An IVF cycle may result in successful pregnancy in 46 % of women under the age of thirty, but others will need to repeat the procedure.
In these cases Frozen Embryo Transfer saves time, expenses and the additional physical stress of having to undergo the elaborate process of ovulation induction and egg collection all over again. The embryos from one cycle if unused, can be frozen, and used for the next cycle of IVF.
Not all embryos that are produced during an IVF cycle are used up in the cycle. Doctors prefer using a single embryo to prevent multiple pregnancies and the rest are frozen and stored in case of future need. They can also be used as donor embryos, if personal need does not arise.
IVF Frozen embryo transfer is a technique by which a frozen embryo from the last IVF cycle can be softened and placed in the woman's uterus in the next cycle. This process of freezing and thawing embryos to produce babies is the one of the greatest boon in assisted reproductive technology.
