Is there a high probability of multiple births in IVF?
The emergence of IVF technology has brought good news to many infertile patients. However, compared with natural pregnancy, IVF has a higher probability of multiple births. The following is a detailed description of the reasons for the high probability of multiple births in IVF from four aspects.
1. Multiple embryo transfer increases the probability of multiple births
One of the key steps of IVF technology is embryo transfer. In order to improve the success rate of pregnancy, multiple embryos are usually transferred into the uterus. This increases the possibility of multiple births. According to statistical data, in the pregnancy cycle, the success rate of single embryo transfer is about 30%, while the success rate of double embryo transfer is about 40%. Therefore, in order to improve the success rate, many patients will choose multiple embryo transfer, thereby increasing the probability of multiple births.
However, it should be noted that multiple embryo transfer increases the probability of multiple births and also increases the risk of pregnancy complications. Multiple pregnancy is easy to cause premature delivery, low weight, hypertension during pregnancy and other problems, which brings risks to the health of mothers and infants. Therefore, when conducting IVF treatment, doctors will weigh the advantages and disadvantages of multiple embryo transfer according to the patient's situation and risk assessment.
2. Relationship between age and the probability of multiple births
In addition to multiple embryo transfer, the age of the patient is also one of the important factors that affect the probability of multiple births of IVF. Research shows that the older a woman is, the higher the probability of multiple births. This is because the aging will lead to the decline of egg quality, and the poor development of embryos in the culture process. Therefore, more embryos need to be transferred to improve the pregnancy success rate.
In addition, older women often face more infertility problems, which also forces them to choose multiple embryo transfers to increase their chances of pregnancy. Therefore, the probability of IVF multiple births is higher among middle-aged women and older women.
3. High quality embryos increase the probability of multiple births
The embryo culture stage of IVF treatment is another factor that affects the probability of multiple births. Patients with high-quality embryos usually have more high-quality embryos available for transfer, thus increasing the possibility of multiple births.
However, it should be noted that although patients with high-quality embryos may be more likely to conceive multiple pregnancies, this also means that they may face a higher risk of multiple pregnancies. Therefore, when selecting embryos, doctors will comprehensively consider the quality of embryos and the situation of patients to ensure a good pregnancy success rate and pregnancy outcome.
4. The multiple births rate of test tube babies is related to the hospital policy
Finally, the probability of IVF multiple births is also related to the policies and operation methods of different hospitals. Some hospitals may have restrictions on multiple embryo transfer, such as only single embryo transfer, to avoid the risk of multiple pregnancy. Other hospitals may be more active in promoting double embryo or multiple embryo transfer to improve the success rate of pregnancy.
To sum up, the high probability of IVF multiple births is due to multiple factors such as multiple embryo transfer, aging, good embryo quality and hospital policies. Although the birth rate of multiple births is high, the risks of multiple pregnancies should also be considered. Therefore, when conducting IVF treatment, doctors will make the most suitable treatment plan according to the patient's conditions, so as to achieve the best pregnancy and pregnancy results.
