Optimum Testosterone levels in Men

Optimum Testosterone levels in Men
by Dr. Nasir Asghar


Testosterone is the primary sex hormone in the male and has multi-function purposes.

Its levels are 7-8 times greater in men as compared to females. The healthy range of testosterone in the male is between 400-600 ng/dl.

Testosterone hormones function in the adult male to regulate muscle mass, fat distribution, sperm production, mood/behavior and production of red blood cells.

Decreased testosterone in the male can subsequently lead to irritability, low libido, and decrease muscle mass and increase fat distribution.

Conversely, high levels of testosterone can lead to aggressive behavior, increase red blood cells, increased male pattern baldness, acne and increased risk of blood clots and worsening of sleep apnea.

Sources of Testosterone deficiency in men range from increasing age, pituitary tumor, iron storage disease, sleep apnea, depression, thyroid disease, alcoholism, sedentary life style and diabetes.

Major remedies to increase testosterone include,

  1. Starting an exercise regimen including weight training but NOT endurance training (may lead to decrease testosterone)
  2. a proper diet
    • Decrease sugars
    • Increase vegetables
    • Stopping night time feedings

  3. Controlling diabetes
  4. Weight management (decrease body fat)
  5. Treating sleep Apnea.
  6. Vitamin supplement have NOT showed to increase testosterone.

There is also prescription testosterone (gels, injections, pellets) that can be used as a last resort. They can significantly help with symptoms of Low T levels, but must be used with caution and be maintained within the limits of normal range to avoid major side effects as listed above.

Lab work must be checked every 3-6 month to follow the red blood cells, prostate and cholesterol levels.

Starting with a healthy life-style and annual checkups is best way to maintain an optimum testosterone level for a long and healthy life.
