A randomized prospective study was performed to compare the effects of a midfundal versus a deep fundal transfer technique on subsequent intrauterine and ectopic PRs after IVF. The clinical intra-uterine PR after the deep fundal transfer was 12.4% per cycle with a 1.5% ectopic PR (which represented 12.2% of the pregnancies) versus 14.2% IUPs per cycle with a 0.4% ectopic rate (representing 3% of pregnancies) after midfundal transfers. The midfundal technique appears superior to deep fundal procedures because of a lower percentage of EPs without any sacrifice of the intrauterine PR after midfundal transfers.
进行了一项随机前瞻性研究，以比较宫底中部与宫底深部移植技术对体外受精后随后的宫内和异位妊娠率的影响。宫底深部移植后的临床宫内妊娠率为每个周期12.4%，异位妊娠率为1.5%（占妊娠的12.2%），而宫底中部移植后每个周期的宫内妊娠率为14.2%，异位妊娠率为0.4%（占妊娠的3%）。宫底中部技术似乎优于宫底深部操作，因为宫底中部移植后异位妊娠率较低，且不牺牲宫内妊娠率。
