When we do IVF transplantation, doctors will talk about the problem of multiple births, because many small partners want to be in place in one step, give birth to two babies at once, the child can still have companions, and the children do not need to be raised one by one, one at a time.
But when doing IVF, the doctor is most afraid of the problem of multiple births, and the more pregnancies there are, the more the doctor is worried, all try to be singletons, so when the embryo quality can be transferred, we are all transferring an embryo, if the embryo quality is poor, we only consider transferring 2, and even if only one embryo is transferred, the embryo may split into two babies on its own, we are pregnant not just for pregnancy, but for a baby that can be healthy born in the hand, Therefore, in order to avoid risks, the transfer is as much as possible single embryo transfer.
The womb is like an egg, originally the space and nutrients inside are only enough for one chick, squeezing and squeezing can supply up to two, and no matter how much the eggshell will be broken, or the chick will be strangled inside. And for our TEST patients are the same, uterine blood supply and volume support singleton is just right, multiple pregnancy early pregnancy embryo may appear embryonic nutrient deficiency, stunted; the middle stage is prone to fetal stop and miscarriage; the late stage is easy to appear fetal stop, uterine rupture, etc.,
Especially for those patients with small congenital uterine volume or congenital uterine malformations, the uterine cavity volume itself is small, and the risk of having a baby itself is higher than that of normal people, and if there are twins or multiple fetuses, then the risk of pregnancy will be greatly increased.
Therefore, in order to avoid these foreseeable adverse outcomes, to ensure that the baby has a greater chance of being born healthy and holding in the hands of adults, so the multiple pregnant women will be reduced, and the child who looks more vigorous when reducing the fetus will be selected to stay and improve the survival chances of the baby in the later stage.
In summary, we should not be greedy when transplanting, otherwise it is also a troublesome problem to face the risk of fetal reduction in the later stage.
