The aim of this study was to correlate the Doppler velocimetry of the testicular artery with kinetics of the epididymal spermatozoa in dogs. Twenty\u2010two dogs (44 testicles) were evaluated by Doppler ultrasonography in five regions of the testicular artery before orchiectomy. Spermatozoa were recovered by the epididymal tail compression technique and analysed for kinetics on a computer\u2010assisted semen analysis (CASA system). Morphology (modified Karras) and sperm membrane integrity were analysed by eosin\u2013nigrosine staining. Data were analysed by Pearson's correlation test (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.01). The mean total motility was 69.0%\u00a0\u00b1\u00a017.7, progressive motility was 43.7%\u00a0\u00b1\u00a014.7, average path velocity (VAP) was 127.0\u00a0\u00b5m\/s\u00a0\u00b1\u00a020.7, curvilinear velocity (VCL) was 221.0\u00a0\u00b5m\/s\u00a0\u00b1\u00a031.1, and sperm velocity index (SVI) was 389.9\u00a0\u00b1\u00a056.1. There were positive correlations between the peak systolic velocity (PSV) in the proximal supratesticular region with the SVI (<jats:italic>r<\/jats:italic>\u00a0=\u00a0.529), VCL (<jats:italic>r<\/jats:italic>\u00a0=\u00a0.555) and VAP (<jats:italic>r<\/jats:italic>\u00a0=\u00a0.473), and a negative correlation with the percentage of slow spermatozoa (<jats:italic>r<\/jats:italic>\u00a0=\u00a0\u2212.463). The results suggest that the testicular artery blood flow velocity can positively affect the speed of spermatozoa movement. For the first time, we have correlated sperm kinetics with the Doppler evaluation of the testicular artery in dogs.<\/jats:p>","DOI":"10.1111\/rda.13672","type":"journal-article","created":{"date-parts":[[2020,3,9]],"date-time":"2020-03-09T16:15:27Z","timestamp":1583770527000},"page":"720-725","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Correlation of testicular artery Doppler velocimetry with kinetics and morphologic characteristics of epididymal sperm in dogs"],"prefix":"10.1111","volume":"55","author":[{"given":"Luiz Guilherme Corsi","family":"Trautwein","sequence":"first","affiliation":[{"name":"Departamento de Cl\u00ednicas Veterin\u00e1rias Universidade Estadual de Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne Kemmer","family":"Souza","sequence":"additional","affiliation":[{"name":"Departamento de Cl\u00ednicas Veterin\u00e1rias Universidade Estadual de Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guilherme Schiess","family":"Cardoso","sequence":"additional","affiliation":[{"name":"Departamento de Cl\u00ednicas Veterin\u00e1rias Universidade Estadual de Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karina Keller Marques","family":"da Costa Flaiban","sequence":"additional","affiliation":[{"name":"Departamento de Medicina Veterin\u00e1ria Preventiva Universidade Estadual de Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio Cezar","family":"de Oliveira Dearo","sequence":"additional","affiliation":[{"name":"Departamento de Cl\u00ednicas Veterin\u00e1rias Universidade Estadual de Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8416-2450","authenticated-orcid":false,"given":"Maria Isabel Mello","family":"Martins","sequence":"additional","affiliation":[{"name":"Departamento de Cl\u00ednicas Veterin\u00e1rias Universidade Estadual de Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,3,28]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.7860\/jcdr\/2017\/23927.9886"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod64.1.13"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939\u20101676.2007.tb03005.x"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439\u20100531.2011.01937.x"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/rda.12557"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12917\u2010015\u20100363\u20103"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rvsc.2014.03.008"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2015.05.015"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748\u20105827.1991.tb00936.x"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/rda.12825"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.151.5.140"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1439\u20100531.2001.00288.x"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.7863\/ultra.32.8.1427"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0015-0282(16)58044-3"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.12891\/ceog18102014"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439\u20100531.2009.01431.x"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.anireprosci.2015.07.012"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0272.1990.tb02013.x"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365\u20102605.1988.tb01023.x"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439\u20100531.2006.00685.x"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0175878"},{"key":"e_1_2_10_23_1","first-page":"115","article-title":"Colora\u00e7\u00e3o esperm\u00e1tica segundo Karras modificado pelo emprego de Barbatim\u00e3o (Stryphnodendrum barbatiman)","volume":"40","author":"Papa F.
