Techniques for successful IVF pregnancy
Test tube baby technology is a technology that has attracted much attention and pursuit in the medical field today. It provides a hope for those couples who cannot conceive naturally. In order to improve the success rate of IVF, the medical community continues to explore and develop new technologies and methods. The following will introduce four aspects of IVF successful pregnancy technology, and introduce the corresponding hospitals to provide these technologies.
1. Egg retrieval technology
In IVF technology, egg retrieval is a very critical step. At present, the most commonly used egg retrieval technology is transvaginal ultrasound guided egg retrieval (OVUM) technology. This technique is guided by transvaginal ultrasound probe, enabling doctors to accurately locate and extract eggs. In China, Peking Union Medical College Hospital is one of the well-known hospitals that provide this technology.
In addition, there are also some hospitals that use the technique of abdominoperitoneal egg retrieval, that is, laparoscopy. Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine is one of the hospitals that use this technology for IVF treatment.
2. Embryo culture technology
After taking eggs, eggs need to combine with sperm to form fertilized eggs, and then conduct embryo culture. In traditional IVF technology, embryo culture is generally carried out in an in vitro incubator for 2-5 days. However, with the continuous progress of medical technology, more and more hospitals begin to use continuous culture systems, that is, fertilized eggs are placed in continuous incubators for culture. This technology is more precise in culture environment, culture medium control and other aspects, which can improve the health of embryos and pregnancy success rate. Shanghai Long March Hospital is a hospital that provides continuous training system.
3. Embryo chromosome screening technology
Chromosome abnormality is one of the important reasons for abortion and IVF failure. In order to avoid embryo transfer with chromosome abnormalities, some hospitals introduced embryo chromosome screening technology. Through genome screening and chromosome detection of fertilized eggs, healthy embryos can be screened, and the success rate and pregnancy rate of transferred embryos can be improved. The First Affiliated Hospital of Xi'an Jiaotong University is one of the hospitals providing embryo chromosome screening technology.
In addition, some hospitals use genetic diagnosis technology of single gene disease in fertilized eggs to exclude embryos at risk of genetic disease. Shanghai Fudan University Affiliated Obstetrics and Gynecology Hospital is one of the hospitals providing this technology.
4. Pre pregnancy stem cell therapy technology
In traditional IVF technology, only the development of embryos and pregnancy are concerned after the transfer of fertilized eggs. The pre pregnancy stem cell therapy technology pays more attention to the treatment and preparation before pregnancy. This technology improves the maternal environment and pregnancy success rate through stem cell transplantation and treatment. Guangzhou Changjiang Hospital is one of the hospitals providing pre pregnancy stem cell therapy technology.
summary
The technologies for successful IVF pregnancy include egg retrieval, embryo culture, embryo chromosome screening and pre pregnancy stem cell therapy. The application of these technologies has continuously improved the success rate and pregnancy rate of IVF. Whether Beijing Union Medical College Hospital, Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, Shanghai Long March Hospital, the First Affiliated Hospital of Xi'an Jiaotong University, or the Obstetrics and Gynecology Hospital affiliated to Shanghai Fudan University and Guangzhou Changjiang Hospital, these hospitals have made remarkable achievements in the field of IVF, bringing hope for life to couples who cannot conceive naturally.
