Does IVF result in multiple pregnancy

As a kind of assisted reproductive technology, IVF has always been favored by the vast number of infertile couples. However, many people have doubts about whether IVF will lead to multiple pregnancy. This article will elaborate on this from the following aspects.

Background Overview

IVF refers to the technology that a group of fertilized eggs or embryos are cultured in the laboratory, and then high-quality embryos are transferred into the uterus to artificially assist in pregnancy. A multiple pregnancy is one in which a pregnant woman conceives two or more fetuses at the same time. In the traditional process of natural pregnancy, multiple pregnancy is a relatively rare phenomenon, but in the process of IVF, the probability of multiple pregnancy increases significantly.

Research on Amsterdam University Hospital in Rotterdam, Netherlands

A study by Erasmus Medical Center in Rotterdam, the Netherlands, shows that the probability of multiple pregnancy in IVF technology is high. The study tracked the data of more than 20000 IVF births and found that more than 35% of IVF births were multiple births. This is mainly because in the IVF technology, in order to improve the success rate, multiple embryos are usually transplanted into the uterus at the same time.

However, as multiple pregnancy brings certain risks to the health of mothers and infants, the University Hospital of Amsterdam in Rotterdam is also trying to reduce the probability of multiple pregnancy. They try to reduce the risk of multiple pregnancy by optimizing the method of embryo selection and transferring only the best quality embryos.

Other hospital studies

In addition to the research conducted by the University Hospital of Amsterdam in Rotterdam, the Netherlands, other hospitals have conducted similar research. A survey of multiple pregnancy in test tube babies in the UK shows that more than 25% of test tube babies are multiple pregnancy. In the United States, according to the data of the American Society of Reproductive Medicine, the multiple pregnancy rate of test tube babies is closely followed by around 30%.

Although different hospitals have obtained different data of multiple pregnancy rate through different research methods, in general, IVF technology does lead to a higher risk of multiple pregnancy.

Summary

To sum up, the risk of multiple pregnancy in IVF technology does exist. This is mainly because in order to improve the success rate, IVF usually transfers multiple embryos at the same time. However, multiple pregnancies pose a risk to the health of mothers and infants, so hospitals are trying to reduce this risk, for example, by optimizing the method of embryo selection. Although the research results of different hospitals are different, the general trend is that the probability of multiple pregnancy caused by IVF technology is higher.
