Advantages and characteristics of polyspermy in IVF technology
IVF technology is a medical technology. Through artificial assisted reproduction technology, couples who cannot conceive naturally can have their own children. In IVF technology, polyspermy is an important step, which can play an important role in improving pregnancy rate and embryo development quality. This article will discuss the advantages and characteristics of polyspermy.
Improve pregnancy rate
Multi sperm penetration into the egg refers to the injection of multiple sperm into the embryo precursor cell (oocyte), and the combination of one or more sperm with the egg through the oocyte cytoplasm, thus forming a fertilized egg. Compared with conventional single sperm injection, multiple sperm injection can improve the pregnancy rate. First of all, multiple sperm can increase the number of fertilized eggs, thus increasing the success rate. Secondly, the best fertilized eggs can be selected selectively by multi sperm penetration. Because each sperm has different genetic information and development ability, only the best sperm can successfully combine through competition, thus producing a healthier embryo.
In addition, polyspermy can also provide more options to meet the needs of patients. For older women or couples with different degrees of infertility, the success rate may be low. However, the number of fertilized eggs can be increased and the probability of pregnancy can be improved by multi sperm penetration. If the early fertilized eggs develop smoothly, you can also choose to carry out embryo single nucleotide polymorphism (SNP) detection, screen healthy embryos, and select the best quality embryos for transplantation to further improve the success rate of IVF.
Improvement of embryo development quality
The quality of embryo development can be improved by polyspermy. This is because polyspermy can increase the number of embryonic cells and promote early embryonic development. In addition, the participation of multiple spermatozoa can cause a series of egg cell reactions and activate the expression of some genes, which may have a positive impact on the quality of embryos. In addition, polyspermy can also provide more genetic selection, select healthier embryos for transplantation, and reduce the risk of embryo malformation and disease.
At the same time, polyspermy can help doctors judge the quality of eggs more accurately. Through the combination of sperm and egg cell, doctors can observe the combination of different degrees, and evaluate its quality in combination with the morphological characteristics of egg cell. This is of great significance for screening the best embryos before transplantation.
Directional selectivity
Multiple insemination eggs also have the advantage of directional selectivity in IVF technology. Through the participation and competition of multiple spermatozoa, only spermatozoa with high developmental ability and high-quality genes can successfully combine, thus optimizing the genetic quality of embryos. This selectively improves the overall quality of the embryo and its excellent genetic characteristics.
In addition, multi sperm insemination technology can also provide more genetic selection to increase embryo quality. For example, if the parents have genetic diseases or chromosome abnormalities, polysperm eggs can select healthy embryos for transplantation through selection to reduce the risk of disease in the next generation.
Summary
As an important step in IVF technology, polyspermy has the characteristics and advantages of improving pregnancy rate, improving embryo development quality, and targeting selectivity. The number of fertilized eggs can be increased and the success rate of IVF can be improved by polyspermy. In addition, high-quality embryos can be selected through polyspermy, reducing the risk of embryo malformation and disease, and providing the possibility for couples to have healthy children. In conclusion, multiple sperm insemination technology has an important application prospect in IVF technology.
