Low testosterone its cause, effect, and treatment

What is testosterone?

Testosterone is a male sex hormone that is significant for sexual and reproductive health.

The National Institutes of Health sees testosterone as the primary male hormone. Womens also produce testosterone, however at lower levels than men. 

Testosterone has a place with a class of male hormones called androgens, which are some of the time called steroids or anabolic steroids.


In men, testosterone is delivered primarily in the testicles, with a limited quantity made in the adrenal organs. The hypothalamus and pituitary organ control testosterone creation.

Testosterone levels decline with age, however for some men testosterone level drops far too early in life. As per FDA normal testosterone level is 280-1,100 ng/dl. Testosterone levels below this threshold qualify for a hypogonadism.

How it’s created?

The hypothalamus trains the pituitary organ on how much testosterone to deliver, and the pituitary organ gives the message to the testicles. 


Testosterone is engaged with the advancement of male sex organs before birth, and the improvement of optional sex qualities at adolescence.


The hormone likewise assumes a part in sex drive, sperm creation, fat distribution, red cell creation, and upkeep of muscle strength and mass, as indicated by the Mayo Clinic.

What are the cause of testosterone deficiency?


Testosterone deficiency occurs when the body is unable to make enough testosterone. It is sometimes called hypogonadism. Testosterone deficiency can significantly affect a man’s health and quality of life.

Our lifestyle choices influence our testosterone levels. Healthy choices lead to healthy testosterone levels as we age. But unhealthy ones can be destructive and lead to serious testosterone-related issues later in life.

Old Age– Testosterone levels in men decrease by 1% to 2% every after they reach 30 years.

Eating junk foods – If you’re regularly eating junk food, your body is going to suffer badly and testosterone levels will decrease. Overeating or eating processed junk foods have unhealthy levels of calories and sodium, which can lower testosterone quickly.

Not Eating enough healthy fats – Low-fat diets could be one of the reasons behind your lower testosterone levels. Always include healthy fats an integral part of your diet like walnuts, avocados, and fish to boost testosterone.

Deficiency of Vitamin D – Vitamin D deficiency is a common health problem. If you don’t get sufficient sunlight, there is correlation between this deficiency and low testosterone. So boost your vitamin D by taking supplements of Vitamin D3 or exposure to sunlight.

Lack of physical activity and exercise – A lack of physical activity is one of the most common culprits of low testosterone. Regular exercise and physical activity is the best way to increase your testosterone levels quickly. When exercise regularly, increased testosterone production allows your muscle recover quickly and grow stronger.

Abuse of supplements – While supplements can raise your T-levels, but synthetic supplements lowers your natural testosterone production. So you need to be careful while using those drugs or supplements.

Chronic stress – Chronic stress produces a hormone known as cortisol, which lowers your testosterone levels. Make sure to get required rest by your body and mind. And try to balance your work and personal life to reduce stress and manage your testosterone levels healthy.

Obesity– Obesity is one of the cause of lower testosterone levels in men. A study found that a four-inch increase in waist size lowered testosterone levels by 75%. So reducing weight should be very important for managing your testosterone levels to normal.

How Sleep deprivation lowers testosterone? 

Some people experience a paradoxical sleep deprivation which  is characterised by little or no sleep over long periods of time without problems.


People often experience heightened awareness of their surroundings when they sleep.

The timing of sleep may be more important than sleep length itself in determining testosterone levels. Sleeping in the second half  reduces testosterone more than the first half.


The first 3–4 h of sleep is critical to determine the increase in testosterone. A recent study has shown that restriction of sleep time to 4.5 h was associated with a lower morning testosterone level.  

Restriction of sleep for eight nights to 5 h a night decreased testosterone levels by 10%–15%.

Shift work

The most common form circadian rhythm disturbance occurs as a result of shift work.

Shift work has an adverse effect on testosterone levels since disturbed sleep leads to increased need for sleep and recovery, increased cortisol levels thus lowering testosterone levels.

Testosterone and sleep quality

The testosterone levels have been shown to affect sleep quality. In a study of men aged 65 years and over, those with lower testosterone levels had low sleep efficiency, increased night wakefulness.

Testosterone therapy

  • Injections. Testosterone injections can be given every 14 days. Testosterone levels can shoot up for few days after the injection and then slowly reduces, which can have adverse effect on mood and energy levels.
  • Skin patch. A patch is applied everyday in evening which releases small quantity of the testosterone hormone into the skin.
  • Gels. Topical gels is applied in the skin like arms, shoulders, or thighs. It is necessary to wash your hands and cover the area to prevent exposing testosterone hormone to others.
  • Oral therapy. Capsules are swallowed or tablets are attached to inner cheek and testosterone is then absorbed in the body.

Abdominal fat is responsible for converting testosterone into Estrogen.  

As mentioned earlier, not all exercises affect T levels in the same way. Here are some of the best exercises that can help increase testosterone.

Resistance training

Resistance exercises is a proven way to increase short- and long-term testosterone levels.

Weightlifting regularly can boost testosterone in both the short and long term. Those who lift weight have higher testosterone levels.
