The difference between in vitro twins and natural twins
The development of In Vitro Fertilization (IVF) technology enables many couples who cannot conceive naturally to have their own children successfully. One of the more special cases is the birth of twins, namely, one male and one female. Compared with natural twins, there are some significant differences in the gestation process of test tube twins, which are mainly reflected in the following aspects:
1. Incubation method
The pregnancy of natural twins refers to the condition that twins are naturally pregnant at the same time in the mother. This is caused by women producing multiple eggs or ovulating multiple times in the same cycle. The gestation mode of test tube baby dragon and chicken fetus is realized through assisted reproductive technology. First, women are treated with ovulation induction therapy to make them ovulate multiple eggs. Then, the fertilized eggs are collected and fertilized in vitro. Finally, the fertilized eggs are implanted into the mother through embryo transfer to achieve pregnancy.
2. Pregnancy rate
The pregnancy process of test tube baby dragon and phoenix fetus utilizes ovulation induction treatment, which enables women to have higher ovulation and pregnancy opportunities. In addition, surgical procedures and the application of high-tech have also improved the pregnancy rate. The pregnancy rate of natural twins is relatively low, requiring women to exceed the probability of ovulation and pregnancy of single pregnancy.
3. Pregnancy risks
There are some special risks in the pregnancy of test tube babies. First, multiple pregnancy will increase the risk of premature delivery, low birth weight and other adverse outcomes. Secondly, multiple pregnancy has a heavy load on the mother's body, which is easy to cause pregnancy complications, such as hypertension, diabetes, etc. In contrast, the pregnancy risk of natural twins is lower, because the twin pregnancy in the natural cycle is the result of natural selection, and the twins entering the pregnancy stage generally have better health conditions.
4. Embryo quality
The embryo quality of in vitro twins is usually higher than that of natural twins. This is because in the IVF process, the quality of embryos will be strictly screened, and only high-quality embryos will be selected for implantation into the mother. However, the embryo quality of natural twins has not been screened, and there is a certain quality difference.
Summary
To sum up, there are obvious differences between test tube twins and natural twins in terms of gestation mode, pregnancy probability, pregnancy risk and embryo quality. The pregnancy process of test tube baby dragon and phoenix fetus uses assisted reproductive technology, which can improve the chance of pregnancy, but also increases the risk of premature delivery and adverse outcomes. In contrast, the pregnancy rate of natural twins is low, but the risk of pregnancy is small, and the embryo quality is relatively low. For couples, it is necessary to weigh the advantages and disadvantages when choosing the method of pregnancy, and fully communicate with doctors to make the most appropriate decision.
