Morphometric parameters of testis-epididymis and epididymal sperm parameters of pubertal Iranian buck (Caprus hircus)

The aim of the present study was to find the morphological parameters of testis-epididymis and their relationship with epididymal sperm parameters of pubertal Iranian domestic buck. Total pairs of 40 testes-epididymes were provided from local slaughterhouse and transported to the laboratory. Thirty pairs were evaluated for anatomical features and remained 10 pairs were evaluated for both anatomical and epididymal sperm parameters. Mean weight of testes-epididymes، testis and epididymes were 114. 5، 1o1. 5 and 12. 8 g respectively. No significant difference was detected between right and left on the analyzed parameters (P>0. 05)، except epididymes weight (P<0. 05). Mean percentages of motility and viability for Iranian domestic goat were 86. 4 and 94. 1، respectively، that significantly reduced after cryopreservation with Bioxell using one step dilution procedure. The results of the present study show biometrical parameters of testes and epididymes of Iranian pubertal buck and revealed no significant correlation between biometrical parameters and epididymal sperm parameters.
