Medical experts in the success rate of elderly IVF infants
The emergence of IVF technology has brought hope to many infertile couples, especially those who are older. However, because the aging of women will lead to the decline of ovarian function, the success rate of IVF in older pregnant women is often low. In order to solve this problem, many hospitals and experts have continuously improved the success rate of elderly IVF through research and practice.
Evaluation and screening of embryo quality
The ovarian function of elderly women declines, leading to a decline in egg quality, and the resulting embryos may be defective. Therefore, an important factor is to improve the success rate by evaluating and screening embryo quality. Through experienced doctors and advanced embryo culture system, the hospital can comprehensively and accurately evaluate embryos. One or more embryos with the best quality were screened according to the morphology, cell division and other indicators of the embryo, which improved the success rate.
In addition, some hospitals also use gene detection technology to screen embryos without chromosomal abnormalities by detecting the number and structure of chromosomes in embryos, which further improves the success rate. Through these advanced evaluation and screening methods, we can select the embryos with the most potential for survival and development, which greatly improves the success rate of elderly IVF.
Accurate control of hormone therapy
During IVF, doctors will give female patients hormone to promote ovarian development and ovulation. For elderly women, precise control of hormone therapy is particularly important. On the one hand, excessive hormone levels may lead to adverse reactions such as ovarian hyperstimulation syndrome; On the other hand, too low hormone levels may lead to poor follicular development. Therefore, through scientific and accurate monitoring and regulation, the hospital ensured that the hormone level was within the appropriate range and improved the success rate of IVF.
Advanced embryo transfer technology
Embryo transfer is a key step in the process of IVF. It is particularly important to select the appropriate transplantation time and method for the elderly IVF infants. Some hospitals have adopted frozen embryo transfer technology, that is, to freeze the high-quality embryos obtained and transfer them when the intrauterine environment is more suitable, which improves the chances of embryo implantation.
In addition, some hospitals have also developed new embryo transfer technologies, such as embryo incubator and embryo attachment technology. The embryo incubator can simulate the temperature and humidity of the environment in the uterus and provide a better environment for embryo growth; Embryo attachment technology can strengthen the adhesion between embryos and endometrium, and improve the implantation rate of embryos. These advanced embryo transfer technologies provide better choices for elderly patients and improve the success rate of IVF.
Summary
To sum up, modern medical technology has made significant progress in improving the success rate of elderly IVF infants through efforts in evaluating and screening embryo quality, precise control of hormone therapy, and advanced embryo transfer technology. Although the success rate of elderly patients is relatively low, with the continuous development of science and technology and the accumulation of medical experts' experience, it is believed that there will be more methods and technologies to further improve the success rate of elderly IVF in the future.
