“…In the current study, values of the Doppler indices of the STA were notably greater than those reported in Bos taurus bulls in previous literature [35,36]. These differences might be attributable to the anatomical characteristic differences between the scrotum in buffalo and Bos taurus bulls.…”

“…This result corroborates the ndings of Kowalski et . This difference might be related to the age of the animals in the cited studies since pixel intensity of the testicular parenchyma is higher before and during puberty (Brito et al, 2004;Rodrigues et al, 2020).…”

“…Ultrasonography is a complementary technique to andrological examination and can be an excellent tool to examine the integrity of the testicular parenchyma, in addition to being a rapid and non-invasive method. Spectral Doppler ultrasound can be used to assess blood ow indices in the testicular arteries and pampiniform plexus and thus to estimate blood perfusion in this region (Ortiz- Rodrigues et al, 2017;Claus et al 2019;Rodrigues et al, 2020). Studies have evaluated the relationship of these parameters with the semen quality of various species based on the testicular health of individuals (Pinggera et al, 2008;Ahmadi et al, 2013;Tomlinson et al, 2017;Camela et al, 2019;Gloria et al, 2018;.…”

“…In fact, Junior et al (2018) compared Doppler values of STA blood flow pattern in different breeds of bulls, the study found differences of the mean velocity, PI and RI between Aberdeen Angus, Bradford, Brangus, Hereford and Nelore bulls [27]. In another study performed in Nelore and Caracu bulls, significant differences between RI and PI where also found, meaning biometric ultrasonography characteristics of the testicular artery are affected by the genetic group [29]. The size of the animal also affects Doppler velocimetric parameters.…”

“…Pozor and McDonnel (2004) concluded it is possible to characterize the testicular artery by ultrasonography and the importance of its measurement in two locations due to its convoluted course [20]. Following these results, more research was performed in other animal species, establishing physiological parameters of the testicular artery using CD and SD at different locations in stallions [20][21][22], jackass [23], dogs [21,24,25], felines [26], bull [27][28][29], rams [30][31][32][33][34], bucks [9,12] and camelids [35].…”
