Technical and process risks of IVF
IVF is a kind of assisted reproduction technology. The fertilized eggs are cultivated to the embryonic development stage through in vitro fertilization and embryo transfer, and then the embryos are implanted into the mother's uterus, helping couples who cannot conceive naturally realize their reproductive dreams. However, there are some risks in this technology and process. These risks will be described in detail from several aspects below.
1. Risk of sperm and egg quality
The success of IVF technology is directly related to the quality of sperm and eggs. If the quality of sperm is poor, such as the number of sperm is too small or the mobility is weak, the chance of fertilization will be reduced. Similarly, if the quality of eggs is poor, such as the number of eggs is reduced or the texture is poor, the development of embryos will also be affected. In addition, some genetic diseases may also be transmitted to offspring through fertilized eggs. These problems may lead to the failure of IVF or the risk of birth defects.
In order to reduce these risks, doctors will strictly screen sperm and eggs and select the best sperm and eggs for fertilization. In addition, if the couple has a history of genetic diseases, embryonic genetic screening can be carried out to exclude embryos at risk of genetic diseases.
2. Risk of multiple pregnancy
In IVF technology, doctors usually implant multiple embryos in the uterus to improve the success rate of pregnancy. However, it also increases the risk of multiple pregnancies, that is, having twins, triplets or more. Multiple pregnancies increase the risk of premature delivery, low birth weight, and other complications.
In order to avoid the risk of multiple pregnancy, doctors will limit the number of embryos implanted according to the couple's age, birth history, egg quality and other factors. If multiple embryos develop normally, the doctor may recommend single embryo implantation to reduce the risk of multiple pregnancies.
3. Complications of in vitro fertilization and implantation
The key steps of IVF technology include in vitro fertilization and embryo implantation. These steps may cause some complications. For example, in vitro fertilization may lead to ovarian hyperstimulation syndrome (OHSS), which can cause abdominal distension, abdominal pain and dyspnea.
Complications may also occur during embryo implantation, such as bleeding, infection or uterine perforation. These complications may lead to pregnancy failure or other health problems.
In order to avoid these risks, doctors will strictly control the dosage of drugs for stimulated ovaries to reduce the risk of OHSS. In addition, in the process of embryo implantation, doctors will adopt strict operating procedures to ensure safe operation.
4. Psychological, economic pressure and social problems
IVF technology is a challenge and decision-making process for couples, so it may bring psychological pressure. Every failed attempt will bring disappointment and depression, which will have a negative impact on the couple's mental health. In addition, the cost of IVF technology is high, and economic pressure may also become a problem.
In addition, social problems may arise, such as moral considerations for IVF, paternity testing, etc.
In order to mitigate the impact of these problems, couples can actively seek psychological counseling and support to balance economic pressure and quality of life. At the same time, the society needs to strengthen the scientific popularization of IVF technology and improve the society's cognition and understanding of this technology.
In conclusion, there are risks in sperm and egg quality, multiple pregnancy, complications and psychological, economic and social problems in IVF technology and process. In order to avoid these risks, doctors will ensure the success of IVF and the health of mothers and babies by screening and selecting high-quality sperm and eggs, limiting the number of embryos, strictly controlling drug dosage, and adopting safe operation procedures. In addition, couples should also actively respond to psychological and economic pressure, and society also needs to strengthen scientific popularization to promote the healthy development of IVF technology.
