Cryopreservation of embryos
If the treatment results in more high quality embryos than those transferred, ‘surplus’ embryos can be cryo-preserved and stored in liquid nitrogen at -196°C. The embryos can later be thawed and transferred usually without the need for any hormone stimulation.
Even though we only freeze embryos of very good quality, not all embryos will survive the freezing and subsequent thawing.
