Male Hormone Checkups After 40: What Every Man Should Know

Testosterone is often associated with sexual function, but in truth, it plays a much broader role in men’s overall health. This vital hormone influences energy levels, muscle strength, bone density, red blood cell production, and even mood and emotional well-being. When testosterone levels fall below normal, it can affect daily functioning and significantly reduce quality of life over time.

What is Testosterone?

Testosterone is a male sex hormone primarily produced in the testicles, with small amounts also made by the adrenal glands. It drives many of the physical changes seen during puberty, such as:

• A deeper voice
• Body and facial hair growth
• Increased muscle mass
• Genital development
• Heightened sexual desire

Beyond puberty and sexual function, testosterone is also critical for:

• Maintaining muscle mass and strength
• Supporting bone density
• Stimulating red blood cell production
• Influencing mood, energy, and self-confidence

Does Testosterone Naturally Decline With Age?

Yes. In most men, testosterone levels begin to gradually decrease after the age of 40, with an average drop of 1–2% per year. This decline may accelerate due to factors such as lack of exercise, chronic stress, heavy alcohol use, or poor sleep habits. Long-term deficiency can lead to a condition known as andropause, sometimes referred to as “male menopause.” Symptoms may include:

• Fatigue and low energy
• Irritability or depression
• Reduced libido
• Decreased muscle mass and increased body fat
• Erectile dysfunction or poor sexual performance

Who Should Get Their Testosterone Levels Checked?

Hormone testing isn’t just for men with sexual health issues. You should consider getting tested if you experience:

• Persistent fatigue despite adequate rest
• Unexplained weight gain, especially around the abdomen
• Muscle weakness or reduced physical strength
• Mood swings or unexplained depression
• Low libido or lack of sexual desire
• Difficulty sleeping or staying asleep

Testing is especially recommended for men over 40, or those with chronic conditions such as high blood pressure, diabetes, or high cholesterol, as these can be linked to hormonal imbalances.

How is Testosterone Tested?

Testing testosterone levels is simple and non-invasive. It involves a blood test to measure total testosterone. In some cases, doctors may order additional tests such as:

• SHBG (Sex Hormone Binding Globulin)
• LH (Luteinizing Hormone)

These help assess the overall hormonal balance and function of the endocrine system. Testosterone levels below 300 ng/dL are often considered low and may warrant medical evaluation and treatment.

What Happens If My Testosterone is Low?

If your test results show low testosterone, your doctor may recommend one or more of the following:

1. Lifestyle changes – Regular exercise, weight loss, better sleep habits, reduced alcohol, and quitting smoking
2. Testosterone Replacement Therapy (TRT) – Hormone supplementation via injections, gels, or patches, depending on your health profile and symptoms
3. Ongoing monitoring – Regular blood tests and follow-ups to track progress and ensure safety

Where Can I Get Tested?

Today, many men’s health clinics offer specialized hormone testing services. Clinics like MaxWellness Thailand provide comprehensive hormone assessments, consultations with medical specialists, and personalized care plans tailored to your age, lifestyle, and health status.

Conclusion: Start with a Simple Test, Transform Your Health Checking your testosterone levels isn’t just about improving your sex life—it’s about taking charge of your long-term health. Balanced hormone levels can help you feel more energized, stay mentally sharp, maintain strong muscles, and live a more vibrant life. If you’re over 40 or experiencing unexplained fatigue, low mood, or changes in physical performance, don’t ignore the signs. A simple blood test could be your first step toward a healthier, more powerful version of yourself.
