Among the possible symptoms that indicate low testosterone in men, some can be seen with the naked eye, such as alopecia, loss of muscle mass or increased body fat. Others, on the other hand, require an exam to be determined. For example, bone density and sperm count.

However, this drop in hormone levels is usually gradual over time compared to the abrupt drop in estrogen experienced by women during menopause. However, in both cases quality of life can be affected.

Read on for more details regarding the symptoms that indicate low testosterone in men and what this decreased production of the hormone implies.

What is testosterone and what is its function?

Testosterone is the male sex hormone. Although women have it too, just at much lower levels. In the case of men, It is produced by the testicles and the adrenal glands..

As for their functions, they are related to the following:

  • Sexual functioning: development, sperm production, desire (libido).
  • male characters secondary: voice, hair
  • dough maintenance muscle and bone.
  • Regulation of blood cells, lowering cholesterol, acceleration of metabolism.

Causes of low testosterone in men

To determine the levels of this hormone, a test called circulating serum testosterone test. The normal range is between 300 and 1,000 nanograms per deciliter (ng/dL). Low testosterone is considered when it is below 300 ng/dL.

This can be due to various factors. First, the production of the male hormone decreases with age. It is estimated that 20% of those over 60 years of age have low levels, as well as 30% of men between 70 and 80 years of age, according to the guidelines of the American Urological Association (AUA).

Second is the so-called testosterone deficiency syndrome (SDT), which is not necessarily associated with age, but with other factors:

  • Drug reactions.
  • Chemotherapy.
  • Testicular injuries.
  • Testicular cancer.
  • Disorders in the hypothalamus or pituitary.
  • hypothyroidism
  • Obesity.
Some men have low testosterone levels due to obesity, which interacts in a complex way with the hormonal system.

Symptoms Indicating Low Testosterone in Men

If testosterone falls below the minimum levels noted above, a variety of symptoms may be experienced. Some are more noticeable than others.

1. Erectile dysfunction

testosterone is related to the maintenance and quality of the erection. Although it does not act on its own, it stimulates receptors in the brain to produce nitric oxide.

Now, low testosterone levels are among the factors associated with erectile dysfunction, along with others such as high blood pressure, diabetes, high cholesterol, alcohol and tobacco use, anxiety, and depression.

2. Low libido

As mentioned, the male hormone is related to libido in men. In this sense, a decrease in sexual desire can be evidenced.

3. Little semen production

Another symptom related to sexual functioning and that may indicate low testosterone in men is decreased semen production. This it is something that can even be noticed when ejaculating.

4. Sperm count

Although this hormone is important for the production of sperm, it should be noted that low testosterone is not necessarily one of the causes of infertility in men, as there are many other factors associated with this problem. However, in laboratory studies it was observed with animals treated with an extract of maca that serum testosterone concentration increases along with sperm count.

5. Alopecia

The relationship of testosterone to hair is somewhat complex. Yes OK this hormone is linked to hair (for this reason there is more in the body of men than in women), it can also affect the appearance of alopecia.

It is appropriate to point out that it is not testosterone that is responsible for alopecia, but rather a by-product of it, resulting from its interaction with the enzyme 5-alpha reductase. It is dihydrotestosterone.

6. Muscle mass

Another of the functions of the male hormone is related to the maintenance of muscle mass, which decreases when there is low testosterone. But nevertheless, this does not affect muscle tone or function.

7. Fatigue

In relation to this hormone, low levels are also often associated with feelings of low energy and symptoms of fatigue, both in older men and in those with testosterone deficiency syndrome.

8. Body fat

According to research on the subject, treatments aimed at increasing testosterone levels show a significant reduction in total body fat. This confirms that there is a relationship between both variables.

9. Bone density

Although osteoporosis is often associated with women over the age of 50, loss of bone density can occur in men with low testosterone. The aforementioned study mentions bone strengthening as an effect of testosterone therapies.

10. Size of the testicles

Among its various functions, the male hormone also affects the development and size of the sexual organs. Therefore, low testosterone would show up in the size of the testicles, which may be smaller than average.

11. Gynecomastia

When there is low testosterone, men can develop gynecomastia, a condition that expresses itself with an enlargement of breast tissue. According to studies on the subject, may be due to androgen deficiency, estrogen excess or an imbalance between both types of hormones.

The presence of gynecomastia makes it necessary to evaluate testosterone levels in a male.

12. Low blood counts

Too low testosterone has been linked to an increased chance of anemia. In research with men over the age of 70, treatment with this hormone resulted in an increase in hemoglobin.

13. Mood

The male hormone influences mood. Therefore, men with low testosterone may experience mood swings, irritability, outbursts of anger, and even depression.

14. Cognitive functioning and memory

Cognitive functions, attention and memory in general have been observed to decline with age. Testosterone is thought to play a role in this process.

However, more research on the subject is still required. The studies carried out so far are not conclusive.

What to do when testosterone is low?

When testosterone levels are below the minimum level, some of the aforementioned symptoms will be experienced to some degree. In this case, blood tests may be done and the doctor will recommend treatmentif required.

Of course, the potential benefits and risks of testosterone therapy need to be weighed. You can even consider options to naturally increase this important hormone.
