Test your Testosterone

You can argue that testosterone makes you manly, as it is often considered the “male hormone” because it is responsible for the development of your sex organs and your sexual characteristics.

You can argue that testosterone makes you manly, as it is often considered the “male hormone” because it is responsible for the development of your sex organs and your sexual characteristics.1 Yet, it also serves many other important functions in the body including: contributing to muscle and bone development, immunity, and brain function.2 

So – what happens when you begin losing testosterone?  Starting between the ages of 30-40, men’s testosterone levels begin to slowly decline.2-4 

The term for low testosterone is called “hypogonadism” and the result is what some call Male Menopause, also known as “Andropause”.  

Low Testosterone – Symptoms 

Low levels of testosterone may result in the following symptoms:2

  • weakness
  • fatigue
  • loss of sexual desire/function
  • mood disorders
  • insomnia 
  • flushes 
  • lack of motivation 

Bones, Blood & Brains

Because of the other important functions testosterone plays, when it starts to lower, this has effects on the bones, blood cells, and brain.

Osteoporosis:  It is estimated that 1 in 5 men will suffer from a broken bone as a result of osteoporosis.5  This may relate to the levels of testosterone men have in their bodies.  Testosterone signals muscles to grow, which promotes building strong bones.6 When testosterone levels decline, there is an increased risk of weakened bones.  

Anemia:  Testosterone is responsible for producing erythropoietin, which is a hormone that stimulates red blood cell formation.2 Low testosterone levels can result in a decline in red blood cell formation, which can result in anemia and contribute to weakness and fatigue.2

Mood & Wellbeing: Losing your sexual desire and motivation can result in depression and general irritability.2 Research suggests that testosterone may act directly on the brain in men with andropause to improve mood, or it may just be an effect of improving other symptoms.2

Managing the Change

There are several things to consider if you have low testosterone levels. 

Medication

Some health care practitioners may prescribe testosterone replacement therapies to help increase your testosterone levels. However, this is a controversial topic and one that you should consult with your health care provider.

Life Style 

Physical activity and nutrition are two key areas of managing andropause.  

Physical Activity

A specific exercise program may be designed for you to help increase your testosterone levels. High intensity, cardiovascular exercise may lower testosterone.7 A health care professional (doctor, kinesiologist, physiotherapist) may be able to provide you with information on which exercises stimulate increases in testosterone.7 

In general, a balance of cardio, resistance training, stretching and yoga is recommended.7 Weight bearing physical activity (such as jogging or jumping rope) is also very important to prevent osteoporosis. 

Nutrition

Many vitamins and minerals are important in keeping testosterone levels balanced in the body. Below are a few examples.

Zinc
This is an extremely important nutrient for ensuring a balance between testosterone and estrogen in the body. Without zinc, the human body will convert some testosterone into estrogens, which further depletes their level.8,10   
Food Sources of Zinc:  Beef, pork, lamb, dark meat of chicken, nuts, whole grains, legumes9 

Vitamin C
This antioxidant works in a similar way as zinc to prevent the conversion of testosterone to estrogens.8 
Food Sources of Vitamin C: dark leafy greens (kale, spinach, rapini), red & yellow peppers, pineapples, grape fruits, berries11

Vitamin A & E 
Some experts suggest that these vitamins may also play a role in enhancing testosterone production.10 
Food Sources of Vitamin A: Liver (chicken, beef, etc.), spinach, carrots, sweet potatoes12

Food Sources of Vitamin E: dark leafy greens, sunflower seeds, almonds, fish (halibut, sardines, tuna), eggs13 

No matter what you call it, male menopause is a natural part of aging. Maybe it’s time to test your testosterone! Don’t be shy to discuss this with your friends, family or doctor.  It’s something you can manage to continue to live a healthy, vibrant life!
