for a complete understanding of your hormonal health. For instance, normal total testosterone levels generally range between 300–1,000 ng/dL. While free testosterone levels are difficult to directly measure, levels less than 50–65 picogram per milliliter (pg/mL) are considered low.
Why Does the Difference Matter?
While total testosterone gives a broad overview of your hormone levels, free testosterone provides a clearer picture of how much testosterone your body can actively use.
For example, a man with normal total testosterone but low free testosterone may still experience symptoms of low T, such as fatigue, trouble focusing, or low libido.
Measuring both levels can help your doctor determine whether an imbalance is caused by low production or increased binding by SHBG, which often occurs with age or certain medical conditions.
Do Testosterone Levels Fluctuate?
Yes, testosterone levels naturally fluctuate based on factors like sleep, stress, and time of day. Levels are usually highest in the morning, which is why doctors often recommend getting tested early in the day. Regular monitoring through annual checkups ensures these fluctuations remain within healthy limits.
How Testosterone Impacts Your Health
Testosterone affects nearly every aspect of men’s health, including:
1. Energy and Stamina
Low testosterone can lead to chronic fatigue, reduced stamina, and longer recovery times after physical activity. Restoring healthy levels can boost energy, making it easier to stay active throughout the day.
2. Mental Clarity
Testosterone supports cognitive functions like memory, spatial cognition, and problem-solving. Men with low testosterone often report brain fog, trouble focusing, and difficulty retaining information. Balanced levels can improve mental sharpness, making daily tasks and complex challenges easier to manage.
3. Sexual Health
Testosterone is crucial for men’s sexual health, influencing libido, erectile function, and overall satisfaction. Low testosterone can cause decreased interest in intimacy and performance difficulties, which may affect relationships. Addressing imbalances can help restore confidence and improve connection with a partner.
4. Muscle Mass and Bone Health
Testosterone aids in muscle protein synthesis, helping repair and grow muscles, and supports bone density to prevent conditions like osteoporosis. Low testosterone levels can lead to muscle loss, reduced strength, and weaker bones, increasing the risk of fractures as you age.
5. Emotional Resilience
Testosterone influences mood and emotional stability, with low levels linked to irritability, depression, and anxiety. Optimizing testosterone can improve emotional resilience, helping you manage stress, stay motivated, and maintain healthy relationships.
6. Metabolism and Weight Management
Testosterone regulates metabolism and fat distribution, with low levels often leading to weight gain, particularly around the midsection. Men with healthy testosterone levels may burn fat more efficiently, maintain lean muscle, and find it easier to manage weight.
Where Can I Get My Testosterone Levels Checked?
While some primary care providers and endocrinologists offer testosterone testing as part of an annual checkup, most may not offer it unless prompted by the patient. Advocate for your health by asking your yearly checkup doctor to include testosterone testing in your routine bloodwork. Specialized men’s health clinics also offer hormone testing, often with additional support for testosterone replacement therapy if needed.
Other Important Tests During an Annual Checkup
January is Thyroid Awareness Month, making it the perfect time to address thyroid health during your annual exam. Thyroid imbalances can mimic symptoms of low testosterone, such as fatigue, weight gain, and mood changes. Including a thyroid panel in your routine bloodwork ensures your doctor gets a complete picture of your hormone health.
Questions to Ask Your Doctor During a Checkup
To get the most out of your annual exam, consider preparing a list of questions to ask your doctor. Examples include:
- “Should I get my testosterone levels checked based on my symptoms?”
- “What are my options if my testosterone is low?”
- “What’s the difference between my total and free testosterone?”
- “How do my thyroid levels look, and could they be affecting my energy?”
Take Control of Your Health in 2025
Your annual checkup is an opportunity to take control of your health and make informed decisions about your well-being. Including testosterone testing as part of your routine visit can provide valuable insights into your energy levels, mental clarity, and long-term health. Combine this with thyroid testing and other key screenings to create a comprehensive approach to staying healthy.
