Is it Ageing or Low-T? The 7-Point Checklist for Men Over 40
How do I know if I have low testosterone? Common symptoms of Low-T in Singaporean men include persistent fatigue, reduced morning erections, and difficulty losing abdominal fat. If you experience 3 or more of these signs, a Total + Free Testosterone blood test is recommended.

The “Over-40” Symptom Checklist
Check if you are experiencing any of the following:
[ ] The “3 PM Slump”: You feel exhausted mid-afternoon despite having a full night’s sleep.
[ ] Loss of Morning Wood: A noticeable decrease in the frequency or quality of morning erections.
[ ] Stubborn Belly Fat: You are gaining weight around the midsection despite no change in diet.
[ ] Reduced Motivation: You find it harder to focus at work or feel less “driven” in your career.
[ ] Irritability: Frequent mood swings or feeling “snappy” with family and colleagues.
[ ] Slow Recovery: Muscles stay sore for days after a simple workout.
[ ] Brain Fog: Difficulty remembering names or staying sharp during meetings.
The “Hidden” Signs: Why a Blood Test is Essential
Symptoms alone aren’t enough for a diagnosis because they often overlap with stress or “burnout.” In our clinic, we look for:
- Total Testosterone: The total amount in your bloodstream.
- Free Testosterone: The “active” hormone available for your body to use.
- SHBG: A protein that can “trap” testosterone, making it unusable.
Next Steps for Men in Singapore
If your checklist is mostly “Yes,” the next step is a simple clinical assessment.
Pro-Tip: Ensure your test is done before 10 AM. Testosterone levels are diurnal; testing in the afternoon can give a “false low” reading that doesn’t reflect your true health status.
