Prostate cancer is a major health concern for men, particularly as they grow older. But does going without sex increase the risk? Here is what men need to know about the causes, warning signs, risk factors and early detection of prostate cancer.

Prostate cancer is one of the health conditions men should understand, yet several misconceptions continue to surround the disease. One common question is whether men who go for long periods without sex are more likely to develop prostate cancer.

The simple answer is no. There is no established scientific evidence that a lack of sex causes prostate cancer. Men who are single, abstinent or not sexually active are not automatically at greater risk because of their sexual activity.

However, research has examined whether ejaculation frequency may be associated with prostate cancer risk. Some studies have suggested a possible link between more frequent ejaculation and a lower risk, but this does not prove that ejaculation prevents cancer. Men should not regard regular sex as a guaranteed way to protect themselves from the disease.

Understanding the actual risk factors and recognising potential warning signs are more important steps towards protecting men’s health.

What Is Prostate Cancer?

The prostate is a small gland found in men, located below the bladder and surrounding part of the urethra, the tube through which urine leaves the body.

The gland produces fluid that forms part of semen and helps support sperm function.

Prostate cancer develops when cells in the prostate begin growing abnormally and uncontrollably. Some forms of the disease grow slowly and may remain within the gland for years, while others are more aggressive and can spread to other parts of the body, including the bones.

Although the disease is more common in older men, younger men are not completely exempt from the risk.

What Causes Prostate Cancer?

Doctors have not identified one single cause responsible for every case of prostate cancer. However, research has established several factors that can increase a man’s chances of developing the disease.

Age is one of the most important risk factors. The likelihood of prostate cancer increases as men grow older, with most cases occurring in men above 50.

Family history also matters. A man whose father or brother has had prostate cancer may face a higher risk, particularly if the relative was diagnosed at a younger age or several close relatives have had the disease.

Men of African ancestry are also recognised as a higher-risk group in prostate cancer research. This makes awareness and discussions about early detection particularly important for Nigerian men.

Certain inherited genetic changes, including changes in the BRCA2 gene, can further increase a man’s risk.

Having one or more of these risk factors does not mean a man will definitely develop prostate cancer. Equally, a man without any known risk factors can still develop the disease.

Can a Man Develop Prostate Cancer Without Having Sex?

Yes. A man can develop prostate cancer regardless of whether he is sexually active.

There is no established evidence that remaining single, abstaining from sex or going for months without ejaculation directly causes the disease.

The suggestion that semen must be released regularly to prevent prostate cancer is not supported by sufficient evidence to be treated as medical advice.

Although some observational studies have found an association between frequent ejaculation and a lower risk of prostate cancer, researchers have not established that ejaculation itself is responsible for the difference.

Men should therefore avoid making decisions about their sex lives based on the belief that sex is necessary to prevent prostate cancer.

Warning Signs Men Should Not Ignore

One of the challenges with prostate cancer is that it may not cause noticeable symptoms in its early stages. A man can feel healthy and still have the disease.

When symptoms occur, they may include:

• Frequent urination, particularly during the night.
• Difficulty starting urination.
• A weak or interrupted urine stream.
• Difficulty emptying the bladder completely.
• Blood in the urine or semen.
• Persistent pain in the lower back, hips or pelvis.
• Unexplained weight loss, particularly in advanced disease.

These symptoms do not automatically mean a man has cancer. An enlarged prostate, urinary tract problems and inflammation of the prostate can cause similar symptoms.

However, persistent urinary problems, blood in the urine or semen, or unexplained pain should be assessed by a healthcare professional. A man who suddenly cannot pass urine needs urgent medical attention.

Waiting until symptoms become severe before seeking medical care can delay diagnosis.

How Can Men Check for Prostate Cancer?

One way to assess the possibility of prostate cancer is through a prostate-specific antigen (PSA) blood test.

The test measures the level of PSA, a protein produced by cells in the prostate. A raised PSA level can indicate a prostate problem, but it does not automatically mean cancer is present. An enlarged prostate and inflammation can also increase PSA levels.

A doctor may recommend further assessment, which can include a prostate examination, an MRI scan and, when necessary, a biopsy to confirm whether cancer is present.

Screening is not a perfect process, and PSA testing can sometimes lead to unnecessary investigations or the detection of cancers that might never cause serious problems. Men should discuss the potential benefits and risks with a qualified healthcare professional.

For men of African ancestry, including Nigerians, a discussion about screening from around age 45 is a reasonable starting point under American Cancer Society guidance. Men with multiple close relatives diagnosed at a young age may need to discuss it even earlier.

Men who already have symptoms should seek medical assessment rather than waiting for a routine screening appointment.

Can Prostate Cancer Be Treated?

Yes. Many cases of prostate cancer can be treated successfully, especially when the disease is detected before it spreads.

Treatment depends on the stage of the cancer, how quickly it is growing, and the patient’s age and general health.

Options include active surveillance for selected slow-growing cancers, surgery to remove the prostate, radiotherapy, hormone therapy and other treatments for advanced disease.

Not every patient needs the same treatment. Some men can be monitored closely, while others require more intensive care.

Early assessment can help doctors identify the disease and determine the most appropriate treatment.

What Can Men Do to Protect Their Health?

There is no guaranteed method of preventing prostate cancer. Nevertheless, men can take practical steps to support their health and make informed decisions about early detection.

These include maintaining a healthy weight, engaging in regular physical activity, eating a balanced diet and discussing personal risk factors with a healthcare professional.

Men should pay particular attention to their age and family history. Those with a father or brother who had prostate cancer should inform their doctor, especially if the relative was diagnosed before age 65.

Most importantly, men should not rely on sexual activity, supplements or unproven remedies as protection against cancer.

Final Thoughts

The claim that a lack of sex causes prostate cancer is not supported by established medical evidence. Although some research has explored a possible association between frequent ejaculation and reduced risk, it has not proved that ejaculation prevents the disease.

Age, family history, African ancestry and certain inherited genetic changes are better-established risk factors.

Men should understand the warning signs, seek medical attention when symptoms develop and discuss appropriate screening with a healthcare professional.

The most important message is simple: a man’s sexual activity does not determine whether he will develop prostate cancer. Knowing his risk factors and seeking appropriate medical care are far more important.
