Is the quality of embryos important to IVF?
In vitro fertilization, IVF) is an assisted reproductive technology, which enables many infertile couples to realize their reproductive dreams. In the process of IVF, as an important biological material, the quality of embryos plays a vital role in the successful pregnancy and the production of high-quality babies. This article will elaborate on the impact of embryo quality on IVF, related screening technologies, hospitals and quality control of embryo quality requirements.
1. Effect of embryo quality on IVF
Embryo quality is directly related to the success rate of IVF pregnancy and infant quality. First of all, high-quality embryos have higher implantation capacity, can be successfully embedded into the endometrium, and achieve pregnancy. Secondly, the chromosome number and structure of high-quality embryos are normal, which reduces the risk of abnormal embryonic development and genetic diseases carried by embryos. In addition, good embryo quality is also closely related to pregnancy rate, abortion rate and neonatal success rate.
In order to evaluate the quality of the embryo, doctors usually consider the appearance, cell division and chromosome status of the embryo. The most commonly used assessment indicators include embryo division speed, particle size of cytoplasmic contents, chromosome number and shape, etc. According to the evaluation results, doctors can select embryos with high embryonic quality for transplantation to improve the success rate of pregnancy.
Some studies have shown that by introducing embryo screening technology, such as single cell karyotype testing for aneuploid, PGT-A）， It can further screen high-quality embryos and improve the success rate of IVF. This technology can detect chromosomal abnormalities in embryos, reduce embryo transfer with chromosomal abnormalities, and thus reduce the risk of abortion.
2. Relevant screening techniques
In order to select high-quality embryos for transplantation, doctors can use some screening techniques to evaluate the quality of embryos. In addition to the above-mentioned PGT-A, there are some other screening technologies that can be used, such as PGT-M and PGT-SR.
PGT-M is mainly used to detect embryos carrying single gene disease. Through genetic analysis of embryos, embryos carrying genetic disease gene mutations can be screened to avoid passing on genetic diseases to the next generation.
PGT-SR is mainly used to screen structural chromosomal abnormalities of embryos. It can detect structural defects of embryonic chromosomes, such as inversion, balanced translocation or chromosome segment deletion. When the embryo carries these abnormalities, it may lead to embryonic development difficulties or abortion.
3. Hospital with embryo quality requirements
In the field of IVF, Linfen Reproductive Medicine Center is a hospital with high reputation. It has advanced IVF technology and professional medical team, and is committed to providing high-quality assisted reproductive services for infertile couples.
Linfen Reproductive Medicine Center has introduced internationally advanced embryo screening technologies, such as PGT-A PGT-M and PGT-SR can evaluate the quality and genetic status of embryos and select the best embryos for patients to transfer. At the same time, Linfen Reproductive Medicine Center also pays attention to quality control to ensure that the culture environment, transfer process and postoperative care of embryos meet the standards and improve the success rate of IVF.
4. Quality control
In order to ensure the quality of IVF embryos, hospitals need strict quality control throughout the IVF process.
First, hospitals need to ensure a stable environment for embryo culture and provide appropriate culture media and nutrients. These conditions play a vital role in the normal development of embryos.
Secondly, the transplant process requires experienced doctors and skilled surgical skills. Doctors should accurately capture the best time for embryo transfer and ensure that the embryo is not injured during the transfer process.
Finally, postoperative nursing is also an important part of quality control. The hospital should provide a good nursing environment and personalized nursing programs to help patients get through pregnancy, and monitor the growth of embryos.
summary
In conclusion, embryo quality has an important impact on the success rate and infant quality of IVF. By combining with embryo screening technology, doctors can screen high-quality embryos and improve the success rate of IVF. In Linfen Reproductive Medicine Center and other related hospitals, strict quality control measures were taken to ensure the standardization and efficiency of each link in the IVF process. It is very important to select hospitals and evaluate embryo quality when seeking IVF technical assistance.
