Objective To study the effectiveness of percutaneous testicular sperm aspiration(PTSA) plus intracytoplasmic sperm injection (ISCI) in treating male infertilitycaused by azoospermia.ized in our hospital from September 1998 to December 2000 were enrolled into thisstudy. Among the 135 patients, 71 were with obstructive azoospermia, 23 were withcongenital azoospermia, and the other 41 with idiopathic azoospermia. All thesepatients underwent ICSI with testicular sperm by PTSA. The fertilization rate wasdetermined.Results The mean concentration of testicular sperm was 73. 5± 42. 59/μL and theaverage motility was 1. 5± 1. 17% (ranging from 1 % to 5% ). The motion grade ofthe sperm was 1. A total of 1 263 eggs were obtained and ICSI was performed. AfterICSI, 849 eggs were fertilized with a total fertilization rate of 67.2%. In 71 patientswith obstructive azoospermia, 79 cycles of ICSI were performed and the spouses of 32patients achieved pregnancy, with a pregnancy rate of 40. 5%. In 23 patients withcongenital azoospermia, 28 cycles of ICSI were performed and the spouses of 9 pa-tients got pregnancy, having a pregnancy rate of 32. 1%. In the group of 41 patientswith idiopathic azoospermia, 41 cases were given ICSI and the spouses of 8 patientsgot pregnancy, with a pregnancy rate of 19. 5%.Conclusion ICSI in combination with PTSA is an effective method of treatingazoospermia induced male infertility, especially obstructive azoospermia.
