How to judge the health of second-generation IVF?
The second generation of IVF is an infant whose embryo obtained through assisted reproductive technology is implanted into the mother's body. With the continuous development of science and technology, people pay more and more attention to the health problems of the second-generation IVF. So, how to judge the health of the second-generation IVF? The following will elaborate on genetic screening, embryo evaluation, perinatal monitoring and postnatal evaluation.
genetic screening
Genetic screening is one of the important methods to assess the potential health risks of embryos. Before embryo implantation, genetic screening technology, such as chronic disease gene detection and chromosome abnormality detection, can be used to detect and screen embryos. Through these tests, we can find possible genetic diseases and chromosomal abnormalities in embryos at an early stage, so as to select relatively healthy embryos for implantation and reduce the risk of illness at birth.
In addition, genetic screening can also detect the sex of embryos. Some gender related diseases only affect infants of specific gender, for example, muscular dystrophy only affects male infants. Through genetic screening, embryos with these gender related diseases can be avoided from being implanted into the mother.
Therefore, genetic screening is one of the important means to judge the health of the second generation IVF infants.
Embryo evaluation
Before the embryo is implanted, the doctor will evaluate the embryo. Embryo evaluation is one of the key links in judging the health of the second generation IVF. At present, the commonly used embryo evaluation techniques include morphological evaluation and chromosome evaluation.
Morphological evaluation is mainly to observe the appearance and cell division of the embryo through a microscope, and evaluate the quality and development of the embryo. Morphological evaluation can help doctors select embryos with normal appearance and good cell division law, and improve the healthy birth rate of infants.
Chromosome evaluation usually determines whether there are chromosomal abnormalities by detecting the number and structure of chromosomes in the embryo. Commonly used chromosome evaluation techniques include cross genetic hybridization and single cell comparative genomic hybridization. Chromosome abnormalities are an important cause of many genetic diseases. Chromosome assessment can prevent infant development problems caused by chromosome abnormalities.
Perinatal monitoring
Perinatal monitoring refers to the comprehensive monitoring and evaluation of mothers and infants during pregnancy, childbirth and postpartum period. Perinatal monitoring is an important means to judge the health of second-generation IVF infants.
Pregnancy monitoring includes regular prenatal examination, blood examination and B-ultrasound examination. Through these monitoring means, we can understand the pregnancy, fetal development and maternal health, and timely find and deal with potential problems.
The delivery monitoring mainly focuses on the vital indicators of the fetus, such as fetal heart rate monitoring, uterine contraction monitoring, etc. Through these monitoring means, we can find and deal with the abnormal situation in the delivery process in time to ensure the safety of the fetus.
Postpartum monitoring is mainly to assess the growth and development of infants, and pay attention to the recovery of mothers after childbirth. Postpartum monitoring can find and deal with postpartum hemorrhage, abnormal milk secretion and other problems in time to ensure the health of mothers and infants.
Postnatal evaluation
Postnatal evaluation is the final step to judge the health of the second generation IVF babies. Postnatal evaluation is mainly carried out through physical examination, vital indicators monitoring and screening examination.
Physical examination mainly includes the evaluation of height, weight, color, skin, limb mobility and other aspects to judge the development of the baby and whether there are obvious abnormalities.
Vital indicators monitoring mainly includes the monitoring of respiration, heartbeat, body temperature and other indicators to ensure the normal vital signs of infants.
Screening inspection mainly includes newborn hearing screening, metabolic disease screening, etc., to find and prevent potential genetic diseases.
Summary
How to judge the health of the second-generation IVF is not just a link. From genetic screening, embryo evaluation, perinatal monitoring to postnatal evaluation, each stage plays an important role. Through the comprehensive assessment of the above aspects, the risk of illness at birth can be minimized to ensure the health of the second generation of IVF babies.
