Patient's question:
I retrieved 20 eggs today and learned that 12 were fertilized. Among them, 10 developed into 8-cell embryos, 1 into a 7-cell embryo, and 1 into a 6-cell embryo. However, only one was an 8-cell grade A, while the rest were 8-cell grade B. Is the implantation rate of 8-cell grade B embryos high?Doctor's answer:
All 8 cells are good. The embryos formed before the IVF transfer are categorized based on their quality into Grade 1 and Grade 2. Grade 1 embryos are of higher quality and have a higher success rate after transfer. Grade 2 embryos have lower quality and may reduce the success rate of IVF transfer. It is recommended that you relax and choose a reasonable embryo for transfer under the guidance of your doctor to improve the chances of pregnancy.
