Testicular sperm can be obtained from patients with non-obstructive azoospermia. However, there is not enough evidence concerning whether fresh or frozen-thawed sperm is better for successful pregnancy. We retrospectively compared initial treatment results of intracytoplasmic sperm injection using fresh and frozen-thawed testicular sperm in our institution. From August 1997 to May 2006, a total of 27 cases including 18 cases using fresh sperm (269 oocytes) and 9 cases using frozen sperm (97 oocytes) were evaluated. In the fresh and frozen sperm groups 33.4 and 32.9%, respectively, developed good quality embryo. There was no significant difference between the two groups in successful pregnancy and birth rates.
非梗阻性无精子症患者可获取睾丸精子。然而，关于新鲜精子或冻融精子对成功妊娠更有利，目前尚无足够证据。我们回顾性比较了本院使用新鲜和冻融睾丸精子进行卵胞浆内单精子注射的初始治疗结果。1997年8月至2006年5月，共评估了27例患者，其中18例使用新鲜精子（269个卵母细胞），9例使用冷冻精子（97个卵母细胞）。新鲜精子组和冷冻精子组分别有33.4%和32.9%发育出优质胚胎。两组在成功妊娠率和出生率方面无显著差异。
