Development trend and new progress of IVF technology
IVF technology is an assisted reproductive technology, which helps couples who cannot conceive naturally to achieve their reproductive aspirations through in vitro fertilization (IVF). With the continuous progress of science and technology, IVF technology is also developing and improving. This article will elaborate on the development trend and new progress of IVF technology from four aspects.
1. Embryo selection technology
With the development of gene sequencing technology, embryo selection technology is more and more widely used in the process of IVF. Embryo selection technology can screen embryos without genetic diseases and certain genetic tendencies according to the genetic information of embryos, improve the success rate of IVF and reduce the risk of birth defects. For example, PGS (early blastocyst genetic screening) can screen embryo chromosome abnormalities, and PGD (early blastocyst genetic diagnosis) can diagnose single gene diseases.
In addition, emerging gene editing technologies such as CRISPR-Cas9 can also conduct embryonic gene editing at the early stage of IVF to correct some potential genetic diseases or increase the expression of some beneficial genes. The development of these embryo selection technologies will further improve the success rate of IVF and reduce the genetic transmission of diseases.
However, embryo selection technology has aroused ethical and moral disputes, because it involves human genetic transformation. Therefore, the global regulations on embryo selection technology will have an important impact on its development direction.
2. Innovative assisted reproductive technology
In addition to the traditional in vitro fertilization (IVF) technology, many innovative assisted reproductive technologies have emerged in the field of IVF. These include the following:
2.1 ICSI (single sperm injection) technology: ICSI technology solves the problem of sperm quality of male infertility patients and improves the pregnancy rate by directly injecting single sperm into eggs.
2.2 IMSI (microscopic sperm examination) technology: IMSI technology uses a high magnification microscope to observe the morphology and structure of sperm, and selects sperm with normal morphology for injection, further improving the pregnancy rate.
2.3 ERA (Window Activation of Endometrium Acceptance) technology: ERA technology can accurately determine the implantation time of high-quality embryos and improve the implantation rate of embryos by studying the time window suitable for implantation of female endometrium.
2.4 Natural circulation test tube baby technology: natural circulation test tube baby technology does not use hormone drugs, maintains women's natural menstrual cycle and ovulation, reduces the intervention on women's bodies, and can avoid the side effects of hormone drugs.
3. Combination of IVF with other technologies
IVF technology is making new breakthroughs in combination with other reproductive technologies. A new study shows that the combination of IVF technology and gene editing technology CRISPR-Cas9 can improve the transmission of genetic diseases by repairing genetic defects.
In addition, the combination of IVF technology and egg freezing technology enables women to freeze eggs at an appropriate time, and then carry out IVF process, which improves women's reproductive flexibility.
The combination of IVF technology and artificial intelligence is also being explored. By using big data analysis and machine learning algorithms, we can predict the probability of embryo development and implantation, thus improving the success rate of IVF.
4. Medical quality and international cooperation
The development of IVF technology is inseparable from the improvement of medical quality and international cooperation. Active international exchanges and cooperation can promote technological innovation and experience sharing, and improve the technology level of IVF in the world.
Many hospitals and experts at home and abroad have conducted extensive research in the field of IVF. For example, the American IVF Center in the United States, the Bloomsbury Clinic in the United Kingdom and Peking Union Medical College Hospital in China are all institutions that have made significant progress in clinical practice and scientific research.
Summary
The development trend and new progress of IVF technology mainly include the application of embryo selection technology, the emergence of innovative assisted reproductive technology, the combination of IVF with other technologies, and the promotion of medical quality and international cooperation. With the continuous progress of science and technology, IVF technology will further improve the success rate, reduce the genetic risk of disease, and bring more hope to couples who cannot conceive naturally.
