OK this study supports my suspicion that Androgens can cause a negative feedback leading to decreased activity of 5ar in the Brain. This study found that testosterone given to male rats decreased activity of 5ar in the Pituitary, I really hope i'm interpreting this correctly.
Regulation of the pituitary 5 alpha-reductase activity by gonadotropin releasing hormone and testosterone in the adult male rat. - PubMed - NCBI
@haidut I'd like your thoughts on this
You increase androgens peripherally puts a negative feedback on the Hypothalamus and Pituitary. Leads to decreased activity of an ALEADY SEVERELY DOWNREGULATED ENZYME IN THE PITUITARY. I'll add that this can explain why men report to get better on a low dose of Fin. Fin doesn't inhibit 5ar1 which is expressed in the brain. Fin reduces blood levels of androgens, increases 5ar1 activity in the pituitary
