Universidad de Zaragoza (orcid)0000-0002-7857-9732 Correlation of prostatic artery blood flow assessed by doppler ultrasonography with semen characteristics in beagle dogs 2020 Access copy available to the general public Unrestricted Pulsed-wave Doppler ultrasonography (PwD) is a method used to rapidly and noninvasively assess blood flow dynamics of the canine prostate. Modifications in gland vascularization can affect seminal plasma production and consequently sperm quality. The aim of this study was to determine the normal blood flow parameters of the prostate artery in beagle dogs and to analyze the correlations between vascular flow and semen quality characteristics. PwD was performed on five beagle dogs (5–6 years) measuring vascular features in four different locations of the prostatic artery (cranial, subcapsular, parenchymal and caudal); the measured features were peak systolic velocity (PSV), end-diastolic velocity (EDV), resistive index (RI) and pulsatility index (PI). Ejaculates were obtained using digital manipulation and semen quality was evaluated by determining macroscopic (total volume, sperm-rich fraction volume, color and pH) and microscopic (sperm motility, morphology, viability and acrosome integrity) characteristics. The values of PSV, PI and RI in cranial and caudal prostatic arteries were significantly higher than in subcapsular and parenchymal arteries (p < 0.05). Moreover. a positive correlation of PSV value in the cranial region of the prostatic artery with total ejaculate volume (p < 0.01, r = 0.612) and sperm concentration (p < 0.01, r = 0.587) was determined. PI index was negatively correlated with sperm concentration (p < 0.01, r = -0.709). In conclusion. the results suggest that the prostatic artery blood flow parameters can affect macroscopic semen quality characteristics in healthy dogs. info:eu-repo/grantAgreement/ES/DGA-FEDER/A17-17R-RAySA info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.752 2020 VETERINARY SCIENCES 19 / 146 = 0.13 2020 Q1 T1 AGRICULTURE, DAIRY & ANIMAL SCIENCE 13 / 63 = 0.206 2020 Q1 T1 0.583 2020 Veterinary (miscellaneous) 2020 Q1 Animal Science and Zoology 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Servián, M.
