From Mad Gender Science!

I tried to find a citation for the "finasteride blocks types 2 and 3, causing upregulation of type 1, which causes bad stuff", and instead found this, which claims that finasteride blocks type 2 only (as contrasted with dutasteride, which blocks type 1 and 2). Really want some more citations here, looking into it now but might get distracted so I'm saving this note here --Conifer (talk) 18:49, 14 September 2019 (UTC)
