Medicine is a process of continuous progress, and it has been clinically found that neural tube malformations in fetuses with spina bifida are caused by a lack of folic acid. Therefore, it is advisable to take folic acid tablets in the early stages of pregnancy, mainly to prevent fetal neural tube malformations. The likelihood of fetal neural tube malformation increases without folic acid, and relatively decreases after taking it. So from the perspective of eugenics, it is important to take folic acid tablets throughout the first trimester of pregnancy in order to prevent fetal malformations. So when something good is found, it is better to give it for adoption so that it is a responsible attitude towards the fetus. It is also good for the normal growth and development of the fetus, so it is advisable to take folic acid tablets.
