After experiencing all the hardships of preparing for pregnancy, many parents-to-be would consider transplanting multiple embryos when doing test tubes, hoping to be pregnant with twins, so that in the future, there is no need to consider the second child, and the two children can grow with each other. Go to school together, and face things together.
Of course, twins also mean double hardships. You will have to bear additional risks from pregnancy and childbirth. Raising two "four-legged golden beasts" will not be an easy task.
Even if you think carefully and have all the psychological preparations and financial preparations for welcoming twins, you still have to understand some knowledge in IVF, because after embryo transfer, whether you can become pregnant or not, you can conceive a few, not like commodity trading. The same has a clear result. There are certain risks in any human medical treatment, and test-tube babies belong to the category with relatively large fluctuations. Let's talk about some factors that may affect your twin plan.
do IVF, will give birth to twins?
Women of normal childbearing age usually only ovulate one egg a month, and usually form an embryo after conception, so the chance of having twins in natural pregnancy is less. Many people want to get twins through IVF because of "envious/saving/family planning issues". The chance of IVF having twins is significantly higher than that of natural conception. This is because IVFs are cultured in vitro to form embryos and then transplanted into a woman's uterus. If two embryos are transplanted at a time and all survive, twins will be formed.
pregnancy rate
refers to the number of pregnant/transplanted persons during the transplant period, and the main body is the prospective parents. For example, if a doctor transplants 10 pregnant women, 6 pregnancies, the pregnancy rate during the transplant cycle is 60%. Some of these patients may have transferred one embryo, and some may have transferred two embryos. If calculated according to the number of embryos, it is the implantation rate. The
live birth rate
may be rarely heard, but in fact this is the most meaningful indicator. What is the purpose of the test tube is to deliver a healthy baby. Embryo implantation and patient pregnancy are both in the initial stage. Only when the baby is born healthy can the merits be fulfilled. Therefore, the live birth rate is the ultimate goal pursued by reproductive doctors.
After pregnancy, some patients will lose embryos due to various reasons, such as early fetal arrest, ectopic pregnancy, late miscarriage, etc. After removing this part, the person who finally successfully gave birth to a healthy baby is used as the numerator, and the number of transplantation cycles is used as the denominator. This is the live birth rate during the transplant cycle.
The live birth rate is very related to age, which is divided into the live birth rate of the first cycle. For most women younger than 40 years old, it is about 30%; there is also the cumulative live birth of multiple cycles. The calculation is a bit complicated. The cumulative pregnancy rate of 6 cycles in China is 65-70%.
and after placing 2 embryos, not all of them may survive. It is also possible that only one or all of them will be aborted. This is a natural elimination process. Doctors cannot guarantee that a few embryos can be transferred to give birth to several children. However, the physical condition of each test tube woman has different ovarian conditions, so not all people are able to have twins. Therefore, we have also summarized some related suggestions for your reference:
1. Scientific ovulation induction To avoid excessive ovarian stimulation
IVF ovulation stimulation is a controlled ovulation promotion. It is often based on women’s age, ovarian function, hormone level, and physical condition to formulate an ovulation-promoting medication plan suitable for the patient’s physical condition, while using continuous B Super follicle monitoring and hormone level determination to ensure the direction and safety of promoting excretion. During the period, the medication will be adjusted according to the body's reaction and follicular development, and to achieve scientific ovulation promotion, avoid the occurrence of excessive ovarian stimulation, and avoid adverse effects and burdens on the female body.
2. Avoid blindly pursuing the number of eggs and the pursuit of twins
. The prerequisite for IVF to give birth to twins is that on the one hand, there are two or more embryos available, and on the other hand, there is the physical condition to be able to conceive twins. If IVF wants to protect women's health and scientifically promote the discharge, the first thing is to avoid blindly pursuing the number of eggs.
Don't think that if you get more eggs, you can give birth to twins, so you must look at it objectively. If you don’t have multiple eggs available, you can consider accumulating ovulation cycles to accumulate the number of embryos. In addition, for those who cannot be pregnant with twins, don’t try blindly.Try, holding a fluke. Be aware that it is more difficult and harder to have twins than to have singles, and it will also increase the physical burden of women.
3. Transfer 2 embryos, not necessarily twins
This point is to consider the success rate of in vitro twins. We say that the final twins are good for pregnancy. The premise is that there are two embryos implanted. In order to avoid multiple pregnancy and avoid the implementation of fetal reduction surgery, it is often impossible to transfer two embryos at the time of transfer. However, if one or both of the two embryos are not implanted, it is difficult to realize the twin desire. Therefore, it is not that the transplantation will be successful, and everyone needs to have a correct understanding of the chances of IVF having twins.
here also reminds everyone that for families who want to have twins, they must do a good job of relevant physical assessment, feasibility assessment, and uterine condition assessment, and risk assessment.
Want to have twin babies at one time is something that many families are very eager for, but twins are particularly demanding for women. The test tube baby technology adopts in vitro cultivation technology, which can transplant twin babies to women who meet the standards. However, the transplantation of twins may not be successful. If the health rate of one child is low, it may also affect the development and growth of the other embryo. Therefore, for families who obsess about twins, they need to choose carefully.
will never forget, there must be repercussions, it is the people who persevere. Of course, in the process of assisted fertility, the doctor will adjust the treatment plan in a timely manner according to your previous treatment, instead of simply repeating it again and again.
However, when a baby is born, looking at the little cute sleeping next to him, all the suffering is nothing. For you who have a baby, the baby’s smile is the scenery, and every day is a holiday-like happy life. .
