[Ectopic pregnancy risk factors after assisted reproductive technology].
Ectopic pregnancies are more frequent among pregnancies resulting from assisted reproductive technology (ART) than in natural conceptions (6% to 7% vs 1%). Fivnat registry has allowed us to analyse 349 ectopics among 6049 clinical pregnancies collected from 1986 to 1990. Ectopic rate decreased with increasing women's age, and since 1986. The risk was also decreased in infertilities of non tubal origin, except for those of unknown origin in which it was at the same level than for tubal infertility. The risk was increased by 65% in stimulation regimens involving clomiphene citrate (CC). The observed decrease from 1986 to 1990 was strongly related to the decrease in use of CC.
