Angel IVF: How to measure the success rate?
IVF is a kind of assisted reproductive technology, which helps infertility patients realize their reproductive dreams through in vitro fertilization and embryo transfer. However, there may be differences in the success rate of IVF among different patients. In order to measure the success rate of IVF, the medical community has introduced a series of objective measurement indicators. This article will elaborate on how to calculate the success rate of IVF from four aspects.
1. Pregnancy rate
Pregnancy rate is an important indicator to measure the success rate of IVF. Generally speaking, the pregnancy rate is expressed by the ratio of the number of patients who successfully conceive within a specific time to the total number of patients who have tried IVF. The pregnancy rate of IVF is related to many factors, including female age, the quality of eggs and sperm, the quality and quantity of embryos, etc. According to the data of the World Health Organization, the IVF pregnancy rate of young women is generally high, between 30% and 40%; With the increase of women's age, the pregnancy rate gradually declined.
However, the pregnancy rate does not fully represent the success of IVF. Because even after fertilization and implantation, abortion may still occur. Therefore, the medical community also introduced other indicators to evaluate the results of IVF.
2. Live yield
Live birth rate refers to the proportion of live babies born in the process of IVF. Compared with the pregnancy rate, the live birth rate can more truly reflect the success of IVF. The live birth rate is affected by many factors, including the quality of embryos, the timing of embryo transfer, and the adjuvant treatment received. Statistics show that the global live birth rate of IVF is about 25% to 30%, but in some top medical institutions, the live birth rate can reach more than 40%.
The improvement of living rate depends on the continuous improvement of technology and clinical experience. Some hospitals have successfully improved the live birth rate of IVF by optimizing the formula of culture medium, embryo screening technology and the preservation method of frozen embryos.
3. Multiple pregnancy rate
Multiple pregnancy is not uncommon in IVF. Multiple pregnancy not only increases the health risk of the fetus and mother, but also leads to an increase in the incidence of premature delivery, premature rupture of membranes and other complications. Therefore, the medical community takes the multiple pregnancy rate as one of the important indicators to evaluate the results of IVF.
In order to reduce the rate of multiple pregnancy, many medical institutions have changed the strategy of embryo transfer. For example, selecting single embryo transfer or developing single embryo transfer technology can significantly reduce the risk of multiple pregnancy. Through these measures, hospitals can reduce the incidence of multiple pregnancies while ensuring the success rate of IVF.
4. Cumulative success rate
The cumulative success rate refers to the proportion of successful births after multiple cycles of IVF attempts. Because IVF is not a one-time success, many patients need to try many times. The cumulative success rate can provide patients with more comprehensive information about the possibility of success after many attempts.
The calculation of cumulative success rate provides patients with a better basis for decision-making. By understanding their own illness, the cumulative success rate of the hospital and the above indicators, patients can better evaluate and choose their own IVF programs.
Summary
In conclusion, the success rate of IVF can be measured by pregnancy rate, live birth rate, multiple pregnancy rate, cumulative success rate and other indicators. These indicators can objectively reflect the final results of patients in the process of IVF. The continuous progress of medical technology and the accumulation of clinical experience will further improve the success rate of IVF and help more infertile patients realize their dream of becoming parents.
