We compared the retrieval efficiency of single- (direct follicular aspiration) and double-lumen-needle (attained with follicular flushing) procedures in normal-responder IVF-intracytoplasmic sperm injection cycles. This prospective randomized study did not demonstrate a beneficial effect of double-lumen needle retrieval compared with single-needle retrieval in normal-responder IVF-intracytoplasmic sperm injection cycles in terms of retrieved oocytes, clinical pregnancy rates, and live birth rates.
我们比较了在正常反应的 IVF-胞浆内单精子注射周期中,单针(直接卵泡抽吸)和双针(通过卵泡冲洗获得)程序的检索效率。这项前瞻性随机研究表明,在正常反应的 IVF-胞浆内单精子注射周期中,与单针检索相比,双针检索在获取卵母细胞、临床妊娠率和活产率方面没有有益效果。
