Families who have learned about IVF fertility are well aware that if the early pregnancy preparation is in place and high-quality sperm eggs are obtained, it is very beneficial for the formation of high-grade embryos after the IVF is completed. Does this mean that embryo transfer is relatively high? What is the relationship between IVF embryo grade and success rate? Is it positively correlated? Specific and listen to Hengjian Overseas for your detailed analysis!
What is the relationship between IVF embryo grade and success rate?
The success rate of IVF has a lot to do with the quality of the embryo, and the quality of the embryo has a lot to do with the quality of the sperm and eggs, and the success rate of the transfer of high-quality embryos will be greatly improved, and the high-quality embryos are also higher-grade embryos.
What do the advantages of performing IVF embryo ratings do?
1. In order to reduce the risk of transplant failure or miscarriage.
2. Can help test tube parents-to-be save valuable time, energy and money.
3. Survival of the fittest. The key element of the process of classifying embryos, if you want to distinguish the embryo level, you need to let the egg and sperm to form a fertilized egg; then further split development; on the 1st to 3rd day after the fertilized egg constitutes the embryo, it is called the embryo of the cleft stage; the embryo of the 5th to 6th day is called the blastocyst.
How is the embryo grade divided? Test tube family to understand
Class I embryos: equal cell size, translucent, cytoplasmic particle-free, fragments 0%-5%
Grade II embryos: slightly uneven cell size, particle phenomenon in cytoplasm, 6%-20% debris
Grade III embryos: the cell size is obviously uneven, the cytoplasm has obvious particle phenomenon, and the fragments are 21%-50%.
Grade IV embryos: severely uneven cell sizes, severe particles in the cytoplasm, 50% debris >
Are IVF 45-day embryos stable?
The first three months after a successful IVF transplant are a critical period, and spending this time safely can be called "surviving the dangerous period", which is actually the same as natural pregnancy. Hengjian Overseas pointed out that in other words, the IVF embryo transfer in the third month of pregnancy is stable. But nothing is absolute, and naturally there are exceptions, especially for older or healthier female friends, who usually need to ensure a smooth pregnancy through fetal preservation.
Note: Progesterone is generally needed to support conception in the first trimester after transplantation and to use progesterone as directed by a physician. 14 days after the transplant surgery to go to the hospital on an empty stomach to draw blood to measure serum HCG, generally greater than 50miu / ml indicates pregnancy, continue fetal treatment for 2-3 weeks after doing B ultrasound examination, to determine whether intrauterine pregnancy, there are fetal buds, fetal heart, that can determine clinical pregnancy.
Warm tips: If you have a history of bad miscarriage, scarring the uterus, uterine laxity of the friends or to pay attention to, there are pregnancy complications should also go to the obstetrics department in time to follow up.
