What is the success rate of second-generation IVF?
With the continuous development of science and technology, second-generation IVF technology has become a common way of assisted reproduction. So, what is the success rate of second-generation IVF? This article will elaborate from four aspects: women's age, embryo quality, auxiliary technology and hospital experience.
Age of women
Women's age is one of the important factors affecting the success rate of the second generation IVF. Generally speaking, young women are more likely to succeed in pregnancy, while older women may face greater difficulties. According to the data of the American Test Tube Baby Association, the success rate of women under 35 years old is about 50%, while the success rate of women over 35 years old is significantly lower than 30%.
The influence of age on the success rate of IVF is mainly because the number and quality of female eggs will gradually decline with the increase of age. This means that the fertilization ability of older women's eggs will be relatively weak and the success rate will be low. Therefore, for older women, more attempts and auxiliary measures may be needed to successfully conceive.
Embryo quality
Embryo quality is another important factor affecting the success rate of second generation IVF. In the process of IVF, doctors will cultivate multiple embryos in vitro and select the best quality embryos for transplantation. Whether the embryo quality is good or not is directly related to the success rate of pregnancy.
The evaluation of embryo quality mainly includes the cell division, morphological structure and chromosome number of the embryo. Generally speaking, embryos with normal cell division, complete morphology and structure, and normal chromosomes are more likely to succeed in pregnancy. Therefore, in the process of IVF, doctors will select the embryos most likely to develop into healthy fetuses for transplantation according to the embryo quality.
Auxiliary technology
The modern second-generation IVF technology involves a variety of auxiliary technologies, and the application of these technologies will also affect the success rate. The most commonly used auxiliary technologies include in vitro fertilization (IVF) and preimplantation genetic diagnosis (PGD).
In vitro fertilization (IVF) refers to the combination of female eggs and male sperm in the laboratory, the culture of embryos and then the transfer of embryos to the female uterus. IVF technology can improve the success rate of IVF, especially for couples with male infertility. In addition, PGD technology can carry out gene detection on embryos and screen embryos carrying genetic disease risk, thus improving the success rate of embryo transfer.
Hospital experience
Hospital experience is also one of the key factors affecting the success rate of second-generation IVF. Different hospitals have differences in equipment, technical level and team experience. Therefore, it is very important to choose a regular hospital with rich experience and complete equipment for second-generation IVF surgery.
For example, the IVF Center of Peking Union Medical College Hospital is one of the most authoritative IVF hospitals in China, with advanced equipment and professional team. In such a hospital, the second-generation IVF surgery can achieve higher success rate and better medical services.
summary
To sum up, the success rate of second-generation IVF is affected by many factors, including women's age, embryo quality, assistive technology and hospital experience. The success rate of young women and patients with good embryo quality is higher, and the use of IVF and other auxiliary technologies and the selection of hospitals with rich experience can also improve the success rate. Therefore, selecting the right time and hospital and combining personal conditions to carry out the second-generation IVF surgery can improve the success rate and achieve the birth of healthy babies.
