Wow, according to the major Harvard Health Professionals Follow-Up Study (tracking ~32,000 men), ejaculating 21 times a month is linked to about a 20-31% lower risk of prostate cancer compared to just 4-7 times a month. The benefit showed up for frequency in your 20s, 40s, and overall, especially for low-risk cases. It held after adjusting for PSA testing and other lifestyle factors.
The idea? Regular ejaculation may help flush out potential carcinogens or change prostate tissue in a protective way.
@letsfcancer has leaned into this with cheeky PSAs and videos encouraging guys to "milk the moose" 21 times monthly as a fun prevention angle—alongside real screening.
Hey, if it lowers the risk, you've gotta do your part, right? It's not a guarantee (more research needed, and it doesn't replace PSA tests or healthy habits), but it's one of the more enjoyable "duties" out there. Stay consistent, get checked when it's time, and keep fighting the good fight.
