AB  - This study investigated the epididymis of mature boars (n=10) by means of B-mode 
      ultrasound and grey-scale analysis (GSA) for echogenicity (EG) determination 
      using an ultrasound unit HS 1500V, a linear transducer (frequencies 7.5-9.0 MHz), 
      and standardized unit settings. All boars had their epididymal caput, corpus and 
      cauda scanned six times before and after semen collection, respectively, at 
      weekly intervals. Semen was subjected to spermatological examination including 
      volume, total and forward motility, sperm abnormalities, as well as total sperm 
      count and concentration. The caput and corpus both had a homogeneous fine 
      echotexture. The cauda was homogeneous too but had a marbled echotexture. 
      Echogenicity before and after semen collection was caput > corpus > cauda, 
      respectively (p<0.001). Echogenicity was higher before than after semen 
      collection for all parts of the epididymis, respectively (p<0.001). Echogenicity 
      of the caput correlated slightly positively with the total sperm count 
      pre-collection (r=0.301; p=0.020) and with ejaculate volume pre- and 
      post-collection (r=0.302 vs 0.306; p=0.017 vs 0.019), and slightly negatively 
      with sperm concentration post-collection (r= -0.275; p=0.034). No relationship 
      was found for EG of the corpus and cauda for any of the ejaculate parameters. In 
      conclusion, B-mode ultrasound and GSA proved feasible for imaging the epididymis 
      in boars. Single relationships between EG and ejaculate parameters were found and 
      deserve further investigation.
