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. Could you please tell me what the success rate is?Doctor's answer:
Clinically, there is no statistical data; it mainly depends on the implantation situation. 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.When evaluating embryos, it's not just about the cells; the grade is also important. 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. Circular or fragmented embryos can only be transplanted when the ideal number is needed.
Each blastomere should have only one nucleus with clear structure and cannot have two or unclear structure.
