Why does a test tube still cause baby deformities? What are the causes of malformed test tubes? Due to the development and growth of in vitro fertilization (IVF), an increasing number of infertility patients choose to directly use IVF to give birth to their babies. The controversy faced by in vitro fertilization, such as some negative news that babies born using in vitro fertilization technology have a higher incidence of deformities than those born under normal fertility. So why do test tubes still have baby deformities? What are the causes of malformed test tubes?

Poor medication during early pregnancy

The most sensitive period for the teratogenic effect of drugs on fetuses and babies is within 3 months of pregnancy. If drugs interfere with the process of organ cell generation and differentiation, it can cause organ malformations in fetuses and babies. Using one drug at a time can cause multiple organ deformities, and it is also highly possible that multiple drugs can cause a single deformity together.

Malformed fetus caused by viral infection

The incidence rate of viral infection during pregnancy is higher than that of ordinary women, and almost most viruses can be transmitted to the fetus and baby. Rubella virus, cytomegalovirus, varicella zoster virus, etc. have a significant impact on the fetus and baby.

Harmful gases cause malformed fetuses

If a pregnant mother is exposed to harmful gases for a long time during pregnancy, the fetus and baby will also be affected by these harmful pollutants during the development stage, resulting in cell division, changes in tissues and organs, and chromosomal mutations are the key causes of infant deformities.

Poor lifestyle and behavioral habits

Some mothers love beauty very much, and even after pregnancy, they still cannot change their makeup habits. According to a survey, the incidence rate of deformed fetuses among people who wear heavy makeup every day is 1.25 times that of those who do not wear heavy makeup. The main adverse effects on the development of malformed fetuses are toxic substances such as arsenic, lead, and mercury contained in makeup products. After these components are absorbed by the skin and mucous membranes of pregnant women, they can pass through the blood fetal barrier and enter the blood circulation of fetuses, affecting the normal development of fetuses.

Why do test tubes still cause baby deformities? What are the causes of malformed test tubes? Overall, whether it is a natural pregnancy or in vitro fertilization, the probability of deformities is basically the same. Therefore, in order to avoid deformities, it is important to pay attention to them in daily life.
