Prostate health can be a pretty awkward subject, so prepare to blush at this new research from Harvard University.

Scientists say frequent ejaculations could be the key to keeping the semen-producing gland healthy and avoiding cancer, reports news.com.au.

In fact, in a study of 32,000 men, they found high levels of sexual activity can reduce the risk of contracting prostate cancer - and that 21 ejaculations per month is the ideal number to protect yourself.

In New Zealand, prostate cancer is the most common cancer in men, with around 3000 registrations each year and about 600 deaths from prostate cancer each year, so it's advice worth considering.

Obviously, that's in addition to things like maintaining a good diet, exercising frequently, and getting regular check-ups.
