TLDR Finasteride may cause lasting sexual side effects, but more research is needed.
The article discusses a study by Irwig that reported persistent sexual side effects of finasteride in 96% of patients despite discontinuation of the medication. The study recruited most subjects from an internet forum, and the correlation between finasteride and sexual dysfunction is not consistent with other large-scale studies. The authors of the article suggest that more consideration of the study's methodology is needed before interpreting the results into daily practice or medical education.
