This study was carried out to compare the reproductive capability of testicular sperm injection (ICSI) technique. From November 2006 to December 2007, 198 intracytoplasmic sperm injection cycles were studied. One hundred thirty of 198 cycles were carried out using epididymal sperm and 68 were carried out using testicular sperm. The results showed that no significant differences were observed in the rates of fertilization and embryo transfer between obstructive and nonobstructive etiology and between epididymal and testicular spermatozoa. The abortion rate of motile epididymal or testicular spermatozoa was lower than that of immotile spermatozoa.
