Today, Saw Palmetto is more commonly used to treat enlarged prostate, in the early stages especially. It can be more effectively used in men who are over the age of 40 in improving prostate health. Studies have shown that for men who have benign prostatic hypertrophy, Saw Palmetto is especially beneficial. It will inhibit DHT (dihydrotestosterone) formation by effecting 5-alpha-redctase activities. While Saw Palmetto is an effective treatment for the serious health concerns associated with prostate problems, it has been recognized as being beneficial for men taking testosterone -boosting supplements.
For control versus finasteride-treated men, the tissue androgen values obtained with needle biopsy specimens were similar-both for absolute values and the percentage of change-to those previously reported using surgically excised volumes of prostatic tissue. The quantification of prostatic androgens by assay of needle biopsies is thus feasible and offers the possibility of serial studies in individual patients. The SPHB-induced suppression of prostatic DHT levels, modest but significant in a randomized trial, lends an element of support to the hypothesis that inhibition of the enzyme 5-alpha reductase is a mechanism of action of this substance.
