ABSTRACT
This study was carried to determine the possibility of finding motile spermatozoa and fertilization, pregnancy rate after testicular sperm extraction(TESE) with ICSI in obstructive and non-obstructive azoospermic patients. In 154 cases(132 patients), obstructive azoospermia was 77 cases and non-obstructive azoospermia was 77 cases. In obstructive azoospermia, patients generally showed normal spermatogenesis and included vas agenesis(n=8), multiple vas obstruction(n=7), epididymal obstruction (n=54). Total of 982 retrieved oocytes were obtained and 84.4% were injected. The fertilization rates with 2 PN and cleavage rate were 72.5% and 62.3%, .respectively. 30 pregnancies(38.9%) were achieved and the ongoing pregnancies were 22 cases (28.6%). In non-obstructive azoospermia, patients showed hypospermatogenesis(n=49), maturation arrest(n=4), Sertoli cell only syndrome (n=24). The various stages of spermatogenic cell could be retrieved by TESE and could be reached normal fertilization and embryo development with ICSI. Total of 1072 retrieved oocytes obtained and 80.2% were injected. The fertilization rates with 2 PN and cleavage rate were 52.8% and 68.9%, respectively. 22 pregnancies(30.1%) were achieved and the ongoing pregnancies were 19 cases(26.0%). Conclusively, the combination of TESE with ICSI using testicular spermatozoa can achieve normal fertilization and pregnancy rate and effective method in obstructive and non-obstructive azoospermic patients.
