Has an ectopic pregnancy's blastocyst ever been successfully extracted from the Fallopian tube and made to implant in the uterus?
Not in an independently confirmed case.
A paper was once published claiming this was performed successfully:
- Pearce JM, Manyonda IT, Chamberlain GV. Term delivery after intrauterine relocation of an ectopic pregancy. Br J Obs Gynaecol. 1994; 101:716–7.
This article and several others by the same author Malcolm Pearce were found to be fraudulent and were retracted:
- Lock S. Lessons from the Pearce affair: handling scientific fraud. BMJ. 1995; 310(6994):1547-8.
Yes, this has been done by
- Wallace, C. J. (1917) Transplantation of ectopic pregnancy from fallopian tube in cavity of uterus. Surg Gynecol Obstet 24, 578-579
- Shettles, L. B. (1990) Tubal embryo successfully transferred in utero. Am J Obstet Gynecol 163, 2026-2027
