The Link Between Sex and Prostate Cancer

Sex staves off prostate cancer
by JENNY HOPE

Regular sex can help protect men against prostate cancer, a medical study has found.
It showed that the most sexually-active males had less chance of contracting the potentially-fatal disease.
Frequent sex was also linked to less aggressive prostate cancer, which is more likely to respond to treatment and has a lower likelihood of spreading.
The research by experts in Boston involved nearly 30,000 men - all health professionals - aged between 46 and 81.
Doctors asked about them about their ejaculations in their 20s, 40s and during the previous year - 1991.

Over the next eight years, 1,449 men developed prostate cancer, says a report published yesterday in the Journal of the American Medical Association. On average, the men overall had four to seven ejaculations a month.

However, no increased risk of prostate cancer was seen in males who reported more frequent experiences. The two highest activity levels - 13 to 20 a month and at least 21 a month - were each linked with decreased cancer risks of 14 per cent and 33 per cent.

Protective effect
Researchers think that the activity has a protective effect because the prostate secretes the bulk of the fluid in semen, and sexual activity may flush out cancer-causing chemicals.
Another theory is that it reduces the development of calcifications in the gland that has been linked with cancer.

However, more research was needed because relatively few men in the study reported heavy sexual activity, said Dr Michael Leitzmann, of the National Cancer Institute, who led the survey.
He added: "It's too early to suggest men should change their sexual habits to alter their prostate cancer risk."
The cancer is now the most common form of the disease in men, with around 20,000 cases a year in Britain.

Previous studies found that males who have frequent ejaculations might be more prone to the cancer. But it appears this is because some sexual infections may trigger the disease, rather than the act itself.

Testosterone levels


It remains unclear whether there might still be a connection between frequent sexual activity and prostate cancer, as high levels of the male hormone testosterone fuel a strong sex drive and can also boost the growth of cancer cells.

Two new tests may predict which men might be most at risk from colon cancer and those most likely to die from prostate cancer if surgery or radiation fails, report U.S. researchers.

Men with long-term high levels of C-peptide - an indicator of insulin production triggered by high-fat diets and obesity - are said to be at triple the risk of developing bowel cancer.

A separate study found Prostate Specific Antigen blood test results after cancer treatment could predict patients most at risk of dying from the disease.
Both studies were published yesterday in the Journal of the National Cancer Institute.

How Does Your Sex Life Affect Your Prostate Cancer Risk?
By Chris Iliades, MD

Could how often you ejaculate be linked to prostate cancer? Find out what two studies and two experts say about sex and prostate cancer risk.
What if your chances of getting prostate cancer were somehow tied to how much sex you were having? Some studies have explored that very question — specifically, whether there’s a link between how often you ejaculate (from sex with a partner or from masturbation) and your prostate cancer risk.

More Sex for Prostate Cancer Prevention?

One study, published in the British Journal of Urology International, found that the more ejaculations a man has between the ages of 20 and 50, the less likely he is to develop prostate cancer. The findings suggest that a man in his twenties who ejaculates more than seven times a week has one-third the risk of getting an aggressive type of prostate cancer as a man who ejaculates less than three times a week.

The study, done in Australia, relied on questionnaires filled out by men younger than 70, including 1,079 men who had been diagnosed with prostate cancer and 1,259 men who did not have the disease. The authors of the study speculate that ejaculation may have a protective effect against prostate cancer, but they admit that their findings need to be supported by more research.

Less Sex for Prostate Cancer Prevention?

Another study published more recently in the same journal found that men who have lots of sex in their twenties and thirties are more likely to get prostate cancer, especially if they masturbate a lot.

This study, done at the University of Nottingham in England, also relied on questionnaires. The study participants included 431 men with prostate cancer diagnosed before age 60 and 409 men without prostate cancer. Among its findings were that men with prostate cancer are more likely to have had female partners, more likely to have had a sexually transmitted disease, and more likely to masturbate.

Sex and Your Prostate Cancer Risk

How can two pieces of research come to such different conclusions? "These studies are hard to do and the results may be more confusing than enlightening," says Erik P. Castle, MD, FACS, an associate professor of urology at the Mayo Clinic.
"Asking men to talk about their sex life is not a reliable way to get evidence for a study," adds John Milner, MD, an assistant professor of urology at Loyola Stritch School of Medicine in Chicago. “As of 2012, there's not enough evidence to say anything one way or the other about the number of ejaculations and the risk of prostate cancer."

So what can you do for prostate cancer prevention? For one thing, resist the urge to light up a post-coital cigarette. A recent study from the Harvard School of Public Health, published in the Journal of the American Medical Association, found that cigarette smoking increases your risk for dying from prostate cancer. The study, which included more than 5,000 men who had been diagnosed with prostate cancer and were smokers, found that these men had a 61 percent higher chance of dying from the cancer than non-smokers.

Here are some other tips from the American Cancer Society for reducing your prostate cancer risk:

•   Maintain a healthy weight — there’s a possible link between obesity and prostate cancer.
•   Get 30 minutes of exercise at least five days a week, because this may reduce your risk for aggressive prostate cancer.
•   Eat five servings every other day of brightly colored fruits or vegetables, which have antioxidants that may offer cancer protection.
•   Eats lots of whole grains rather than refined grains.
•   Eat less red meat.

You probably don't need to think about having more sex or less sex to protect yourself from prostate cancer, but you do need to think about getting tested. Talk to your doctor about a PSA test and a rectal exam if you're over 50. If you're African-American or have a family history of prostate cancer, have this discussion if you're over 40.
