Risk of IVF success
IVF technology is an assisted reproductive technology, which combines female eggs and male sperm in the laboratory to form a fertilized egg and then transfer it to the female uterus for pregnancy. However, IVF is not without risks. The risks of IVF success will be elaborated from four aspects: embryo selection, multiple pregnancy, pregnancy complications and psychological stress.
Embryo selection risk
In the process of IVF, doctors often cultivate multiple fertilized eggs in the laboratory and select the embryo most likely to be successfully implanted for transplantation. However, embryo selection will face certain risks.
First, due to the limitations of embryo selection, the selected embryos may not be healthy, but may have genetic defects or chromosomal abnormalities, which may lead to pregnancy failure or genetic diseases after the birth of children.
Secondly, because only the embryo most likely to be implanted successfully can be selected for transplantation during the process of embryo selection, the remaining embryos may be discarded, which has caused some ethical and moral problems.
In addition, there may be problems in the process of embryo implantation, for example, the embryo may not be successfully embedded into the endometrium, leading to pregnancy failure.
Risk of multiple pregnancies
IVF technology may lead to multiple pregnancies, that is, a single transfer leads to the successful implantation of multiple embryos. Although multiple pregnancy can improve the success rate, there are also risks.
Multiple pregnancies increase the risk of maternal and fetal complications. Mothers may suffer from premature delivery, hypertension, anemia and postpartum hemorrhage. For fetuses, multiple pregnancies increase the risk of premature delivery, low birth weight and stunting.
In addition, multiple pregnancy will increase the cost of medical monitoring and medical support during pregnancy, which will also bring some pressure on the family economy.
Risk of pregnancy complications
Compared with natural pregnancy, IVF pregnancy has some special risk of complications.
First, IVF pregnancy may lead to a higher risk of miscarriage. As the IVF technology has gone through many laboratory operations and embryo transfer processes, the abortion rate during pregnancy is relatively high, and the couple's mental and physical health has brought pressure.
Secondly, IVF pregnancy also increases the risk of pregnancy complications such as gestational diabetes and pregnancy induced hypertension during pregnancy.
In addition, IVF pregnancy needs hormone replacement therapy to help embryo implantation and maintain pregnancy after embryo transfer, but this may also increase the risk of hormone related complications.
Psychological stress risk
The psychological pressure on couples during IVF treatment is enormous.
First of all, the success rate of IVF is not 100%. Couples may need to go through multiple treatments to get pregnant successfully, which will make couples face great psychological pressure and anxiety.
Secondly, couples need to go through a series of physical examination, hormone therapy, surgery and other procedures in the process of IVF, which may have a certain impact on their physical and mental health.
In addition, couples also face possible risks such as treatment failure and abortion in the process of IVF, which will have a huge impact on the couple's psychology.
Summary
The success of IVF technology is not without risks. Embryo selection risk, multiple pregnancy risk, pregnancy complications risk and psychological pressure risk are possible challenges in the process of IVF success. Therefore, before choosing IVF technology, couples should conduct a comprehensive assessment and consultation, understand and weigh these risks, and make rational decisions.
