A recent Chinese study, published in the Journal of Sexual Medicine, reveals a link between the high number of ejaculations per week and the risk of developing prostate cancer.
Decreasing the frequency of weekly ejaculations reduces the risk of prostate cancer
While many studies have proven that premature ejaculation is a means of preventing prostate cancer, this new research contradicts these claims. To reach this conclusion, the research was based on 22 studies with the participation of 55,490 people.
The researchers therefore observed that to reduce the risk of prostate cancer, the frequency of ejaculation should be between 2 and 4 ejaculations per week. Sexual hyperactivity is therefore no longer protective.
Other factors are singled out: the number of sexual partners and the age at first intercourse
The more sexual partners there are, the more men are at risk of prostate cancer. Having more than 10 female partners would multiply by 1.10 the risk of contracting prostate cancer. While raising the age of first sexual intercourse to an advanced age, would decrease the risk by 4% every five years.
According to the researchers, these results may be explained by a greater exposure to sexually transmitted infections (STIs). These new factors are therefore not to be taken lightly when we know that prostate cancer affects around 50,000 men in France each year.
