“Ejaculating at least 21 times a month significantly reduces a man’s risk of prostate cancer,” is the headline on the Mail Online. This is based on research from the US that asked men how often they ejaculated per month and subsequent reporting of prostate cancer.
They found that men who ejaculated 21 times or more a month were less likely to report prostate cancer at follow-up than those ejaculating four to seven times per month.
However, it does not prove that ejaculating more frequently prevents cancer, only that it is associated with a reduction in risk. It might be that a range of other factors such as genetics, lifestyle, number of children, diet, nature of sexual activity and education contribute to this risk, but we cannot say for sure what factors might increase the risk.
The researchers offer a number of hypotheses why ejaculation may help reduce prostate cancer risk, such as reducing stress or keeping cell metabolism well regulated. But these suggestions remain in the realm of speculation.
Despite any lurid tales you may have heard growing up, masturbationis entirely safe. So if you want to do it as a preventative method then it wouldn’t pose any health risks.
Initial signs of prostate cancer usually involve problems with urination, such as needing to urinate more frequently, due to the prostate getting larger. While prostate enlargement can occur as men grow older, it is important to check symptoms like these with your GP.
