Jerking Off Cuts Prostate Cancer Risk By 33 Percent: Male Orgasm Flushes Out Harmful Toxins, Theory Says

Leave a comment

Many men know a healthy diet and lifestyle provides some protection against prostate cancer. Eating less red meat, animal fats, and dairy fats and adding more fruits and vegetables promote good health, but science suggests men can also give their prostate a helping hand, literally. A study published in European Urology found having sex or jerking off can lower the risk of prostate cancer via the male orgasm.

There’s a link between how much men masturbate and their likelihood of developing prostate cancer. A total of 21 orgasms a month, either by having lots of sex or jerking off, can reduce the risk of disease by 33 percent.

“These findings provide additional evidence of a beneficial role of more frequent ejaculation throughout adult life in the etiology of PCa [prostate cancer], particularly for low-risk disease,” wrote the researchers from Harvard T.H. Chan School of Public Health, in the study.

However, it remains unclear why having this many orgams per month is good for the prostate.

One theory is that ejaculation flushes out harmful toxins and bacteria in the prostate gland that could cause inflammation. The prostate works by providing a fluid into semen during ejaculation that activates sperm, and prevents them from sticking together. High concentrations of potassium, zinc, fructose, and citric acid are drawn from the bloodstream.

Previous research has shown carcinogens found in cigarette smoke, like 3-methylcholanthrene, are also found in the prostate. This means carcinogens can build up over time, especially if men ejaculate less, which is known as the prostatic stagnation hypothesis. In theory, the more a man “flushes out” the ducts, the fewer carcinogens that are likely to linger around and damage the cells that line them.

Another theory proposed is ejaculation can lead the prostate glands to mature fully, which makes them less susceptible to carcinogens.

Approximately 32,000 men were surveyed on their number of orgasms as researchers tracked  those who developed prostate cancer over the course of decades. The study was a 10-year follow-up on questions answered on ejaculation frequency in 1992 and followed through to 2010. Average monthly ejaculation frequency was assessed during three periods: age 20–29; age 40–49; and the year before the questionnaire was distributed.

The researchers concluded daily masturbation throughout adulthood had a protective effect against prostate cancer. These findings echo results from a 2008 Harvard study that found there was no increased risk of prostate cancer related to age of ejaculation, but benefits increased as men aged. Yet, other studies have found men experience a reduced risk of prostate cancer if they frequently masturbated during young adulthood.

Jerking off as an effective preventative measure for prostate cancer remains murky. These studies suggest there is a connection between the two, but its effects seem to fluctuate depending on a man’s age. This warrants further research to determine what age group can reap the most benefits from daily masturbation for prostate health.

Prostate cancer mainly affects men over 50, and risk increases with age. About six in 10 cases of prostate cancer are found in men older than 65, according to the American Cancer Society. Other risk factors include race, genetics, weight, physical activity, diet, height, and chemical exposure.

The exact causes of prostate cancer remain unknown, but sticking to a healthy diet and lifestyle could offer protection. Perhaps men who give themselves a helping hand in the bedroom can also improve their prostate health. After all, relaxing and reducing stress can help increase longevity, and decrease the onset of disease.

For seniors, sexual activity is linked to higher quality of life

Leave a comment

(Reuters Health) – Older adults who value sexual activity and engage in it have better social lives and psychological well-being, according to a small study in Scotland.

Older adults said “they miss and want to engage in sexual behaviors, whether that be a kiss to intercourse,” said study coauthor Taylor-Jane Flynn in an email. “For many, these behaviors remained an important element in their life.”

Flynn, a psychology PhD candidate at Glasgow Caledonian University, said the study was inspired by her work as a health care assistant for elderly people.

Although quality of life is a key consideration for older adults, sexuality is rarely studied, write Flynn and Alan Gow, an associate professor of psychology at Heriot-Watt University in Edinburgh, in the journal Age and Ageing.

The researchers recruited 133 Scottish adults aged 65 and over by distributing questionnaires at local clubs, small businesses and older people’s groups.

About half the participants lived with a spouse or partner.

The questionnaire asked how often in the last six months participants had engaged in six sexual behaviors: touching/holding hands, embracing/hugging, kissing, mutual stroking, masturbation and intercourse.

Participants also rated how important those behaviors are to them, on a five-point scale ranging from “not at all important” to “very important.”

Additionally, the questionnaires assessed participants’ quality of life based on physical health, psychological health, social relationships and environment.

Between 75 and 89 percent said they’d engaged in kissing, hugging and holding hands or touching. Men and women scored about the same for frequency and importance of sexual behaviors overall, and for quality of life.

Although people with frequent sexual activity also placed higher importance on it, the analysis found the two measures were associated with different aspects of quality of life.

Participants reporting more frequent sexual behavior rated their social relationships as higher quality, while people who found sexual activity to be important had higher scores for psychological quality of life.

Overall, however, seniors’ health status had the strongest impact on all aspects of quality of life.

John DeLamater, a sociology professor at the University of Wisconsin – Madison, said the fact that participants were recruited in community settings – which may attract more healthy and active older people – might affect the results.

“If they are generally healthier (which the results show to be associated with quality of life), they are probably more sexually active,” DeLamater said in an email.

For people who have valued sexuality throughout their lives, he noted, “continuing activity provides protection against a sense of aging and loss, and of continuity if the person is in a long-term relationship.” That may explain the links between sex and well-being found in the study, he said.

While the current study only looked at associations and cannot determine whether sexuality raises quality of life, Gow noted, he hopes that future research will focus more on this subject.

“What we hope is that our current findings encourage other researchers interested in the determinants of health and well-being in older adults to also consider sexual behaviors,” Gow said in an email.

The sexuality of older people should be considered and encouraged, DeLamater said. “We should encourage couples to spend time alone, provide arrangements in care facilities that enable sexual intimacy, provide sexual health information in medical settings.”
