| Abstract: |
The present study was divided into two parts:Part I: (Gross anatomical studies)The mean testicular weight, testicular and epididymal dimensions wereestimated using the specimens, which were obtained from slaughterhouses,immediately after slaughtering.The testicular weight ranged from (226-250 gm.), its width of about (4.6-5cm) and the length of the testis measured (7.1-8 cm). The epididymis formed a caplike structure on the head extremity of the testis, it descended about 4.5 cm on thecranial border of the testis, the epididymal tail was large bulbous structure of about2.6 cm width and extended beyond the tail extremity of the testis about 2.2 cm.Blood supply and venous drainage of the testis and epididymis wereconducted on 11 specimens obtained immediately after slaughtering, flushed withwarm saline (37 CO) and injected with colored latex compound (red latex and bluelatex) into the cannulated testicular artery and vein respectively. A Life animal waskilled, flushed with warm normal . saline and ’injected with colored latex todemonstrate the origin of the testicular artery and vein.The present study revealed that the testicular artery originated from theventrolateral aspect of the abdominal aorta and divided into, abdominal part, whichgive the epididymal artery, funicular part, which was highly convoluted, and themarginal part, which passed on the epididymal border of the testis. It was dividednear the tail extremity of the testis into medial and lateral primary branches, eachone, gave rise about 10-15 secondary branches. These branches passed deeply intothe testicular parenchyma toward the mediastinum testis as centripetal branches,which formed the mediastinal plexus and give the centrifugal branches.t IThe marginal part of the testicular vein drained the extensivesubalbugineal venous plexus and the major subalbugineal veins.
