An orgasm a day keeps the doctor away. That’s according to new research indicating that men who ejaculate daily reduce their risk of getting prostate cancer by more than 20 per cent.
The study, which was conducted at Harvard Medical School, found that men between the ages of 40 and 49 who ejaculated 21 or more times a month were 22 percent less likely to get prostate cancer than men who only ejaculated four to seven times monthly.
Scientists aren’t sure why regular emissions have such a favourable effect on the likelihood of developing the deadly disease, but have called the findings “particularly encouraging.”
One theory is that a daily release stops the build-up of old cells, which are more likely to turn cancerous.
The researchers also pointed out that routine discharges flush out chemicals in the prostate that may cause cancer.
The prostate is a small tangerine-sized gland located between a man’s penis and his bladder, the main function of which is to produce a thick white fluid that is mixed with the sperm produced by the testicles, to create semen.
The new study is the largest to date on the frequency of ejaculation and prostate cancer.
It followed nearly 32,000 men for 18 years, 3,839 of whom were later diagnosed with prostate cancer.
The results were consistent, even when adjusted to take in factors such as diet and lifestyle.
Dr Jennifer Rider, of Harvard Medical School and Brigham and Women’s Hospital, said the results were “particularly encouraging” but should be interpreted with caution.
“While these data are the most compelling to date on the potential benefit of ejaculation on prostate cancer development, they are observational data and should be interpreted somewhat cautiously,” she said.
“At the same time, given the lack of modifiable risk factors for prostate cancer, the results of this study are particularly encouraging.”
Dr Rider indicated that more research should be carried out into the specific changes in the prostate caused by ejaculation, to understand how it reduces the risk of prostate cancer.
The research was presented earlier this month at the American Urological Society annual meeting in New Orleans.
The causes of prostate cancer are largely unknown, but the chances of developing the disease increase as a man gets older, and black men appear more susceptible than other races.
More than 1.1 million cases of prostate cancer were recorded in 2012, accounting for around eight per cent of all new cancer cases and 15 per cent in men, according to figures from the World Cancer Research Fund International.
