We present our first experience with human embryo cryopreservation. In our hands the best results were obtained with cryopreservation of pronuclear-staged embryos using propanediol as cryoprotectant. In this group 3 embryos out of 4 continued their development after thawing. The advantages of embryo cryopreservation in IVF programs are discussed.
