With the development of reproductive assistive technologies, more and more families with infertility symptoms have realized their dreams of having children by choosing IVF technology. Twins, which used to be rare, are now common in the surrounding areas of life. Is it the twins' chances of becoming pregnant, or is it that reproductive assistive technology has helped them improve?
The chances of conceiving twins naturally are very small, about 1%-1.5%. In the case of IVF, in order to ensure the probability of IVF pregnancy, it is generally necessary to transfer 1 to 2 embryos into the woman's womb, if the two embryos survive at the same time, it is a twin, so the probability of having twins in IVF is higher than that of natural pregnancy. However, IVF does not guarantee the birth of twins, because the number of transferred embryos generally can not be too much, the mainland stipulates that the first time under 35 years of age to do IVF, only two embryos can be placed; under 35 years old for the second time or over 35 years old can be placed for the first time. In addition, not all of the embryos can survive after placement, which is determined by natural selection, sometimes placing two or three embryos can all survive, but it is also possible to all abort or only one, a process that the doctor cannot guarantee.
Although the twin rate of the test tube is relatively high, it can make pregnant mothers conceive twin babies, and some pregnant couples will think that since the probability of doing the test tube to get twins is large, they want to fight. If it's twins, if it's a dragon and phoenix fetus, it's really a good word to be a pair! Is IVF technology feasible for twins?
First of all, IVF is to help couples who cannot conceive naturally to achieve the dream of childbearing, there are clear indications, usually young women of childbearing age need to be contraceptive and not pregnant for more than 1 year, after examination, they need to do IVF treatment before they are carried out, and giving birth to twins is obviously not an indication for IVF.
Secondly, twin pregnancy will cause an increase in the incidence of many pregnancy complications, such as hypertension during pregnancy, diabetes, late miscarriage, premature rupture of membranes, etc., which will significantly increase the caesarean section rate, and may even cause postpartum hemorrhage, endangering the safety of maternal life. For newborns, twin pregnancies tend to cause low birth weight and increase the rate of birth defects in newborns.
Giving birth to twins is not only a problem of chance, but also accompanied by potential risks, therefore, pregnant couples do not blindly pursue twin babies, mothers and babies are safe and healthy, in order to be happy and happy!
