Can this also be called "twins"?
Twins or multiples are usually born at a time of no more than half an hour, and some even differ by less than a minute.

Can ivfection give birth to twins?
First of all, doing IVF needs to meet the indications for doing IVF, in line with infertility, there are clear indications, after examination and doctor evaluation need to do IVF to carry out, obviously, "want to have twins" is not an indication for IVF.
Theoretically, IVF would increase the proportion of twins.
However, multiple births are more risky than singles, this danger exists for mothers and children, multiple mothers are more likely to develop pregnancy syndromes such as diabetes and hypertension during pregnancy, and the probability of postpartum bleeding is also very high, and it is also more likely to occur prematurely.
Therefore, when expectant mothers detect multiple pregnancies, they will generally consider reducing the fetus.
In October 2003, the former Ministry of Health of China revised and implemented the "Human Assisted Reproductive Technology Specification", which clearly stipulates that "for multiple pregnancies, it is necessary to implement fetal reduction surgery, avoid twins, and strictly prohibit the birth of three or more pregnancies".
