Doppler results for testicular blood flow in male Shiba goats showing the changes in the resistive index (RI; A) and pulsatility index (PI; B) of the supratesticular artery after injection of GnRH or hCG. Results are presented by mean ± SEM. a, b Values are significantly different (P<0.05) compared with 0 hr in the GnRH and hCG groups, respectively. c Values are significantly different (P<0.05) between the groups at the indicated times during the study. (Note: the RI showed significant differences between the groups at 1 hr and 24 hr post injection without any significant difference between the groups in term of PI.)
