The number of embryos to be transferred will be determined by you, the physician and the embryologist prior to the embryo transfer so as to maximize the possibility of pregnancy and minimize the risk of multiple gestations.  Patient age, infertility factor(s), embryo quality, previous failed cycles, and other factors are taken into account.  Multiple pregnancies can be devastating to the health of both mother and children.  In an effort to curtail the problem, national guidelines published by the Practice Committee of the Society in Assisted  Reproductive  Technologies (SART) of the American Society for Reproductive Medicine (ASRM) recommend limits on the number of embryos to transfer of which we adhere to.
