Patient's question:
Is it necessary to culture embryos to the blastocyst stage for IVF to the US? Isn't it okay if they aren't? What kind of help do you care about: Is it necessary to culture embryos to the blastocyst stage for IVF to the US?Doctor's answer:
US IVF Doctor: It is highly necessary. The blastocyst is cultured for an additional two days compared to the early embryo, following the natural law of survival of the fittest to eliminate those with poor quality and lower developmental potential. This can enhance implantation rates. The fifth-day blastocyst is the optimal state of in vitro embryo culture; rushing it too early or too late can interfere with embryo quality and implantation rates. The blastocyst is composed of over 100 cells, with more stable structure and morphology, and is significantly larger than early embryos with 8-12 cells. It is easier to adapt to the maternal environment after grafting and achieve successful implantation, reducing the risk of ectopic pregnancy. Additionally, it is required for the genetic screening confirmation of US third-generation IVF. The blastocyst clearly differentiates into inner and outer cell layers. US DreamMakers HRC experts perform cell extraction from the outer layer (which will develop into the placenta) to operate the PGS/PGD genetic screening confirmation technology, ensuring the complete protection of the future fetus's health.
