Chinese researchers have found that a moderate weekly frequency of ejaculation, that is, between 2 and 4 times a week, is associated with a lower risk of prostate cancer.
A few months ago, British health authorities claimed that the more ejaculations, the lower the risk of prostate cancer. They also encouraged men over 40 to ejaculate at least 21 times a month to reduce the risk of cancer. A new study from the University of Sichuan (China) contradicts them, this time claiming that the risk of prostate cancer increases beyond 4 ejaculations per week (16 per month).
To reach this conclusion, published in The Journal of sexual medicine, Chinese researchers reviewed 22 studies in which 55,490 people participated. They also claim that the risk of cancer also increases with the number of sexual partners (having 10 partners would increase the risk by 10%) as well as the age of the first report.
With more than 71,000 new cases a year, prostate cancer is the most common cancer in France. It is very rare before age 50 and the average age at the time of diagnosis is nearly 70 years old. With a 5-year relative survival estimated at nearly 80%, it is a cancer with a very good prognosis.
