5 beta reductase makes your bile acids, without bile acids you will have a build up of cholesterol and malabsorption of fats. and mainly phospholipids and you will have bilirubin stones in your gallbladder which completely blocks all your bile flow.
this will cause deficiency of lipids needed for the brain , sex, fat soluble vitamins etc and you will have very thick blood since cholesterol wont be used and wont be disposed off.
This is why I said to do liver flushes all the time. Also you can take bile acids. chenodeoxycholic acid plus cholic acid. 5 beta reductase makes those . These 2 acids will dilute all your stones and let you absorb all the needed lipids from the diet. After years of fin your gallbladder had zero bile acids, means it is solid green mass with very little bile.
Also you need to eat good fats( butter) , plus vitamin Bs, since b vitamins make NADPH and NADP those are needed for 5 alpha and 5 beta reductases. Also you can add vitamin C , since cholesterol is converted down the line into 5 beta reductases by vitamin C and NADPH which fin impairs.

And vitamin B vitamins plus vitamin C
Plus flush the liver over and over again. This is the problem in PFS
PLus do the hairtest and see which other cofactors for bile you are missing like copper manganese zinc. etc
