What is testosterone?
Testosterone is a sex hormone produced primarily by the gonads (testicles in men, ovaries in women), although the adrenal glands also produce some amounts. It is classified as an androgen, which is the group of hormones involved in the development of male sexual characteristics.
This hormone performs really important functions in the human body, especially in men. However, like all other hormones, it can have negative effects if not controlled. Precisely for this reason, it is essential to keep it within normal parameters.
Testosterone Production in Men
In men, testosterone is predominantly produced in the testes via Leydig cells. This process is regulated by the hypothalamus and pituitary gland, which adjust production through the release of testosterone. LH hormone or luteinizing. Testosterone levels typically peak during adolescence and remain relatively stable through adulthood. As we age, it is natural for production to begin to decline.

What is testosterone used for in men?
The main functions of testosterone are:
- Before birth, during gestation, testosterone is responsible for generating the sex differentiation in the baby, since this hormone is what causes the formation of the male reproductive system.
- During male adolescence, testosterone develops secondary sexual characteristics such as pubic and facial hair, the change from a high-pitched voice to a deeper one, and of course the development and proper functioning of the male reproductive organ.
- Testosterone is responsible for maintenance and increased libido, thus acting in provoking and maintaining erections.
- Another important responsibility of testosterone is that of formation and maturation of the sperm, and in this way the development of semen of adequate quality to achieve fertilization.
- Testosterone has many more functions besides sexual ones. Participates in the formation of bones and their maintenance Over the years, avoiding fractures and the appearance of diseases such as osteoporosis. In addition, it collaborates with the growth of the prostate gland, accelerates the metabolism of man, and reduces the level of bad cholesterol in the blood.

What increases testosterone?
What lowers testosterone?
There are several factors that can contribute to decreased testosterone levels in the body. Here are some of the main reasons why testosterone can decrease:
1. Aging
Aging is one of the most common causes of declining testosterone. Testosterone levels tend to gradually decline with age, starting around age 30 and continuing throughout life.
2. Chronic Stress
Chronic stress causes an increase in the production of cortisol, the stress hormone. High levels of cortisol can suppress testosterone production. Stress can also affect sleep quality, which in turn can contribute to decreased testosterone.
3. Poor nutrition
A diet low in essential nutrients, such as zinc, vitamin D, and healthy fats, can negatively affect testosterone production. A diet high in refined sugars, processed foods, and trans fats can also contribute to hormone decline.
4. Sedentary lifestyle
Lack of regular physical activity, especially strength and endurance exercises, can lead to a decrease in testosterone. Exercise, on the other hand, can help maintain healthy levels of this hormone.
5. Obesity
Excess body fat, especially in the abdominal area, can convert testosterone into estrogen, decreasing testosterone levels. Obesity can also lead to chronic inflammation, which can affect testosterone production.
6. Excessive alcohol consumption
Excessive alcohol consumption can reduce testosterone production by damaging the cells in the testicles responsible for synthesizing this hormone. It can also affect the liver, which plays a role in hormone metabolism.
7. Medications and Medical Treatments
Some medications that cause impotence, such as anabolic steroids, antidepressants, blood pressure medications, and cancer treatments, can reduce testosterone levels. Medical treatments such as chemotherapy or radiation therapy can also affect hormone production.
8. Health Disorders
Some diseases and disorders can reduce testosterone. Examples include type 2 diabetes, liver disease, kidney problems, hypothyroidism, and certain autoimmune diseases. Injuries to the testicles or surgeries related to the reproductive system can also be causes.
9. Sleep problems
Poor or insufficient sleep can reduce testosterone production. Lack of sleep disrupts overall hormonal balance and can lead to decreased energy, low libido and other factors associated with testosterone.
10. Other Factors
Fatherhood?
Yes, various studies have shown that fatherhood can cause a natural decline in male testosterone levels. Research such as that of Northwestern University (2011) and psychologist Brenda Volling (2015) observed that, after the birth of a child, men experience a hormonal drop that is associated with increased empathy and decreased aggression, thus facilitating bonding and parenting.
Although this decrease can be biologically positive in the short term, in some cases it can persist over time and cause symptoms such as fatigue, low sex drive, or loss of muscle mass. Therefore, if you notice persistent changes in your well-being after becoming a parent, it's advisable to undergo a medical evaluation to assess your hormone levels and consider possible treatments.
At what age does testosterone decrease?
From the age of 40, there is already around 10% of partial testosterone deficiency in men, and from the age of 45, there begins a gradual decrease of 1% per year. Thus, there would be (according to the Baltimore study) a loss of testosterone of 20% at 60 years of age, 30% at 70 years of age and 50% at 80 years of age.
Therefore, although we find ourselves with free testosterone deficiency At earlier ages, it is advisable to request PSA as well as routine. In addition, as a marker of prostate cancer from the age of 45, we should also assess the free testosteroneIn the case of men, it would be advisable to visit their doctor at least once a year, requesting an analysis with these parameters.
Why should I monitor my hormone levels?
It should be noted that one of the most frequent manifestations is the erectile dysfunction. This may be a sentinel symptom of other more serious pathologies, since the origin of this dysfunction may be:
- vascular origin (40%)
- metabolic syndrome (20%)
It is also currently known that Low testosterone increases the risk of prostate cancer.
It should be noted that in 40% of cases, nitric oxide stimulating drugs, which facilitate an erection, known as drugs for erectile dysfunction (such as Viagra, Levitra or Cialis) are not effective if there is no level of enough testosterone, because this hormone stimulates the synthesis of nitric oxide, increasing its synthesis, through an enzyme, said apart, sexual desire or libido will be diminished or absent.
What does hormonal decline depend on?
Esta drop in testosterone levels, it will depend on whether total testosterone or free testosterone is estimated, the figure in the general population would range from 5% to 18%, according to statistics.
As we know, 60% of total testosterone is bound to a globulin and 40% to an albumin, and only 2% is free, which is the truly active form.
Many patients are taking multiple medications with antidepressants, which only aggravate the problem, based on the fact that 20% of erectile disorders are of psychogenic origin, without taking into account that there may be an underlying hormonal deficiency. You can check your testosterone levels approximately with this online testosterone test free.
Testosterone Levels: Normal and Abnormal
Testosterone, like other hormones, has a range that is considered normal in the body. These levels fluctuate according to various factors, including age and sex. Understanding what are normal and abnormal levels is essential to detect possible hormonal imbalances.
Normal Testosterone Levels
Testosterone levels are usually measured in nanograms per deciliter (ng/dL). In men, normal levels are typically between 300 and 1,000 ng/dL. For women, this range is considerably lower, ranging from 15 to 70 ng/dL. These values may vary slightly depending on the laboratory and the techniques used for measurement.
Low Testosterone Levels
Low testosterone levels can affect both men and women, causing a range of symptoms and health problems.

In men, from the age of 30, Testosterone levels are decreasing gradually. This affects men's sexual life and health. Therefore, it is very important to make a Testosterone level monitoring by consulting a specialist doctor. Bad practice can lead to different risks and negative consequences for testosterone.
What is the best vitamin to increase testosterone?

Low Testosterone in Older Adults: Does It Also Have a Solution?
Yes. Research led by LA BioMed in collaboration with the National Institute on Aging (USA) demonstrated that testosterone replacement therapy in men over 65 years of age with hypogonadism significantly improves the Bone density y corrects anemia.
The studies, known as TTrials, also revealed an increase in the bone strength and at the levels of hemoglobin, even in cases with iron deficiency anemia. Although no improvements in memory or cognitive function were observed, the findings reinforce the clinical benefits of hormone treatment in older patients with low testosterone.
Interpretation of results
Once the test results are in, it is crucial to know how to interpret them. Normal testosterone levels can vary considerably, but the following values are generally considered:
- Men: 300 to 1000 ng/dL (nanograms per deciliter)
- Women: 15 to 70 ng/dL
When results show low testosterone levels, a variety of causes may be considered, including aging, medical conditions, or medications. Conversely, elevated levels may imply other health problems, such as chronic diseases or tumors in hormonal glands.
It is important that the interpretation of results is performed by a qualified medical professional, who can consider other relevant factors, such as physical symptoms, medical history, and other test results, to provide a comprehensive diagnosis. This evaluation is essential to determine appropriate treatment, if necessary, and to help manage potential risks associated with abnormal testosterone levels.
Conclusion
In conclusion, testosterone plays multiple vital roles in the male body, from sexual development during pregnancy to maintaining libido, muscle mass, and bone health in adulthood. Maintaining adequate testosterone levels is crucial for men's overall health and emotional well-being. Through dietary changes, regular exercise, and a balanced lifestyle, it is possible to naturally promote testosterone production, thus ensuring optimal body function and a better quality of life.
