Efforts to transfer ectopic embryos to the uterine cavity: A systematic review

Abstract

Aim: The objectives of this review are to identify and characterize attempts to transfer ectopic embryos to the uterus, and to understand arguments for and against the feasibility of such an intervention.

Methods: An electronic literature search involved all English language articles published in MEDLINE (1948-), Web of Science (1899-), and Scopus (1960-) before July 1, 2022. Articles were included that identify or describe attempts to transfer the embryo from its ectopic location to the uterine cavity, or discuss the feasibility of such an intervention; there were no exclusion criteria (PROSPERO registration number CRD42022364913).

Results: The initial search yielded 3060 articles; 8 articles were included. Of these, two articles were case reports that described the successful transfer of the embryo from its ectopic location to the uterus, followed by term births; both cases involved laparotomy with salpingostomy, followed by transfer of the embryonic sac into the uterine cavity through an opening made in the uterine wall. The other six articles varied in type, and provided a number of arguments for and against the feasibility of such a procedure.

Conclusions: The evidence and arguments identified in this review may help manage expectations for those interested in transferring an ectopically implanted embryo in the hope of continuing the pregnancy, but who are uncertain about the extent to which such a procedure has been attempted or may be possible. Isolated case reports, with no evidence of replication, should be interpreted with the utmost caution and do not constitute a procedure for clinical use.

Keywords: ectopic pregnancy; embryo transfer; minimally invasive surgical procedures; tubal pregnancy; women's health.
