Low Testosterone: 7 Warning Signs For Men Over 40


25% of men over 40 years suffer testosterone deficiency. Studies suggest that aside from low sex drive, lack of the hormone puts you at a higher risk of conditions such as diabetes, cardiovascular disease, and osteoporosis.

Why testosterone is so important for men?

Testosterone is the hormone responsible for the development of male sexual characteristics. The hormone is produced in the testicles.

Aside from sperm production, the hormone regulates other body functions such as:

  • Sex drive
  • Production of red blood cells
  • Distribution of fat
  • The building of muscle mass and strength
  • The building of bone mass

Low testosterone treatments

Low T is treatable. The most common treatment is replacement therapy. In most cases, the replacement therapy will address common issues such as poor erections and low libido.

However, if other conditions are causing erectile dysfunction and low sex drive, the doctor should address them too. Otherwise, the treatment will appear not to be working.

Replacement therapy options include:

  • Injections: most patients prefer to buy testosterone injections as they are cheap. These treatments last between 1 and 3 weeks. They can be self-administered, or you can seek the help of a healthcare professional.
  • Gels and patches: you can apply the gel on the skin or stick a patch. Then, the skin absorbs T into the bloodstream.
  • Tablets: you can buy tablets at your local pharmacy. Most come in the form of gum that you place under your lip.

7 warning signs of low T for men over 40

For men above the age of 19, the normal T levels range from 240 to 950 nanograms per deciliter. A simple blood test will reveal your T level. But, like any other medical condition low T has symptoms.

The following are 7 warning signs of low T for men over 40:

Low sex drive

Testosterone has a significant impact on libido or sex drive in men. Of course, as men age, their sex drive diminishes. But, someone with a deficiency of the hormone will experience a rapid drop in their sex drive.

Remember, the hormone stimulates the production of semen. So, another consequence of lack of the hormone is low semen volume during ejaculation.

Erectile dysfunction

The hormone plays a vital role in achieving and maintaining an erection. It stimulates brain receptors to produce nitric oxide, which triggers a series of reactions that lead to an erection. So, the deficiency of the hormone contributes to erectile dysfunction – you have spontaneous erections, and erections do not happen when you need them.

But many other factors contribute to erectile dysfunction. In fact, testosterone treatment is not effective in treating erectile dysfunction in 50% of men. Other factors that cause erection problems include diabetes, high blood pressure, high cholesterol, smoking, stress, and depression.


Low level of the hormone in men causes extreme fatigue. Men suffering this condition also report a drop in energy levels. So, you are likely to feel tired even after getting enough sleep. Also, you will lack the motivation to indulge in physical activities such as exercise.

Loss of muscle mass

The hormone helps in the building of muscle mass. Fortunately, the deficiency of the hormone might not affect strength and function.

Consequently, the deficiency of the hormone leads to increased body fat. And, due to an imbalance between testosterone and estrogen a condition called gynecomastia (enlarged breast tissue) develops.


The hormone influences mental capacity and moods. Its deficiency in men sometimes results in mood changes. According to research, T deficiency causes a lack of focus, increases irritability and makes men more vulnerable to depression.

Hair loss

The hormone influences hair production, which could explain why men are hairier than women. Low levels of the hormone contribute to hair loss – facial and body hair. But, remember balding is a hereditary component common in older men: It is not necessarily a consequence of deficiency of the hormone.

Reduced bone mass

Deficiency of T causes the thinning of bone mass, or osteoporosis, a condition common in women. That is because the hormone helps in the production and strengthening of bones. The reduced bone mass makes you more vulnerable to bone fractures.


Low testosterone is a serious health concern that most men ignore. Remember, as you age, your T levels decrease. So, you should look out for the signs discussed above. If you notice any of the symptoms visit your doctor immediately to discuss your options.
