Are IVF defects common?
IVF is a method of assisted reproduction through in vitro fertilization (IVF), which has brought good news to many infertile couples. However, with the continuous development of IVF technology, people began to pay attention to whether IVF has defects. This article will analyze and discuss the defects of IVF from the aspects of genetic defects, birth defects, health problems and mental health.
Genetic defect
The genetic defect of IVF mainly comes from the abnormality of the fertilized egg or gamete itself. On the one hand, the quality of fertilized eggs may be affected during in vitro fertilization, some of which carry gene mutations or abnormalities. On the other hand, children born by couples with genetic diseases through IVF technology may also inherit diseases from their parents. These genetic defects may lead to differences in children's intelligence, physiology or development.
However, according to a study of 99 major IVF clinics in the United States, the risk of genetic defects in IVF is not high. The study shows that more than 90% of IVF babies have no obvious genetic abnormalities, and there is no significant difference compared with children who are naturally pregnant.
In addition, similar results have been verified in other international studies. For example, a study in the Netherlands also found that the risk of genetic defects in IVF is equal to that in children who are naturally pregnant. Therefore, it can be said that genetic defects of IVF are not widespread.
birth defect
In addition to genetic defects, people also pay attention to whether IVF is more likely to have birth defects. Birth defect refers to the structural abnormality or dysfunction of a baby after birth. However, studies have shown that the risk of birth defects in IVF is comparable to that in naturally conceived infants.
A follow-up survey compared the birth defect rates of IVF and naturally conceived children, and found that there was no statistically significant difference between the two. This indicates that IVF does not generally have a higher risk of birth defects.
In addition, the study also found that the risk of IVF birth defects was related to the technical level of the country and hospital. The experience and standard level of the country and hospitals in IVF technology can effectively control the risk of birth defects. Therefore, strict supervision and reasonable technical operation can reduce the risk of birth defects of IVF.
health problem
In addition to genetic and birth defects, people also pay attention to whether there are health problems in IVF. Some studies have found that IVF babies may have health problems in their infancy after birth, such as low birth weight, premature delivery, etc. These health problems are related to the processing of IVF and maternal health care during pregnancy.
However, under modern medical conditions, the health problems of IVF have been effectively controlled and managed. For example, the incidence of IVF can be significantly reduced by controlling the number of embryos, selecting high-quality embryos for implantation and providing comprehensive maternal care during pregnancy.
Therefore, in the long run, the health problems of IVF are not widespread.
mental health
Finally, the psychological health of IVF has also attracted much attention. Some people worry that IVF may face discrimination and pressure from relatives, peers or society, which may have a negative impact on mental health.
However, research shows that the mental health problems of IVF are not common. Compared with naturally conceived children, there was no significant difference in the mental health level of IVF. This shows that IVF is not at a disadvantage in terms of social adaptation and mental health.
summary
To sum up, the defects of IVF are not common. In terms of genetic defects, birth defects, health problems and mental health, studies have shown that there is no significant difference between IVF and naturally conceived children. However, the technical level and hospital standards also have a certain impact on the defect risk of IVF. Therefore, when choosing IVF technology, couples should choose hospitals with rich experience and compliant operations to reduce potential risks.
