Many important functions are performed by the hormone, including:

  • The development of bones and muscles
  • The deepening and growth of the voice and hair, as well as other aspects related to appearance.
  • The production of sperm
  • As we age, testosterone production may slow down. Many older men experience symptoms of low testosterone.
  • Low testosterone is defined by the American Urology Association as less than 300 nanograms of hormone per deciliter (dl). According to them, about 2 out of 100 men have low testosterone.

When should you see a doctor?


If a patient has a variety of symptoms, a doctor might prescribe testosterone replacement therapy.

Low testosterone is not always accompanied by symptoms. Some people are only aware of it after routine bloodwork and a physical exam.

Anyone who has any of these symptoms should see a doctor immediately.

A doctor will usually perform a physical exam and review the patient’s symptoms to diagnose low testosterone. A doctor might request additional testing to check for other signs.

A bone density test, for example, can reveal a decreased bone mass as a result of low testosterone.



Testosterone replacement therapy (TRT) is the most popular treatment.

TRT is usually only prescribed by a doctor if there are several symptoms that suggest low testosterone or blood tests that show a deficiency.

TRT can be delivered in many ways, including:

  • Skin patches
  • Gels
  • Tablets that dissolve in your mouth
  • Injections

Implanted pellets that release the hormone are surgically placed

Most people notice relief within 4-6 weeks after starting TRT.

Natural methods to increase testosterone levels

A nutrient-rich diet is a good way to increase testosterone levels.

Exercise and weight loss can increase testosterone levels.

Although lifestyle and diet changes alone will not make levels rise enough, they can be helpful.

Keep in mind that testosterone levels drop as men age. Lifestyle changes can also have a negative impact on your ability to get the benefits you desire. For example, exercise often has more impact on younger people.

A diet rich in nutrients is essential to support testosterone levels. You might consider the following foods:

  • Beef
  • Oysters
  • Fortified cereals
  • Eggs
  • Tuna
  • Milk enriched with vitamin D
  • Beans
  • Shellfish

Natural supplements promising to boost testosterone levels should be avoided. They may not cause harm to the body but they are unlikely that they will produce the desired results.

Doctors can often recommend safe ways to increase testosterone levels.


According to the American Urology Association, around 2 of 100 men are affected by low testosterone. Although the risk of low testosterone increases with age, most men lose testosterone naturally as they get older.

Low testosterone is usually treatable. Being aware of symptoms can help you get an early diagnosis and treatment.
