Testosterone Therapy

Testosterone (T) is the male sex hormone. It is important for normal sexual and erectile function, maintaining muscle mass, energy levels, and even mental wellbeing.

Testosterone therapy for men

T levels usually peak around your 20s and then gradually drop as you age by 1% per year on average. Unfortunately, some men might experience symptoms, once their T levels drop under a certain threshold.

Low T can lead to debilitating symptoms such as erectile dysfunction, increase in body fat, mental and cognitive problems. These symptoms can be successfully reversed by testosterone replacement therapy (TRT).

What is testosterone therapy and how does it work?

TRT is the treatment of choice for the management of low T symptoms. The therapy can effectively increase the levels of testosterone in the body back to normal.

Replacement therapy should aim at achieving blood levels of testosterone in the middle to the upper part of the normal reference range. Testosterone can be delivered successfully in the body via various routes and thus it comes in multiple forms:

  • Injections
  • Skin or mouth patches
  • Skin and nasal gels
  • Oral (Pills)
  • Implants (Pellets)

TRT is usually prescribed to men above the age of 40 since problems with T levels typically become more common. However, the therapy can be started at any age if there are medical conditions that require it and no contraindications.

TRT is currently not approved by the FDA for use in women. Nevertheless, some physicians do prescribe it in postmenopausal females, who have symptoms of low T.

Do you need TRT?

Your doctor will determine whether you need TRT by assessing your symptoms and assigning you diagnostic tests. TRT can be prescribed to people with low T levels and symptoms. The condition of having low T is called hypogonadism and can be categorized as one of two types – primary or secondary hypogonadism.

Doctor explains effects of TRT

In the case of primary hypogonadism, the testicles are unable to produce enough testosterone even under an increased stimulus by the pituitary gland. Causes of primary hypogonadism include:

  • Tumor, surgery, trauma, radiation, or infection affecting the testicles
  • Genetic conditions (such as Klinefelter’s syndrome)
  • Anatomical causes (cryptorchidism, varicocele)
  • Late-onset hypogonadism (andropause)

Secondary hypogonadism develops due to a lack of hormonal stimulus from the pituitary gland to the testicles. Thus the initial problem is in the pituitary gland but it eventually leads to testicular atrophy. Causes include:

  • Tumor, surgery, trauma, radiation, or infection affecting the pituitary gland
  • Genetic conditions (Kallmann syndrome)
  • Drugs and anabolic steroid abuse

Both men and women can suffer from low testosterone. In men the symptoms of hypogonadism include:

  • Erectile dysfunction and low libido
  • Infertility
  • Muscle loss
  • Fat gain
  • Depression and mood problems
  • Cognitive problems
  • Anemia (low red blood cells)
  • Low energy levels and fatigue
  • Loss of body and facial hair

In women, the ovaries and the adrenal glands produce small amounts of testosterone which is important for normal sexual health. Low T levels can occur after menopause, due to the declining function of the ovaries. Typical symptoms are low libido, sexual dysfunction, fatigue, mood swings, and depression.

Diagnosis

For the diagnosis, your doctor will measure the blood levels of T in the morning when normal T production should be at its highest.

Total T levels below 300 ng/dL in men indicate hypogonadism

Tests must be repeated at least once to confirm the diagnosis. If the hypogonadism is confirmed, then additional tests can categorize it as primary or secondary. They include measuring the gonadotropic hormones produced by the pituitary gland such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Low T levels lab test

According to the guidelines, high LH and FSH indicate primary hypogonadism. If they are normal or low, this is a sign of a pituitary problem and suggests secondary hypogonadism.

The proper diagnosis of low testosterone requires careful assessment of your symptoms and multiple hormonal tests to correctly identify the cause of your problems.

How to get a legal TRT

Testosterone is a prescription medication regulated by the FDA because it can be abused as a performance-enhancing drug due to its anabolic effects. Thus, obtaining legal TRT requires a prescription from a medical doctor.

Forms of testosterone treatment

The typically prescribed forms include injections, implants, and gels. Testosterone injections are the most commonly prescribed form since they are the easiest to dose and lead to the quickest rise in blood T levels. Thus, they are the most effective and reliable method to achieve the desired levels of T.

Besides, injections are considerably safer than pills because oral forms of testosterone pass through the liver first where they are metabolized and might be hepatotoxic.

Your physician will determine what is the best form of TRT and offer a legal testosterone prescription only if your medical exam and diagnostic tests indicate hypogonadism.

Who shouldn’t get TRT?

Make sure to notify your doctor if you are planning to have children in the near future. TRT can suppress the production of LH, FSH, endogenous testosterone, and spermatogenesis.

Besides, therapy may aggravate certain preexisting health conditions which can lead to serious complications. The Endocrine Society states that TRT is contraindicated in the case of:

  • problems with the lower urinary tract (due to enlarged prostate)
  • increased risk of prostate or breast cancer
  • elevated red blood cell count or thrombocytes
  • severe obstructive sleep apnea
  • congestive heart failure
  • recent (in the last 6 months) myocardial infarction or stroke

What to expect from TRT?

Patients on TRT experience improvements in sexual function, libido, erections, muscle mass, fat loss, energy levels, mood, and cognition. The therapy can also help with reversing anemia and low bone mineral density in hypogonadal men.

Unfortunately, TRT is not free of side effects. Studies report that the most common adverse reactions include elevated red blood cell count, increased urination, oily skin, acne, and reduced sperm count. Conditions such as prostate enlargement can become worse on TRT.

The evidence is still inconclusive on whether TRT increases the risk of cardiovascular diseases.

If you have any preexisting cardiovascular conditions make sure to warn your doctor

TRT’s safety and effectiveness should be carefully monitored by an experienced medical doctor for the whole duration of the treatment.

The results of TRT occur gradually over time and thus long-term therapy might be optimal to successfully reverse all symptoms of low testosterone.

How long should therapy last?

According to the scientific literature on TRT, the first benefits occur at least 3 weeks after the start of the treatment and include improved libido, mood, and quality of life.

It takes 4 weeks of TRT for cholesterol levels to improve. An increase in muscle mass, fat loss, red blood cell count, and insulin sensitivity occur after at least 3 months. Bone mineral density can also improve after 6 months.

Erectile function is also improved after 6 weeks of therapy on average

Currently, there is no recommendation on how long a TRT should last. Your doctor will estimate the length of your therapy based on its effectiveness and the occurrence of adverse reactions.

Long-term safety of TRT reports that there haven’t been any significant adverse effects due to prolonged treatment. In fact, one 11-year long trial in obese men revealed that the group on TRT had lower mortality when compared to placebo.

How much will therapy cost you?

The length of the therapy will also determine its total cost. Your TRT might cost between $100 and $1000 per month depending on the brand, dosage, and pharmaceutical form you are prescribed.

Initially, you will have extra expenses for testing and a medical exam. It will cost you around $100 to visit an experienced specialist.

Measuring your total testosterone levels costs about $50 and an extra $50 if the test includes free T. There might be additional lab tests to rule out contraindications such as PSA, hematocrit, etc. which also contribute to the total price.
