What are the reasons for the slow development of embryos in vitro culture

summary

If fetal growth retardation in the uterus, the morbidity and mortality will be higher than the normal weight of the baby, and in the process of production is also prone to fetal distress or early discharge of the basin. So pregnant mothers should pay special attention to the development of their children

What are the reasons for the slow development of embryos in vitro culture

First, fetal growth retardation is generally related to the poor weight gain of the mother. The ideal weight gain value is 10-15kg. If the weight of the pregnant mother before delivery is 10kg heavier than that before pregnancy, the baby will have a chance to return to the shape before pregnancy. If the weight of the pregnant mother before delivery is only 5kg heavier than that before pregnancy, it means that the mother has lost 5kg during pregnancy, This will affect the growth of the fetus more or less

Second: intrauterine infection will affect the development of the fetus in the uterus. These infections will also cause fetal growth retardation, syphilis, rubella, syphilis, Toxoplasma infection, etc.

Third: after more than 20 weeks of pregnancy, fetal growth retardation is usually caused by acquired environmental impact, which is not related to the mother's own diseases. For example, cardiovascular disease, anemia and other diseases are caused by the lack of oxygen and nutrients in the fetus, resulting in fetal growth retardation and various sequelae.

matters needing attention

In the early stage of embryo growth, it is necessary to do a good job to protect the embryo tissue from external influence and infection, leading to stop development, growth retardation and even harm and invasion to the mother.
