Testosterone is a vital hormone that both men and women produce, though men typically have higher levels. For many years, our understanding of testosterone has been evolving, with more attention given to when it’s appropriate to prescribe it and for whom. Today, more people are turning to testosterone treatments, but it’s important to know when it’s necessary and what the hormone actually does for the body.
What Does Testosterone Do?
Testosterone is often referred to as the "vitality hormone" because of its significant role in maintaining energy, mood, and overall health. In men, it’s essential during puberty, helping to develop muscle mass, genitals, hair growth patterns, and sexual drive. It also has a major influence on physical strength, bone density, and red blood cell production. During youth, testosterone makes men feel invincible: stronger, faster, and more energetic.
As we age, testosterone levels begin to decline, typically around the age of 30, and continue to decrease gradually. This decline leads to symptoms such as brain fog, fatigue, reduced motivation, and a decrease in sexual drive. Whilst these are natural signs of aging, in some cases low testosterone can be a significant factor.
Why Testosterone Declines
For most men, testosterone peaks during adolescence and young adulthood; after that, levels begin to taper off, and by the time men reach their 50s, they often experience symptoms of lower testosterone. However, the normal range of testosterone has shifted over the years; research shows that testosterone levels are now approximately 15–20% lower than they were in previous generations. The reasons for this decline include changes in lifestyle, with more sedentary work environments, poor sleep habits, stress, and rising obesity rates, all of which contribute to lower testosterone levels.
Symptoms of Low Testosterone
The symptoms of low testosterone can be wide-ranging. While sexual dysfunction is commonly associated with it, many people experiencing low testosterone report issues like brain fog, fatigue, and a lack of drive. Interestingly, these symptoms are not exclusive to testosterone deficiencies and can also be caused by other health conditions like sleep apnea, stress, or even poor lifestyle habits.
This is why it’s crucial to take a holistic approach when diagnosing low testosterone. A simple blood test alone can’t determine the need for testosterone replacement therapy (TRT). It is essential to consider other factors such as blood work, lifestyle habits, and physical assessments before deciding on treatment.
When to Consider Testosterone Replacement Therapy
Testosterone replacement therapy (TRT) is not a one-size-fits-all solution. For some, it can be life-changing, restoring energy, drive, and overall vitality. However, it’s not something that should be prescribed lightly. TRT can be a long-term commitment, and before jumping to this treatment, we need to rule out other potential causes of symptoms, such as sleep apnea, stress, or endocrine disruptors.
A thorough assessment is essential. In our practice, we evaluate a person’s symptoms, perform extensive blood work, and review questionnaires before making any decisions about testosterone therapy. It’s important to note that a drop in testosterone levels as we age is normal, but there are cases where therapy can make a significant difference.
The Pros and Cons of Testosterone Replacement Therapy
The Benefits of TRT
Testosterone replacement therapy can offer noticeable improvements, especially for individuals experiencing symptoms related to low testosterone. The benefits may include:
Increased energy and drive
Enhanced muscle mass and strength
Decreased body fat
Improved overall vitality
For many men, TRT provides a significant boost in quality of life, helping them regain the energy and vigor they had in their younger years. However, it's important to weigh these benefits against the potential downsides.
The Risks of TRT
One of the biggest risks associated with TRT, especially for younger individuals, is the potential to impair fertility. Testosterone therapy can reduce sperm production, leading to sterility, which is why it’s critical to consider whether you are done with having children before pursuing treatment.
While TRT can be beneficial for men in their 40s and 50s who have completed their families, younger men must be particularly cautious. Starting testosterone therapy prematurely without fully understanding the implications could lead to long-term consequences.
What to Consider Before Starting TRT
Before jumping into testosterone replacement therapy, there are several factors that need to be addressed. One of the most important aspects of maintaining healthy testosterone levels is ensuring good lifestyle habits, which can often help avoid the need for TRT altogether.
1. Sleep: Your Superpower
We’ve mentioned this before, but sleep is essential for overall health, including maintaining healthy testosterone levels. Poor sleep patterns can significantly impact hormone production, so ensuring you get enough rest is key.
2. Exercise: Heavy Lifting Matters
Engaging in physical activities that require heavy lifting is another essential factor in boosting testosterone levels. While steady-state cardio is beneficial for overall fitness, high-intensity interval training (HIIT) or weightlifting can help stimulate testosterone production more effectively.
3. Avoid Excessive Alcohol Consumption
In many cultures, drinking alcohol is a common social activity, but it can have a significant impact on testosterone production. Even moderate drinking, such as half a bottle of wine a night, can suppress testosterone levels and interfere with sleep, further exacerbating hormone imbalances.
4. Exclude Other Health Conditions
Before considering TRT, it's important to rule out other potential causes of low testosterone symptoms, such as sleep apnea or lifestyle-related factors. A thorough screening process, including sleep tests and lifestyle assessments, is necessary.
What Happens After Excluding Other Factors?
Once lifestyle factors are addressed, and other conditions like sleep apnea have been ruled out, it’s time to consider treatment options. For men aged 47–52 who are done with having children and looking to restore their drive and muscle mass, testosterone replacement therapy might be appropriate.
The Standard Treatment: Depot Injections
Currently, the most common method for testosterone replacement in South Africa is depot injections, where testosterone is injected every few months. However, this method has its drawbacks. Testosterone follows a natural daily cycle, with levels peaking in the morning and dropping in the afternoon and evening. With depot injections, there’s a risk of overshooting the optimal level, causing high testosterone levels followed by periods of deficiency, making it difficult to maintain stable hormone levels.
While depot injections may seem convenient, they are not ideal because of the fluctuating testosterone levels. Additionally, the discomfort and potential for side effects, such as increased hematocrit or shutting down the body’s natural testosterone production, make it less favorable in the long run.
To overcome this, some opt for subcutaneous injections, which are smaller, more frequent doses. These injections are given either under the skin or into the muscle, typically on a weekly basis. While more consistent, daily injections would offer the most natural approach to testosterone replacement, they are not practical for most people due to the inconvenience of daily self-injections.
The Cream and Gel Alternatives: Bioidentical and Convenient
For those who prefer not to inject themselves, creams and gels are a convenient and effective alternative. These bioidentical options are typically applied to the skin, where they are absorbed into the bloodstream. The advantage of creams and gels is their ease of use and ability to be adjusted for personal needs.
One significant benefit of using creams is that they mimic the body's natural testosterone rhythm. Applied in the morning, testosterone levels peak within 2-3 hours, then gradually decline over the next 8-16 hours, mimicking the body's natural cycle. This method is less likely to lead to overshooting testosterone levels, which can sometimes result in unwanted side effects, such as increased hematocrit levels.
However, there are a few considerations. First, the absorption of the cream can vary from person to person, which is why regular testing is necessary to ensure the correct dose. Also, whilst creams are relatively simple to apply, precautions need to be taken to avoid transferring the testosterone to others. Care should be taken to avoid contact with others (especially children) after applying the cream, as it can transfer through skin-to-skin contact.
Managing Side Effects: Balancing Hormones Safely
While testosterone replacement therapy can significantly improve quality of life by restoring energy levels, improving muscle mass, and enhancing mood, it's essential to approach it cautiously. Overuse or misuse of testosterone, especially at high doses, can lead to adverse effects like gynecomastia as well as an imbalance in estrogen levels. This is often seen in bodybuilding circles, where high doses are used to push beyond normal physiological levels.
It's crucial to monitor testosterone and estrogen levels regularly, particularly for younger individuals who may still be interested in fertility. For younger men, HCG (human chorionic gonadotropin) or clomiphene citrate can be used alongside testosterone to help maintain fertility. These medications mimic the body's natural signals to stimulate testosterone production while minimizing the risk of fertility loss.
For those over the age of 47, testosterone therapy is often more about restoring balance to natural levels. However, even in this age group, it’s important to avoid the temptation of overdoing it. Proper testing, monitoring, and lifestyle changes are essential for maximizing the benefits of testosterone therapy.
The Importance of Consultation and Regular Monitoring
One of the most critical aspects of testosterone replacement therapy is ensuring that the treatment plan is tailored to the individual. As a patient, you must undergo thorough testing to understand where your testosterone levels are and what other factors may be contributing to your symptoms. This ensures that your therapy is appropriate for your body and goals.
A proper consultation with a healthcare professional is essential to avoid the common pitfall of self-administering testosterone, often seen in the gym or from unregulated sources. Misusing testosterone, particularly through unknown or unsupervised methods, can lead to serious health risks, including liver damage, cardiovascular events, and hormonal imbalances.
The Role of Lifestyle in Maximizing TRT
It’s essential to remember that testosterone therapy isn’t a "miracle cure." To see the full benefits, lifestyle changes are necessary. Regular exercise, especially resistance training, is crucial for building muscle mass and increasing strength. Diet, stress management, and sleep quality also play significant roles in optimizing hormone levels and overall health.
While testosterone replacement therapy can help restore normal levels and improve quality of life, it should be part of a comprehensive plan that includes healthy lifestyle habits. Without these changes, the benefits of testosterone therapy may not be fully realized.
As with any treatment, it’s essential to start slowly and carefully monitor the effects. When considering testosterone replacement, make sure you are working with a knowledgeable healthcare provider who understands the risks and benefits of the therapy. This personalized approach ensures you avoid side effects and achieve the desired results without compromising your health.
In conclusion:
Testosterone replacement therapy can be a powerful tool for men looking to regain energy, strength, and vitality. But like any treatment, it’s important to take a cautious and informed approach. Whether you choose injections, creams, or gels, be sure to work closely with a healthcare provider who can guide you through the process, ensuring you’re doing what’s best for your body.
By staying within the natural range of testosterone levels, monitoring progress regularly, and making necessary lifestyle adjustments, TRT can help you feel better, look better, and age more gracefully. Just remember, always prioritize your health and safety, and seek professional guidance when necessary.
