Eggs, embryos and blastocysts
May 26, 2010 @ 04:06 PM — by Scott Hutchinson
In our practice, if you are 35 or under or are using donor eggs, transferring two embryos does NOT increase your chance of pregnancy, it just INCREASES the chance of TWINS. We are even finding that in our patients under 40 this may be the case, as well. We will only transfer and/or cryopreserve blastocysts that have a regular outer cell mass, a fluid filled cavity and an inner cell mass. These are the embryos that have the potential to make a pregnancy. These blastocysts freeze and thaw well, as evidenced by our rate of pregnancy in frozen embryo transfers (the same as fresh).
