This study is fucked, to put it bluntly. They're lumping together Fin and Dut and people taking 5mg Fin. Most people taking Fin for MPB take 1mg Fin, for example.<p>You can actually not draw any conclusions from this paper other than, don't use Dutesteride unless you're male to female transitioning and don't go above 1.25mg finasteride if you want to keep your hair and your dick.<p>But it just confounds everything together, it's a terrible study.
> Among men 16–42 years old and exposed to finasteride ≤1.25 mg/day, 34 of 4,284 (0.8%) developed PED (persistence median 1,534 days, IQR 651–2,351 days); the multivariable model predicting PED had one variable: duration of 5α-RI exposure<p>So less than 1% of finasteride users get PED. PED was already a known side effect. That's good it's being confirmed with data, but aren't the odds still very low that this would happen to fin users? As a fin user myself, I haven't experienced any of the sexual sides so I'm wondering if there's any new take-away from this.<p>When I look at this as a fin user, I'm personally happy to see that the data says its so unlikely.
