Hi all, I think the answer has been all around us, yet we just haven’t put it together yet, but let me do this for you guys.
First of all, I know I’m new to this forum, but I have been lurking for months due to my own issue. I won’t go into detail about it, but please read what I have put together before judging, as it is not based on my words, but actually backed by science, and well, some anecdotal evidence.
First of all,
1.Finasteride upregulates androgen receptors to the point that it may actually become so sensitive to testosterone that it shuts down.
With a greater concentration of receptors, the [penis] becomes more sensitive to testosterone and at a certain point, paradoxically, that sensitivity may shut down.
A group of Italian researchers gave finasteride to rats and noticed that the number of androgen receptors in their brains went up. Moreover, the effects persisted long after the drug had been discontinued.…[T]hey then called in men with PFS, took skin from the penis and found that the density of androgen receptors in men with PFS was about twice that of those without. Now, remember the idea of the testosterone bell curve and damping effects (little testosterone, little growth, more testosterone, more growth, even more testosterone, reduced growth)? I think this is what we are seeing here. With a greater concentration of receptors, the organ becomes more sensitive to testosterone and at a certain point, paradoxically, that sensitivity may shut down.

I then discovered this article https://www.longdom.org/open-access/postfinasteride-syndrome-about-2-cases-and-review-of-the-literature-2472-1212-1000170.pdf
**In this article, case 2 a TLDR is that the subject had experienced sexual side effects, penile insensitivity, libido, and ED issues. Androgen receptor was found to have lower sensitive (due to over expression). Subject was treated with anastronzole for 2 weeks, and started seeing improvements **
A DHT measurement was performed, as well as a genetic analysis of CAG triplet repeats of the androgen receptor gene, since polymorphisms at this level could be associated to its lower sensitivity to androgens. DHT resulted in a value of 192 pg/ml (112-955 pg/ml), interpreted as a low DHT for his age. CAG determination resulted in 24 repetitions, interpreted as significant for lower sensitivity of the androgen receptor. after this evaluation, the indicated treatment consisted of HCGu 6000 UI/week, divided into 3 applications of 2000 UI/week, combined with Anastrozole 2 mg/week, divided into 2 intakes of 1 mg/week.

In another topic in this forum, another user posted a theory of why PFS happens. In @skorpia88’s own words
1.Some guys get PFS while they’re taking propecia without having any kind of crash which precipitates the onset of PFS. This can be explained by the fact that maybe guys who experience this had a high density of androgen receptors to begin with; therefore the usage of propecia upregulating their androgen receptors even more was the proverbial straw that broke the camels back and caused the body to freak out and silence the androgen receptors when it sensed that there were too many receptors
Then according to him:
With that being said, I think that the way to treat PFS involves two things:
1.you must downregulate the androgen receptors
2.you must resensitize the androgen receptors
Another user named DHT, then said in the same post
Yes i was also thinking about restarting high dose finasteride for reducing the impact of over-expressed AR`s but currently i am testing with changing Estrogen / Testosterone / DHT ratio by taking out estrogen my libido came back immediately to my pre pfs hyper-sexual level then it went down a little bit but did not diminished.
I think my reaction was like secession of Finasteride i flooded my body with androgens and it adjusted with reducing sensitivity.
Some of our brothers committed suicide after testing this some of us get better i consider my self to be lucky for now.

> Then i researched and find you and started arimidex that was my first real reversal after 8 years.
TLDR, a user named DHT used arimidex and started seeing a reversal. Arimidex is basically the brand name of Anastrozole, which the doctor from the case study used in combination with DHT therapy to treat the PFS issue of the patient
Basically, for those with penile issues/erectile dysfunction/ low libido, I believe we need to downregulate the androgen receptors and resensitize them. Our normal blood work will not tell us there is an overly expressed androgen receptor. This is why sometimes our bloodwork may appear to be normal, or that testosterone therapy doesn’t work. I think we do need to fix our androgen receptors first
