Disadvantages and risks of IVF
IVF technology is an assisted reproduction technology. Through artificial insemination or in vitro fertilization, the eggs and sperm of couples with low or no chance of pregnancy are combined, and then the embryos are cultured in vitro, and then the embryos are implanted into the woman's uterus. Although IVF technology has realized the birth dream for many couples, it also has some shortcomings and risks.

1. High economic costs
IVF surgery requires a series of complex and expensive medical procedures and tests, including in vitro fertilization, embryo culture, embryo freezing and implantation. These processes require the use of expensive laboratory equipment, drugs and professional doctor costs, plus many attempts and unpredictable complications, making the cost of IVF very high. For couples with poor economic conditions, they may not be able to afford such expenses.
In addition, IVF babies need to make repeated attempts to conceive successfully, which further increases the economic burden.
2. Psychological pressure and emotional fluctuation
The uncertainty and pressure during IVF may lead to psychological problems such as anxiety and depression in couples. Because of the uncertainty of the results, couples need to bear great psychological pressure before and after IVF. Every failed attempt will have a serious impact on the couple's feelings, and a successful pregnancy may make them feel complacent or lose understanding and empathy for others.
In addition, if IVF technology leads to multiple embryo implantation, couples may have to face the dilemma of selective fetal reduction, which will bring them more complex and painful emotional attitudes and decisions.
3. Physiological risks and complications
IVF technology itself has certain physiological risks to the woman's body. Ovarian hyperstimulation syndrome may be caused by the use of hormone to promote ovulation during ovum retrieval, which may lead to complications such as ovarian enlargement, pleural effusion or thrombosis. In addition, IVF egg retrieval is an invasive process, which may cause internal bleeding, infection, ovarian damage and other risks.
For embryos, there are certain risks in the process of in vitro culture and implantation. Embryos may develop abnormally or be damaged in the process of culture and implantation, which may lead to embryo implantation failure or the birth of deformed babies.
4. Moral and ethical issues
IVF technology has caused a series of moral and ethical problems. First of all, the production, selection and implantation of embryos involve the treatment and selection of life, which has caused disputes about the origin of life and moral and ethical principles.
Secondly, IVF technology may lead to multiple pregnancies. The birth rate of multiple pregnancies and the prenatal mortality rate of infants are high, which increases the health risks of children and mothers.
summary
To sum up, although IVF technology has helped many couples realize their reproductive dreams, it is also accompanied by high economic costs, psychological pressure, physical risks and ethical issues. Therefore, before using IVF technology, couples should fully understand its shortcomings and risks and make rational decisions.
