Erectile Dysfunction and Testosterone Replacement Therapy (TRT)

If you’re experiencing erectile dysfunction (ED) or suspect low testosterone levels may be impacting your quality of life, you’re far from alone. ED and low testosterone (or low-T) affect millions of men, often impacting not only sexual health but also self-esteem and relationships. At Omniya Clinic London, we offer a personalised approach to TRT, helping men regain their vitality and navigate the complex relationship between ED and low testosterone with informed guidance and proven treatments.

What is Erectile Dysfunction?

Erectile Dysfunction, commonly known as ED, is the inability to achieve or maintain an erection firm enough for sexual activity. While occasional erectile issues are normal and may be linked to temporary stresses for example tiredness, chronic ED can indicate underlying health concerns. ED becomes more common as men age, but it is by no means an inevitable part of getting older. Many physical (or organic) and psychological (non-organic) factors contribute to ED, making each case unique.

Physical Causes of ED

ED is often tied to physical health conditions that impact blood flow or nerve function, including:

• Metabolic Disease: Metabolic conditions like obesity, high blood pressure, high cholesterol, and diabetes increase the risk of developing atherosclerosis (narrowed arteries), which can impede blood flow to the penis causing erectile dysfunction(1-3). This is one of the main processes in the development of heart disease and stroke. Often erectile dysfunction can be an early manifestation of this process.
• In the case of diabetes, poor blood sugar control makes it three times more likely for an individual to suffer from ED. Obesity is another important factor influencing erectile dysfunction for a number of reasons, both hormonal and non-hormonal.
• Increased body fat causes lower testosterone levels and increased oestrogen, it is also a risk factor for atherosclerosis as well as often causing psychological issues around self image that have a knock on effect on sexual function (4-6).
• There are a number of hormonal causes of ED including too much prolactin and too little thyroid hormone, unquestionably however hypogonadism (too little testosterone) is the most important physical cause. Testosterone is the main driver of sexual desire and has an important dilating effect on the blood supply to the penis. In it’s absence achieving normal erectile function is extremely difficult(7,8).

Psychological Causes of ED

Psychological factors are always involved in ED; whether they are the root cause or not is up to debate. The penis is controlled by the parasympathetic nervous system. This is counteracted by the sympathetic nervous system involved in the fight or flight response, a response that can be triggered by many stresses including tiredness. Common psychological causes are:

• Stress and Anxiety: High stress and “performance” anxiety can stop you from being able to get an erection. Psychosexual therapy is great for the latter.
• Depression: Depression can lower libido and make it harder to have sex. And antidepressants, although they may be life saving in some cases, are well known for their sexual side effects including low libido and ED.
• Relationship Issues: Emotional disconnection or unresolved issues with a partner can also show up as ED, and further complicate intimacy and communication(9).

How Testosterone Influences Erections

Low testosterone is associated with two primary impacts on erectile function:

1. Central Nervous System Influence: Testosterone stimulates the release of dopamine, serotoninand other neurotransmitters essential for sexual arousal and erectile function. It also has an important neuroprotective role, helping nerves function properly(7,8,10).
2. Blood Flow Regulation: Testosterone increases the levels of nitric oxide, which dilates the blood vessels supplying the penis, thereby allowing more blood to enter Nitric oxide is also the key neurotransmitter for erectile function, in other words the nerves involved in gaining and maintaining an erection rely on the use of nitric oxide for this function(11).

How Testosterone Influences Erections

Men with low testosterone may notice a decrease in spontaneous erections (like morning erections) and may find it difficult to achieve an erection in arousing situations. However, it’s important to note that low testosterone is rarely the sole cause of ED; it often interacts with other factors, such as vascular health and psychological well-being.

Medical Evidence on Testosterone and Sexual Health

Medical studies provide valuable insight into the connection between testosterone and sexual function.  However, it’s often not a standalone solution for ED, especially if underlying vascular or psychological factors are at play. Importantly, the duration of erectile dysfunction has an important bearing on how successful treatment might be.

The Relationship Between Low Testosterone and ED

The relationship between low testosterone and ED is multi-faceted. While low testosterone can certainly reduce sexual desire, it is typically only one part of the picture when it comes to erectile issues. TRT can help improve libido in men with low testosterone but may not fully address ED, particularly when the root cause is related to blood flow or mental health. Furthermore, if ED has been present for some time, it is not uncommon for scar tissue to build up in the penis and this then remains an obstacle in the way of achieving good erectile function.

How Testosterone Replacement Therapy (TRT) Can Help with ED

For men with low testosterone, TRT can be a helpful addition to an ED treatment plan, especially when low testosterone levels are affecting sexual desire and overall sexual health. TRT works by bringing testosterone levels back into a healthy range, typically through injections, topical gels, patches, or implants.

How TRT can help with erectile dysfunction

Benefits of TRT for Sexual Health

Studies indicate that TRT may support sexual function in men with low testosterone by:

1. Increasing Libido: Men on TRT often report significant improvements in sexual interest and desire.
2. Improving Erectile Function: While TRT alone may not resolve all cases of ED, it can enhance the effectiveness of other treatments, such as PDE-5 inhibitors (Viagra, Cialis, Levitra), which support blood flow to the penis(12).

TRT and Phosphodiesterase-5 (PDE-5) Inhibitors: A Combined Approach

TRT combined with PDE-5 inhibitors offers a comprehensive approach to ED treatment. PDE-5 inhibitors increase blood flow to the penis, helping support erections. Multiple studies show that men using both TRT and PDE-5 inhibitors have more consistent improvements in erectile function than those using only one form of treatment, making this combination particularly useful for men with low testosterone and blood flow-related ED(13-15).

Broader Health Benefits of TRT Beyond Sexual Function

TRT offers additional health benefits, especially for men experiencing symptoms of low testosterone:

• Enhanced Mood and Mental Clarity: Low testosterone has been linked to depression and irritability. TRT can improve mood stability, supporting emotional well-being and mental resilience.
• Increased Energy: TRT has been shown to combat fatigue, helping men feel more energised throughout the day.
• Improved Muscle Mass and Bone Health: Testosterone is essential for maintaining muscle and bone strength. Research shows that TRT can support lean muscle growth and reduce osteoporosis risk, an important consideration as men age.

Summarising the Research Findings on TRT and ED

The role of TRT in managing ED and low testosterone has been the focus of numerous studies:

1. A study in the Journal of Clinical Endocrine and Metabolic Medicine found that men with low testosterone experienced significant improvements in sexual desire and satisfaction after TRT(16).
2. The European Journal of Endocrinology reported that TRT is particularly effective for men with both low testosterone and metabolic syndrome, which includes conditions like insulin resistance and obesity that can exacerbate ED(17).
3. A systematic review and meta-analysis concluded that TRT can bring about a marked statistically significant improvement in the International Index of Erectile Function (IIEF) score of men with low testosterone(12).
