When doing IVF, the number of eggs retrieved and the number of embryos are often a tangled topic, some people get a considerable number of eggs, but the final embryos are extremely rare, which makes people very upset and confused. Why?
First of all, the eggs obtained by IVF are not necessarily all mature and available, some are even empty eggs, the maturity rate is generally about 80%, only mature eggs can be fertilized, if the patient suffers from some other gynecological diseases, such as polycystic, premature aging, etc., the maturity rate will be lower.
Second, successfully fertilized fertilized eggs do not guarantee that each one will be successfully ripped, the egg cleavage rate is generally more than 95%, and the fertilized eggs with unsuccessful cleavage cannot be used successfully.
Third, even if the egg is fertilized and the egg is cracked, the quality of the developed embryos is good and bad, and only high-quality embryos can be transferred and frozen, and the general rate of high-quality embryos is about 50%.
In summary, it is not that as many eggs as there are, there will be many embryos in the end. There are individual patients who have a significant decrease in fertilization rate, egg cleavage rate, and high-quality embryo rate due to poor egg quality or sperm quality problems, and sometimes even no good embryos are available for transfer.
For IVF mothers who have completed egg retrieval, it is recommended:
Now that the eggs have been taken and the embryos have been cultivated, don't dwell on how many eggs you have taken and how many embryos you have cultivated. Focus on adjusting your physical condition, preparing for the next transfer, and providing better physical conditions for embryo implantation.
For IVMs who are about to enter the cycle, it is recommended:
I hope that you will follow the doctor's advice, develop good living habits and exercise regularly, which will help improve your egg acquisition and embryo culture success rate.
For parents who are considering whether to become pregnant with IVF:
I hope you can understand that no matter how advanced the technology, no matter how clever the doctor, can only "watch the dishes and eat", age is the key factor affecting your fertility! Instead of constantly hesitating whether you should use IVF technology to help conceive, you should go directly to a regular fertility center to check your fertility and let a professional doctor customize the best pregnancy/fertility plan for you!
