After the popularization of test tube technology, many people have successfully given birth to babies through this assisted reproductive technology, and some lucky families have given birth to twin babies through test tubes, and their families do not have twin genes, that is to say, it is possible to achieve twins through test tube technology. Therefore, many IVF families are eager to give birth to twin babies through IVF technology to achieve the purpose of one birth. So today, Hengjian Overseas will tell you that the test tube twins will succeed?
Let's first look at the success rate of ivy tube twins, according to the survey, the current ivy tube transfer routine will transfer 1-2 embryos, regardless of single or twin, the overall success rate is about 20%-30%, of which the probability of two embryos surviving twins can reach about 15%-20% on this basis. This data does not look high, in fact, corresponding to the reality, about two of the ten people who transplanted double embryos can conceive twins, which is already relatively good for families born without twin genes.
It will be more difficult to conceive twins than singletons, both before and after pregnancy. The implantation rate after the first and second generations of IVF transplantation is not too high, so in order to increase the success rate, more than two embryos will often be transferred at the same time, but the probability of implantation at the same time in this case is not large; and the third generation of IVF is transplanted in the blastocyst state, plus genetic screening has been carried out, and the implantation success rate is relatively large, so in general, only one embryo will be transferred at a time, but if the IVF mother has requirements, the doctor will judge whether it is suitable for transplantation according to the physical condition of the IVF mother.
Even if both embryos are implanted, there is a chance that one will stop developing or one will be absorbed by the other, which is normal. If we can give birth to twin babies, it is natural to be happy, but it is the purpose to successfully give birth to a baby, whether it is a single or twin, as long as the mother and child are born safely, it is already the goal of completing assisted reproduction, and there is no need to force or lose if the twins are not successfully born.
So the ivy tube twins are not necessarily successful, sometimes also look at some luck, of course, if you want to conceive twins at once, you can try to exercise well before the test tube, improve your physique, and be fully prepared for the attempt, so that the success rate will be greater!
