What Does Testosterone Replacement Therapy Do To A Man?

Posted on July 13, 2023 by Sally-Anne Turner

Testosterone is a hormone that plays a crucial role in the development and maintenance of male characteristics, including muscle mass, bone density, and sexual organs. However, as men age, their testosterone levels naturally decline, leading to a variety of health issues. Testosterone replacement therapy (TRT) is a medical treatment that aims to increase testosterone levels in men with low levels of the hormone. This decline typically begins around the age of 30, with testosterone levels dropping by approximately 1-2% each year thereafter. For some men, this gradual decline can result in testosterone levels falling below the normal range, a condition known as hypogonadism or low testosterone (low T).

In this blog post, we will explore the benefits and risks of testosterone replacement therapy as we discuss what taking the treatment does to a man. Low testosterone is a growing issue for men and is widely left untreated. This can result in men suffering unnecessarily with physical, emotional, mental, and sexual symptoms such as low energy levels, lack of focus, low libido, reduced muscle mass and weight gain, and more. Many men struggle in silence, unaware that their symptoms may be related to declining testosterone levels, or feel embarrassed to seek help for what they perceive as a natural part of ageing. However, when testosterone levels drop significantly below normal ranges, the impact on quality of life can be substantial, affecting everything from work performance to personal relationships and overall wellbeing.

Understanding testosterone replacement therapy is essential for any man experiencing symptoms of low testosterone. The treatment has evolved significantly over recent years, with improved delivery methods, better monitoring protocols, and a growing body of research supporting its safe and effective use when properly administered. At Bodyline Medical Wellness Clinics, we've supported thousands of men through their testosterone replacement therapy journey, helping them regain vitality, confidence, and overall health through personalised treatment plans tailored to their individual needs and circumstances.

What is Testosterone Replacement Therapy?

Testosterone replacement therapy involves the administration of testosterone through creams at Bodyline Medical Wellness Clinics to men with low testosterone levels as a form of hormone replacement therapy. The treatment aims to restore testosterone levels to normal levels and improve the symptoms associated with low testosterone levels. TRT is not a one-size-fits-all solution; rather, it requires careful assessment, individualised dosing, and ongoing monitoring to ensure optimal results whilst minimising potential risks.

At Bodyline, we prescribe hormone replacement therapy, including testosterone, dehydroepiandrosterone (DHEA), vitamin D, and vitamin B12. Personalised prescriptions of TRT can be easily adjusted based on changing symptoms and future blood test results. We also offer advice on lifestyle, exercise, and diet, as well as recommend wellness-enhancing vitamins and supplements. Our approach recognises that testosterone replacement therapy works best when combined with comprehensive lifestyle modifications, proper nutrition, regular exercise, and adequate sleep. This holistic approach ensures that men achieve the best possible outcomes from their treatment.

The process of starting testosterone replacement therapy at Bodyline begins with a thorough assessment of your symptoms, medical history, and current health status. We conduct comprehensive blood tests to measure not only your testosterone levels but also other important markers such as prostate-specific antigen (PSA), full blood count, liver function, and cholesterol levels. This baseline assessment is crucial for determining whether TRT is appropriate and safe for you, and it provides a reference point against which we can measure your progress throughout treatment.

Our testosterone replacement therapy uses transdermal creams, which offer several advantages over other delivery methods. Creams allow for steady absorption of testosterone through the skin, providing more consistent blood levels throughout the day compared to injections, which can cause peaks and troughs in testosterone levels. This steady delivery often results in a more stable mood and energy level, with fewer fluctuations in symptoms. The creams are applied daily, typically to areas of thin skin such as the inner forearms or shoulders, where absorption is optimal. This method also allows for easy dose adjustment if needed, providing flexibility in your treatment plan.

Before beginning testosterone replacement therapy, it's essential to understand that TRT is a long-term commitment to your health. Whilst some men may notice improvements in symptoms within a few weeks, the full benefits of treatment typically become apparent after three to six months of consistent use. Once you start TRT, your body's natural testosterone production may decrease further, which means that stopping treatment abruptly can lead to a temporary worsening of symptoms. This is why it's crucial to work with experienced healthcare professionals like the team at Bodyline, who can guide you through the entire treatment process and help you make informed decisions about your health.

What are the Benefits of Testosterone Replacement Therapy?

Testosterone replacement therapy can provide a range of benefits to men with low testosterone levels. Some of the benefits of TRT include improvements in physical health, mental wellbeing, sexual function, and overall quality of life. These benefits can be transformative for men who have been struggling with the debilitating symptoms of low testosterone, often for years without realising the underlying cause. Understanding what testosterone replacement therapy can do for you helps set realistic expectations and motivates commitment to the treatment plan.

1. Increased Muscle Mass and Strength

Testosterone plays a crucial role in the development and maintenance of muscle mass and strength. Men with low testosterone levels may experience a decrease in muscle mass and strength, leading to weakness and fatigue. TRT can help increase muscle mass and strength, leading to more energy and vitality. This anabolic effect of testosterone occurs because the hormone stimulates protein synthesis in muscle tissue, promoting muscle growth and repair. Many men on TRT report that they find it easier to build and maintain muscle mass through resistance training, even if they've struggled with this in the past.

The increase in muscle mass isn't just about aesthetics or athletic performance, although these can certainly improve. Greater muscle mass has important metabolic benefits, including improved insulin sensitivity, better blood sugar control, and increased resting metabolic rate, which can help with weight management. Muscle tissue is metabolically active, meaning it burns calories even at rest, so having more muscle mass can make it easier to maintain a healthy weight. Additionally, stronger muscles improve functional capacity for daily activities, reducing the risk of falls and injuries, which becomes increasingly important as men age.

Men typically begin to notice improvements in muscle mass and strength after approximately three to six months of consistent testosterone replacement therapy, particularly when combined with regular resistance training. At Bodyline, we provide guidance on appropriate exercise programmes to maximise the muscle-building benefits of TRT, ensuring that you're training safely and effectively. We recommend incorporating both resistance training and cardiovascular exercise into your routine for optimal health benefits.

1. Improved Bone Density

Testosterone is essential for bone health, and low testosterone levels can lead to a decrease in bone density and an increased risk of fractures. TRT can help improve bone density, reducing the risk of fractures and osteoporosis. Whilst osteoporosis is often thought of as a condition affecting primarily women, men with low testosterone are also at significant risk of developing this debilitating bone disease. Testosterone stimulates bone-forming cells called osteoblasts, which are responsible for building new bone tissue and maintaining bone strength.

The improvement in bone density from testosterone replacement therapy is particularly important for older men, who face an increased risk of falls and fractures. Hip fractures in elderly men are associated with significant morbidity and mortality, so maintaining bone strength through TRT can have life-saving implications. Studies have shown that men with higher testosterone levels have greater bone mineral density and are less likely to experience osteoporotic fractures. By restoring testosterone to normal levels, TRT helps protect against age-related bone loss and maintains skeletal integrity.

The bone-strengthening effects of testosterone replacement therapy typically take longer to manifest than some other benefits, often requiring 12 to 24 months of treatment before significant improvements in bone density can be measured. This is because bone remodelling is a slow process, with old bone being gradually replaced by new, stronger bone tissue. Regular monitoring through bone density scans may be recommended for men at higher risk of osteoporosis to track the effectiveness of treatment over time.

1. Increased Libido and Sexual Function

Testosterone is responsible for male sexual function, including libido and erectile function. Men with low testosterone levels may experience a decrease in libido and sexual function, leading to reduced sexual satisfaction. TRT can help improve libido and sexual function, leading to an increased sense of well-being and satisfaction. For many men, the decline in sexual function associated with low testosterone is one of the most distressing symptoms, affecting not only their own quality of life but also their intimate relationships.

The impact of testosterone on sexual function is multifaceted. Testosterone influences sexual desire and arousal, the ability to achieve and maintain erections, and the quality of orgasms. When testosterone levels are low, men may experience reduced interest in sex, difficulty achieving erections, decreased sensitivity, and reduced sexual satisfaction. Testosterone replacement therapy can address all these aspects of sexual function, often resulting in significant improvements in sexual health and intimate relationships.

Many men notice improvements in libido within the first few weeks of starting testosterone replacement therapy, although improvements in erectile function may take longer, typically three to six months. It's important to note that whilst TRT can significantly improve sexual function in men with low testosterone, it's not a treatment for erectile dysfunction caused by other factors such as vascular disease, diabetes, or psychological issues. At Bodyline, we take a comprehensive approach to men's sexual health, addressing all potential contributing factors to ensure the best possible outcomes.

The improvement in sexual function from TRT extends beyond the physical aspects. Many men report feeling more confident, more masculine, and more satisfied with their intimate relationships. This psychological boost can have far-reaching effects on overall wellbeing and quality of life. Partners often report positive changes as well, noting improvements in intimacy and relationship satisfaction. If you're experiencing sexual dysfunction, book a consultation at Bodyline Clinic to discuss whether low testosterone might be the underlying cause.

1. Improved Mood and Cognitive Function

Testosterone plays a role in mood regulation and cognitive function. Men with low testosterone levels may experience mood swings, depression, and cognitive decline. TRT can help improve mood and cognitive function, leading to a better quality of life. The connection between testosterone and mental health is increasingly recognised by healthcare professionals, with research showing that low testosterone levels are associated with increased rates of depression, anxiety, irritability, and reduced overall sense of wellbeing.

The mechanisms by which testosterone influences mood and cognition are complex and not fully understood, but testosterone receptors are found throughout the brain, including in areas responsible for mood regulation, memory, and executive function. Testosterone appears to influence the production and function of neurotransmitters such as serotonin and dopamine, which play crucial roles in mood regulation. Low testosterone levels can disrupt these neurotransmitter systems, contributing to symptoms of depression and anxiety.

Men on testosterone replacement therapy often report improvements in mood, including reduced irritability, less anxiety, better stress tolerance, and an enhanced overall sense of wellbeing. Many describe feeling more like their "old selves" again, with improved motivation, confidence, and enjoyment of life. Cognitive benefits can include better concentration, improved memory, clearer thinking, and enhanced mental sharpness. These improvements typically become noticeable within a few weeks to a few months of starting TRT.

It's important to note that whilst testosterone replacement therapy can significantly improve mood in men with low testosterone, it's not a substitute for appropriate treatment of clinical depression or other mental health conditions. At Bodyline, we take a holistic approach to men's health, recognising that mental wellbeing is influenced by multiple factors including hormones, lifestyle, stress levels, and underlying psychological conditions. If you're experiencing symptoms of depression or anxiety alongside low testosterone, we can provide appropriate referrals to mental health professionals as needed.

1. Increased Energy Levels

Men with low testosterone levels may experience fatigue and a lack of energy. TRT can help increase energy levels, leading to a more active and productive lifestyle. This fatigue associated with low testosterone is often described as overwhelming and persistent, not the kind of tiredness that improves with a good night's sleep. Men report feeling exhausted even after adequate rest, lacking the motivation and energy to engage in activities they once enjoyed, and struggling to get through the day without feeling drained.

The energy-boosting effects of testosterone replacement therapy can be profound and life-changing. Many men report feeling more vital, more motivated, and more capable of tackling daily challenges. This increased energy isn't just about physical stamina; it also includes mental energy and motivation. Men often find they're more productive at work, more engaged with family and friends, and more willing to pursue hobbies and interests. The improvement in energy levels typically begins within a few weeks of starting TRT and continues to improve over the first few months of treatment.

The mechanism by which testosterone increases energy is multifaceted. Testosterone influences red blood cell production, which improves oxygen delivery to tissues throughout the body. It also affects mitochondrial function in cells, enhancing cellular energy production. Additionally, the improvements in mood, sleep quality, and overall health that often accompany TRT contribute to increased energy and vitality. Many men find that the boost in energy from testosterone replacement therapy creates a positive cycle, where increased energy leads to more physical activity, which further improves health and wellbeing.

What are the Risks of Testosterone Replacement Therapy?

Although testosterone replacement therapy can provide numerous benefits, it is not without risks. Some of the risks associated with TRT include potential cardiovascular effects, prostate concerns, skin reactions, and sleep disturbances. Understanding these risks is essential for making an informed decision about whether TRT is right for you. At Bodyline Medical Wellness Clinics, we believe in transparent communication about both the benefits and risks of treatment, ensuring that every patient can make decisions based on complete information.

It's important to emphasise that many of the risks associated with testosterone replacement therapy can be minimised through proper screening, appropriate dosing, and regular monitoring. This is why working with experienced healthcare professionals who specialise in men's health and hormone replacement therapy is crucial. At Bodyline, we conduct thorough pre-treatment assessments to identify any contraindications or risk factors, and we monitor our patients closely throughout treatment to detect and address any potential issues early.

Increased Risk of Blood Clots

TRT can increase the risk of blood clots, especially in men with a history of blood clots or other cardiovascular conditions. Testosterone stimulates the production of red blood cells, a process called erythrocytosis. Whilst a moderate increase in red blood cell count can be beneficial, improving oxygen delivery to tissues, excessive increases can make the blood thicker and more prone to clotting. This increased blood viscosity can raise the risk of deep vein thrombosis, pulmonary embolism, and potentially stroke.

The risk of blood clots is one reason why regular blood monitoring is essential during testosterone replacement therapy. At Bodyline, we check your full blood count regularly, typically every three to six months, to monitor your haematocrit and haemoglobin levels. If these levels become elevated, we can adjust your testosterone dose or, in some cases, recommend therapeutic phlebotomy (blood donation) to reduce red blood cell count. Men with a personal or family history of blood clots, cardiovascular disease, or other clotting disorders require particularly careful monitoring and may not be suitable candidates for TRT.

To minimise the risk of blood clots whilst on testosterone replacement therapy, we recommend staying well hydrated, maintaining regular physical activity, and avoiding prolonged periods of immobility. If you have risk factors for cardiovascular disease, we may recommend additional precautions or more frequent monitoring. It's crucial to inform your Bodyline healthcare provider about any symptoms that might suggest a blood clot, such as leg pain or swelling, chest pain, or shortness of breath, so that appropriate action can be taken immediately.

Increased Risk of Prostate Cancer

TRT can increase the risk of prostate cancer, especially in men with a history of prostate cancer or other prostate conditions. If you are at risk of this condition already, TRT may not be the right solution for you. The relationship between testosterone and prostate health is complex and has been the subject of considerable research and debate. Whilst testosterone does not cause prostate cancer, it can potentially stimulate the growth of existing prostate cancer cells, which is why men with active or suspected prostate cancer should not use TRT.

Before starting testosterone replacement therapy at Bodyline, we conduct a comprehensive assessment of your prostate health. This includes measuring your prostate-specific antigen (PSA) level through a blood test and discussing any urinary symptoms you may be experiencing. Men over 50, or those with risk factors for prostate cancer, may also be advised to have a digital rectal examination to assess the prostate. These baseline assessments help identify any existing prostate issues that might contraindicate TRT.

During testosterone replacement therapy, we monitor your PSA levels regularly, typically every three to six months initially, then annually once stable. A significant rise in PSA levels warrants further investigation, which may include referral to a urologist for additional testing. It's important to note that current research suggests that TRT, when properly monitored, does not increase the risk of developing prostate cancer in men who don't already have the disease. However, caution and vigilance remain important, which is why regular monitoring is a key component of safe TRT administration.

Some men may experience benign prostatic hyperplasia (BPH) or enlargement of the prostate whilst on testosterone replacement therapy, which can cause urinary symptoms such as difficulty starting urination, weak stream, or frequent urination, particularly at night. If you develop these symptoms, it's important to discuss them with your healthcare provider at Bodyline, as they may require treatment or adjustment of your TRT regimen.

Acne and Oily Skin

TRT can cause acne and oily skin, leading to skin irritation and discomfort. This occurs because testosterone stimulates the sebaceous glands in the skin to produce more sebum, an oily substance that can clog pores and lead to acne breakouts. For some men, particularly those who experienced acne during adolescence when testosterone levels naturally surge, this can be a troublesome side effect of TRT. The acne associated with testosterone replacement therapy typically appears on the face, chest, back, and shoulders.

The severity of acne from TRT varies considerably between individuals. Some men experience only mild oiliness or occasional breakouts, whilst others develop more significant acne that requires treatment. The good news is that this side effect is generally manageable with appropriate skincare and, if necessary, dermatological treatment. Simple measures such as washing affected areas twice daily with a gentle cleanser, using non-comedogenic (non-pore-blocking) moisturisers and sunscreens, and avoiding touching or picking at the skin can help minimise breakouts.

If acne becomes problematic, there are several treatment options available. Over-the-counter treatments containing benzoyl peroxide or salicylic acid can be effective for mild to moderate acne. For more severe cases, prescription treatments such as topical retinoids, oral antibiotics, or other medications may be necessary. At Bodyline, we can provide advice on managing skin-related side effects of TRT and can refer you to a dermatologist if needed. In some cases, adjusting the dose of testosterone may help reduce skin-related side effects whilst still providing the desired benefits.

It's worth noting that whilst acne can be frustrating, it's generally a temporary issue that improves as your body adjusts to testosterone replacement therapy. Many men find that skin-related side effects are most noticeable in the first few months of treatment and gradually improve over time. Maintaining good skincare habits and seeking appropriate treatment when needed can help you manage this side effect without compromising the benefits of TRT.

Sleep Apnea

TRT can worsen sleep apnea, leading to sleep disturbances and daytime fatigue. Sleep apnoea is a condition characterised by repeated pauses in breathing during sleep, often accompanied by loud snoring. These breathing interruptions can occur dozens or even hundreds of times per night, disrupting sleep quality and reducing oxygen levels in the blood. Men with untreated sleep apnoea often wake feeling unrefreshed, experience excessive daytime sleepiness, and have difficulty concentrating.

Testosterone can worsen sleep apnoea through several mechanisms. It may affect the muscles that control the upper airway, making airway collapse more likely during sleep. Testosterone can also alter breathing control centres in the brain and may suppress the arousal response that normally wakes you when breathing stops. Additionally, because TRT can lead to weight gain in some men, particularly if combined with increased muscle mass and appetite, this weight increase can contribute to sleep apnoea severity.

Before starting testosterone replacement therapy at Bodyline, we ask about symptoms that might suggest sleep apnoea, such as loud snoring, witnessed breathing pauses during sleep, waking with a choking or gasping sensation, morning headaches, or excessive daytime sleepiness. Men with suspected sleep apnoea should be evaluated and, if necessary, treated before starting TRT. If you have diagnosed sleep apnoea, it's essential that you're using appropriate treatment, such as continuous positive airway pressure (CPAP) therapy, before beginning testosterone replacement.

During testosterone replacement therapy, it's important to remain alert for symptoms suggesting new or worsening sleep apnoea. If you develop these symptoms, inform your Bodyline healthcare provider promptly. A sleep study may be recommended to assess the severity of sleep apnoea and determine appropriate treatment. In some cases, adjusting the testosterone dose or timing of administration may help minimise effects on sleep. Treating sleep apnoea is important not only for quality of life but also for overall health, as untreated sleep apnoea increases the risk of cardiovascular disease, stroke, and other serious health conditions.
