AR was seen more highly expressed in BPH + Ginkgo + Ex group (Figure 5), while the 5α-reductase in all groups remaining at comparable levels, a fact evidently suggesting that exercise and Ginkgo + Ex probably were only capable of enhancing the activity but incapable of affecting the quantity of 5α-reductase (Figure 4(c)). Here, AR is linked to benign prostatic hyperplasia.
