A frozen embryo transfer (FET) is a common procedure in IVF, where an embryo that has been previously frozen is thawed and transferred into the uterus.
During IVF cycle, if there are surplus embryos, we freeze those additional embryos for future use. On occasions, all embryos are electively frozen (freeze all) due to medical reasons. If patients are at risk of developing ovarian hyperstimulation syndrome, electively freezing embryos during IVF cycle is a common practice.
Advances in freezing techniques, especially vitrification, have made FET a highly effective and widely used option.
FET may be part of your treatment plan for several reasons:
• To use embryos from a previous IVF cycle
• As part of a freeze-all approach for medical or safety reasons
• To allow your body time to recover from stimulation medications before transfer
Your specialist will guide you on the best timing and approach based on your individual circumstances.
Frozen embryo transfer offers a number of advantages:
• Allows the uterine environment to return to a more natural state before transfer
• Can reduce certain pregnancy-related risks compared to fresh transfers
• Eliminates the risk of ovarian hyperstimulation syndrome (OHSS) during the transfer cycle
• Enables embryos to be stored and used in future cycles, reducing the need for repeat egg collection
FET is considered safe and well-established, but there are a few things to be aware of:
• A small number of embryos may not survive the thawing process
• As with any embryo transfer, pregnancy is not guaranteed
Your care team will discuss your individual chances of success and guide you through your options.
A frozen embryo transfer can be performed in two ways:
• Natural cycle - tracking your natural ovulation
• Medicated cycle - using hormones to prepare the lining of the uterus
Your specialist will recommend the approach that best suits your cycle and treatment plan.
