Factors influencing immunity of test tube infants
IVF is a kind of baby developed by cultivating fertilized eggs in the laboratory and implanting them into the mother's body through assisted reproductive technology. Compared with naturally conceived infants, IVF may have some differences in immunity. This article will elaborate on the factors affecting the immunity of IVF from four aspects: genetic factors, nutrition during pregnancy, birth mode and early diet.
Genetic factor
There may be differences in genetic factors between IVF and naturally conceived infants. Because assisted reproductive technology usually involves in vitro fertilization, embryo screening and selection, IVF may come from embryos with a certain risk of genetic diseases. These genetic diseases may lead to abnormal immune system function or susceptibility to infection. Therefore, genetic factors have an important impact on the immunity of IVF.
In addition, the immune system of IVF may also be affected by the parental immune system. If parents have abnormal immune system or immune related diseases, IVF may inherit related immune problems. These genetic factors may affect the development and function of IVF immune system.
Pregnancy nutrition
Nutrition during pregnancy is one of the important factors affecting the development of fetal immunity. The mother of test tube baby may need to inject exogenous hormones to promote ovarian ovulation, which may lead to endocrine abnormalities during pregnancy, thus affecting the development of the fetal immune system. In addition, IVF mothers generally need to use ovulation promoting drugs, which may adversely affect the normal development of the fetal immune system.
In addition, the diet of IVF babies before and after birth may also have an impact on immunity. Some studies have shown that maternal intake of antioxidants, vitamin C, vitamin E and other nutrients during pregnancy may contribute to the improvement of fetal immunity. Therefore, good nutrition during pregnancy is crucial to the immune development of IVF.
Birth mode
The birth mode is also an important factor affecting the immunity of IVF. Natural childbirth can contact the mother's vaginal flora through the birth canal, which is very beneficial to the development of the newborn's immune system. However, since IVF mothers usually go through the steps of assisted reproductive technology, they may not be able to promote the normal development of the newborn's immune system through natural childbirth.
In contrast, caesarean section may have a certain negative impact on the development of the immune system of test tube babies. Research shows that babies born by caesarean section may be more prone to immune system related problems, such as allergy and asthma. Therefore, birth mode is also an important factor affecting IVF immunity.
Early diet
Early diet also has an important impact on the immune development of test tube infants. Breastfeeding is one of the best infant diets, because it is rich in antibodies and immune cells, which helps to enhance the immunity of infants. However, some special conditions of IVF, such as premature delivery, low body weight, may lead to difficulties in breastfeeding.
When breastfeeding is not possible, proper selection of the right formula can also provide the necessary nutrition to support the development of the immune system of test tube infants. However, improper early diet may lead to immunity problems of IVF. Therefore, the correct early diet is one of the important factors to ensure the immune development of IVF.
summary
In conclusion, the immunity of IVF is affected by many factors. Genetic factors, pregnancy nutrition, birth mode and early diet are all important factors that may affect the immune development of IVF. In order to ensure the normal development of IVF immune system, parents and doctors need to pay attention to these factors and take appropriate measures to promote the healthy development of IVF.
