Oocyte collection for in vitro fertilization was performed in 105 cycles (65 patients) by ultrasonically guided percutaneous puncture (63 cycles) or laparoscopy (42 cycles). During the ultrasonically guided approach an open or closed needle system was used. During both ultrasonically guided and laparoscopic follicle aspiration, all visible follicles were punctured. The mean number of punctured follicles per cycle was comparable for both techniques. Despite a significantly higher mean number of oocytes per cycle harvested during laparoscopy, the mean number of embryos per cycle was not essentially different with the two techniques. Also no difference could be established between the ultrasonically guided open and closed needle systems.
通过超声引导下经皮穿刺（63个周期）或腹腔镜检查（42个周期）对105个周期（65例患者）进行体外受精的卵母细胞采集。在超声引导方法中，使用了开放式或封闭式针系统。在超声引导和腹腔镜卵泡抽吸过程中，所有可见卵泡均被穿刺。两种技术每个周期穿刺卵泡的平均数量相当。尽管腹腔镜检查每个周期收获的卵母细胞平均数量明显更高，但两种技术每个周期的胚胎平均数量没有本质差异。超声引导的开放式和封闭式针系统之间也没有差异。
