How to reduce the risk of IVF multiple births

The development of IVF technology has brought hope to infertile couples. However, an important issue related to this technology is the occurrence of multiple births. Multiple pregnancy will increase the risk of pregnant women and fetuses. Therefore, reducing the risk of IVF multiple pregnancy has become the focus of the medical community. The following details how to reduce the risk of IVF multiple births from four aspects: controlling the number of embryos, selecting high-quality embryos, improving embryo transfer technology and rational drug use.

Control the number of embryos

Controlling the number of embryos is the first step to reduce the risk of multiple births in IVF. Generally, in order to improve the success rate of pregnancy, doctors often transfer multiple embryos in the IVF cycle. However, the simultaneous implantation of multiple embryos may lead to the occurrence of multiple embryos. Therefore, it is very important to control the number of embryos. At present, many hospitals have adopted the strategy of single embryo transfer, in which only one high-quality embryo is selected for transfer, so as to reduce the risk of multiple births. In addition, the application of embryo freezing technology is also an effective means to reduce the risk of multiple births. By cryopreservation of the remaining high-quality embryos, twin or multiple births caused by multiple embryo transplantation can be avoided. In the subsequent cycle, the embryos can be thawed and transferred at an appropriate time.

Select high-quality embryos

Selection of high-quality embryos is the key to reduce the risk of multiple births. Generally speaking, high-quality embryos have a high implantation rate and development potential. Therefore, selecting high-quality embryos for transplantation can reduce the incidence of multiple births. At present, some hospitals have introduced technologies based on embryo quality assessment, such as morphological assessment, chromosome screening, etc., which can help doctors select high-quality embryos and reduce the risk of multiple births.

Improve embryo transfer technology

The improvement of embryo transfer technology can also reduce the risk of multiple births. The traditional method of embryo transfer is to put embryos directly into the uterine cavity, but this method can not accurately control the number of embryos. In recent years, some advanced embryo transfer technologies have been widely used, such as embryo capsule technology and embryo hole technology. These techniques can improve the survival rate and survival rate of embryos during the transfer process, and reduce the occurrence of multiple births.

rational use

Rational drug use is also an important factor to reduce the risk of multiple births. In the process of IVF, the use of ovulation promoting drugs can increase the number of ovulatory follicles and improve the pregnancy rate. However, too much or too high concentration of ovulation promoting drugs may lead to multiple follicle maturation and a large number of oocytes fertilization, increasing the risk of multiple pregnancies. Therefore, reasonable regulation and monitoring of the dosage and concentration of ovulation promoting drugs can effectively reduce the incidence of multiple births. To sum up, to reduce the risk of IVF multiple births, we need to control the number of embryos, select high-quality embryos, improve embryo transfer technology and rational drug use. The medical community has been making continuous efforts to research and improve relevant technologies to improve the safety and reliability of IVF technology and bring better fertility results to infertile couples.
