Blastocyst Transfer in Delhi
Blastocyst Transfer. Step for IVF Success
Understanding the Blastocyst Stage in IVF:
During the IVF process, on the second or the third day the embryos are transferred following the egg retrieval at the four to eight cell stages. For two or three more days, the IVF embryos must continue to grow so that it reaches the blastocyst transfer stage (50-150 cells) before they are ready for the implantation into the endometrium or the uterine wall. Recent advances in IVF laboratory treatments have allowed for the successful culture of embryos to the blastocyst stage.
What is Blastocyst Transfer?
Blastocysts are an advanced embryo which is developed for about five to six days after the fertilization. There are two different types of cells and central cavity in the blastocysts. Healthy blastocysts should begin hatching from the outer shell known as the zona pellucid by end of the sixth day. It will be implanted into the lining of the mother’s uterus within 24 hours of hatching.
Why Choose Blastocyst Transfer?
Blastocyst transfer is preferred by many fertility specialists because it increases the chances of successful implantation compared to earlier-stage embryo transfers. Here’s why:
- Higher implantation potential: At the four- to eight-cell stage, many embryos may stop developing due to inherent problems. By allowing embryos to develop to the blastocyst stage, those that survive are often more robust and developmentally competent, increasing their implantation potential
- Natural Development Timing: When transferred at the blastocyst stage, the embryo is at the ideal stage for uterine implantation, similar to the timing of natural conception.
Benefits of Blastocyst Transfer
- Improved Embryo Selection: Culturing embryos to the blastocyst stage allows embryologists to select the most viable embryos, increasing the chances of pregnancy.
- Higher Success Rates: Blastocyst transfer is associated with a higher success rate, around 50-60%, compared to earlier-stage transfers.
- Reduced Risk of Multiple Pregnancies: Transferring fewer, but higher-quality, embryos can reduce the likelihood of multiple pregnancies.
Potential Drawbacks
- Lower Embryo Survival: Not all embryos will survive to the blastocyst stage, with only about 30-50% reaching this point.
- Risk of No Transferable Embryos: In some cases, no embryos may develop to the blastocyst stage, resulting in no embryos available for transfer.
Who is eligible for Blastocyst Embryo Transfer?
Couples who have had unsuccessful prior attempts with ICSI ( Intracytoplasmic Sperm Injection. ) despite having many good quality eggs retrieved are being offered blastocyst culture as an alternative treatment. The ability to select the most viable embryos for transfer & implantation should improve their chance of achieving a pregnancy.
In the IVF laboratory, the embryos are cultured for 5 days after the egg retrieval. At least 5 good quality embryos (six to eight cells) should be available on the 3rd day after the egg retrieval so as to maximize the chances of obtaining a blastocyst.
Final Thoughts
Blastocyst transfer is a promising option for many couples undergoing IVF, but it may not be suitable for everyone. Consult your fertility specialist to determine if this approach is right for you.
