What is the success rate of Frozen Blastocyst Transfer?

Couples often find it confusing whether to use fresh embryos or should freeze them for future attempts as both options have their pros and cons. Surprisingly, the latest research reveals that Frozen Embryo Transfer (FET) or Frozen Blastocyst Transfer may have a better success rate than using Fresh Embryo transfer during In Vitro Fertilization (IVF).

In the IVF cycle, the mature eggs are retrieved from the woman's ovaries, fertilized with sperm, and an embryo is created in a laboratory.

Embryo transfer is a phase in an In Vitro Procedure (IVF) where the prepared embryo is divided and multiplies in different cells over the next few days (5 to 6 days) to form a blastocyst in order to be transferred into the uterus or to freeze it for the future attempts. It is seen that on average, only 30 to 50 percent of embryos make it to the blastocyst stage.

Frozen Blastocyst Transfer Process

The main difference between Fresh Embryo and Frozen Embryo is that a fresh embryo transfer will occur 3 to 5 days after the egg retrieval by transferring the fertilized embryo back into the uterus. Whereas, Frozen Embryo Transfer (FET) occurs after a period of time depending on factors and the personal decision of the couple. For frozen Blastocyst Transfer, it is important to prepare your uterus for blastocyst implantation.

There can be multiple reasons why one may choose Frozen Embryo Transfer -

• If you're not ready to be a parent
• Want to delay IVF to a later date
• You have extra embryos
• You're Using Genetic Screening
• You're at a High Risk of (Ovarian hyperstimulation syndrome ) OHSS

The decision for frozen blastocyst implantation is based on your decision and goal. Choosing the right option is significant for both mother and child. You must prepare yourself for every situation and have a healthy discussion while going for IVF treatment in Lucknow.

Here are the benefits of Frozen Blastocyst Transfer.

• Reduces the pregnancy risks of fresh embryo transfer 
• If the first IVF attempt is unsuccessful, the frozen embryos can be thawed and used for transfer in subsequent cycles
• Allows for genetic screening
• Plan for pregnancy when you're ready
• Less expensive in case of multiple transfers rather than repeated fresh IVF cycles
• Reduces the risk of ovarian hyperstimulation syndrome (OHSS) during IVF
• Donate your extra embryos to couples facing infertility
• Allow uterus to return to the normal environment after IVF medications

Does Frozen Embryo Transfer Yield Better Results?

The decision for FET is personal, but it is true that in some cases fresh embryos may be more suitable as per your medical conditions and needs. Many fertility clinics have found that Frozen Embryo Transfers (IVF-FET) are 10% more likely to result in a live birth than a fresh one. Despite this, there are multiple factors that need to be considered as well, such as -

• Mother's age at the time of egg retrieval
• Infertility issues (Endometriosis, PCOS, fibroids, and uterine polyps)
• Medical condition
• The overall health of the child-bearer
• Ovarian reserve and quality of gametes

Choosing either fresh embryo transfer or frozen embryo transfer can be good for you depending on your need, goal, and other factors. For some, using a fresh embryo can be the best and the only option. Whereas for others freezing the blastocyst serves different benefits and sometimes better results.
