Scientists say frequent ejaculations could be the key to keeping the semen-producing gland healthy and avoiding cancer.
In fact, in a study of almost 32,000 men published in the journal of European Urology, researchers found high levels of sexual activity can reduce the risk of contracting prostate cancer by 33 per cent.
The optimum number is 21 ejaculations per month.
