Gyno from propecia only occurs in 2% of the men who take it for hairloss or prostate size. And its effects on libido are exaggerated.
I fundamentally disagree. It is my opinion from the numbers of Propecia users who end up here and elsewhere that Propecia is significantly associated with gynecomastia and I would not readily accept figures from Merk or other vested sources that suggest otherwise.
And as far as "permanent loss of libido," not only have I never seen evidence of such a claim, I have never seen evidence that even the mild/moderate reduction in libido by those who take it failed to reverse itself within a year after discontinuing use. I would appreciate proof to back up your claims.
Well Eugene Shippen who is the worlds leading expert in the area of male hormones and andrology totally disagrees with you and he goes further by stating that finasteride has been known to cause a very difficult to treat form of hypogonadism- with it often comes reduced libido. Given that finasteride reduces dihydrotestosterone and dihydrotestosterone is the most potent male hormone and required for libido and male performance- it is not remotely odd that libido is reduced.
Of course you can argue otherwise by using Merks figures in terms of what people have supposedly self reported- but how many men will go to their gps and raise such an issue?
The fact is there are many men out there annonymously complaining of these effects and lowered libido actually reported as indicated by Merk and studies is merely the tip of the iceberg.
I offer you one case of such and a link to a website that has been put together by people adversely affected by finasteride- Propecia and otherwise.
When there is an entire worldwide community associated with side effects of a given medication it is time to wake up and smell the coffee.
On a personal note I have known as many people end up on this website complaining of gynecomastia following the use of finasteride based products as I have anabolic steroids. If this site is remotely representative of the associations then propecia is strongly associated with the development of gynecomastia.
For the last two years there has been a non stop steady stream of those that have ended up here due to propecia/finasteride use- some of these people have also complained of reduced libido.
But here is some of that evidence you wanted.
An individuals case and that of many, many others.
