KEY WORDS:

SUMMARY:

This experiment was conducted in three stages, so that data were obtained from different areas. First, data collection was performed in the field, with a complete clinical and andrological examination, ultrasound evaluation, and sample collection; these collected samples were then processed in the laboratory (laboratory evaluations of semen) and, finally, image evaluations and treatments were performed in order to observe the ultrasound image data. Ultrasound evaluations were performed on all animals that participated in the experiment. For this purpose, a transducer was positioned caudally in the most ventral portion of the spermatic cord, in a longitudinal position (Batissaco et al., 2014). The spermatic cords of the left and right antimeres were evaluated following the same technical procedure. All images were generated with the same configuration (Frequency Doppler (4.5 MHz), gain (88%), pulse repetition frequency (PRF 8 KHz), depth (1 mm) and wall filter (WF; 2 Hz) and following the same processing protocol; the variables that were analyzed are the vascular indices: resistance index (RI), pulsatility index (PI), systolic and diastolic peak velocity (Vs and Vd) and velocity time integral (VTI).
