Penile Shrinkage Question

I’ve now been off fin for 4 1/2 months. The concern I have is that of penile shrinkage. At times I get the sense that it has reduced in size but I have no way of knowing for sure. It’s more just a potential feeling or maybe even just a fear. I am not sure but it bothers me to think that my 3 years on fin would of caused shrinkage.

Questions:

(a) for those of have definitely experiences penile shrinkage how did you know for sure? How long were you on the medication.

(b) does anyone know or can explain the science behind how the drug shrinks the penis?

thanks in advance for the support.

There are two kind of shrinkage. One is related to the loss of weight of the penis. This cannot be documented. At most you can have an dynamic ultrasound of the penis to state if in the process you had fibrosis. There is a study on rats however, documenting the loss of penis weight in just some weeks.

There is also a shrinkage due to a contraction of the penis because of the lack of relaxant and anticonvulsive neurosteroids.

thx. Can you expand this further, ‘lack of relaxant and anticonvulsive neurosteroids.’?

I’m just trying to uncover whether my concern is absurd or may have some valid.

I don’t recall reading this, do you have papers which state neurosteroids control such aspects of penile hemodynamics, vasoconstriction etc?

To the OP – review the sticky posts in this subforum and you will note that men suffer smaller penises after radical prostatectomy. One of the main actions of Finasteride is to atrophy the prostate, nearing the point of chemical castration as evidenced here: viewtopic.php?f=8&t=1402

Additionally, penile tissue is rife with 5AR2/androgen receptors (where DHT was inhibited by Finasteride) and androgen is necessary to maintain proper penile health, vascularity, erectile function etc.

Considering the drug is a form of androgen deprivation on such tissues, it is plausible that structural changes could occur. Although, for many the shrinkage tends to occur post drug, if they experience a big drop in Testosterone within weeks of quitting, usually quite rapidly due to this process.








The good news is shrinkage seems to reverse itself in those that recover. Stay positive!

Mew has got some really good texts. I like how the figure demonstrates how dynamical the penile tissue is. It suggests that once you get your androgens back functioning the tissue starts to recover and remodel back to normal.

I didn’t mean that neurosteroids act locally as pro-erectogenic molecules. I meant that the imbalances of the neurosteroids on the CNS (for sure but possibly also in the PNS) may lead to nerve dysfunction/neuropathy, and since the penis is nerve dependant (hemodynamics is in particular), it may be affected too. Considering the effect of finasteride is on the androgen dependant zones, it is much probable it has been affected.
Tough the fact that the shrikage is driven by some kind of nervous dysfunction (like dysautonomia or nerve damage) is my assumption based on the various neurological diagnosis and on my experience with the shrinkage, HF, and a strong hardening of the penis while in the midway between flaccid and erect. These three conditions feel exactly the same so I do call them all HF. The timing involved in HF is too short to be hormonally driven. If it was hormonally driven, one should observe a gradual hardening, which is not the case: HF comes suddenly in an unnoticable timeframe. And leaves in the same way. Which is the nervous dysfunction behind this is surely questionable. It might be that low neurosteroids prevent the healing of the nerves, or it might be that they are the cause of nerve dysfunction by causing nerves to get damaged (by biochemical or by mechanical influence from the surroundings) or by imapaired signaling. I don’t know. But there is enough science to question exactly the nervous phenomenology induce by those reduced neurosteroids.
As an example I have been diagnosed by coincidence with sympathetic nervous system hypertone. I saw similar diagnosis of hypertone. Also, as you surely know the penis is also dependant on sympathetic and parasympathetic stimuli. Consider in all this, that HF is not even recognized as a reality.




Well I definitely had shrinkage. I know not only visually but also by direct measurement. Yes I measured in the days prior to Propecia (I know there are other members that share this indiscretion :wink: ). I lost about a half an inch in length and noticeably more in girth. More pencil-like now. I lost morning erections sometime ago and for a while complete penis-brain disconnection so I couldn’t even get movement in the penis with kegel exercises. I attained those after about three months. I have had only a few morning erections over the last one year but they were not stiff (though I became thrilled thinking my nightmare was over). I agree that the loss of size is restorable. It is in fact due to the loss of erections and thus engorgement of the erectile tissues. My urologist told me that he has seen a lot of shrinkage over the last 20 years with men on Proscar and those who have had prostate surgery/resection (Propecia shrinks the prostate down to a tiny piece of tissue). So he didn’t reassure me or say it is in my head. The penis is still rubbery in feeling but I am hopeful if I ever get function back that the penis will also get back to normal size.

Can any long term PFS victims with severe sexual side effects please report on any improvements you have seen in terms of sexual function or improvement to shrinkage.

I’m approaching 11 months off but still impotent with very severe thinned penis.

Please advise.

Also, has anybody who lost length and girth, can you state if this ever got better?

My penis is so fucking thin since taking this bull shit!!!

I haven’t logged into this site for a long time, but would like to give my input.

I also had measured before propecia usage and can confidently say that my penis circumference went from 5.5" to 4.25" over the course of usage which was 18 months. Length went from ~7" to 6.5" I got off propecia in May 2008, and since then my circumference has improved to 4 3/4 at the absolute most. I stress absolute most because I had to work to improve it, although time helped as well. However, this is still very significant and I expect it will improve over time, but only assuming I diligently work at it (which I haven’t always, due to various lifestyle changes over the past several years).

One thing that undeniably helps that I really wish I had done earlier is take a PED at night, regularly. Some people here are worried about doing this because of a tolerance build-up, and want to “save them for when they really need it.” This is ridiculous to me; you need it as soon as you start showing symptoms. Your penis will progressively deteriorate if it is never supplied with bloodflow and the nutrients this brings. START NOW. To mitigate tolerance, take them every other day or less, and/or rotate different meds. Over time I have come to prefer cialis simply because it lasts longer. Price is a poor excuse as well; I’m poor and can get them off various online pharmacies without breaking the bank. Hell, taking it once a month is better than none, absolutely. Yes it is not as safe as regulated pharmaceuticals, but how bad do you want to improve? For the record, I’ve never had any problems with my purchases.

I also used a medical grade vacuum pump. Religious usage helped, but only slightly (like 1/8" over several months of near daily usage). I lost my pump during a move, and probably won’t get another one, but I still recommend it because it only helps when used properly, and the act of having some control over the situation made me feel much much better. It also significantly improved my brain-penis connection, and looked and felt much much healthier. More info on pumps can be found at peyroniesforum.net.

The reason I won’t get another pump is because I’ve found something I prefer, which is clamping. Clamping is a penile enlargement technique I learned at thundersplace.org. It’s not as scary as it sounds, and after a good session I’ve noticed a 1/8-1/4" improvement immediately, and believe this will improve over time. It’s free and improves general penile health and feeling noticeably. When combined with nocturnal PED, at times I can feel pretty damn close to normal, and my penis size doesn’t keep me from pursuing sexual relations even though I’m not really that close to my pre-fin size.

Other things I’ve tried over the years that may have slightly helped are quercitin and l-arginine. I wouldn’t expect too much though.

All these techniques, along with time, have improved my situation physically and mentally. I don’t avoid all sexual situations just because of my penis size anymore. My mind-penis connection has improved tremendously. I expect more improvement over time. There are fluctuations though, don’t expect linear progress.

Other comments: I’ve been off about 5 years after 18 months on. I never had a crash, mine was more very slow, almost imperceptible deterioration. Over time people treat “the crash” as if it’s gospel on this forum, but I think this is misleading, as I and others didn’t experience such a clear crash when coming off the drug. I deteriorated slowly while on, and have improved very very slowly since coming off.

This is all I can think of for now, good luck.

i lost some girth. when flaccid the skin wrinkles. been 2yrs now since that regretful day. the girth did not return i just cant tell. i really forgot how my penis looks like before fin.

I’ve had shrinkage in the testicles but my penis actually got bigger and is now starting to bend.

Can anyone explain how fin made it bigger ?

Also my penis flaccid wont go back to its original size its like its semi erect all the time.

IMO i dont think it made your penis bigger. you have testicle shrinkage so it gives you an illusion of bigger penis.

No its definitely a lot wider and slightly longer I had this side effect after I crashed this was before my testicles shrank.

While it is bigger it looks and feels like its half dead.
