What Is Testosterone Replacement Therapy — and Do You Need It?
Testosterone replacement therapy in New Jersey is not one-size-fits-all — and at Princeton Men’s Health, it never is. Dr. Mahmood Siddique, DO, FACP, FCCP, FAASM — quadruple board-certified and a Clinical Associate Professor at Rutgers Robert Wood Johnson Medical School — oversees every patient personally, from your first consultation through ongoing monitoring. Every diagnosis begins with lab work. Every treatment plan is built around your results, your symptoms, and your goals.
Signs of Low Testosterone in Men
Testosterone begins declining at roughly 2% per year after age 30. By your mid-40s, the cumulative effect becomes impossible to ignore. By age 60, most men have lost approximately 25% of their peak testosterone — and 25% will meet the clinical threshold for hypogonadism, defined as a serum level below 300 ng/dL.
Common signs that your testosterone may be low:
- Persistent fatigue that sleep does not fix
- Declining libido or loss of interest in sex
- Weaker or less frequent erections
- Loss of muscle mass despite regular exercise
- Increasing belly fat, particularly around the midsection
- Depression, irritability, or flattened mood
- Brain fog, poor concentration, or memory lapses
- Disrupted or non-restorative sleep
- Decreased motivation and drive
These symptoms rarely arrive alone. Most men present with three, four, or five at once — which is why Dr. Siddique evaluates the full clinical picture, not a single lab value in isolation.
From Dr. Siddique
Why Your Testosterone Is Falling
Testosterone declines roughly 2% every year after the age of 30. By 60, most men have lost about a quarter of what they had — and 38% of men over 45 have levels low enough to matter. Dr. Siddique explains what is actually happening, why it tracks so closely with fatigue, weight gain, poor sleep and low libido, and why a 2023 study in the New England Journal of Medicine found that men aged 45–80 with low testosterone frequently carried multiple cardiovascular risk factors alongside it.

What to Expect From Testosterone Replacement Therapy
Regardless of which delivery method you choose, Dr. Siddique monitors your progress at regular intervals. Follow-up labs include serum testosterone, estradiol, and a complete blood count. Testosterone stimulates red blood cell production, so hematocrit is checked periodically — and if levels rise above the healthy range, Dr. Siddique may recommend donating blood to bring them back into balance. This is a normal, manageable aspect of TRT, not a reason to avoid treatment.
Patient Story
“My Only Regret Is That I Didn’t Start Sooner.”
Tony came to us frustrated. He couldn’t lose weight no matter what he tried. His energy was gone, his stamina had collapsed, and a persistent brain fog made it hard to focus through a normal day.
Rather than treat one symptom in isolation, Dr. Siddique addressed the whole system — testosterone therapy alongside nutrition and body composition analysis. A year on: 35 pounds lost with muscle preserved, workout recovery cut in half, the fog lifted, and his pre-diabetic markers back to normal range.
