The efficiency of two methods of ultrasound-guided aspiration of pre-ovulatory oocytes was compared in 238 treatment cycles, of which 166 were by the transabdominal-transvesical (TA) route and 72 by the transvaginal (TV) route. Successful collection of at least one oocyte was achieved in 86% of TA attempts and in 97% of TV attempts. Significantly less oocytes were collected from follicles by the TA methods than by the TV methods: 374 oocytes were obtained from 797 follicles (46% recovery) and 242 oocytes from 338 follicles (72% recovery), respectively. Although fertilisation occurred more frequently in TA-recovered oocyte (70% versus 54%), the incidence of cleavage per inseminated oocytes collected by these TA and TV methods was similar (49% versus 44%, respectively). Results of this study therefore suggest that the TV method is superior to the TA approach for oocyte recovery.
在238个治疗周期中比较了两种超声引导下排卵前卵母细胞抽吸方法的效率，其中166个采用经腹-经膀胱（TA）途径，72个采用经阴道（TV）途径。TA途径尝试中86%成功采集到至少一个卵母细胞，TV途径尝试中97%成功采集到至少一个卵母细胞。TA方法从卵泡中采集到的卵母细胞明显少于TV方法：分别从797个卵泡中获得374个卵母细胞（回收率46%）和从338个卵泡中获得242个卵母细胞（回收率72%）。尽管TA采集的卵母细胞受精更频繁（70%对54%），但通过这些TA和TV方法采集的每个受精卵母细胞的分裂发生率相似（分别为49%对44%）。因此，本研究结果表明，在卵母细胞采集方面，TV方法优于TA方法。
