Three generations of test tube babies in the United States: what technological improvements contribute to success?
With the progress of science and technology, IVF has become an increasingly common assisted reproductive technology. In the United States, major hospitals and professional institutions continue to improve and innovate IVF technology to improve the success rate and reduce risks. This article will discuss the technical improvement of three generations of test tube babies in the United States from many aspects.
1. Progress in IVF technology
In vitro fertilization (IVF) is one of the most critical steps in IVF. In the past, the success rate of IVF was low, but through continuous technical improvement, modern IVF technology has made a huge breakthrough.
First of all, doctors have adopted more precise technology and advanced equipment in the process of egg collection. These devices can more accurately locate the ovary, so as to collect eggs at the best time and improve the probability of pregnancy.
Secondly, the improvement of embryo culture technology has greatly improved the success rate of IVF. Now, professional hospitals adopt the method of gradual cultivation and monitoring to ensure the optimal development of embryos. This method can more accurately evaluate the quality of embryos and select the best potential embryos for transplantation.
In addition, the progress of genetics also provides support for the improvement of IVF technology. With the help of new genetic technology, doctors can screen embryos with certain genetic defects, thereby reducing the risk of chromosomal abnormalities and improving the success rate.
2. Innovation of cryopreservation technology
Cryopreservation technology plays an important role in IVF. This technique can freeze and preserve eggs or embryos for future use. In recent years, professional institutions in the United States have made a series of technical improvements to improve the effect of low-temperature preservation.
On the one hand, more advanced freezing methods, such as liquid nitrogen freezing, are used to ensure the quality and integrity of eggs or embryos during the preservation process. This method can reduce the damage to cells during freezing and improve the survival rate of preservation.
On the other hand, the time limit and storage conditions of cryopreservation technology have also been improved. Researchers found that reducing the storage temperature and prolonging the storage time can further improve the survival and success rate of eggs or embryos. Now, many hospitals can safely store eggs or embryos for many years so that patients can resume pregnancy at a future point in time.
3. Application of pregene diagnosis technology
Pregene diagnosis is to determine whether there is a genetic disease or chromosomal abnormality before embryo transfer through genetic testing. The application of this technology not only improves the success rate of IVF, but also reduces the risk of genetic diseases of patients.
In recent years, professional institutions in the United States have promoted the innovation and application of pregene diagnosis technology. Now, doctors can accurately determine whether an embryo carries a genetic disease or chromosomal abnormality through gene detection of cells. This allows them to screen healthy embryos with the best development potential before transplantation, and improve the success rate of IVF.
4. Support technology improvement
In the process of IVF, the improvement of various support technologies also played an important role in the success rate. Among them, hormone therapy is one of the most commonly used support technologies.
In recent years, advances in targeted hormone therapy have enabled doctors to more accurately adjust hormone levels in female patients. This helps to collect eggs at the best time and stimulate the ovaries to produce more eggs, improving the probability of pregnancy.
In addition, the instruments and equipment used in assisted reproductive technology have also been improved, such as more accurate test tube dishes and precise embryo transplanters. These improvements ensure the growth environment of embryos and the accuracy of transplantation, and provide an important guarantee for the success of IVF.
To sum up, professional institutions in the United States have made continuous improvement in the success rate of third-generation IVF babies by improving in vitro fertilization technology, cryopreservation technology, pregene diagnosis technology and support technology. These technological innovations have brought new hope to infertile patients who wish to have healthy babies.
