Does IVF increase the risk of premature delivery?
IVF, the process of transferring artificially fertilized embryos in vitro through assisted reproduction technology to the mother to develop into a baby, has been widely used in recent years. However, there is some controversy about whether IVF will increase the risk of premature delivery. This article will elaborate on this issue from many aspects.
Medical research shows
First of all, many medical studies have found that the risk of premature birth of IVF is higher than that of naturally conceived infants. A study conducted by the National Institutes of Health found that in IVF pregnancy, the risk of preterm birth is as high as 15% to 20%, while in natural pregnancy, the risk of preterm birth is about 5% to 10%. In addition, a study of nearly 50000 test tube babies also found that the preterm birth rate was significantly higher than that of naturally conceived babies.
There are many reasons for IVF premature delivery, the most important reason is multiple pregnancy. In order to improve the success rate of IVF, multiple embryos are often transferred to the mother together to increase the chance of success. However, multiple pregnancy will increase the risk of premature delivery, because the space in the uterus is limited, and multiple embryos may develop at the same time, which may lead to premature delivery. In addition, compared with natural pregnancy, IVF pregnancy is often accompanied by a series of medical processes, such as egg collection, embryo culture and transfer, which may also increase the risk of premature delivery.
Influence of premature delivery on infants
Preterm birth has an important impact on the health of infants. Premature infants often have low birth weight and immature organ development, which may lead to a series of health problems. For example, premature infants are more likely to have difficulty breathing because their lungs are not fully developed. In addition, premature infants may also face problems such as delayed development of nervous system and incomplete immune system function. Therefore, we should pay enough attention to the risk of premature birth of IVF.
Measures to reduce the risk of premature delivery
Doctors and scientists have taken a series of measures to reduce the risk of premature birth of test tube babies. First, singleton pregnancy can effectively reduce the risk of premature delivery. With the development of technology, doctors can screen out the most promising embryos before IVF transplantation, which can avoid the occurrence of multiple pregnancies.
Secondly, a nutritional supplement called flavin is also used in clinical practice to reduce the risk of premature birth of test tube babies. Studies have found that flavin supplementation can significantly reduce the incidence of preterm birth in test tube infants. Flavin is a member of vitamin B group, which plays an important role in the development of fetal nervous system.
In addition, scientists are also working on how to improve the process of IVF culture and transplantation to reduce the risk of premature delivery. They hope to find a better culture medium formula and transplant opportunity, so as to increase the survival rate of test tube babies and reduce the incidence of premature delivery.
summary
In conclusion, the risk of preterm birth of IVF is higher than that of naturally conceived infants. Multiple pregnancy is one of the main causes of IVF preterm birth, and medical intervention may also increase the risk of preterm birth. Premature birth may have an important impact on the health of infants, so it is particularly important to reduce the risk of premature birth of IVF infants. By choosing singleton pregnancy, supplementing flavin and improving the process of culture and transplantation, the occurrence of preterm birth can be effectively reduced. In the future, scientists will continue to work hard to improve the success rate of IVF and further reduce the risk of premature delivery.
