Purpose: Fertilization and pregnancy rates in patients with obstructive and nonobstructive azoospermia whom underwent ICSI were assessed.  
Method: From Sep. 2001 to Jun.2003, 50 ICSI procedures with precutaneouse epididymal sperm aspiration (PESA) or testicular sperm extraction (TESE) were carried out in obstructive azoospermia and nonobstructive azoospermia patients.  
Results: 172 and 116 MII oocytes were injected in obstructive azoospermia and nonobstructive azoospermia which 69.2% and 64.6% were fertilized respectively. The clinical pregnancy rates were 23.3 and 25% and ongoing pregnancy were similar in the both groups. (20%)  
Conclusion: The azoospemric patients are potentially fertile and using new technique of sperm retrieval in combination with ICSI, they can achieve fertilization and pregnancy. Moreover, the etiology (obstructive versus nonobstructive) didn’t influence the outcome of treatment significantly in the present study.
