Embryo selection in IVF: What you need to know

In vitro fertilization (IVF) refers to a type of assisted reproductive technology (ART) where sperm and an egg are fertilized outside the human body.

The highly skilled doctors at the best infertility clinic in Kolkata tell us about the process of embryo selection in IVF.

Embryo selection

Embryo selection in IVF is an important aspect of the process that aims at identifying the most viable embryos for transfer into the uterus. Here is a breakdown of how embryo selection normally occurs:

• Embryo development monitoring

After the eggs are retrieved from the female's ovaries and inseminated in a laboratory, the resulting embryos are cultured and monitored. Embryologists observe their development closely, assessing factors like cell division rate, symmetry and fragmentation.

• Embryo grading

Embryos are graded on the basis of their appearance and stage of development. Grading systems may vary but in general, embryos with uniform cell division, minimal fragmentation and appropriate size are considered higher quality and expected to implant successfully.

• Monitoring

Embryo development is monitored continuously, which permits embryologists to observe minute alterations in embryo development patterns over time. This may provide additional insights regarding embryo quality and viability. The best IVF clinic in Kolkata offers cutting-edge technologies and compassionate care to achieve positive results.

• Preimplantation Genetic Testing (PGT)

In some instances, embryos may undergo the process of PGT to screen for chromosomal abnormalities or genetic disorders. 

• Use of Artificial Intelligence Platforms 

The aim is to identify the embryos which possess the greatest potential for implantation and healthy pregnancy while lowering the risk of multiple pregnancies.

• Decision of transfer

Based on embryo quality and other relevant factors, the number and timing of embryo transfers ( usually Day 3 or 5 ) are decided. In some cases, one embryo may be transferred to lower the risk of multiple pregnancies, while on the other hand, multiple embryos may be transferred to optimize the success rate.

• Frozen Embryo Transfer (FET)

Embryos that are not transferred immediately after fertilization may be cryopreserved (frozen) for use in the future. Frozen embryo transfer (FET) permits accurate timing of embryo transfer and can result in higher success rates compared to fresh embryo transfer in certain scenarios.

Conclusion

To conclude, embryo selection in IVF involves a cautious assessment of several factors to maximize the possibilities of a successful pregnancy. The best infertility clinic in Kolkata treats infertility issues in women with precision.
