Is it easy for twins to have high success rate of IVF?
IVF technology has made a great breakthrough in solving the fertility problem, and has become an effective means for many infertile couples to achieve their fertility aspirations. However, many people are concerned about whether IVF will increase the probability of twins? This article will elaborate on this issue from many aspects.
1. Superovulation technology may lead to multiple pregnancy
One of the key technologies of IVF is superovulation technology, which increases the chance of pregnancy by promoting the development and ovulation of eggs. However, superovulation may also lead to multiple pregnancies. In the process of superovulation, multiple eggs may develop and be discharged at the same time. If all eggs are successfully implanted after fertilization, it will lead to the pregnancy of twins or multiple fetuses.
However, with the progress of technology, doctors can reduce the risk of multiple pregnancy by adjusting the dosage and method of ovulation promoters and monitoring the ovulation cycle. For example, doctors can reasonably master the use of ovulation promoters according to women's age, physical condition, infertility reasons and other factors, so as to reduce the number of eggs, thereby reducing the probability of multiple pregnancies.
2. Embryo segmentation may lead to twins
In the process of IVF, doctors usually cultivate multiple embryos in the laboratory, and then select the best one or several embryos for transplantation. However, sometimes in order to improve the success rate, doctors may choose to split an embryo into two and transplant them separately. This technique, called embryo segmentation, can increase the chances of twins.
However, it should be noted that embryo segmentation is not a conventional practice and will only be used in specific circumstances. The split embryo can be mainly used in the following two situations: first, if both husband and wife have serious infertility problems, only one embryo has a low success rate for transfer, the split embryo can increase the success rate; Secondly, if both husband and wife are worried about the failure of IVF transplantation, embryo segmentation can increase the success rate.
3. Twins may increase the success rate
Although the success rate of IVF is high, not all transplants will succeed. Some studies have shown that the success rate of multiple pregnancy (including twins) is relatively high. This is because in twin pregnancy, if the development of one embryo is blocked, the other embryo may still continue to develop and successfully conceive. Therefore, some doctors and couples choose multiple pregnancies to increase the success rate of IVF.
However, multiple pregnancy also brings a series of health risks, including premature delivery, low weight, birth defects, etc. Therefore, doctors will generally decide whether to transfer multiple embryos according to the specific situation of the couple and the risk and success rate of multiple pregnancy.
4. Summary
The high success rate of IVF does not mean easy twins. Although IVF technology may increase the probability of twins, doctors can reduce the risk of multiple pregnancies by adjusting the use of superovulation technology and embryo segmentation technology. At the same time, although multiple pregnancy may increase the success rate, it will also bring a series of health risks. Therefore, the final decision should be the result of consultation between doctors and couples.
In a word, the development of IVF technology has brought hope to infertile couples, but when choosing to transfer embryos, we must consider the success rate and health risks and other factors comprehensively to make the most appropriate decision.
