What are the improvements of the third generation of IVF
IVF is a kind of assisted reproductive technology in vitro fertilization, which is widely used to treat infertility patients. With the continuous development of science and technology, IVF technology is also constantly updated and improved. What are the improvements of the third generation IVF technology compared with the previous two generations? This article will elaborate from four aspects.
1. Supernova diagnosis improves embryo quality assessment
The third generation IVF technology introduced the supernova diagnosis technology, which is a method to evaluate the potential genetic defects of embryos through gene sequencing and bioinformatics analysis. In traditional IVF technology, doctors usually select the implanted embryos according to the appearance and development of the embryos. Supernova diagnostic technology can screen embryos with potential genetic defects by analyzing the genomic information of embryonic cells at the early stage of fertilized egg development, which improves the accuracy of embryo quality assessment.
Supernova diagnostic technology has been widely used in some internationally renowned hospitals, such as the University of Massachusetts School of Medicine in the United States, Cambridge University in the United Kingdom, and Peking Union Medical College Hospital in China. It can not only improve the success rate of IVF, but also avoid the implantation of embryos with genetic diseases, and reduce the risk of miscarriage in early pregnancy and abnormal birth.
2. In vitro maturation technology increases the number of eggs collected
The third generation IVF technology has introduced in vitro follicle maturation technology, also known as IVM technology. This is a method of acquiring immature follicles and promoting follicular maturation by stimulating ovaries in vitro. In the traditional IVF technology, only mature eggs after ovulation can be collected. IVM technology can obtain more immature follicles through in vitro growth, and promote these follicles to mature in the laboratory, thus increasing the number of eggs collected.
In vitro maturation technology has been mainly applied in advanced assisted reproductive hospitals such as London Women's Clinic in the UK and Melbourne Test Tube Baby Center in Australia. This technology can not only improve the success rate of IVF, but also avoid ovarian hyperstimulation syndrome caused by excessive drug stimulation.
3. Surrogate technology improves fertility opportunities of infertile couples
The third generation IVF technology also includes surrogacy technology, also known as in vitro fertilization embryo transfer technology. This is a method that allows the surrogate woman to help the fetus develop until delivery by combining the sperm and eggs of both husband and wife in the womb of the surrogate woman. Surrogate technology is applicable to some infertile couples where women are unable to conceive or maintain pregnancy.
Surrogation technology has been widely used in California Reproductive Center in the United States, Delhi IVF Center in India and other places. Through surrogacy technology, infertile couples can realize their reproductive dreams and avoid the problems of poor pregnancy and childbirth caused by uterine malformations, multiple abortions and other reasons.
4. In vitro fertilization technology improves the success rate of IVF
In vitro fertilization (IVF) in the third generation IVF technology is a method that combines sperm and egg in vitro in the laboratory and transfers the fertilized egg back to the mother. In traditional IVF technology, fertilized eggs are usually cultured in petri dishes for 2-3 days, and then the best one or two embryos are selected for transfer. However, the third generation IVF technology has adopted such improvement measures as cryopreservation and prolongation of culture time, so that embryos can reach a higher development stage in vitro.
In vitro fertilization (IVF) technology has been widely used in world famous hospitals such as the Union Medical College in Tokyo, Japan, and the Johns Hopkins University School of Medicine in the United States. The improvement of the third generation IVF technology has improved the success rate of IVF and reduced the harm to the mother's body.
summary
The third generation IVF technology has effectively improved the success rate of IVF, reduced the risk of genetic diseases and provided more fertility opportunities for many infertile couples through the improvement of supernova diagnosis, in vitro maturation, surrogacy and in vitro fertilization. With the continuous progress of science and technology, it is believed that there will be more breakthroughs and improvements in IVF technology in the future.
