Should We Transfer Two Embryos?

With donor embryos that are tested (normal chromosomes by PGS) transferring two embryos at once results in a 70-75 % pregnancy rate with a very high twins rate. Taking those same two embryos, transferred one at a time, results in an approximately 93% cumulative pregnancy rate with a much lower rate of complications.

Does transferring two embryos increase chance of pregnancy?

Though it may seem logical that transferring two embryos would double your odds of getting pregnant, this isn't actually the case! Transferring multiple embryos at once only modestly increases the odds of pregnancy, not doubles it.

Is 2 embryos good for IVF?

Transfer of two embryos does not diminish the chance of a birth when compared with three embryo transfer, if more than four embryos are available for transfer (Templeton and Morris, 1998). However, in many countries more than two embryos are still generally transferred.
