How to determine whether IVF babies are twins?
IVF is produced through assisted reproductive technology, and its pregnancy process is different from natural pregnancy. Therefore, people sometimes wonder whether IVF is a twin. Although it is impossible to determine whether IVF is a twin by appearance and behavior, based on the methods and characteristics of IVF, we can judge whether IVF is a twin from the following aspects.
1. Check the number and development of embryos
By checking the number and development of IVF embryos, we can preliminarily determine whether they are twins. In the process of IVF assisted reproduction, multiple fertilized eggs are usually cultured, and the healthiest one or several are selected and transplanted into the mother. Therefore, if several embryos are selected during the transfer process, they may be twins. After about two weeks of pregnancy examination, doctors can further confirm the number and development of embryos.
In addition, the number and development of embryos in the uterus can be observed by ultrasonic examination. At about 6 weeks of pregnancy, ultrasound can show the heartbeat of each embryo and determine whether it is a twin.
In conclusion, checking the number and development of embryos is one of the important methods to determine whether IVF is a twin.
2. Carry out gene testing in advance
Twins often have similar genes, so genetic testing can help determine whether test tube babies are twins. Before embryo transfer of test tube baby, some cells can be extracted for gene detection. By comparing these gene information, we can determine whether the embryo is a twin.
However, gene testing has certain complexity and cost. Therefore, for test tube infants who are not sure whether they are twins, the decision to carry out gene testing needs to be made under the guidance of doctors.
3. Analysis of embryo quality
There is a certain correlation between the embryo quality of IVF and whether it is a twin. In general, the higher the embryo quality of IVF, the higher its success rate will be. If the embryo quality of IVF is high, it may indicate the presence of twins.
The embryo quality is mainly determined by morphological evaluation, including the normal shape of embryonic cells, the number of cells and cell division. By examining the cell division and the overall shape of the embryo, doctors can determine whether they are twins.
4. Discuss communication with doctors
When judging whether IVF babies are twins, it is very important to fully communicate with doctors. Doctors can comprehensively understand whether multiple embryo transplants, embryo development, gene testing and other information have been selected in the assisted reproduction process according to the specific situation of the patient, so as to make the final judgment.
In addition, doctors can also conduct quantitative analysis on the number and development of IVF embryos through professional ultrasound inspection and other tools, so as to finally confirm whether IVF is a twin.
Summary
Through the above judgment methods, we can preliminarily understand whether IVF is a twin. These methods include checking the number and development of embryos, gene testing, analyzing the quality of embryos, and communicating with doctors. However, the final diagnosis still needs doctors to make final judgments through professional diagnostic tools and methods. Therefore, it is recommended to judge whether IVF is a twin under the guidance of a doctor, so as to obtain accurate and reliable results.
