Operation of IVF fetal reduction
IVF reduction refers to the selective embryo transfer of multiple pregnancies in the process of assisted reproductive technology to reduce the number of embryos. The following will elaborate on embryo evaluation, operation steps, risks and common hospitals.
Embryo evaluation
Before IVF reduction, doctors will evaluate multiple embryos. The evaluation indexes include the morphology, quality and chromosome normality of the embryo. Usually, doctors will choose one or two embryos with the best quality and normal chromosomes for transplantation.
Embryo evaluation is usually accomplished by embryo biopsy or non-invasive gene testing techniques. Embryo biopsy is to take samples of embryos and then conduct chromosome analysis to determine whether the number and structure of chromosomes are normal or not. Non invasive gene testing can even screen genetic defects of different embryos in advance by analyzing the cells and DNA released in the process of embryo culture.
Embryo evaluation helps doctors determine which embryos are healthy and thus determine the number of embryos that need to be reduced.
Operation steps
IVF reduction is usually carried out in the first trimester of pregnancy. Generally speaking, fetuses can be reduced from the third week to the fifth week of embryo transfer, when the gestational sac has not yet formed an embryo. The reduction operation will be carried out under painless anesthesia.
Doctors will use a fine needle guided by ultrasound to puncture and suck out the heart or embryonic tissue of the first embryo. This puncture process is usually short, but requires doctors to have excellent technical operation ability. If more than two embryos need to be reduced, the doctor will complete the reduction of embryos in the same operation.
After the reduction, the doctor will observe to ensure the normal development of the remaining embryos and reduce the risk of potential complications.
risk
Although IVF reduction is a common assisted reproductive technology operation, there are still some risks.
First of all, there may be some complications to the mother in the process of fetal reduction, such as infection, bleeding, etc. However, under the operation and care of professional doctors, the risk of these complications is generally low.
Secondly, the reduction of embryos may affect the development of other embryos, leading to premature delivery, fetal dysplasia and other problems. However, this risk is usually small, and doctors will evaluate and monitor it according to the specific situation to minimize these risks. At the same time, newborns and mothers also have better support in dealing with these potential problems in advance.
In general, IVF reduction is a relatively safe operation, but doctors and teams still need to have professional technology and experience to ensure the success and safety of the operation.
Common hospitals
In China, some formal medical institutions provide IVF reduction services, including Peking Union Medical College Hospital and Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine. These hospitals have advanced equipment and professional medical teams, which can provide safe and reliable IVF operations for patients.
summary
IVF reduction is an assisted reproductive technology of selective embryo transfer, which has certain characteristics in embryo evaluation, operational procedures, risks and hospital selection.
Through embryo evaluation, doctors can select healthy embryos for transplantation. The operation steps include the use of ultrasound guided fine needles for puncture and embryo aspiration in the early pregnancy. Although there are certain risks, the risks are small under the operation of professional doctors. Some regular medical institutions, such as Peking Union Medical College Hospital and Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine, can provide IVF reduction services for patients.
In general, IVF reduction is a relatively safe operation, but doctors still need to have professional skills and experience to ensure the safety and success rate of the operation.
