Blastocyst Transfer

At CRGH we perform embryo transfers at the blastocyst stage. Blastocysts form on day 5 or 6 of embryo development (6 or 7 days post egg collection) and are characterised by a fluid filled cavity where cells have differentiated into either the trophectoderm or inner cell mass. Transfer at the blastocyst stage mimics the natural environment more closely and allows an enhanced selection of embryos translating into a higher chance of pregnancy than transfer of day-3 embryos.

In 2020, all fresh embryo transfers at CRGH were performed at the blastocyst stage. You can find our latest success rates here.
