The Characteristics of the Transitional Zone in Prostate Growth With Age

These results suggest that transitional zone growth is the main contributor to total prostate growth, especially at the ages of 50-69, which may elucidate the higher incidence of the lower urinary tract symptoms from BPH. In view of the increasing rate of transitional zone and the level of total prostate volume, further research is needed to identify the underlying mechanism for such differences in prostate growth.
