[Ectopic pregnancy after the treatment of infertility by the method of extracorporeal fertilization].

During October 1987 to June 1989, 609 infertile couples have been treated using in vitro fertilization and embryo transfer (IVF-ET). Of 78 conceptions (15.7% of transferred embryos), 6 (7.7%) pregnancies were ectopic (5 tubal and 1 ovarian). After diagnosis of ectopic pregnancy all the patients were operated; the ovary was resected in 1 patients and tubectomies were done in 5 patients (laparoscopically in 1). All the diagnoses were confirmed histologically. Since prevention of ectopic pregnancy in IVF-ET is not reliable, the patients enrolled for IVF-ET should be considered to be at risk and closely followed up.
