This study was conducted to evaluate postpubertal testicular and epididymal epithelial changes induced by unilateral epididymal and vasal obstruction in rats by measuring epithelium thickness of seminiferous tubuli (MSTet) and epithelium thickness of ductus epididymis (MDEet). Rats were randomly divided into 3 groups: group I underwent unilateral epididymal ligation; group II underwent unilateral vasal ligation and group III received sham operations. MDEet on the ipsilateral side of the epididymal ligation group significantly decreased compared to the contralateral side and sham group. For the contralateral side of the ligated vas, MDEet significantly decreased compared to the ipsilateral side and sham group. MSTet was less on the side of the operation than the contra lateral side and the sham group after both surgical procedures. The obstruction point of the male genital tract affect sperm parameters for clinical extraction or aspiration procedures.
