With the popularization of third-generation in vitro fertilization (PGT) technology, some expectant parents mistakenly believe that "prenatal checkups can be eliminated if embryo screening passes." In this regard, reproductive medicine experts have made it clear that third-generation test tube technology can only reduce the risk of specific genetic diseases, and routine examinations during pregnancy are still indispensable. Scientific preparation for pregnancy requires throughout the entire pregnancy cycle.
The core role and limitations of the first and third generation test tube technology
Three-generation test-tube babies (PGT) can screen out embryos with chromosomal abnormalities (such as Down syndrome) or carrying monogenic inherited diseases through genetic testing before embryo implantation, significantly reducing the risk of related diseases.
Third-generation in vitro fertilization (PGT) utilizes genetic testing before embryo implantation to identify embryos with abnormal chromosome numbers (such as Down syndrome) or those carrying single-gene genetic disorders. This significantly reduces the risk of related diseases. However, this technology has the following limitations:
1.Inability to cover all genetic defects:PGT mainly targets problems at the chromosomal level and cannot detect single gene recessive genetic diseases (such as thalassemia) or acquired abnormalities.
2. Dynamic risks during pregnancy:The fetus may face new problems during development, such as structural malformations, abnormal placental function, etc., which need to be monitored in real time through prenatal check-ups.
2. The core value of prenatal check-ups is irreplaceable
Evenif embryos are screened through third-generation test tube technology, pregnant women still need to complete the following examinations strictly in accordance with the recommendations of their obstetricians:
1. NT examination and large row ultrasound:Examine for structural abnormalities in fetal heart, brain and other organs (11-14 weeks, 22-26 weeks of pregnancy).
2. Glucose tolerance test:Diagnosing gestational diabetes and preventing complications for both mother and baby.
3. Routine monitoring:Blood tests, urine tests, and ultrasound examinations are used to assess the health of the mother and the growth of the fetus.
:“‘’,‘’.The two complement each other and are indispensable."
3. Why do elderly pregnant women need to pay more attention to prenatal checkups?
,,.In fact, increasing age significantly increases the risks of:
1. Increased probability of pregnancy complications such as pregnancy hypertension and preeclampsia
2. Fetal growth delay and increased risk of premature birth
3. Impact of maternal underlying diseases (such as thyroid dysfunction) on pregnancy.
4. Scientific advice for expectant parents
1. Follow the doctor's advice and refuse luck: The third generation test tube is not a "comprehensive insurance", and strict completion of the prenatal inspection is a responsibility for life.
1. Follow the doctor’s instructions and avoid any tendency to rely on luck.Third-generation IVF is not a “comprehensive solution”; strictly following prenatal check-ups is the responsible approach to protecting lives.
2. Personalized adjustment options:If other diseases are present (such as diabetes or immune system issues), additional specialized tests should be conducted under the guidance of a doctor.
3. Dual management of psychological and physiological aspects:Maintain a positive mindset, eat a balanced diet and engage in regular exercise. Also, cooperate with doctors for comprehensive health management throughout the entire life cycle.
Three generations of IVF technology bring hope to infertile families, but breeding healthy babies requires science throughout the process.
