OBJECTIVE: To study the incidence, risk factors and clinical manifestation for ectopic pregnancy (EP) after in vitro fertilization and embryo transfer (IVF-ET). METHODS: A retrospective study of IVF and intracytoplasmic sperm injection (ICSI) pregnancies was performed between March 1998 and December 1999. RESULTS: A total of 432 woman conceived after IVF or ICSI were studied. The rate of EP was 3.9%, corresponding with 17 EPs, of which 4 (82.4%) were heterotopic pregnancy (HP). There were 14 EPs in tubal factor group, and 3(17.6%) in nontubal factor group. There appear to be no relationship between d 2 ET and d 3 ET, ovulation induction and age. The number of embryo transferred is 3.5 in EP and 4.1 in HP. CONCLUSIONS: Tubal pathology is associated with increased risk of EP. Close hormonal and ultrasonographic follow-up in pregnancies achieved in IVF treatments are recommended for early diagnosis and avoidance of further undesired consequences.
