Glad to see people aren't even reading the study and making uninformed statements.
https://peerj.com/articles/3020/
"Of 4,284 young men exposed to finasteride ≤1.25 mg/day, and without prior sexual dysfunction and who were evaluated for new PED, 34 (0.79%) developed PED (median 1,534 days after stopping 5α-RI, IQR 651–2,351 days)."
Out of over 4,000 subjects sampled, 0.79% of young men taking <= 1.25mg finasteride reported persistent sides. That number is literally statistically insignificant. By statistically insignificant, I mean that figure is so low that even a 1% sampling error means that literally ZERO occurrences of persistent ED is equally likely to 1.79% rate of persistent ED (which is still very low).
If anything, this serves as evidence that there's no proof to conclude whether finasteride can even cause persistent ED. This is also based off the narratives of subjects. It's not a new study. They're just sampling existing data. The 1.2% figure lumps together ALL finasteride and dutasteride users at ALL dosages so that number is even more useless.
Come on people. Do a little more due diligence before making blanket claims.
