What are the benefits of fresh embryo transfer?

When women reach a certain age, they all hope to conceive successfully. However, due to various reasons, women's bodies may have problems, such as inability to conceive and diseases. In order to deal with these conditions in a timely manner, women must be treated in a scientific way. If necessary, they can also undergo in vitro fertilization. However, many people tend to prefer fresh embryo transplantation. So what are the benefits of fresh embryo transplantation?

First, what are the benefits of fresh embryo transfer? Blastocyst culture is an important technology in assisted reproductive technology. Generally speaking, blastocyst is the final stage of embryo culture in vitro, which is usually formed on the 5th day after the egg is fertilized. During natural conception, the embryo develops in the fallopian tube and implants into the mother in the form of a blastocyst. Therefore, blastocyst transfer in in vitro fertilization treatment can achieve a higher embryo implantation rate.

Second, generally speaking, the patients who are suitable for IVF blastocyst transfer are mainly: 1. Patients under 35 years old who respond well to ovulation induction treatment, with ≥12~15 eggs retrieved and ≥5~8 high-quality embryos at the 6~8 cell stage, who are expected to be successfully cultured to obtain blastocysts. In order to optimize embryo selection, reduce the number of transferred embryos, reduce multiple pregnancies, and improve embryo implantation rate, blastocyst culture is performed. 2. Patients who have failed multiple IVF treatments for unknown reasons (more than 3 times), those whose embryos have good quality but implantation has failed, and those who are suspected of having limited embryo development potential. 3. Patients who need embryo biopsy, such as PGD (chromosomal abnormality) patients, will undergo blastocyst culture after biopsy to wait for the PGD results.

What are the benefits of fresh embryo transfer? Stimulating the developmental potential of the embryo: Whether the embryo can develop into a blastocyst is related to its own genes. When the embryo has no developmental potential or carries abnormal chromosomes and genes, it may be naturally eliminated due to its own developmental abnormalities during the extended culture process. Only the embryos with the best quality can develop into blastocysts. Embryo development is more synchronized with the endometrium: Blastocyst stage transfer can provide a natural environment that is closer to reproductive physiology and has a higher implantation ability.
