Scientists of the Harvard University in the USA know for sure: multiple ejaculations per month keeps your sperm healthy and helps preventing cancer. When you ejaculate 21 times a month you get a 33% less chance on prostate cancer bonus, for free.
21 ejaculations a month is like 252 times a year, or almost 70% of the days. The American scientists base their study, wich is published in the European Urology magazine, on about 32.000 men.
Prostate Cancer
Prostate Cancer is responsible for one third of the death rate of cancer. It's the deathcause of 7,9 million men yearly worldwide. More than 70% is men above 65 years of age.
The Harvard-scientists say an active sexlife can be an indication of good health, wich on it's own could lower the risk on cancer. That's why not only ejaculating is important, but they advice to eat healthy things and get enough exercise.
My two cents...
Don't you think 21 ejaculations a month is a bit little? Luckely it's a minimum...
I rest my case.
