Résumé
The present detailed study aimed to establish for the first time reference values for ultrasound measures of testicular dimensions and Doppler measures of blood flow in the testicular artery of rams over a 12-month period, and to investigate a possible association between monthly changes in dynamics of testicular blood flow from one hand and testicular volume, plasma testosterone and estradiol -17β concentrations as well as semen characteristics from the other hand. Five fat-tailed rams weighing 45-60 kg and aging 2-4 years old were subjected to semen collection, jugular blood sampling, ultrasonographic scanning of the testes and Doppler examination of testicular artery twice monthly for a period of one year. The overall mean (±SD) values for testicular volume as well as RI (resistive index) and PI (pulsatility index), respectively were 71.84 ± 5.33 mm
