反复附睾或睾丸取精的无精子症病人妊娠结局

目的 :分析反复附睾或睾丸取精进行卵胞质内单精子注射治疗的妊娠结局。　方法 :收集 2 0 0 1年 1月～2 0 0 2年 12月进行 2周期以上附睾或睾丸取精进行卵胞质内单精子注射治疗的无精子症病人 31例 (共 4 3个周期 ) ,对取精情况及受精、种植和妊娠结局进行总结。　结果 :2 4例病人顺利从附睾取精 ,7例病人从睾丸取精 ,无 1例出现感染、血肿或局部的功能障碍。与第 1周期附睾或睾丸取精 15 4例 (共 15 4个周期 )的受精率、种植率和临床妊娠率比较 ,结果分别是 78.39%与 73.6 4 % ,19.6 8%与 18.38%和 34.88%与 37.91% ,差异无显著性 (P >0 .0 5 )。　结论 :无精子症病人进行反复附睾或睾丸取精 ,是安全和可耐受的 ,其妊娠结局与第 1周期比较无统计学差异。

Outcome of Repeated Epididymal Sperm Aspiration or Testicular Sperm Extraction in Azoospermic Patients

Objective: To review the outcome of repeated percutaneous sperm aspiration (PESA) and testicular sperm extraction (TESE) for intracytoplasmic sperm injection (ICSI). Methods: Forty three cycles of 31 cases of azoospermic patients which underwent at least two PESA or TESE for ICSI from January 2001 to December 2002 were collected. The sperm retrieval, fertilization, implantation and clinical pregnancy were analyzed. Results: Twenty four cases underwent PESA and 7 cases underwent TESE. There were not any complications in these patients. Compared with the first cycle of 154 cases, the fertilization rate, implantation rate and clinical pregnancy rate were 78.39 % vs 73.64 %, 19.68 % vs 18.38 % and 34.88 % vs 37.91 %, respectively( P > 0.05 ). Conclusions: Repeated PESA or TESE is safe and well tolerated in azoospermic patients. Compared with the first cycle, the differences of repeated PESA or TESE cycles in fertilization rate, implantation rate and clinical pregnancy rate were not statistically significant.
