Comparison of day 2 tubal embryo transfer with day 3 embryo transfer into the uterus of intracytoplasmic sperm injection derived human embryos (original) (raw)

2006, Taiwanese journal of obstetrics & gynecology

To compare the results of embryo transfer into the uterus (ET) performed on day 3 vs. tubal embryo transfer (TET) on day 2 in couples diagnosed with male factor infertility. We collected data from 34 and 110 patients who underwent intracytoplasmic sperm injection (ICSI) followed by either TET on day 2 or ET on day 3 (January 2001-June 2005), respectively. All couples were diagnosed with male factor infertility; there were no tubal or uterine factors, diminished ovarian reserve, pelvic adhesions, history of polycystic ovary syndrome or previous ovarian surgery. The clinical pregnancy rates of day 2 TET and day 3 ET following ICSI were 64.71% and 57.27% (p > 0.05), respectively. The corresponding implantation rates were 35.47% and 29.58% (p > 0.05), respectively. The implantation and clinical pregnancy rates of ET on the 3rd day following ICSI were similar to the rates obtained with TET 2 days after ICSI. Therefore, ET performed 3 days after ICSI should be the first choice for c...
