For those considering IVF or egg freezing, choosing the right medical technology and a professional team is the key to success. Some social media channels or unqualified agencies may spread misconceptions, such as “older patients or those with poor ovarian function can skip blastocyst culture and PGT testing, and go straight to transfer.” Such claims often come from doctors or labs with limited technical capacity. Medical guidelines clearly emphasize that undergoing IVF-PGT is a necessary step to improve success rates.

 

Why not stop at IVF-ICSI?

 

1. The limitations of day-3 embryo transfer

   Some doctors still recommend transferring embryos on day 3 without further culture. However, the process of culturing embryos in vitro is itself a natural selection process. Only embryos with strong developmental potential can reach the blastocyst stage on day 5 or day 6. If transfer is done at day 3, unhealthy embryos that should have been eliminated may be implanted instead, lowering implantation rates and increasing miscarriage risks.

 

2. The importance of PGT testing

   PGT (Preimplantation Genetic Testing) is the core of IVF-PGT. It allows the selection of embryos with normal chromosomes, which is especially critical for older women or families with genetic risks.

 

Without PGT, even embryos that look “high-quality” under the microscope may carry chromosomal abnormalities, leading to failed implantation or early miscarriage. Skipping PGT means giving up the chance to rule out most genetic risks in advance—a costly waste of time, money, and emotional energy.

 

How to choose a truly professional IVF clinic?

 

Even when IVF-PGT is requested, there are still huge differences between clinics.

 

1. The principle of “blastocyst culture + PGT”

   The simplest way to judge professionalism is whether a clinic insists on both blastocyst culture and PGT. If a doctor claims there is little difference between ICSI and IVF-PGT, or suggests skipping PGT, it likely reflects a lack of laboratory capability or clinical expertise.

 

2. Physician expertise and lab quality

   IVF success rates largely depend on the doctor’s skills and the lab’s standards. Just like in professional competitions, even small differences in experience and technique can lead to drastically different results. An experienced doctor can tailor stimulation protocols based on hormone levels and ovarian response, while a top lab ensures accurate blastocyst culture and PGT testing.
