Blastocyst Transfer

BLASTOCYST TRANSFER

What is Blastocyst Transfer?

Blastocyst transfer is an advanced IVF technique where a fertilized embryo is allowed to develop in the lab for 5 to 6 days until it reaches the blastocyst stage – a phase where it forms a fluid-filled cavity and becomes more structured. Once matured, one or more blastocysts are transferred into the woman’s uterus to enhance the chances of implantation and pregnancy.

The process begins with egg retrieval, followed by fertilization using IVF or ICSI. The resulting embryos are cultured in an incubator until day 5 or 6. At this stage, only the best quality embryos that have successfully reached the blastocyst phase are chosen for transfer.

When to Consider Blastocyte Transfer?

Blastocysts have a higher potential for implantation and successful pregnancy compared to embryos transferred at earlier stages. This is because they are more developed and have already undergone natural selection, which increases their chances of survival and growth.

Benefits of Blastocyst Transfer

Higher implantation and pregnancy rates
Allows selection of the best quality embryos
Better synchronization with the uterine lining
Reduced risk of multiple pregnancies by enabling single embryo transfer

Conclusion

Blastocyst transfer significantly improves the chances of conception -especially in women under 35, where success rates can range from 45% to 50%. For women aged 35 to 40, the success rate is around 35% to 40%. However, this method may not be ideal for those with a low egg reserve, as not all embryos may reach the blastocyst stage. In such cases, earlier embryo transfer may be recommended for better outcomes.
