testosterone is different from hyrocortisone ,hydrocortisone is a corticosteroid and affects the adrenal glads,via the hypothalamus and pituitary but the oral or injected testosterone used for body building is anabolic type which will shut down the bodies testosterone production but the testicles will resume production ,(even worst case) could take up to a year but usualy about 4 to 5 months .in that case taking a raw testicle or(orchid) glandular (moderate dose) will reverse most of the damage and help speed up the process and taking 50 mg zinc daily will increase testosterone production once it has started again
