No, I am not. I am trying to understand what causal theory you are trying to prove with the research? Do you have a causal theory as I described above?
Thanks for having some faith in our good intentions. 
The theory is laid-out in awor’s “5-ari-Withdrawal Syndrome” paper and supported by Melcagni’s research showing lowered neurosteroid levels in PFS patients and Di-Loreto’s study showing persistent upregulation of AR in penile tissue of PFS patients.
AFAIK, Baylor may bridge the gap between drug and symptoms if they find androgen-responsive genes are being aberrantly expressed in PFS patients.
It would be nice if someone could write up a summary of the causal theory in laymens terms (much simpler than what axo did above, with more definitions etc). Also what are the gaps in the causal explanation chain? What results would dissprove the theory? Like 6 year old terms. If you had to explain it to a patient who is illiterate with medical terms etc.
So if Baylor is a nothingburger the theory can be laid to rest? After all awor helped design it.

It would be nice to have a graphical representation of the theory made for the purpose of explaining it. Picture is worth a thousand words. Unfortunately, the admin/mod team is so inundated in regards to our volunteer work, professional lives, and personal lives, this will not likely happen soon. Generally speaking, we are like anyone else here dealing with keeping it together while suffering.
The hypothesis wouldn’t necessarily need to be abandoned if Baylor publishes no significant results. The hypothesis may be modified to exclude what Baylor was specifically investigating.

I suppose Baylor, if it supports the theory will simply add to the ammunition. Upregulation of AR is already proven. Causality will be harder to prove though it would be highly unlikely if it weren’t causal. I’m not entirely sure what Baylor will add in terms of utility other than highlighting which epigenetic changes have taken place… and perhaps trying to find the modification which may lead to excessive AR expression.
Hey guys, this topic was only to briefly explain what is meant by methylation, which has been proven and reported site specifically in PFS patients already. Theories are therefore not relevant to the content here as this is just a basic mechanism of cellular biology. This ties into a broader framework most users don’t have, so therefore might be handy as it’s unlikely the last you’ll hear of it.
Regarding theories, the microbiome is almost certainly disturbed in PFS as both ADT and tissue AR dysregulation is proven to do so. I’ve linked to a study regarding this some time ago that I believe you recently posted. That is therefore supported by evidence as a plausible consequence, of which there are many, and is not a site-specific cellular mechanism nor is it capable of causing what we have seen for the past fifteen years.
@pvdl, as I’ve said we’re working on a project that should hopefully answer all your questions, but it’s taking some time as it has to be robust and comprehensive. There’s a lot to cover and it is simply not suitable for a forum post format. There’s a lot of recent science we haven’t discussed (as I’m considering submission to peer review) that we feel very significantly ties into the bigger picture. And whether you find it hard to believe or not, many of the most severely affected members took one pill or less. This includes myself. While a single epidemiological study of 5ari use in general found length of use of 5ari to increase risk of lasting erectile dysfunction, every single study of PFS that profiled symptoms with validated and as hoc instruments concluded that severity had no correlation to exposure in their samples. The entire reality of a post drug syndrome is out of the realms of what makes “common sense”, so I find it quite incredulous when people with at least some degree of lasting effects start picking at other members because to them it seems rather far fetched to them. Your case does not seem any less far fetched to the millions on this drug with no significant detrimental consequence to their quality of life, otherwise your doctor would be up in arms and no one would take it. It’s important to bear in mind there is obviously something different about susceptible patients, and significant variation within that. Many years ago Crisler phrased it as there being something about our endocrine systems that “is all set up to get broken” when he was explaining that he was repeatedly seeing patients with PFS who did not respond to treatment, and in layman’s terms that’s the long short of it. Precision medicine study by Cauci et al already correlated both exposure and PFS symptoms/severity to AR polymorphisms, so the “something” I mention is likely to be genomic, epigenomic or both. That’s why we’re taking a look at what we can ourselves with the 23andme project. It’s a serious long shot, but it’s worthwhile in the meantime.
Let’s keep this topic on track now as others can be started regarding unrelated stuff or theories.

Looking forward to it. I would suggest that it’s incredibly important that a detailed summary is posted on propeciahelp, explaining the causal theory you guys are working with in Layman’s terms, so that even the average visitor to this site, who is not immersed in the scientific literature and doesn’t understand even basic medical terms, can understand it.
I. E. Finasteride intake causes A which causes B which causes C which causes D which causes symptoms, in person susceptible to PFS. Our research is focused on proving out step b to c for example or filling in following blank. Pls donate to this current study to achieve this. And then a link. As suggested above this page could be enriched with nice visuals. It could also list outcomes that would disprove the theory etc.
Pls no correlation in correlation out stuff.
I need to clarify a few things real quick.
First when I use the terms believe or hard to buy into, I was talking about permanent changes in human dna from one pill. I wasn’t talking about being affected from just one pill, Im not questioning that.
Also when talking about methylation, I think this could still fall into the realm of Gut homeostasis.
On the microbiome I think I could challenge this thought based on my own experience,
But this is coming from Accutane not Fin (maybe more of a one trick pony where its very easy to zero in on hormones)
Accutane can change the expression of literally hundreds of genes.There’s also probably alot more wide ranging studies on Accutane and even retinoic acid itself then Finasteride to come to different conclusions or have different thoughts.
Accutane has been shown to have powerful immunomodulatory, antibiotic, and hormonal properties as part of its mechanism of action. As far as a 5ar inhibitor (or hormonal), I thought this effect was rather weak compared to the others just mentioned.
Anyways to post another thought back on topic, just because we haven’t been able to treat this yet, doesn’t mean it might not play a major role.

I have a question if I may and if someone does have a time/mood to answer - why do some sufferers clearly purely benefit from methylation/taking methyl agents (even some recoveries), while others from demethylation (this makes sense)? Sorry for spamming if it is explained here, I already guess it has been answered, but those large blocks of text are sometimes overwhealming for my congnition, even more after a hard day… and thanks in advance
My guess is because not everyone gets the same genetic alterations. Maybe for some, silencing of genes is the main problem, where for others overexpression of genetics is causing the struggle. This is just a thought tough.
Thanks for the reply, but I kind of thought it may be like that, but still doesnt make much sense to me… shouldnt the syndrome causing meds be having more or less same mechanism of action on everybody? Either silencing genes or somehow overexpressing them? Probably (dull) question for the more knowledgable on this forum, but still interesting and important for the less knowledgable
By the way, I for long wanted to do some gene testing like MTHFR, is it useful in practice? Will it somehow help me to know if I should avoid x, y, z or do x, y, z - or is the test kind of waste of money in regards to the syndrome and its treatment? Will it be useful to this whole methylation/demethylation issue on personal level - for me to know the results, help in treatment itself? Prevent crashes (ok, I am taking this too far… :D)? Thanks for insights in advance
Personally, it’s all fine with me. Epigenetic damages or not, gene methylation or not, BHB, Keto and fasting helping or not.
I get that our DNA is rolled up in every cells as a compressed file on a computer, with only a few segments unrolled so that the cell can use them and that’s what epigenetic is about. Otherwise it would be unpractical and would probably mean death.
I’m less active on the blog because I don’t have much symptoms left after 13 months of carnivore / ketogenic diet (or at least that’s what I attribute it to with an almost certainty) and I feel better than I did in the last 20 years.
I’m a company owner, there’s a HUGE financial crash coming within 2 years, one that will dwarf the 1929 depression and I will most likely lose my factory. Having 3 kids and a wife and living in a foreign country with no security net, I’m now spending all my time studying economics and finances and trading on forex and stock markets.
I believe the Universe is alive and that it interacts with us, especially when it’s important and we pay attention. I asked the Universe for a remedy to my crippling pfs and coincidences after coincidences, I ended up with a strict carnivore / keto diet and weight lifting. 13 months later, I’m better than pre-fin.
So this is the kind of guy you’re dealing with when you address me. If you don’t believe in that kind of shit, by all means, just dismiss me and ignore the few posts I’m writing. There’s actually science behind my “Universe is alive” claims but here is not the place to debate this and frankly, from my point of view, it changes nothing what you believe in (except for feeling sad for those who believe (and it is a belief) the universe is dead and things happen randomly. I can’t imagine the feeling of loneliness and isolation that belief would bring but it’s not my place to judge).
I’m not pushing any ideas on anyone, just sharing honestly what I believe in, mostly with regards to fighting pfs. It’s up to each of you to integrate or dismiss what you see fit or unfit. But I do wish you all the best and I hope sometime soon, we’ll find a way to counteract the damage done by those drugs.

Thanks Ozeph for a very nice post. And couple things related to this condition brought me to the rock bottom in many ways and I even did multiple Ayahuasca treatments and believe me when I say that I know EXACTLY what You mean, it changed me to much better person - for good. Universe IS alive. Thanks for Your kind wishes and I wish You the same and good luck also in upcoming financial crisis, hopefully it will turn out good for You and family anyway somehow. Good luck and strong health Ozeph

Hey by any chance did you take the pill on an empty stomach?
Hey,
I’ve read a couple of posters on here saying it may be hypomethylation instead of hypermethylation. I read most of what I read on here with a grain of salt. But would also like to know if there’s any validity to this point. I also noticed you mentioned a couple of other regulatory mechanisms. Is there a reason why methylation is the one we’re focusing on over others. Sorry just trying to catch up.

Isn’t it more likely for a function to be silenced due to the necessary gene being methylated rather than a gene that prevents the function being hypomethylated (this is how it seems intuitively but it could be wrong). Also the fact that many people have crashed by taking methyl donors gives us evidence to believe that methylation is the problem.

Hi,
In biological systems, it happens that an inhibitor is synthesized from gene 1 to silence/repress the expression of gene 2.
This hypothesis is possible, as well.

So, this process has nothing to do with methylation?
Not sure hence my confusion. Methylation treatments have also made things worse for some people though I guess.
A study (Melcangi’s I think) has shown methylation of AR promoter in some tissues. But still it’s not sure yet if this is the cause or the consequence. What I am telling you here is very inaccurate. Just a general idea.
