a. Mean MAP (mmHg) before, during and after lidocaine injection and castration. The three curves illustrate the control group where no lidocaine was administered, the funiculus group where lidocaine was injected into the funiculus spermaticus and the testis group where intratesticular lidocaine was used. b. Mean pulse rate (beats/minute) before, during and after lidocaine injection and castration. The three curves illustrate the control group where no lidocaine was administered, the funiculus group where lidocaine was injected into the funiculus spermaticus and the testis group where intratesticular lidocaine was used.
