As mentioned earlier, sequential embryo transfer is the method of transferring embryos twice, on day 2 / 3 and day 5 / 6. We do this in order to ensure that the embryos that have good grading are not denied the chances of being implanted in natural conditions. Normally two embryos are transferred on day 2 while the remaining 2 or 3 are maintained in sequential media to observe their potential to become blastocysts. Following this a single blastocyst or a maximum of two are transferred. However the chances of multiple births are greatly increased by this method. Kindly see our statistics to know the multiple pregnancy rates. As with all procedures in assisted reproduction these treatments are individualized and are not universally applied.
