Statistics on ED resolution

Does anyone have any statistics of any kind about the percent likelihood of men who have ED resolve? For example, we’ve all seen that Northwestern study of about 12,000 individuals. It says something similar to:

“Among the men studied, 167 of 11,909 (1.4 percent) developed persistent erectile dysfunction (“PED”) that continued for a median of 1,348 days after stopping the drugs.”

Does anyone know what that really means? Does that mean that the median person had PED resolve after 3.7 years, or does that mean the median person had PED continuing and that person was merely 3.7 years off the drug? Example link:


Basically, wondering if there is anything out there - more macro data - in terms of facts or likelihood of PED resolution besides a bunch of individual or micro-level anecdotes.

What that means is that of the 1.4% of people they measured, the median score for how long ED lasted was 4 years.

And then…PED resolved after four years and so everyone here is “normal” again? Or, of the pool of people they are measuring, they’ve merely had ED persist for four years at the time of measurement? The language could be a lot clearer.

Kind of wondering what the “typical” person can expect based on the macro data to know if the likely move is to wait it out for four years…or if you’re just fucked and should start looking at something drastic like an implant if you want a somewhat normal quality of life.

Oh, I know this study. Why would it take 4 years though is the million dollar question.

I beleive it means that the average time of suffering ED among 167 studied pfs patients was 1348 days. That doesnt means it resolved at all. For example you can have 50 patients suffering for 2 years, 50 for 4 years and say 67 for 5 years so the average is close to 3,7 years… Studied patients were probably still suffering at the time study was done.


mean = the average number of a range of numbers
median = the middle number in that range
mode = the most common number among the range

The only thing this phrase is saying is that the 3.7 years (which is 1,348 days) is the middlemost number of days suffering ED among the range that goes from much less than 1348 up to more than 1348).
The KEY thing from this phrase is that ONLY 167 out of 11,909 men developed PERSISTENT ED. That is about 1%, a very small number. Which gives everyone hope.

Persistent ED is obviously not the same as temporary ED. Men who had temporary ED not persistent ED could be a very low percentage or a high percentage or something in between–we don’t know. But what we do know is that it went away, which also gives everyone hope.

Yea but we probably represnt that 1% of persisting ED in the study. Also, I dont think 1% is small number at all.

It is a small number in the study referenced above.
It may not be a small number, but we just don’t know. Even 1% of a large number is large, granted.
But it is better for us to keep things in context, not awful-ize things. That’s how we can cope.
