In standard IVF, embryos were traditionally transferred on Day 2 or Day 3 at the 4 to 8-cell cleavage stage. Blastocyst culture is an advanced embryology protocol where embryos are nurtured in specialized sequential culture media inside tri-gas benchtop incubators until Day 5 or Day 6, reaching the blastocyst stage (over 100 to 150 cells).
Reaching the blastocyst stage is a critical biological hurdle: only chromosomally competent embryos with strong developmental potential survive to Day 5. This natural selection allows Dr. Vandana Mishra to perform Single Embryo Transfers (eSET), eliminating twin risks while achieving peak pregnancy success.
World-class embryology facilities, individualized clinical protocols, and transparent ethical care right here in Patna.
Only the strongest embryos with active embryonic genomes survive to blastocyst stage.
Each top-grade blastocyst has significantly higher attachment potential than Day-3 embryos.
Achieve high pregnancy rates transferring just one embryo, eliminating twin/triplet risks.
Trophectoderm biopsy on Day-5 does not damage the inner cell mass that forms the baby.
Individual incubation chambers with low physiological oxygen mimicking human fallopian tubes.
Detailed scoring of Inner Cell Mass (ICM) and Trophectoderm for precise embryo selection.
Clear, structured milestones at every phase of your personalized fertility journey.
Embryologists confirm normal fertilization by checking for two pronuclei (2PN) 16-18 hours post-IVF/ICSI.
Embryos are checked for 6-8 uniform cells with minimal fragmentation and placed in fresh blastocyst media.
Cells begin to compact and fuse together, activating the embryonic genome and preparing for cavitation.
Embryo expands to 100+ cells, differentiating into the Inner Cell Mass (fetus) and Trophectoderm (placenta).
Senior embryologist grades expansion (1-6), ICM quality (A-C), and trophectoderm quality (A-C).
The single best blastocyst is selected for transfer; surplus high-grade blastocysts are safely vitrified.
At Good News IVF, every blastocyst is evaluated under high-resolution optics using the internationally recognized Gardner grading system. For example, a grade of "4AA" signifies a fully expanded blastocyst with an exceptional inner cell mass (future baby) and high-density trophectoderm (future placenta), carrying the highest clinical implantation odds.
