The purpose of this study was to analyse the risk factors, stimulation characteristics, site and outcome of pregnancy and future fecundity of patients who develop ectopic pregnancies after in-vitro fertilization (IVF). Of 3145 transfer cycles between January 1981 and July 1989, 27 (3.3%) of the resulting 825 pregnancies were ectopic. There was a significantly greater incidence of a prior ectoptc pregnancy in the study group compared to the controls. Compared to matched controls with intrauterine pregnancies, the study group had significantly higher peak oestradlol levels. Twentyone ectopic pregnancies were ampullary, two were interstitial, one-was abdominal, one was cervical and two were hetero topic. Sixteen of the patients subsequently underwent 40 IVF attempts with a pregnancy rate of 28% per transfer. We conclude that patients with a prior ectopic pregnancy are at risk for an IVF ectopic pregnancy. The subsequent IVF outcome of those who develop ectopic pregnancies after IVF is encouraging.
