Extended embryo culture to Day 5–6 (blastocyst stage) rather than traditional Day 3 transfer, allowing natural selection of embryos with higher developmental potential.
Utilizing advanced technologies, achieves a high blastulation rate of 72.5% and IVF pregnancy rates of 70-80%. This involves culturing embryos to the blastocyst stage (5-6 days old with distinct cell types) before transfer, which allows for fewer embryos to be transferred and thus reduces the risk of multiple pregnancies.
Why It Matters
Not all embryos reach blastocyst stage—and those that do have significantly higher implantation rates per transfer. Extended culture also enables:
- Better synchronization with endometrial receptivity window
- More accurate morphological grading
- Eligibility for PGT testing (which requires blastocyst-stage biopsy)
- Higher cumulative live birth rates per retrieval cycle
The Alpha Advantage
Our lab maintains optimized sequential culture media and stable environmental conditions specifically validated for extended culture success in Filipino patient populations. We provide transparent blastocyst development data so you understand your individual outcomes.
