Risk of IVF multiple pregnancy
In vitro multiple pregnancy refers to the pregnancy status of twins or more fetuses obtained through assisted reproductive technology. Although multiple pregnancy may be exciting, it also brings some potential risks and challenges. This article will elaborate on the related risks of IVF multiple pregnancy in terms of embryo implantation, pregnancy complications, premature delivery and newborn health.
Embryo implantation
The primary risk of IVF multiple pregnancy is multiple embryo implantation. In the process of IVF, multiple embryos are usually transferred into the mother's uterus to improve the success rate of pregnancy. However, too much embryo implantation may increase the risk of multiple pregnancy. Multiple pregnancy has potential adverse effects on both mother and fetus.
First, multiple pregnancies increase the risk of maternal complications. Pregnant women may face higher risks of miscarriage, premature delivery, anemia, hypertension during pregnancy, gestational diabetes, etc. At the same time, multiple pregnancy will cause additional burden on the mother's heart and kidney function.
Secondly, multiple pregnancy will also cause a series of risks to the fetus. Multiple fetuses are usually born with light weight, and there is a risk of premature delivery, which may lead to various health problems, such as underdeveloped respiratory tract, heart problems, digestive system problems, etc. In addition, multiple fetuses may also have fetal malposition, insufficient blood supply, and even a relatively high risk of fetal death.
Pregnancy complications
The second risk of IVF multiple pregnancy is the increase of pregnancy complications. Compared with other types of pregnancy, multiple pregnancy is more prone to complications.
Hypertension during pregnancy is a common complication, which is also regarded as an important part of multiple pregnancy. In this case, the increased blood pressure of pregnant women may lead to serious complications, such as pre eclampsia and eclampsia.
In addition, gestational diabetes is more likely to occur in multiple pregnancies. Due to the increased demand of multiple fetuses for insulin, this may lead to gestational diabetes mellitus in pregnant women, increasing the risk of fetal malformation and the need for birth process intervention.
Multiple pregnancies also increase the risk of anemia and thrombosis, which may require additional treatment to manage.
premature delivery
Another risk of IVF multiple pregnancy is preterm delivery. Pregnant women with multiple pregnancies often give birth in the early pregnancy week.
Premature birth may cause a series of problems. Premature infants may need special care, including ventilator support and screening for congenital diseases. Preterm infants also face a higher risk of developmental delay and cognitive impairment.
In addition, premature delivery also increases the risk of neonatal death. As premature infants are more vulnerable and vulnerable to infection, they need additional monitoring and care.
Newborn health
In vitro multiple pregnancy will affect the health of newborns. Infants with multiple pregnancies are usually born with a lower weight, which makes them more prone to health problems.
Compared with single birth infants, multiple birth infants have a higher neonatal mortality rate. At the same time, they are more prone to respiratory diseases, digestive system problems, neurodevelopmental problems and infections.
Multiple births are also at increased risk of birth defects such as heart problems, arm and leg deformities.
Summary
IVF multiple pregnancy brings many risks, including multiple pregnancy risk caused by embryo implantation, increased pregnancy complications, premature delivery and newborn health problems. Multiple pregnancy will bring additional burdens and challenges to both mother and fetus. Therefore, before using IVF technology, we should fully understand the risks and difficulties associated with multiple pregnancy, and make wise decisions under the guidance of doctors.
