From the age of 30-35, testosterone levels in men decrease by 1-3% per year.

Low testosterone is not only due to genetic causes, but is also influenced by diet and physical activity.

Symptoms of low testosterone include mood swings, hair loss, early muscle fatigue, among others. Current medicine has given the name to andropause of this period. A process equivalent to menopause in women. (1)

This article discusses the symptoms and causes of low testosterone in men and what to do when it occurs.

Symptoms of low testosterone in men

Symptoms of low testosterone in men

When a man has low testosterone, he experiences all sorts of symptoms. Low libido, lower sperm volume, even hair loss and mood swings. In special cases, doctors should prescribe medication to relieve these symptoms. The symptoms of low testosterone are:

1. Lower sperm volume

The greater the production of male sex hormone, the more sperm a person makes. When you have low testosterone, the period between ejaculations does not change, but the amount and volume of semen change. (4)

2. Erection problems

A healthy man should have an erection in the morning at least 3-4 times a week. This is not one of the first symptoms when low testosterone levels appear in the body.

3. Hair loss

Low  testosterone and baldness  are two closely related processes. When testosterone falls, hair follicles change as they fall.

4.  Mood swings

Low testosterone is accompanied by changes in the levels of other hormones. For example, the hormone  serotonin  can fluctuate your levels irregularly. For this reason, men with low testosterone have a greater problem with attention, and go from a state of euphoria to complete calm in a matter of minutes.

5.  Memory problems

One of the symptoms of low testosterone is memory problems. An investigation by the American Medical Association has shown that memory is one of the factors most affected. This is obviously the cause of changes in brain function. (3)

6.  Fatigue and less muscle development

The feeling of constant fatigue and greater difficulty in training is one of the most common symptoms of low testosterone. It is recommended in these cases to observe the rest days and to supplement them with  methods of muscle recovery  .

7.  Anemia

It has been shown that low testosterone levels can directly affect the amount of hemoglobin in the blood. One study found lower hemoglobin in men with low testosterone than in men who had normal values. (5)

Causes of low testosterone

Stress and anxiety are the two main causes of low testosterone. This is due to the fact that when there is stress, there is an increase in the levels of   the stress hormone , cortisol  . This hormone acts in the opposite way to melatonin and indirectly affects testosterone.

In addition,  foods with magnesium  and zinc are essential for regulating their synthesis. Lack of food with these minerals is the cause of low testosterone, which can be easily attacked.

Lack of  vitamin D  is another reason for the low testosterone. Vitamin D is not only a vitamin but also a hormone and is closely related to testosterone. Taking 15 minutes of sun every day can help you solve this problem.

The use of  anabolic steroids  or other drugs that can rapidly increase testosterone may be the cause of long-term low testosterone levels. They should only be used by men with chronic and / or genetic problems with low testosterone, always with a doctor's permission.

Treatments for men with low testosterone

To avoid low testosterone in men, you need to  sleep well  and eat a proper diet. The inclusion of foods with magnesium and zinc is essential to regulate their synthesis.

Regarding  poppy  , tribulus teresis and other natural supplements, no study has been able to confirm their effect as being able to  increase testosterone  . However, they can promote the quantity and quality of sperm.

In  sleep  , light sleep and other  sleep disorders  are one of the symptoms of low testosterone. Keeping the  number of hours of sleep  and changing the  sleeping position  can help regulate this process.

However, the treatment of men with low testosterone should be determined by a specialist. The reasons may be different and the treatment should be specific to each man.

Antiandrogens - drugs that lower testosterone

Anti-  androgens  are drugs capable of lowering testosterone. People who are born male naturally have higher concentrations of androgens.

Antiandrogens are used in combination with other drugs to treat cancer to reduce the effects of masculinization in transgender people and after certain types of surgery.

The basis of antiandrogen function is the binding of protein receptors called androgen receptors. By binding, they block the effects of testosterone. After all, they are drugs that can reduce the levels of free testosterone in the blood.


Low testosterone is a natural phenomenon that happens over the years.

An excessive drop in testosterone levels can be due to nutritional or behavioral reasons: poor diet and stress.

Providing enough food with magnesium, vitamin D and zinc and supplementing with exercise are simple measures to avoid low testosterone levels.

In chronic cases, treatment should be performed with the permission of a physician.
