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.
What is 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.
Frozen embryo transfer (FET)
Advantages to FET:
- If you ovulate naturally no drugs are required on a frozen embryo transfer cycle resulting in a simpler, more natural cycle of treatment.
- It is less costly than another fresh IVF cycle.
Transferring embryos between clinics
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.
