Today, with the spread of assistive reproductive technology, in vitro babies have become the bridge between the dreams of countless infertility families. However, in a large number of successful cases, it is common for many couples to prefer to obtain twins, even in the case of pine babies, through in vitro infant technology. While there are expectations of “goods for good” behind this, a sober analysis of medical perspectives reminds us that test tube twins are not simply double pleasures, but are associated with even greater risks for mothers and children。
It needs to be made clear that the risks of in vitro twins are inherently rooted in the biological state of “multi-pregnancy” rather than in the in vitro technology itself. Whether natural or assisted reproduction, the challenges of multiple pregnancies for both the mother and the foetus are common and often more complex than single pregnancies。
Health challenges for the matrix
For mothers, twins mean double the pressure on the body. First, the uterus needs to carry two foetuses, which can easily lead to over-inflated uterus and increase the risk of uterine rupture, especially among women with anatomy history. In cases where the previous uterine section is less than two years apart, or is accompanied by complications such as wound healing, anaemia, endometriosis, etc., it is necessary to be extremely careful to re-pregnancy and even try three。
Second, the incidence of complications during pregnancy has increased significantly. Data show that the risk of diabetes during pregnancy is much higher for pregnant women with double pregnancy than for pregnant women with single birth. These complications not only threaten the health of the mother, but may also force the doctor to terminate her pregnancy early in order to keep the mother and the child safe. In addition, the probability of post-partum haemorrhage is higher and constitutes a serious test for post-partum recovery。
At the same time, multiple pregnancies are often accompanied by anaemia. As both fetuses compete for nutrition, the biological anaemia of pregnant women tends to be more pronounced, requiring intervention through dietary iron supplementation or medical advice。
Potential crisis in foetal development
For fetuses, multiple births mean less resources for survival. The limited uterus space and the competition for nutrition and oxygen between the two foetuses make it very easy to limit intrauterine growth (fgr). Even more serious is the risk of premature birth: the rate of premature birth in two-child pregnancies is estimated at between 25 and 45 per cent, much higher than in single births. Many newborns are underweight, or even under 3 pounds, and such low birth weights are often exposed to chronic health hazards such as respiratory distress and delayed development of the nervous system。
In addition, identical twins may face specific complications, such as the “twilight blood transfusion syndrome” (ttts), i. E., the transmission of blood from one foetus to another, leading to an imbalance in blood flow mechanics, which can cause one to die in serious cases. These risks are also present in natural conception, but are even more acute in cases where in vitro infants are artificially increasing the probability of multiple births as a result of multiple embryo transplants。
Reasonable perception: abortion and prevention are key
In the face of the high risk of multiple pregnancies, the medical community generally recommends that, in the case of in vitro infants identified as doubles or multiples after transplantation, reproductive specialists should be consulted as soon as possible to assess the need for selective abortion. This is not a denial of life, but rather to reduce the overall risk, improve the healthy survival of a single foetus and ensure the safety of the mother。
At the same time, rigorous prenatal care is an important means of preventing accidents. Regular birth tests allow early detection of high blood pressure during pregnancy and abnormal foetal growth, and allow time for timely intervention. Pregnant women should also focus on rest, avoiding overwork and reducing the incentives for premature childbirth。
It is worth noting that the web-based assertion that “the overseas test tube (e. G. Ukraine, thailand) has easy access to twins” tends to confuse technological advantages with the nature of risk. The medical risks of multiple pregnancies do not disappear due to geographic location, regardless of the country in which they are performed. Conversely, some overseas agencies may be more inclined to transplant multiple embryos in pursuit of success rates, thereby artificially increasing multiple births, which in turn increases potential risks。
In vitro baby technology is a gift for life, but “twins” should not be the blind pursuit. Scientific recognition of risks and adherence to medical advice is the most responsible attitude towards mother and child in the pursuit of family well-being. May every family embrace its own happiness on the basis of safety and health。
