What Is Testosterone Replacement Therapy (TRT)? 

Testosterone is an essential male sex hormone produced in the testicles. Men need healthy testosterone levels to maintain their sex drive, sperm count, muscle mass, bone health, cognitive function, red blood cell production, and several other critical bodily functions.

As many men age, their testosterone levels can decline, resulting in many adverse side effects. If you have noticed a decline in your testosterone levels, you may experience various negative symptoms. Testosterone replacement therapy (TRT) can help boost your testosterone levels to improve your health and vitality.

Types of Testosterone Replacement Therapy

Testosterone replacement therapy at our London clinic is only prescribed following a complete medical assessment and diagnosis of low testosterone levels. We have several testosterone replacement therapy options conveniently located in London for you to choose from. These include:

Testosterone transdermal: This can be in the form of gels or a patch that releases minute amounts of the hormone into the skin and is applied once per day, usually in the evening.

Testosterone injections: The most popular brand for a sustained testosterone injection is Nebido, which is typically administered every 10 to 14 weeks. Needles and a sharps bin are available through our in-house, ongoing sharps bin disposal service.

 Testosterone tablets: Restandol is the most common brand used for the prevention and management of androgen deficiency, which causes low testosterone.

Pros and Cons of Testosterone Therapy

Numerous studies have shown that testosterone replacement therapy is beneficial for symptomatic men with low testosterone levels; however, the success of TRT will ultimately be determined by how the individual’s physiology responds.

Research indicates that the pros of low testosterone treatment include:

• Increased cognitive function: According to research, testosterone treatment in males with low testosterone levels can have neuroprotective benefits, resulting in improved cognitive function and memory.

• Improved mood and energy levels

• Increased strength and muscle mass: Testosterone acts as a performance-enhancing drug for many reasons. This hormone helps to build strength and muscle mass, as well as maintain fat loss. Active men may notice they gain muscle more easily after starting low testosterone treatment.

• Lower cholesterol levels: Clinical trials have shown low testosterone treatment to lower cholesterol levels. 

• Lower risk of:

• Heart disease and heart attack
• Osteoporosis
• Stroke.

According to research, the drawbacks of low testosterone treatment include:

Long-term treatment: TRT may inhibit the body’s natural testosterone production by making the body more reliant on the higher testosterone provided. Once TRT ends, most men will start producing testosterone again naturally. But it’s important to remember that the longer you take TRT, the more time it will take natural testosterone production to return. 

Testosterone replacement therapy is generally implemented as a long-term treatment simply because if you were diagnosed with low testosterone levels before starting TRT, you would probably return to the same low levels if you stop receiving TRT.

• Increased risk of:

• Blood clots, deep vein thrombosis (DVT) and a pulmonary embolism (PE), which occur when a blood clot breaks loose and travels to the lung, which can be fatal.
• Oedema, which causes the accumulation of extra fluid in the body that results in swelling of the tissues, is most often seen in the legs and ankles.
• Infertility.

Testosterone Replacement Therapy Side Effects

The side effects of TRT will depend on various factors and may be reversed by altering the type of low testosterone treatment. Common side effects associated with TRT include:

• Male pattern baldness
• Increase in body hair.
• Acne
• Gynecomastia (Growth of male breast tissue)
• Lower sperm count
• Testicular atrophy (shrinking of testicles)

Is Testosterone Therapy Safe?

According to the data that is now available, TRT is generally seen to be safe for males, with only a slight intrinsic risk of negative outcomes in a few high-risk groups of men who have a variety of medical comorbidities. Two key concerns in the safety of TRT are:

• Prostate cancer: The total prostate size does grow in older men receiving testosterone therapy. However, this increase is similar to the increase in prostatic hypertrophy observed in older men who are not using TRT.TRT has been linked to mild elevations in blood PSA, but these levels are still within safe clinical limits and do not provide strong evidence of an elevated risk of prostate cancer. Men taking TRT should have regular PSA monitoring.

• Cardiovascular disease: Research has indicated that TRT may increase the risk of cardiovascular disease or death rates. Data also shows that men with major comorbidities are more susceptible to cardiovascular complications.

What Are Low Testosterone Symptoms?

Key signs that you may be suffering from low testosterone are:

• A drop in your libido
• Less desire for sexual activity
• Changes in mood
• Loss of cognitive function
• Fatigue
• Feelings of depression
• Lower energy levels
• Trouble concentrating
• Insomnia
• Erectile dysfunction and the inability to maintain an erection

You may have low testosterone levels when experiencing these signs and negative symptoms. The best way to know for sure is to book a free consultation with a UK testosterone expert at our London clinic.

What Causes Low Testosterone?

It’s normal for a man’s testosterone to lower as he ages, but even men in their 20s and 30s can experience symptoms of low testosterone. Several factors cause this — often driven by lifestyle choices. These may be:

• Having an unhealthy diet
• Smoking
• Lack of exercise
• Weight gain
• Leading a high-stress life
• Previous steroid use.

Can I Increase My Testosterone Levels Naturally?

You can boost your testosterone levels naturally. One of the most significant strategies to treat low testosterone in overweight or obese persons is to decrease body fat through a combination of high-intensity exercise and a healthy diet. Reducing excess body fat can help rebalance hormones, improve insulin sensitivity, reduce inflammation, and reduce oestrogen levels associated with fat deposits. 

Research indicates that weight training could briefly boost testosterone levels. Stress reduction may be important because cortisol, which is elevated by stress, may inhibit testosterone production.

Men aged 50 or over with low testosterone levels will generally require TRT to raise their levels. However, maintaining low body fat and addressing symptoms of stress and anxiety are still important.

More information

Our extensive consultation and tests will give us the results we need to determine if you are a good candidate and what your protocol should consist of.
Yes! There are many things we can help in terms of sex drive and erection quality. Low testosterone level is linked to poor erection quality, so restoring your hormone balance will certainly improve your sex life. One of the largest placebo-controlled studies showed that “older men with low libido showed more interest in sex” and got their groove back after TRT.
Every person will have a bespoke treatment plan, but we encourage at least six months of treatment to see results. We will track your progress to ensure your plan is working and is correct as your testosterone improves.
Every person will have a bespoke treatment plan. Studies show that with injections, men regain sexual interest and increased libido in as little as three weeks, with changes in erections taking anywhere from three weeks to a couple of months.

Noticeable improvements in mood and overall quality of life are detectable very early into TRT, but we encourage at least six months of treatment to see results. We will track your progress to ensure your plan is working and is correct as your testosterone improves.
According to the data from numerous clinical studies, prostate cancer risks while taking TRT are minimal. Most researchers acknowledge that while testosterone replacement therapy (TRT) does not typically cause prostate cancer (PC), it may nonetheless accelerate the progression of cancer in men who already have prostate cancer.
Low sperm count is a side effect of TRT. Normally, this will revert once TRT is stopped, but for some men, infertility due to TRT can be permanent. You should always discuss with your doctor if you want to have children in the future before starting TRT.
We will create a well-planned TRT treatment to help negate any potential negative side effects. However, some men experience mild side effects like irritability, acne, weight gain, headaches, nervousness, and — in rare cases — prolonged erections. Previously, testosterone replacement was connected to cardiovascular issues, but more recent research showed no increased risk of heart attacks or strokes for men on TRT.
In the UK, testosterone replacement therapy is available through the NHS.
However, due to increased pressure on waiting lists for referrals, many men find that getting the help they need through their NHS GP is a lengthy process.
Using a private clinic like Harley Street MD in London will give you faster access to the testosterone replacement treatment you need. We are experienced in giving the best possible treatment protocol based on efficacy. Men receiving low testosterone treatment at our clinic receive a thorough assessment and ongoing monitoring to ensure the treatment is optimised at all times.
