Patient's question:
Hello, my wife and I have been married for many years without having children. We are undergoing IVF treatment. Today, the hospital said the embryo is at the 7c stage. What is the success rate?Doctor's answer:
Clinically, there is no statistical data available, so the main focus is on implantation. Because if implantation does not occur, even a high number of dividing cells is useless. The ability to be transplanted proves that it is a qualified embryo.An embryo is not only evaluated based on cell count but also on its grade. The best three-day-old embryo is 8 cells, Grade 1, followed by 8 cells, Grade 2, and then 7 cells, Grade 1. During the cleavage stage, embryos that quickly divide into 8, 10, or 12 cells are generally considered healthy. The blastomeres should be smooth, uniform, without roughness or granularity. The blastomeres should be oval-shaped, symmetrical, and connected to other blastomeres. Round or fragmented embryos can only be transplanted when the ideal number is needed.
Each blastomere has only one nucleus, which has a clear structure and cannot have two or be unclear.
