Blastocyst culture involves growing embryos in the lab for 5–6 days until they reach the blastocyst stage (100+ cells), compared to cleavage-stage transfer (day 3, 6–8 cells).
Why It Matters
Improved Selection: Only the strongest embryos reach the blastocyst stage, allowing us to select those with the highest implantation potential.
Better Timing: Transfer aligns with the uterus’s natural receptivity window.
Fewer Embryos Transferred: Reduces the risk of multiple pregnancies.
Who It’s For
Younger patients (<37) with a good ovarian response.
Couples undergoing preimplantation genetic testing (PGT).
Patients with multiple embryos to select from.
Risks
Not all embryos reach the blastocyst stage, potentially reducing the number available for transfer or freezing.
No significant increase in overall live birth rates compared to cleavage-stage transfer in all cases.
Cost
Included in the standard IVF cycle cost.
Our Approach
Our lab uses time-lapse incubators to monitor embryo development continuously, ensuring optimal conditions. We discuss transfer options with you to balance success and safety.
