1. What is testosterone?

Testosterone is the principal male hormone responsible for the men-like characteristics in males. It is the chief hormone among the group of androgen hormones.

You might not know but in greek “androgen” means “man maker”. Leydig cells produce testosterone. These cells are present inside the testicles.

They produce testosterone in the presence of Luteinizing hormone (LH). Testosterone is the steroid hormone from the group of androgens. Women also produce testosterone in their ovaries.

but in a very small amount. Testosterone is also responsible for the growth of testicles and the penis. It also promotes semen production in your body.

It is also the cause of aggressive behavior and strength in men. It also helps the growth of strong and lean muscle.

During puberty and adolescence, the production of testosterone reaches its peak. After the age of 30, it starts dropping by 1% every year. So you can see the drop of almost 10% in a decade.

As testosterone has much importance in our body, we have to ensure its optimal level. We can boost testosterone levels naturally or by taking testosterone boosters.

There are also some foods that can help you boost testosterone.

2. Causes of Low testosterone in your body

The testosterone level in our body decreases when testicles decrease the production of testosterone. There are various causes of low testosterone.

Low testosterone starts with a complex chain of signals that starts in the brain. This chain is known as the hypothalamic-pituitary-gonadal axis where a very intricate physiological sequence of events is triggered.

The production of two hormones by the pituitary gland and hypothalamus decreases which results in the Leydig cells of testicles producing less testosterone.

1) Aging

Aging is one of the main causes of low testosterone levels in your body. It is very natural also.

In the scientific studies, it is proved that every man on average loses 1% of his testosterone level every year. But it is very important to understand that aging is not the only cause of testosterone deficiency.

Because testosterone deficiency is also generally found in young people.

2) Testosterone dysfunction

Lower testosterone can also occur due to the inability of testicles to produce a sufficient amount of testosterone. Testosterone dysfunction is the result of damaged testicles.

It can affect all the body and cause many physiological, chemical, and hormonal changes in the body.

3) Excess masturbation

If you are stuck in the habit of excess masturbation then it will be very difficult for you to maintain an optimal level of testosterone in your body.

According to research studies, masturbation boosts the hormone called dopamine which forces you to more masturbation.

Of course, masturbating sometimes has benefits for the body but you should always avoid excess of it. Otherwise, you will always remain testosterone deficient.

4) Low production from the pituitary gland and hypothalamus

It is often seen that when any damage occurs to the hypothalamus or pituitary gland or both can decrease the testosterone level significantly.

In such cases testicles also get affected and don’t produce testosterone in a sufficient amount.

5) Regular consumption of testosterone killing foods

If you consume some foods that tend to decrease your testosterone level (also called testosterone-killing foods) then you will see a drop in your testosterone level.

So you should avoid or limit their consumption. These foods are generally estrogenic that increase the estrogen level lowering the testosterone level.

It is always advisable to ask your doctor about the side effects of the medicines that he is prescribing to us.

It is often found in research that some medicine also can decrease the testosterone level because of their side effects.

Also remember that if you are using prescribed medicines for a prolonged period or for a nonmedical reason, then there is a possibility that they will lower your testosterone level.

It is also found in the study that some medicines increase the cortisol hormone which is considered the testosterone killer hormone.

Some blood pressure and anti-depressants also decrease the testosterone level and are also responsible for sexual dysfunction.

So it is always vital to eat a healthy diet to guarantee the body receives the nutrients it needs to produce testosterone as well as other hormones.

Congenital problems such as the decreased amount of male hormones and rare malformation syndromes can be harmful for the production of the necessary hormones.

9) Estrogen related problems

If your body has an excess amount of estrogen hormone then it will always be lacking testosterone.

If you carry excess weight on the thighs, hips, or butt area, or have the feminine breast tissue, then you have to first deal with estrogen-related problems.
