21 ejaculations per month can reduce the risk of prostate cancer from this news story (Report from Japan but in local Taiwan news)
Comparative effect: This is more significant than walking 30 minutes daily (a 10% reduction) or eating more vegetables (a 7% reduction).
Those are rookie numbers.
That’s less than once a day. Your average teenage boy, I would recommend a blood test for anemia and possibly testosterone therapy, those are the numbers.
I humbly accept my position for the Mens Olympic Team of Taiwan.
We’re bringing home the gold!
Golden Horse has a new meaning now.
Hey! No doxxing!
Someone should tell those poor semen retention guys they are all about to drop dead from cancer 
This is one of those cases where the more the merrier, or the healthier in this case. Right?
Rookie numbers are closer to 70 times a month… it is more the prostrate cancer demographic that needs to be concerned about getting to 21.
If a guy is ejaculating a lot monthly then other things in his life are probably going well with less stress, cortisone, and other negative factors that could effect cancer.
On the positive side at least getting some exercise, maybe better mental and emotional health.
Well, except the DIY guys.
Wait until your prostrate enlarges and you’ll be lucky to get one 
There’s no need to do it yourself. Just stay reasonably attractive or marry someone willing to give you lots of xxx, and you will be fine.
You will know you are in the wrong marriage when you are getting less xxx than when you were single.
yes
Does the article state that as an absolute value or is there a cost for exceeding 21?
Can I smash them all out in one go and have the rest of the month off?
I’ll get the wheelchair on order for that first week of each month.
I always thought walking was overrated!
What about ejaculating while walking? Does that multiply the benefits? 
I’m a big proponent of hot jizz yoga 
Jizz hands over jazz hands.
If some straight dude wants to maintain his health without masturbating, and assume that his partner’s menstruation lasts 7 days, that leaves only 2 days in a month to take a break from engaging in coitus. Sounds like a lot of cardio exercise.
