Can we please have a conversation going back to the basics? WE SHOULD SUPPORT PFS RESEARCH to speed up things, but I hope we can try to have some conversations on the issue on our side too. I believe this is as important. FYI I am a researcher but in another field (if that helps my credibility at all, have a PhD and I am a mature and very sensible guy so please hear me out …)
I just heard the interview with Dr Yu which is key, because it goes back to the basics. They discuss the up regulation of receptors. My first reaction was similar to Dr Yu, the causality could (most likely) be from low androgen to up-regulation. That is she seems to think that our symptoms might not (most likely) be due to an up-regulation. For example, they could be due to lower androgen reaching these organs (something my Doctor said, they can just test circulating) or due to some aging of the ograns (which would be a disaster), or a lot of other possibilities.
I have an important observation to add. The lack of libido, the loss of sensitivity, and ED are not special to 5alpha-reductase inhibition I think they can be caused by any form of lower andorgens/DHT either directly or indirectly. I say this because someone I know got THE EXACT symptoms after being on an anti-androgen. He never touched Finasteride, SP, or other. I think that helps narrow down the mysterious channels. While the inhibition of 5 alpha reductase could be the direct cause of a lot of the mental issues, our sexual symptoms, including this weird numbness and changes in texture are most likely due to androgen deprivation. He also recounts a story of him crashing after stopping the treatment.
So that is one thing we all have in common. The way it happened to me is that when I stopped Fin, I had two weeks of VERY high libido, I was ejaculating every day which I have not done in years, for almost 10 days in a row. Then came the crash.
So androgen increases but receptors are still up-regulated due to a lag, this is the feedback loop story. And then what? Million dollar question – what causes the crash…
Here is another important observation: A lot of us become EXTREMELY sensitive to any form of androgen deprivation. Case in point, yesterday I applied Eucapil to my hair, this is a topical agent that is supposed to bind to the androgen receptor ONLY topically (I will double check the details) and I suddenly felt like crap, numbness increased, libido dropped from 0.5 to 0. I have used it for years, sometime 4 capsules at a time, this is a drug that is marketed as having ZERO systemic effect because of the way they deliver it, it gets converted to basically water in the blood. All this to say very small decline in androgen or in functioning androgen receptors leads to a big effect on us. This has zero effect on a healthy patient.
