increased in aged male rats when treated by taurine, while it were obviously
decreased by b-alanine supplement. The levels of FSH and E2 had no changes in all
the experimental groups.

32.3.3 Penis NOS and NO Analysis

The effect of taurine on the levels of NOS and NO in the penis tissue of aged male
rats was presented in Fig. 32.6 . The levels of NOS and NO were significantly
elevated by taurine administration. The NO level in the penis was obviously
decreased by b-alanine treatment in aged male rats, but the ability of NOS had no
difference with control group.
