What tests should be done for IVF health?
IVF technology is an assisted reproductive technology, which helps couples who cannot conceive naturally realize their reproductive dreams through artificial insemination. In order to ensure the health of IVF, couples preparing for IVF need to carry out a series of examinations. This article will elaborate on the health examination of IVF from four aspects: pre pregnancy examination, pregnancy examination, embryo health examination and genetic disease screening.
Pre pregnancy examination
The pre pregnancy examination of IVF is an important step to ensure the success of IVF. First of all, the couple needs to carry out basic physical examination, including height, weight, blood pressure and other conventional indicators to ensure good health. Next, women need to undergo gynecological examination, including examination of uterine morphology, fallopian tube patency, ovarian function, etc. For men, semen analysis is required to assess the quantity, quality and motility of sperm.
In addition, couples need to conduct a series of blood tests to exclude genetic diseases, infectious diseases and other potential health problems. Common examination items include screening for HIV, syphilis, hepatitis B, hepatitis C and other viruses, as well as thyroid function, blood type, coagulation function and other examinations.
In addition, both husband and wife can also carry out genetic counseling and genetic vector system inspection. Through genetic counseling, couples can understand the risk of familial genetic diseases, so as to select suitable embryos before IVF. The systematic examination of genetic vectors can help couples exclude the possibility of genetic diseases of embryos before pregnancy.
Pregnancy examination
Once the IVF pregnancy is successful, pregnant women need to carry out pregnancy inspection to ensure the healthy development of the IVF. Pregnancy examination includes routine prenatal examination and special examination.
Routine prenatal examination is a series of examinations that every pregnant woman needs to carry out, including blood routine examination, urine routine examination, electrocardiogram, B-ultrasound and other items. These examinations can detect fetal abnormalities in time, prevent and deal with potential complications during pregnancy.
Special examinations are carried out according to the specific conditions of pregnant women. For example, for high-risk pregnant women such as elderly pregnant women, hypertensive pregnant women and diabetic pregnant women, more detailed examinations are needed to ensure the healthy development of the fetus. These special examinations may include amniocentesis, villus biopsy, fetal electrocardiogram and other items.
In addition, pregnancy examination also includes psychological and nutritional monitoring of pregnant women to ensure their physical and mental health. Pregnant women need regular psychological counseling to relieve stress and anxiety. At the same time, reasonable nutrition is also the key to ensure the healthy development of the fetus. Pregnant women need to follow the doctor's guidance for a comprehensive and balanced diet.
Embryo health examination
Embryo health examination is an important part of IVF technology. Through the evaluation and screening of embryos, select the healthiest embryos for transplantation, and improve the success rate of IVF.
Embryo health examination can be divided into two stages: embryo culture and embryo screening. Embryo culture is to culture the fertilized egg to the appropriate stage of embryo development to ensure that the embryo has the conditions for transfer. Embryo screening is to detect whether embryos carry chromosome abnormalities or genetic diseases through genetic technology, so as to select the healthiest embryos for transplantation.
The commonly used techniques for embryo screening include gene chip, combined with fluorescence in situ hybridization (FISH) and multiplex PCR. These technologies can conduct a comprehensive genetic examination of embryos to screen abnormal embryos and reduce the risk of genetic diseases in IVF.
Genetic disease screening
Screening for genetic diseases is an important link to ensure the health of IVF. Genetic disease screening can help couples understand their own genetic disease risks, so that they can select suitable embryos for transfer before conception.
The commonly used techniques for genetic disease screening include gene sequencing, gene chip and PCR amplification. Through the detection of the couple's genes, it can be found whether there are gene mutations of genetic diseases. If the couple carries the mutation gene, they can choose to carry out the embryonic genetic test before the test tube pregnancy of the baby to choose the embryo transfer without genetic diseases.
In addition, some hospitals also provide other special genetic disease screening programs, such as cystic fibrosis screening, birth defect screening, etc. These screening programs can help couples better understand the health status of embryos and make more informed decisions.
Summary
The health of IVF requires pre pregnancy examination, pregnancy examination, embryo health examination and genetic disease screening. Pre pregnancy examination can ensure that the couple is in good health and eliminate potential health problems. Pregnancy examination can monitor the healthy development of the fetus and prevent complications. Embryo health examination can select the healthiest embryo for transfer, and improve the success rate of IVF. Genetic disease screening can help couples avoid embryos carrying genetic disease genes, select healthy embryos for transplantation, and reduce the risk of genetic diseases.
