Can IVF put two embryos?
IVF refers to the method of placing the fertilized eggs in the uterus of pregnant women during IVF and helping infertile couples achieve fertility through assisted reproductive technology. In IVF technology, there is often a controversial issue, that is, whether two embryos can be placed. This article will elaborate on this issue from many aspects.
1. Theoretical feasibility
In theory, it is completely feasible to place two embryos. Because the success rate of IVF technology is relatively low, the implantation of two embryos into the uterus can improve the probability of successful pregnancy. However, it also brings some problems and risks.
First, implantation of two embryos may increase the risk of multiple pregnancies. Multiple pregnancies increase the risk of maternal and fetal complications, such as preterm birth and birth defects. This risk may be higher for older pregnant women or pregnant women with other health problems.
In addition, the physical burden on pregnant women during pregnancy also increases. Multiple pregnancy means that pregnant women need to bear more physiological and psychological pressure, and may need more medical monitoring and auxiliary technical support.
2. Legal and ethical issues
In some countries or regions, placing multiple embryos is explicitly prohibited. For example, the UK's Human Assisted Reproduction and Embryo Management Act stipulates that in most cases, only one embryo can be implanted in the IVF process to reduce the risk of multiple pregnancies.
The consideration behind this is to protect the health of pregnant women and fetuses and avoid possible medical and ethical problems. However, some countries or regions with relatively loose implementation also allow the implantation of two embryos, but usually have a strict application and review process.
3. Medical experience and technical level
Another factor determining whether two embryos can be placed is the experience and technical level of the medical institution. Most IVF clinics will strictly evaluate the patient's condition, including age, birth history and physical condition, to determine whether it is suitable to place two embryos.
If doctors believe that patients have a higher success rate and a lower risk of multiple pregnancies, they may recommend simultaneous implantation of two embryos. However, this decision should be made on the basis of fully informing patients, so that they can understand the potential risks and consequences.
4. Reality of double embryo implantation
In reality, not every IVF will place two embryos. This decision is usually based on the individual's situation and the doctor's judgment. Some IVF clinics prefer to place an embryo to reduce the risk of multiple pregnancies.
However, in some cases, placing two embryos can increase the chance of pregnancy. For those patients who are older, have a poor reproductive history or have failed many times, placing two embryos may be a way to try to improve the success rate.
Summary
It is possible to place two embryos for IVF. However, this decision needs to consider many factors, including potential risks and legal and ethical issues. The experience and technical level of medical institutions are also important factors in deciding whether to place two embryos. The final decision should be made on the basis of full communication and joint decisions between patients and doctors.
