Testosterone

Why has testosterone in men declined year after year for the past 5 decades? More men each
year are diagnosed with low T than ever before. Testosterone has declined by 1% each year
over the past 50 years. The average testosterone of a man 50 years ago was 50 points higher
than a man today. The average testosterone of a 35-year-old man today is approximately
475ng/dL. The average testosterone of a 35-year-old man in 1970 was 525ng/dL. The decline of
testosterone may have several different reasons, and here are a few:

  1. Lifestyle Changes: Modern lifestyles, including increased sedentary behavior, lack of
    physical activity, poor sleep patterns, and unhealthy dietary choices, may play a role in
    declining testosterone levels.
  2. Obesity: The rise in obesity rates worldwide has been associated with lower
    testosterone levels. Excess body fat, especially abdominal fat, can lead to hormonal
    imbalances and decreased testosterone production.
  3. Environmental Factors: Exposure to certain environmental chemicals, such as
    endocrine-disrupting compounds found in plastics, pesticides, and industrial pollutants, has
    been linked to hormonal disruptions, including lower testosterone levels.
  4. Stress: Chronic stress, both psychological and physiological, can negatively impact
    hormone production and regulation, potentially leading to lower testosterone levels.
  5. Aging: Testosterone levels naturally decline with age. However, the observed decline in
    testosterone over the past 50 years appears to be steeper than what can be attributed solely
    to the aging process.

Testosterone levels aren’t the only problem. Sperm counts are also dropping significantly, and
some reproductive disorders, like testicular cancer have increased.

If you are concerned about your testosterone, it may be a good idea to do the following:

  1. Stop using plastic bottles and containers completely.
  2. Stop using products that have chemicals or ingredients you are unfamiliar with. This means
    deodorant, shampoo, detergents, toothpaste, cologne, lotions, gels, and any other products you
    put on your body must be all natural with no chemicals or ingredients that you do not recognize.
  3. Implement a testosterone increasing training and workout plan.
  4. Lower your stress.
  5. Consume the necessary vitamins, minerals, and foods that will support testosterone
    production.
