Fiber has nothing to do with testosterone levels.
Psyllium husk is a GREAT supplement to take.
[FONT=wf_segoe-ui_normal, Segoe UI, Segoe WP, Tahoma, Arial, sans-serif]Psyllium husk is the highest natural food source of soluble fibre you can obtain. The majority of the fibre you intake from your daily diet is insoluble fibre. The key benefit of soluble fibre is that soluble fibre absorbs water in your stomach and creates a gel. It gives your intestines a sort of 'internal scrubbing' as it passes through. It will help keep you regular and the faster you can remove toxins from your body, the less likely they are to be re-absorbed. [/FONT]
