Occasionally a woman having IVF treatment will be advised to freeze all her embryos and not to transfer any immediately if the lining of the uterus has not developed to a suitable stage or if she is at risk of developing ovarian hyper-stimulation syndrome (OHSS). As only one (or two) will be transferred to the uterus immediately, the rest can be frozen to use in another IVF cycle if the first transfer does not result in a pregnancy, or at a later time to create a sibling.
When ovaries are stimulated in a typical IVF or ICSI cycle, they produce multiple eggs for insemination and this often leads to a number of healthy embryos being created. When is a frozen embryo cycle recommended? The process is a routine procedure at Life Fertility Clinic. What is a frozen embryo transfer cycle?Ī frozen embryo transfer (FET) cycle means thawing one or more embryos (frozen during a previous treatment cycle) and transferring that embryo (or embryos) to the uterus in order to try to establish a pregnancy. This fact sheet explains what is involved in the frozen embryo transfer process.
If you are undergoing IVF and have had one or more embryos frozen, you may wish to use them in a future cycle.
