Analysis of the status quo of the success rate of older test tube infants
IVF technology is a complex and advanced medical technology. For older women, the success rate has always been a focus of attention. The following will analyze the current situation of the success rate of elderly IVF from four aspects: treatment cycle, egg quality, embryo selection and auxiliary technology.
Treatment cycle
Older women generally need multiple treatment cycles to successfully conceive, which is due to the age related factors such as endometrial thickness and ovarian hormone secretion. For example, a study conducted by a Thai obstetrics and gynecology hospital on women over 45 years old shows that it takes an average of 3-4 cycles to successfully conceive. In addition, the prolonged treatment cycle may also increase the economic burden of patients and may lead to increased psychological pressure.
However, with the continuous progress of medical technology, some professional IVF hospitals, such as a infertility center in California, USA, have significantly improved their success rate by optimizing treatment plans and improving auxiliary technology. Their research found that in a specific treatment cycle, the success rate of older women can even be close to young women.
In addition, some hospitals introduced the third-generation IVF technology, such as the multi embryo keyboard technology of a professional infertility center in Singapore, and selected the most promising embryos for implantation in each treatment cycle, thus further improving the success rate of older IVF infants.
Egg mass
One of the core problems of elderly women is the decline of egg quality. As women over 40 years old grow older, their ovarian function gradually weakens, and their egg quality will also decrease accordingly. This directly affects the success rate of IVF.
However, some high-level infertility centers have successfully improved the egg quality of elderly women by improving the personalization and fineness of ovarian stimulation programs. In a study conducted by an infertility center in New York, the US, they insisted on prolonging the ovarian stimulation cycle by increasing the dosage and duration of drug use, making the ovary more sensitive to drug stimulation, and increasing the chances of successful pregnancy for older women.
In addition, some emerging auxiliary technologies, such as ovarian protective stimulation and oocyte freezing, also provide older women with more options. The research results of an infertility center in London, England show that older women with poor egg quality can better retain the quality of young eggs and increase the success rate by freezing their oocytes first.
Embryonic selection
Embryo selection is an important factor affecting the success rate of older IVF. After the weakening of ovarian function, elderly women may face problems such as decreased embryo implantation ability and increased abortion rate.
In the research of a test tube baby center in Tel Aviv, Israel, they used a new technology called genome screening. Through genome testing of fertilized eggs, they screened the embryos without genetic disease risk and with the best gene, thus improving the implantation ability and survival rate of embryos.
In addition, the center further improved the success rate of elderly IVF by evaluating the quality of embryos and selecting the best potential embryos for implantation.
Auxiliary technology
Auxiliary technology plays a vital role in the elderly IVF. Examples include embryo cultivation technology, embryo implantation technology, endometrial preparation technology, etc.
In the research of a hospital in Bangkok, Thailand, they used a new type of embryo cultivation technology, that is, using a circular incubator to simulate the uterine environment for embryo cultivation. By simulating the constant temperature, pH value and nutritional environment of the uterine environment, the embryo development is more stable, and the success rate has been significantly improved.
In addition, some hospitals also used advanced embryo implantation technology, such as the catheter implantation technology of an infertility center in Berlin, Germany, to improve the accuracy and success rate of embryo implantation by accurately positioning the implantation position of embryos.
summary
To sum up, the success rate of older IVF infants is affected by many factors. However, with the continuous progress of medical technology, many medical institutions have significantly improved the success rate by means of optimizing treatment plans, improving egg quality, embryo selection and auxiliary technology. In spite of this, older IVF babies still face certain challenges and risks. Therefore, it is recommended that women consider giving birth as early as possible when they are young to improve the success rate of IVF babies.
