What is Testosterone Replacement Therapy (TRT) and is it right for you?
Introduction
Testosterone is a crucial hormone found in both men and women, but it plays a particularly important role in men's health. This hormone influences several bodily functions, such as muscle growth, fat burning and libido. When testosterone levels drop, various health effects can occur. This has led to the development of Testosterone Replacement Therapy (TRT), an increasingly popular treatment.
In this article, we take a closer look at what TRT is, the symptoms of low testosterone, the potential benefits and considerations of this therapy, the costs and availability in the Netherlands, and real-life experiences from users. If you’re wondering whether TRT could be right for you, you’re in the right place.

What is TRT?
Definition of TRT
Testosterone Replacement Therapy, abbreviated TRT, is a medical treatment designed to increase testosterone levels in the body. This can be done through various forms of testosterone, such as injections, gels or patches. The aim of TRT is to relieve the symptoms associated with low testosterone. Symptoms can range from fatigue and decreased libido to lack of motivation and depressive feelings.
How does TRT work?
TRT functions by adding external sources of testosterone to the body. When testosterone is introduced into the body, levels often rise rapidly, which can lead to an improvement in symptoms. However, it is important to have your blood levels checked regularly during treatment. This is necessary to ensure that testosterone levels remain at healthy levels, contributing to the effectiveness of therapy.
Different methods of TRT
There are several ways to administer TRT. The most common methods are:
- Injections: Testosterone can be administered intramuscularly, usually every two to four weeks. This method often requires a visit to the doctor or clinic for the injection.
- Gels: These are applied to the skin daily and ensure that testosterone is effectively absorbed into the blood circulation. This offers patients flexibility in their treatment routine.
- Plasters: These are attached to the skin and slowly release testosterone throughout the day. This option may appeal to people who do not want to inject.
Each method has its own advantages and disadvantages. The choice depends on the patient's preference and the doctor's recommendations. Read more On the different options for testosterone therapy.
Symptoms of testosterone deficiency
Recognising a testosterone deficiency
Testosterone deficiency can bring with it various signs and symptoms. Many men are unaware of this until they experience health problems. It is important to be alert to changes in your body and mental health. Many symptoms can be subtle at first, but often get worse as the deficiency increases.
Physical symptoms
The physical symptoms of testosterone deficiency can include fatigue, reduction in muscle mass, increase in body fat, and a decrease in bone density. Recovery after intense exercise may also take longer, negatively affecting sports performance. These symptoms can affect both physical health and overall quality of life.
Emotional effects of testosterone deficiency
Besides physical symptoms, low testosterone can also bring emotional effects. Many men experience mood swings, irritability or even depressive feelings. These emotional symptoms are often hard on those involved and can lead to problems in social relationships and at work. It is important to be aware that these effects can stem from hormonal changes. Scientific studies show that low testosterone is often associated with mental health problems.

Advantages and disadvantages of TRT
Advantages of TRT
One of the main benefits of TRT is the potential improvement in the quality of life of men struggling with symptoms of testosterone deficiency. Men who undergo TRT often report more energy, improved mood and increased libido. In addition, TRT can also help increase muscle mass and reduce body fat. These benefits are particularly appealing to many men who are ageing or struggling with a deficiency.
Disadvantages and side effects of TRT
Despite the benefits of Testosterone Replacement Therapy, there are also significant drawbacks and possible side effects. These can include acne, sleep apnoea, mood swings and an increased risk of certain health problems such as cardiovascular disease. It is essential to discuss these risks with a doctor before starting TRT so that you are well-informed about what to expect.
Cardiovascular risks of TRT
The relationship between TRT and cardiovascular disease is a subject of much debate among scientists and doctors. Some studies have suggested that TRT may increase the risk of heart problems, while others have found no significant link.
It is crucial to discuss this issue with a healthcare provider, especially if there are pre-existing heart conditions. This conversation can help make the right choices regarding TRT while safeguarding health.
Cost and availability of TRT in the Netherlands
Cost of TRT treatments
The cost of TRT can vary, depending on the treatment method chosen and the frequency of consultations. In general, the cost of testosterone injections and gels can amount to several hundred euros per month. It is wise to check with your health insurer about possible reimbursements before starting treatment, especially if you are considering long-term TRT.
Can you get TRT in the Netherlands?
Yes, TRT is available in the Netherlands, but it is important to note that it is available only on prescription. A GP or specialist must diagnose and prescribe the use of TRT. This is crucial to ensure that treatment is safe and personalised. GPs play an important role in ensuring that patients are properly managed.
Role of the GP in TRT
GPs have a vital role in prescribing TRT. They can request the necessary blood tests to determine whether testosterone deficiency really exists. Based on these results, they can suggest the most appropriate treatment. It is very important that patients do not skip this step. If you suspect you have a deficiency, don't wait too long to make a appointment.
Experiences and side effects of TRT
Patient experiences
Patient experiences with TRT vary widely. Many men are satisfied with the improvements they experience, such as more energy and a better mood. However, as with any medical treatment, it is important to recognise that some men may experience unwanted side effects. These symptoms may include irregular heartbeats or mood swings.
It is crucial that patients share their experiences and discuss any side effects with their doctor in a timely manner. This ensures better follow-up and can help adjust treatments if needed.
Side effects and concerns
As mentioned earlier, TRT can involve several side effects. You should maintain an open dialogue with your healthcare provider and raise any concerns in a timely manner. Side effects can range from mild to more severe, and your doctor can help manage them. This also creates space to adjust your treatment plan if necessary.
TRT in social media
With the rise of social media, more and more people are sharing their experiences of TRT online. This can be a valuable source of information. However, it is important to remain critical. What works healing for one person does not necessarily work for another. It is essential to always take the medical advice of professionals as a guide and do independent research before jumping to conclusions.
Conclusion
Is TRT worth it?
Whether TRT is worthwhile depends on the individual situation and health condition. For many men, it can be a life-changing treatment that helps them improve their energy levels and overall well-being. However, it is important to consider personal circumstances and health situations.
While many men report positive experiences, there are also risks involved. Statistically, about 25% of men experience side effects that may discourage them. It is crucial to carefully weigh all benefits and risks and do so in consultation with a professional. Understanding your own condition and the effects of TRT can be a difficult but important step.

Recommendations for patients
If you think you might be suffering from testosterone deficiency, make an appointment with your GP. Make sure you are well informed and ask all your questions. TRT can be a worthwhile option, but it should always be approached in a safe and responsible manner. Take care of yourself and make an informed choice.
Finally, it is essential to keep educating yourself about treatment and its possible effects. Also, continue to engage with fellow patients and share your experiences in supportive communities. The path to better health using TRT is very personal and can vary, but with the right information and support, you can make the best choice for you.
What are the risks of TRT?
TRT is generally safe with proper indication and medical supervision, but it does have potential risks. In some men, it can lead to a rise in haematocrit, which thickens the blood and can increase the risk of cardiovascular problems. Acne, fluid retention and worsening of sleep apnoea may also occur. In addition, TRT inhibits its own testosterone production, which can affect fertility. Therefore, regular blood checks and medical follow-up are essential. A doctor always assesses whether the benefits outweigh the risks based on symptoms, blood values and medical history.
Will I get a prescription for TRT?
Yes, TRT is available in the Netherlands only on prescription. This prescription is prescribed by a doctor after it has been established that there is a demonstrable testosterone deficiency based on blood tests and symptoms. This is often done through a GP, endocrinologist or specialised hormone clinic. Several measurements are usually needed, as testosterone levels can fluctuate. Only when other causes of symptoms have been ruled out and the diagnosis is clear, TRT is considered. Starting it yourself without a prescription or medical supervision is strongly discouraged because of health risks.
How long does it take for TRT to take effect?
The first effects of TRT can be noticeable within a few weeks, such as increased energy, improved mood and an increase in libido. Other effects, such as muscle building, fat loss and improved bone density, usually develop only after several months. The speed and degree of effect vary from person to person and depend on factors such as age, dosage, form of administration and lifestyle. It is important to have realistic expectations and see TRT as a long-term treatment in which regular evaluation and adjustment are part of the process.
