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).

>higher testosterone leading to less prostate cancer

Is this a well known association? I would assume it to be and opposite; don’t anabolics tend to increase cancer risk?

The evidence is extremely varied, and in my opinion unreliable for making serious claims. Commonly cited by those repeating these claims, which as others have pointed out is rife with issues pertaining to causality, is the 2004 study "Ejaculation Frequency and Subsequent Risk of Prostate Cancer" published in the Journal of the American Medical Association (JAMA). Here is a section summarizing what came before: > Prev…

My wife and I have been trying for a kid for a while, and though I’m healthy, over the past 9 months I’ve gone down a rabbit hole on the professional literature around men’s health. I don’t know how it compares to anything else, but the variance of the data is what struck me the most. That, and the low-resolution around a lot of the studies that have been run. I get that science is hard, but I would expect a LOT more…

Hey man good luck! I know some people who have tried and tried before it finally all clicked. One person I can think of now has 4 kids! It can be tough. I'm sure you don't need any advice.

Kids are the best, most meaningful thing you will ever do. Its worth it to keep trying.

> It's your own responsibility to figure it out instead of being told what to do. Why bother having education system if you are supposed to figure everything out on your own? How is nutrition different from math or grammar?

"How is nutrition different from math or grammar?" Well, because 1 + 1 = 2, all the time, and the optimal diet is different for everyone?

Because 1 plus 1 is an optimal problem? You’re conflating apples and macronutrients. This is analogous to fake news.

What are your current diet assumptions? From what I heard, the best way to stay healthy is to follow mediterranean and DASH diets.

I am currently "researching", learning all this stuff. So I guess take it with lots of caution? Since you asked, this is headlines of most of what I figured out: * Your main goals should be achieving metabolic flexibility, eliminating most of the "bad" stuff (sugars, processed oils, most carbs, etc.), supplying your body with mitochondrial decouplers daily and doing low level aerobic exercise, consistently. * If you…

Wow, thank you for writing all this.

I was fat or at least struggling to maintain for most of my life.

I've essentially learned similar ideas over the past few years and have had great success

> One obvious correlation could be testosterone: higher testosterone leading to less prostate cancer. But the link between testosterone levels and ejaculation frequencys is causal https://pubmed.ncbi.nlm.nih.gov/12659241/ "The authors found that the fluctuations of testosterone levels from the 2nd to 5th day of abstinence were minimal. On the 7th day of abstinence, however, a clear peak of serum testosterone appeared…

Testosterone cycles many times a day though and is affected by many behaviors. I’m not sure a daily measure is adequate.

When I'm in the mood of reading a bunch of smug nerds pontificating and preaching, I click on any popsci or diet-related article on HN. Never fails to entertain. Nofap like many things has been turned into a brand, and even politicised to the point some idiots attack it saying it's far right ideology. On the other hand there are teenagers with serious porn-related issues that think nofap will turn them into superhuma…

It's not far-right, it's just religious folks. I grew up in the church, and while I didn't take it seriously, many of my friends in our religious school did. We were made to believe that masturbation was really not good for you, and neither was pornography, which might seem reasonable to some folks. However, when you step back and see humans as just some primates that learned math, well it seems kind of ridiculous to…

>It's not far-right, it's just religious folks

whenever groups of young men engage in sexual self-repression that almost always has a political component. And pay attention to the "men" part, because nofap is almost exclusively a male phenomenon. Religious sexual repression is not, if anything the opposite. Also religious sexual repression is compliance with religious law, not necessarily an act of voluntary discipline.

"nofap" in contrast is essentially an extremely online version of Fight Club, and the political undertones are pretty obvious. It's mostly disaffected guys deciding to undertake some Yukio Mishima-esque training to combat their low self-esteem.

I only ever heard cult used in the sense of an organised group that is lead to believe harmful and untrue things, but checking the dictionary, it can also just be "great devotion to [e.g., an] idea" (merriam webster) which could be said of nearly any subreddit. In what way do you mean it? Besides the correlation in this study, is there anything particularly harmful in the same way that a more stereotypical cult (KKK…

It is truly tiring to see all these "linked" articles. It might be interesting but without some more research it is useless and just messes up with 99.9% of population who will read it and wrongly assume sexual activity prevents cancer. I am currently on a big spree trying to fix my diet and sift true information from all those wrong inferences. Turns out, almost everything I have been told and red is a lie based on…

Makes me wonder about cholesterol. It is used in the brain, but we have had a generation on anti-cholesterol drugs with rising rates of dementia and Alzheimer's
