At Repromed our scientists will freeze any good quality embryos following your fresh embryo transfer. These embryos will remain in storage until you would like them thawed and transferred, a procedure known as a frozen embryo transfer (FET). Due to higher survival rates Repromed freezes all embryos at the blastocyst stage (day 5 and/or 6) using a fast freeze technique termed vitrification.
Vitrification is an ultra rapid freeze method that bypasses ice crystal formation. Vitrification is reported to be a superior method of freezing than conventional slow freezing where survival rates range from 70-80% giving rise to increased rates in pregnancy outcome.
Advantages to FET:
Transferring frozen embryos between clinics is a very simple process. If you have embryos stored at a different clinic but would like treatment at Repromed please get in touch with us.
