Embryo transfer window and luteo-placental shift in donor egg program

Research output: Chapter in Book/Report/Conference proceedingChapter


Premature ovarian failure(POF) affects 1-3% of the general population. Once regarded as hopelessly sterile, these women can become pregnant through an oocyte donation program by use of assisted reproductive technologies like in vitro fertilization and embryo transfer ( IVF/ET), gamete intrafallopain transfer (GIFT), or transtubal embryo transfer (TET). Eleven non-surgical transfers of donor ooctes producting successful pregnancies had been reported. However, issues like receptivity endometrium, window of transfer, and timing of luteo-placental shift remained controversial.
