Understanding the connection between Testosterone Replacement Therapy (TRT) and prostate cancer is vital, especially as more men turn to TRT to manage low testosterone levels. This article aims to clarify this complex issue.

Testosterone is a key hormone for men’s health and wellness. However, there has been concern that high levels of testosterone could potentially encourage the growth of prostate cancer cells. It has raised questions about the safety of TRT, even though the relationship between testosterone and prostate cancer is not fully understood yet.

In this article, we will go through the available scientific research on this topic. We’ll discuss studies that suggest a link between TRT and an increased risk of prostate cancer, as well as those that dispute it.

What is Prostate Cancer and What Causes It?

Prostate cancer is a form of cancer that develops in the prostate gland. The prostate, an important part of the male reproductive system, is about the size and shape of a walnut and is located below the bladder. It produces seminal fluid, which nourishes and transports sperm.

Prostate cancer is one of the most prevalent types of cancer among men, particularly those over the age of 50. While some forms of prostate cancer grow slowly and may require minimal or no treatment, others are more aggressive and can spread rapidly to other body parts.

The root cause of prostate cancer remains a mystery to medical professionals. However, several risk factors have been identified. Age is a significant risk factor—the likelihood of developing prostate cancer increases dramatically after the age of 50. 

Another risk factor is genetics. Men with a family history of prostate cancer, especially if their father or brother had the disease, are at a higher risk.

Lifestyle factors can also play a role in the development of prostate cancer. Diets high in red meat or high-fat dairy products and low in fruits and vegetables may increase the risk. 

Obesity, smoking, and exposure to certain chemicals, such as those used in the rubber and paint industries, can also increase the likelihood of developing prostate cancer.

Can Low Testosterone Cause Prostate Problems?

Testosterone, a hormone produced primarily in the testicles, contributes to the growth and development of male sex organs, including the prostate. However, the relationship between testosterone levels and prostate health is complex and not fully understood.

There is ongoing debate within the medical community about whether low testosterone levels can contribute to prostate problems. Some research suggests that low testosterone might be linked to an increased risk of benign prostatic hyperplasia (BPH). This condition causes the prostate to enlarge and can lead to urinary problems. 

There’s also some evidence to suggest that low testosterone might be associated with a higher risk of prostate cancer.

However, it’s important to note that these findings are not definitive. Other studies have found no link between low testosterone and an increased risk of prostate cancer. Furthermore, while testosterone replacement therapy (TRT) can help boost low testosterone levels, its impact on prostate health is still being studied and is not yet fully understood.

Research findings on the Relationship between Testosterone and Prostate Cancer

The relationship between testosterone and prostate cancer has been a subject of ongoing research and debate for many years. The following sections delve into various research findings illuminating this complex topic.

Debunking the Myth of Testosterone and Prostate Cancer

An article titled “Testosterone and prostate cancer: a historical perspective on a modern myth,” published in ScienceDirect, suggests that the widely believed solid relationship between testosterone (T) and prostate cancer (pCA) has failed to hold up under scientific scrutiny. The study indicates that the number of men included in long-term studies is quite small, calling into question the validity of some earlier research.

A New Era: Understanding Testosterone and Prostate Cancer

In another study, “A new era of testosterone and prostate cancer: from physiology to clinical implications“, researchers found no relationship between testosterone and prostate cancer when they analyzed a study population of 3886 men with PCa and 6438 age-matched controls2. This finding further challenges the notion that testosterone directly contributes to the development of prostate cancer.

The Continuing Controversy: Total Testosterone Levels and Prostate Cancer

The relationship between total testosterone levels and prostate cancer: a review of the continuing controversy” presents a comprehensive review of the relationship between total testosterone and subsequent prostate cancer, as well as the risk associated with testosterone replacement therapy (TRT). The article highlights the ongoing controversy and underscores the need for more research.

Revisiting Old Paradigms: Testosterone and Prostate Cancer

Testosterone and prostate cancer: revisiting old paradigms” revisits the previously held belief about the link between testosterone and prostate cancer. It suggests that there is no scientific basis supporting the belief that higher levels of bioavailable testosterone increase the risk of prostate cancer.

Low Serum Free Testosterone: A Marker for High-Grade Prostate Cancer?

Is low serum free testosterone a marker for high grade prostate cancer?” provides intriguing findings. The major findings of this study suggest that men with low free testosterone have more extensive disease based on a higher percent of positive biopsies and high-grade tumors with a biopsy. This suggests that low testosterone levels might be associated with more aggressive forms of prostate cancer.

What You Can Do

Suppose you’re concerned about prostate health or are experiencing symptoms such as frequent urination, difficulty starting or maintaining a urine stream, or even blood in your urine. In that case, it’s important to consult a healthcare professional. They can assess your individual risk factors, provide advice, and discuss potential screening tests for prostate cancer.

For those with low testosterone considering TRT, it’s crucial to have a comprehensive discussion with your doctor about the potential benefits and risks, including any possible effects on prostate health.

Additionally, lifestyle choices can significantly affect prostate health. Regular physical activity, a balanced diet rich in fruits and vegetables, adequate sleep, and avoidance of smoking and excessive alcohol consumption can all contribute to overall wellness. These healthy habits might also help to reduce the risk of developing prostate cancer.

Remember, when it comes to your health, knowledge is power. By understanding the risks and taking proactive steps towards a healthier lifestyle, you can make informed decisions that empower you to take control of your health.


Does testosterone increase the risk of prostate cancer?

The relationship between testosterone and prostate cancer is complex and not fully understood. Some studies suggest that there isn’t a direct link between testosterone levels and the risk of developing prostate cancer. However, more research is needed in this area.

Should you take testosterone if you have prostate cancer?

If you have prostate cancer, the decision to take testosterone should be made in consultation with your healthcare provider. While some studies suggest that testosterone does not increase the risk of prostate cancer, other research indicates that it might accelerate the growth of existing prostate cancer. Therefore, it’s crucial to discuss all potential benefits and risks with your doctor.

Can testosterone cause an increase in PSA?

Prostate-specific antigen (PSA) is a protein produced by cells of the prostate gland. Higher levels of PSA can be a sign of prostate problems, including cancer. Some research suggests that testosterone therapy might increase PSA levels, but the relationship is complex and not fully understood.

Does low testosterone reduce prostate cancer?

Some research findings suggest that low testosterone levels might be associated with more aggressive forms of prostate cancer. However, the relationship between low testosterone and prostate cancer is complex, and more research is needed to fully understand it.

What are the risks of testosterone replacement therapy?

While testosterone replacement therapy (TRT) can help alleviate symptoms of low testosterone, it also comes with potential risks. These may include acne, sleep apnea, blood clots, and a possible increased risk of heart disease. Some studies also suggest that TRT might increase PSA levels, potentially indicating prostate problems. It’s important to discuss these risks with your healthcare provider before starting TRT.
