For intended parents considering IVF or egg freezing, choosing the right medical technology and professional team is key to success. Currently, some self-media or non-professional agencies may spread misconceptions, such as claiming that "older individuals with poor ovarian function can skip blastocyst culture and PGT testing and proceed directly to transfer." This claim is often a justification from doctors or labs lacking sufficient technical expertise. Medical frontiers clearly mandate that performing IVF-PGT is a necessary step to enhance success rates.
Why You Cannot Stop at Second-Generation IVF
1. Limitations of Day 3 Embryo Transfer
Some doctors still recommend transferring Day 3 embryos without further culture. However, the in-vitro embryo culture process is, in itself, an important selection process. Only those embryos with enough vitality can develop to the Day 5 or Day 6 blastocyst stage in the lab environment. If transfer is performed on Day 3, unhealthy embryos that should have been naturally eliminated may be implanted, which not only lowers the implantation rate but also increases the risk of miscarriage.
2. The Importance of PGT Testing
PGT (Preimplantation Genetic Testing) is the core of third-generation IVF, as it screens for chromosomally normal embryos. This is especially crucial for advanced maternal age couples or families with genetic risks.
Without PGT testing, even embryos that look "excellent" may carry chromosomal abnormalities, leading to failed transfers or early miscarriages. Therefore, foregoing PGT testing means missing the opportunity to proactively rule out most genetic risks—a significant waste of time, money, and emotional energy.
How to Choose a Truly Professional IVF Clinic
Even when third-generation IVF is explicitly required, there can still be significant differences in standards among various medical institutions.
1. Insist on the "Blastocyst Culture + PGT" Principle
The most direct way to judge a clinic's professionalism is to see if they insist on both blastocyst culture and PGT testing. If a doctor claims that second-generation IVF and third-generation have comparable success rates or suggests skipping PGT, it may indicate that their lab or medical team lacks the professional capability to perform IVF-PGT.
2. Doctor's Experience and Technique
The variation in IVF success rates largely depends on the skill of the doctor and the lab. Just like top players in a professional sport, even within the same field, small differences in technique and experience can lead to vastly different outcomes. An experienced doctor can formulate a more precise stimulation protocol based on the patient's hormone levels and ovarian response, and an excellent lab can ensure the accuracy of blastocyst culture and PGT testing.
