In the IVF cycle, the embryo score is a great concern for patients, and when the embryo score is low, patients tend to feel disappointed and anxious. So, do low-scoring embryos still have a chance to succeed?
Let's first understand the embryo score:
The scoring of embryos is based on a number of factors, including the number, size and shape of blastomeres, whether the cytoplasm is homogeneous, whether there is a granular phenomenon, how much debris is, etc.
Based on these indicators, embryos are classified into different grades:
The first-order embryo is the same size as the blastomere, the morphology is regular, the cytoplasm is uniform and clear, there is no granular phenomenon, and the fragments are no or less than 10%.
The secondary embryo is slightly unequal to the blastomere, the morphology is irregular, the cytoplasm may have granular phenomena, and the fragments are 10% to 20%.
* The embryo is an epiblastomere with uneven size and irregular morphology, and the cytoplasm may have obvious granules, with fragments of 20% to 50%.
Fourth-order embryos are severely uneven in size of blastomeres, and the cytoplasm may have severe granularity, with fragments greater than 50%.
PS: The first and second level embryos belong to high-quality embryos, ** embryos belong to usable embryos, and the fourth level embryos generally do not need to be transferred.
Of course, it is important to understand here that the embryo score does not fully ** the developmental potential of the embryo, although the score of high-quality embryos is usually higher, but the embryo with a low score does not necessarily mean that they have no developmental potential. Therefore, even if the embryo score is low, we cannot easily give up hope.
Secondly, there are many factors that affect the success rate of IVF, not only the score of the embryo, but also the patient's age, uterine environment, hormone levels and other factors will have an impact on the success rate, so even if the embryo score is low, we can improve the success rate by improving other factors.
Therefore, even if the embryo score is low, we can not easily give up hope, IVF is a complex project, which requires the joint efforts of doctors and patients, in the face of low-scoring embryos, we should fully communicate with doctors, understand the condition of the embryo and their own physical condition, and jointly develop a suitable transfer plan, at the same time, we must also maintain a positive attitude and believe that our body and the doctor's efforts can create miracles.
