In vitro a big small can be healthy to give birth to, according to the specific situation analysis, the need for dynamic monitoring of fetal development, monitoring the physical condition of the pregnant woman, if the pregnancy process is smooth and relatively stable, fetal development is good, the general dual-fetal are viable, but if there is a dual-fetal pregnancy of a number of complications need to be actively preservation of pregnancy and observation.
1. can: test tube a small one that there are two gestational sacs, if the two gestational sacs are better developed, and have a normal fetal heart, the difference between the two gestational sacs is not particularly large, the process of pregnancy is smooth, the development of the two fetuses have not seen any obvious anomalies, it is possible to be healthy and give birth to, because the normal twins will not be two of the same size, which is also a normal phenomenon.
2. can not: if the test tube a small difference is relatively large, the large gestational sac development is normal, the small development is not normal, such as no fetal heart, this situation may not be able to give birth to a healthy, but most of the cases will not affect the normal one gestational sac, you should be observed to see if there is abdominal pain, bleeding and other symptoms.
In vitro a big one and a small one, whether it can be born healthy, need to be dynamic monitoring during pregnancy, strengthen the pregnancy test, according to the specific situation to choose the appropriate treatment method, found abnormalities, should be timely consultation.
