Delayed embryo implantation following in vitro fertilization and embryo transfer (IVFET)

J Assist Reprod Genet. 1996 Aug;13(7):536-9. doi: 10.1007/BF02066604.

Abstract

Purpose: Our goal was to compare serum human chorionic gonadotropin (hCG) levels in singleton pregnancies achieved following IVFET with those achieved following spontaneous conception.

Results: The mean serum hCG level of patients who became pregnant following IVFET lagged 1.5 days behind that of patients who became pregnant spontaneously.

Conclusions: The use of gonadotropin releasing hormone analogue as part of the stimulation protocol leading to egg retrieval and IVFET results in a delay in embryo implantation.
