Risks in IVF
With the development of science and technology, IVF technology has become the light of hope for many couples who cannot conceive naturally. However, there are certain risks during IVF. This article will elaborate on the risks in IVF process from four aspects: IVF process, embryo transfer, drug reaction and psychological pressure.
1. Risk of IVF process
In vitro fertilization is one of the key steps in IVF. This process involves taking out female eggs and male sperm, and then fertilizing them in the laboratory. However, this process is not entirely risk-free.
First, egg collection may lead to some complications, such as ovarian hyperstimulation syndrome (OHSS) and uterine perforation. OHSS is due to the accumulation of fluid in the abdominal cavity caused by ovarian hyperstimulation, resulting in abdominal distension, dyspnea and other symptoms. Uterine perforation is caused by the puncture device penetrating the uterine wall during egg retrieval, which may require surgical repair.
Secondly, the success rate of IVF is not 100%, because the quality of eggs and sperm, fertilization ability and other factors will affect the results of fertilization. Therefore, fertilization may fail, and it is necessary to try again.
In addition, in vitro fertilization also involves the process of embryo culture and screening. Because the embryo has the risk of natural growth, it may stop developing or have chromosome abnormalities.
2. Risk of embryo transfer
Embryo transfer is one of the key steps in the process of IVF. This process involves transferring the cultured embryos back to the mother's uterus. Although this process seems simple, there are certain risks.
First of all, embryo transfer may be transferred or failed. The incorrect position of the embryo may lead to displacement, affecting the success rate of implantation and pregnancy. In addition, sometimes the embryo may not be successfully embedded into the endometrium, leading to transplant failure.
Secondly, after embryo transfer, there may be hydrops in the cystic fetal membrane cavity, commonly known as pregnancy edema. In this case, the embryo will float in the effusion, resulting in abnormal embryonic development or even stop development.
In addition, there is still a risk of abortion after embryo transfer. Even if the embryo is successfully embedded in the endometrium and develops successfully, it is still possible to have fetal termination and abnormal fetal development during pregnancy.
3. Risk of drug reaction
In the process of IVF, drugs are needed to regulate women's menstrual cycle and ovarian function, and promote follicular growth and ovulation. However, these drugs also have certain risks.
First, drugs may cause changes in hormone levels, leading to mood swings, breast hyperplasia, headache and other uncomfortable symptoms. These reactions are usually temporary, but may last for a long time for some special individuals.
Secondly, the use of drugs may also cause some serious allergic reactions. For example, ovulation promoting drugs may cause anaphylactic shock, dyspnea and other serious conditions. These discomfort symptoms may need to be dealt with in time to avoid further harm to the body.
In addition, long-term use of drugs may also lead to some chronic health problems, such as cardiovascular disease, osteoporosis, etc. Therefore, doctors need to carry out strict monitoring and management in the process of drug use.
4. Risk of psychological pressure
The process of IVF has great psychological pressure on couples. Because the success rate of embryo transfer is not high, couples need to experience many attempts to achieve success. This long wait and expectation will increase the psychological burden of couples.
In addition, loss of fetus or abortion during IVF is also a common psychological risk. This kind of loss may bring great pain and sadness to the couples, and they need professional psychological support to spend it.
In conclusion, there are risks in IVF process, embryo transfer, drug reaction and psychological stress during IVF. Couples should fully understand these risks before IVF, and have detailed consultation and discussion with doctors to make wise decisions.
