Frozen Embryo Transfer

The Frozen Embryo Transfer, commonly referred to as FET procedure involves thawing and then transferring the embryo into a woman’s uterus for further pregnancy. Embryos are transferred to the uterus through a catheter. This frozen embryo transfer procedure does not involve any anesthesia and is rather painless. The FET gaining popularity due to its high successful pregnancy rates and safety. A frozen embryo from a previous IVF cycle is used in this process. A woman undergoes the standard IVF procedure during this procedure. The embryos are frozen for use in a future cycle instead of transferring the embryos back into the uterus in the same cycle. A woman can freeze her own eggs or choose to use donor eggs for her pregnancies. To reduce the effect of desynchronization, the eggs are transferred in a later cycle to help the woman recover from her current IVF cycle. To identify the optimal time in the patient preparing for an FET cycle to transfer the embryo, the doctor recommend various blood test and ultrasound reports.

The FET Process

Medicated FET

In medicated FET also commonly known as a programmed FET, the doctor suggests a course of hormone medication to the patient to ensure that the patient’s lining of the uterus (endometrium) is ready to receive the thawed embryos.

Natural FET 

Natural FETs involve minimal or no medication. The doctor closely monitor the patient’s menstrual cycle by ultrasound and blood tests in order to identify the optimal day for embryo transfer.

Transfer and Post-Transfer

The embryo transfer is scheduled when the doctor identify that the FET patient’s endometrium is approaching its peak receptivity.

Pregnancy Success Rates with FET

Due to some advanced freezing techniques , like advanced flash-freezing vitrification technologies, Frozen Embryo Transfer generally does not have a negative impact on their success rate and result in increased pregnancy and live birth rates, decreased miscarriages, and result in healthier babies. Generally, pregnancy probability is higher for frozen embryos than embryos transferred during a fresh IVF cycle. Various factors that might affect the success rate of a frozen embryo transfer include uterine factors such as fibroids or a uterine septum, as well as the quality and genetic content of the embryos, immunologic, environmental, and infectious factors. Dr Shivani Sachdev Gour will evaluate for all these factors before performing the frozen embryo transfer at SCI Healthcare and SCI IVF Hospital and Multispecialty Center. Old slow freezing technology generates few vital embryos, but the advanced vitrification method used at SCI Healthcare and SCI IVF Hospital substantially reduces loss rates.

Benefits of Frozen Embryo Transfer

Embryo freezing may be a better option for certain patients as compared to IVF and fresh embryo transfer, such as:

  1. It offer a higher pregnancies success rate
  2. It provides a more natural uterine environment for successful pregnancy
  3. It is best suitable for women with genetic disorders that affect reproduction
  4. It will be helpful for the people who will soon undergo chemotherapy
  5. It helps same-gender couples who wish to have children
  6. It is less stressful
