title: Embryo transfer technique as a cause of ectopic pregnancy in in vitro fertilization.
abstract: 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.
