If you’re a man over 35 and noticing muscle loss, stubborn belly fat, slower recovery, or reduced strength, you’re not imagining it. These changes are often driven by a gradual decline in testosterone, a condition known as age-related hypogonadism.

At Bioidentical Hormones NYC, we specialize in diagnosing and treating hormonal imbalances using advanced lab testing and personalized testosterone therapy—helping men regain muscle mass, energy, and long-term health.

Why Men Lose Muscle Mass After 35

Natural Testosterone Decline

Testosterone levels decline by 1–2% per year after age 30. By 40–50, many men experience levels low enough to impact muscle protein synthesis.

Reduced Muscle Protein Synthesis

Lower testosterone means:

  • Slower muscle repair
  • Reduced muscle fiber growth
  • Increased muscle breakdown

Increased Fat Storage

Low testosterone shifts metabolism toward fat accumulation, especially visceral (abdominal) fat, which further suppresses testosterone.

Lifestyle & Stress Factors

  • Chronic stress → elevated cortisol
  • Poor sleep → reduced testosterone production
  • Sedentary lifestyle → muscle atrophy

Symptoms of Low Testosterone in Men

Common Signs

  • Loss of muscle mass and strength
  • Increased body fat
  • Fatigue and low motivation
  • Brain fog
  • Reduced libido
  • Erectile dysfunction
  • Mood changes or depression

These symptoms often appear years before diagnosis, which is why testing is critical.
