title: Low ectopic pregnancy rates after in vitro fertilization: do practice habits matter?
abstract: In a 6-year review of ectopic pregnancies (EPs) after fresh and frozen embryo transfers in IVF cycles conducted at a large university-based program, we report an overall 0.9% rate of EP that seems to have increased with the programmatic shift to routine blastocyst transfer, but remains lower than nationally reported rates. Aggressive management of tubal disease may contribute to low rates of EP, whereas blastocyst transfer may increase the rate.
