The present study was conducted on sixteen buffalo fetuses ranging from 2 cm to 25 cm curved crown rump lengthÂ (CVRL) collected from abattoir. The Wolffian ducts are the most important structures, precursor of the epididymal ducts and theÂ vasa differentia in males. The Wolffian duct was observed at the entrolateral aspect of cranial part of mesonephros at 2 cmÂ CVRL (37 days). At 3 cm CVRL (42 days), both the MÃ¼llerian duct and Wolffian ducts were present. The development ofÂ Wolffian ducts and degeneration of MÃ¼llerian duct was noticed at 5.2 cm CVRL (52 days). The mesonephric duct was lined byÂ simple cuboidal epithelium upto 11 cm CVRL (69 days) but changed to simple columnar epithelium from 12.5 cm CVRL (85Â days) onwards. The epithelial cells were resting on a well distinct basement membrane. The duct was straight upto 13.7 cmÂ CVRL (90 days) then bent and curved over the cranial pole of testis at 19 cm CVRL (114 days) and started to differentiate intoÂ ductus epididymidis.
