Common problems of IVF
IVF refers to an infant who cultivates a fertilized egg in the laboratory and transfers it to the mother for pregnancy through assisted reproductive technology. Although IVF technology has made significant progress in solving the problem of infertility, there are still some common problems. The following will elaborate on the common problems of IVF from four aspects: genetic diseases, multiple pregnancy, premature delivery and low birth weight.
Hereditary disease
Like naturally conceived babies, IVF may suffer from some genetic diseases. This is because the fertilized eggs of IVF come from the genetic material of their parents, and the genetic disease genes they carry may also be passed on to the next generation. Some common genetic diseases include congenital heart disease, hereditary deafness, hereditary vision problems, etc. In order to reduce the occurrence of genetic diseases, doctors usually carry out genetic counseling and genetic testing to select healthy embryos for transplantation.
Genetic diseases may also lead to the loss or abortion of embryos during transfer. A study shows that genetic testing before transplantation is very important to reduce the abortion rate, because many embryos carry potential chromosomal defects and may not develop successfully.
Although genetic diseases are a common problem in IVF, genetic counseling and testing can reduce the occurrence of genetic diseases and improve the health rate of IVF.
Multiple pregnancy
In a single transfer, IVF may result in multiple embryo implantation, which may lead to multiple pregnancies. Multiple pregnancy brings some health risks to both mother and fetus.
For mothers, multiple pregnancy increases the risk of complications during pregnancy, such as hypertension, diabetes, premature delivery, etc. Multiple pregnancy may also lead to complications such as endometriosis and placental abruption.
For fetus, multiple pregnancy will increase the risk of premature delivery and low birth weight, which are related to the health and development of infants. In addition, multiple pregnancy may also lead to twin syndrome and other diseases.
In order to reduce the risk of multiple pregnancy, doctors usually choose to control the number of embryos when transferring embryos, or take measures after transfer to reduce the probability of multiple pregnancy.
premature delivery
The preterm birth rate of IVF was significantly higher than that of naturally conceived infants. Premature delivery refers to the delivery of a pregnant woman before 37 weeks of pregnancy. Premature birth may lead to incomplete development at birth, requiring additional care and monitoring.
The causes of premature delivery include multiple pregnancy, cervical weakness, pregnancy complications, etc. In vitro babies, the probability of multiple pregnancies is high, thus increasing the risk of premature delivery. In addition, IVF mothers need to receive a series of hormone therapy and assisted reproductive technology during pregnancy, which may also affect fetal development and increase the possibility of premature delivery.
In order to reduce the risk of premature delivery, pregnant women need regular prenatal examination and prenatal care. Doctors will take measures in advance according to the situation of pregnant women to ensure the healthy development of the fetus.
low birth weight
IVF babies are usually born at a lower weight than naturally conceived babies. Low birth weight means that the weight at birth is less than 2500 grams. Low birth weight can lead to health problems such as dyspnea, infection and malnutrition.
The low birth weight of IVF is mainly caused by premature delivery and multiple pregnancy. Premature birth and multiple pregnancies increase the risk of infant stunting, leading to low birth weight.
In order to increase the birth weight of test tube babies, doctors usually advise pregnant women to maintain a good nutritional status during pregnancy, and at the same time, they should carry out regular prenatal examinations and carry out necessary treatment according to the development of the fetus.
summary
The common problems of IVF mainly include genetic diseases, multiple pregnancy, premature delivery and low birth weight. Genetic diseases may affect the development of embryos and the success rate of transplantation, while multiple pregnancy increases the health risks of mothers and fetuses. Premature birth and low birth weight may cause health problems in infants. In order to reduce the occurrence of these problems, doctors will conduct genetic counseling and testing, control the number of embryos, and provide prenatal care and treatment. Through these measures, the health rate of IVF can be improved.
