International Index of Erectile Function (IIEF) Results

This table shows the survey response data for the IIEF questionnaire, which is a scientifically validated instrument. The table is quite large. If you want to study the data more in detail, you can download it by pressing on the down arrow symbol at the bottom of the chart.

The reference values are as follows:

At the time of writing this post, our results before the drug are somewhat better than the controls in the referenced study. This may be because on average, our cases are likely younger than the typical erectile dysfunction patient (would need to check the full text of the study). In any case, what these results definitely put to rest, is that PFS patients may have been suffering from sexual dysfunction before taking the drug, an argument that naysayers and some doctors have been using for years.

The following chart shows that, once again, all three main drug categories are causing a similar level of sexual dysfunction (results post drug):

Comparing overall figures with results from study cited below shows the following:

  • Survey participants closely match controls except for desire (see age related comment earlier). This validates our data, i.e. makes it difficult to brush off.
  • Our data shows a clear worsening between on drug and off drug for all involved drugs. This post-drug worsening is a unique characteristic of our syndrome and gives credence to the hypothesis that they are linked.
  • The study participant are less severely affected in the erectile dysfunction and orgasmic function domain than the participants in the Rosen paper (see below).
  • Our study participants are more severely affected in the desire and satisfaction domains than the Rosen participants.

Is it statistically significant?

The most striking thing is that our PostDrug erectile function is better than the Rosen group (teal) but sexual desire is worse.

Survey participants closely match controls except for desire (see age related comment earlier). This validates our data, i.e. makes it difficult to brush off.

For clarity - you mean Before Drug scores closely match controls? Controls meaning unaffected, healthy individuals.
