Can Guilin IVF Adjust Embryo Chromosome Number?

IVF technology is a way to help couples who cannot conceive naturally to achieve their reproductive aspirations. Guilin is one of the famous IVF centers in China, but there are some disputes about whether the technology of Guilin IVF can adjust the chromosome number of embryos. This article will elaborate from four aspects.

The concept of embryo chromosome number adjustment

The regulation of embryo chromosome number refers to the regulation of embryo chromosome number by technical means in the process of IVF. Normally, human cells have 23 pairs of chromosomes, one of which is a sex chromosome, and the other 22 are non sex chromosomes. The abnormal number of chromosomes in the embryo will lead to abnormal development of the embryo or embryo implantation failure. The purpose of embryo chromosome number adjustment is to screen out embryos with normal chromosomes and increase the probability of successful pregnancy of IVF.

Chromosome screening techniques for test tube infants in Guilin

There are mainly two kinds of chromosome screening technologies adopted by Guilin IVF Center: the first is the electric field ovary in vitro maturation (ef ivm) technology, and the second is the next generation high-throughput gene sequencing (NGS) technology.

Ef ivm technology is to fertilize mature oocytes and sperm in vitro, and then after a certain culture time, when they develop to 6-8 cell stage, use a charged field to screen the chromosomes of the embryo. This technology can screen embryos with healthy and normal chromosomes according to the different charges of chromosomes.

NGS technology is to detect the chromosome number of embryos and whether there are chromosomal abnormalities by high-throughput sequencing of DNA in embryonic cells. This technique has high sensitivity and accuracy, and can effectively screen embryos with normal chromosomes.

Feasibility of chromosome number adjustment in Guilin IVF embryos

At present, the chromosome screening technology adopted by Guilin IVF Center can help couples screen embryos with normal chromosomes, thus improving the success rate of IVF. However, this technique cannot directly adjust the chromosome number of embryos.

The chromosome number of an embryo is determined by the chromosome combination of sperm and egg in the process of fertilization. IVF technology can only select embryos with normal chromosome number for transplantation, and cannot change the chromosome number of the embryo itself.

Therefore, Guilin IVF only improved the selection rate of embryos with normal chromosomes through screening technology, but did not realize the adjustment of embryo chromosome number.

summary

In Guilin IVF Center, advanced chromosome screening technology is adopted, but the chromosome number of embryos cannot be directly adjusted. By screening embryos with normal chromosomes, we can improve the success rate of IVF and help couples who cannot conceive naturally achieve their fertility aspirations. However, the embryo chromosome number adjustment technology is still in the research stage, and there are no concrete results at present. For embryos with abnormal chromosome numbers, Guilin IVF Center will provide professional consultation and support to help couples make reasonable decisions.
