So many opportunities for correlation not causation. One obvious correlation could be testosterone: higher testosterone leading to less prostate cancer. Of course higher testosterone has multiple causes. I knew a girlfriend of a guy taking roids, both in their twenties: she said he was insatiable in her opinion (I think she limited access to three times a day, because he just wanted more).

>So many opportunities for correlation not causation. When people point this out (which they do on every single human-related study that makes the front page), it implies that the article is suggesting causation somewhere. I don't see this article suggesting that anywhere; what I find toward the end is this: >The studies from the United States and Australia do little to answer these critical questions — but they do o…

> Even so, the apparent protection extended to all age groups. In all, men who averaged 4.6–7 ejaculations a week were 36% less likely to be diagnosed with prostate cancer before the age of 70 than men who ejaculated less than 2.3 times a week on average. Sure, they use "apparent" as a weasel-word but "protection" is clearly suggesting causation.

That's not a weasel-word, that word is there precisely to point out that the protection isn't verified. Combined with their conclusion that I already pointed out, there really is no suggestion of causation here.

There is no ambiguity in the statement "The studies...do little to answer these critical questions," it means the studies are inconclusive and shouldn't be treated otherwise.

Also seems possible that married men, who are at a lower risk for almost every negative health outcome there is, are also at a lower risk for prostate cancer due to what is outlined in the paper.

Married men seem more likely to have frequent (ahem) both due to literally living with their partner, as well as having a lower likelihood of depression, higher testosterone (the higher test generally would lead to the marriage) etc.

Most of that community appears to be based on woo and bad analysis of science/biology, so I imagine they'd likely dismiss this study out of hand regardless. But also, we shouldn't forget this: > The studies from the United States and Australia do little to answer these critical questions — but they do open a new avenue for research This isn't a fully understood area of research yet.

...and oil companies were among the first to predict global warming and might have coined CO2 budgets. Who came up with something doesn't really matter for the thing's merit, especially when it lives a life of its own. People fill in nonutnovember as they want, not per whatever extremist views. I don't really see the point of sidetracking the conversation into a political corner.

This study is talking about testosterone changes in relation to number of days of ejaculation abstinence.

It says nothing about testosterone levels vs ejaculation frequency.

Are you married? My anecdotal evidence points in the opposite direction.

Those are rookie numbers. You gotta pump up those numbers. https://www.youtube.com/watch?v=CES1OIkFhg4

I’m probs a coomer because I’d average 80/ month.

Are you a teenager??

If every 7 times per month your risk decreases by 31%, the average HN user might have less than 1% risk.

Based on what exactly?
