What Causes Low Testosterone In Young Males


Males with low testosterone, known as hypogonadism, can be caused by various factors. This can have a lifelong effect on physical, social and sexual functioning. So, it is important to understand the causes of low T.

Genetic disorders such as Klinefelter Syndrome, Kleinfelter Syndrome (XXY) and Kleefstra Syndrome (XXXY) may lead to infertility and enlarged breasts.

Medical conditions that affect the HPG axis (responsible for the release of sex hormones) can result in hypogonadism. Examples include pituitary tumor, hyperthyroidism and chronic liver diseases. These cases require long-term management.

Medications such as ACE inhibitors, statins, antipsychotics, mood stabilizers and anxiolytics could interfere with testosterone production over long periods. If you experience low T symptoms or have been diagnosed, make sure to talk to your doctor about switching medications or alternative treatments.

Causes of Low Testosterone

Hypogonadism, also known as low testosterone, is a condition commonly found in older men. But it can affect people at any age. Symptoms include fatigue, decreased sex drive and infertility. To treat this condition, it’s important to understand what may be the cause.

Let’s look into potential causes of low testosterone in young males:

Poor Diet

Eating a poor diet and having nutrient deficiencies can have an impact on Low Testosterone in young males. The body needs essential nutrients to stay healthy. These include vitamins B2 and B6, vitamin D, zinc, magnesium, and selenium.

Eating too much refined carbs or sugar can cause weight gain and insulin resistance. This is bad for testosterone. Eating lots of processed food and drinking too much alcohol also lowers testosterone. So, young men should eat a balanced diet. This should contain lean proteins and complex carbs. This will help maintain normal testosterone levels.

Lack of Exercise

No physical activity can have a serious bad effect on testosterone production in young males. Exercise helps build and keep muscle mass, which is the main source of testosterone production in males. Without enough activity, teenagers won’t make enough testosterone to reach their highest performance or keep healthy levels of the hormone in their blood.

Studies have shown that 30 minutes of moderate physical activity every day can help young men boost testosterone levels. Examples of good exercises are running, weightlifting, swimming, and HIIT. These will help a teenager increase their muscle mass and, in turn, their testosterone levels. This can then affect strength and stamina in sports, studies, and other life areas.


Stress can decrease testosterone production in the body. It causes hormones like cortisol and ACTH to bind to receptors that prevent testosterone from being produced.

Chronic stress can also lead to low testosterone levels. Not getting enough sleep, worrying, having an illness or injury, eating a poor diet, exercising too much, not sleeping enough, and having chronic illnesses can all make cortisol levels higher and lead to decreased testosterone production. Normal life pressures are usually not seen as chronic stress.

Depression or emotional trauma can also lower testosterone due to the mental pressure they put on the body. In addition, abusing drugs like anabolic steroids can damage the endocrine system and cause low testosterone symptoms.


Medications can reduce testosterone in young males. Steroids, certain hormones, antibiotics, antifungals, heart meds, psychiatric drugs, and chemo are all examples.

Recreational drug use can also reduce testosterone. Cocaine and amphetamines have been linked to decreased hormone production. Prolonged use can cause health issues due to hypogonadism or extreme changes in hormone production.

Hormonal Imbalance

Low testosterone could be due to a disruption in the hormones of the hypothalamic-pituitary-testicular (HPT) axis. This axis is a system of glands: hypothalamus, pituitary and testicles. The hormones involved are: LH, FSH and Estrogen.

A disruption in the HPT axis can cause low sex drive, erectile dysfunction, fatigue, low muscle mass, irritability and depression. It is important to check for possible underlying conditions, such as:

  • obesity
  • hyperthyroidism
  • hypothyroidism
  • PCOS
  • liver disease
  • kidney failure

These can all impact hormone levels. A doctor should be consulted to investigate any hormonal imbalance. Depending on the underlying causes, medication(s) and/or lifestyle changes may be prescribed. These lifestyle changes may include increased physical activity or dietary changes.

Certain Medical Conditions

Certain medical conditions can cause low testosterone levels. These include diseases affecting the hypothalamus, pituitary, or testes. Diabetes, chronic kidney disease, and obesity could also lead to secondary hypogonadism.

Low testosterone can also be due to genetic mutations in the testes, or Klinefelter’s Syndrome. Medications like barbiturates, opiates, anti-seizure drugs, alcohol use disorders, benzodiazepines, corticosteroids, HIV protease inhibitors, and antipsychotics can also cause low testosterone.


Low testosterone in young men, known as hypogonadism, is a condition which causes a drop in testosterone production. This can lead to reduced libido, enlarged male breast tissue (gynecomastia), infertility and more. Knowing the cause of this production drop can help to identify treatment options and management methods.

A thorough medical exam is needed to diagnose the cause. This includes a medical history, physical exam, blood tests, ultrasound or MRI imaging, and semen analysis if needed. The doctor looks for signs that might point to medical conditions or lifestyle choices causing the low testosterone. These may include:

  • Medications: Steroids and other hormones used to treat cancer may affect testosterone production.
  • Alcohol Use: Over time, alcohol use has been linked with lowered testosterone levels by decreasing body circulation.
  • Tobacco Use: Smoking cigarettes has been linked to lowered testosterone due to its effect on the liver.
  • Obesity: Too much weight can reduce energy production, which affects anabolic hormones like testosterone.
  • Health Conditions: Diseases such as kidney failure, chronic liver disease or testicular diseases can reduce male sex hormones, causing reduced muscle growth and libido.


Low testosterone in young males needs treatment. This may involve life changes, medicine, testosterone replacement, or a combo of these. Doctors may recommend vitamins and supplements too. Let’s look at the treatments more closely:

  • Life changes
  • Medicine
  • Testosterone replacement
  • Combination of the above
  • Vitamins and supplements

Lifestyle Changes

For managing low testosterone symptoms, lifestyle changes are very important. Diet, exercise, and reducing stress can make a big difference.

Regarding diet, fresh fruits and vegetables must be eaten in balance. Avoid trans fats, saturated fats, and cholesterol which interfere with hormone production. Steer clear of red meat, dairy products and whole grains which are high in calories and low in beneficial dietary fiber.

Exercise should be done regularly to keep testosterone levels up. Even moderate activities like walking for 30 minutes a day can help. High-intensity activities such as weight lifting or interval training boost testosterone further by increasing luteinizing hormone secretion from the pituitary gland.

To reduce stress, relaxation techniques like yoga and meditation should be used and activities that promote mental well-being should be done, such as listening to music or spending time outdoors.

Hormone Replacement Therapy

Hormone Replacement Therapy (HRT) is a popular treatment for low testosterone levels in young males. It involves taking synthetic hormones, similar to the hormones produced by the male body. Benefits of this treatment include: improved energy and libido, increased muscle mass and strength, better psychological well-being and stronger bones. It can also boost sperm production, enhance fertility and reduce signs of aging.

HRT may be administered through an injection, topical gel or patch, pill or skin patch therapy. The choice of method depends on the patient’s preferences, desired outcome, and convenience. HRT requires frequent lab monitoring to avoid overlap in effects and adverse reactions with other drugs or supplements.

It’s important to note that long-term use of HRT may increase the risk of cardiovascular disease or cancer. Therefore, it isn’t usually recommended as the first line treatment for young males with low testosterone levels. If you pursue HRT, it should be done under close medical supervision for optimal results and to avoid any serious risks.


To sum up, there are many causes of low testosterone in young males. Exercising, reducing stress, and avoiding drugs can help increase testosterone levels. It’s also crucial to visit a doctor if you’re worried about your hormones. Medications are available to help manage symptoms of low testosterone, regardless of the underlying cause.

Taking time to understand the causes and treatment options is important for young males. It will help bring hormones back into balance and provide peace of mind.
