What are the adverse effects of IVF on the body
IVF is an infant who transfers embryos to the mother after in vitro fertilization through assisted reproductive technology. Although IVF technology helps couples who cannot conceive naturally realize their reproductive dreams, people have long debated what adverse effects IVF will bring. The following will elaborate on four aspects: (1) premature birth and low birth weight, (2) risk of genetic diseases, (3) mental health and social problems, and (4) growth and development problems.
1. Preterm birth and low birth weight
The main risks of IVF pregnancy are premature delivery and low birth weight. Since the embryo transfer of test tube baby occurs in vitro, not through natural pregnancy process, its pregnancy period is shorter than that of natural pregnancy, and the time for normal growth and development is compressed, leading to an increased risk of premature delivery. In addition, IVF babies may also be restricted in nutrition and oxygen supply, leading to low birth weight. Premature birth and low birth weight have adverse effects on the health and viability of infants.
In addition, the study also found that IVF pregnancy by implanting multiple embryos may increase the risk of premature delivery and low birth weight. Although multiple embryo pregnancy can increase the probability of successful pregnancy of IVF, it also increases the risk of premature delivery and low birth weight.
2. Risk of genetic disease
IVF may face the problem of genetic disease risk. In IVF technology, the genetic information of embryos comes from the spouses of both parties, which is different from the random combination of natural pregnancy, so the risk of genetic diseases is relatively high. Although in IVF technology, healthy embryos can be screened by means of gene screening and embryonic genetic diagnosis, the risk of genetic diseases cannot be completely excluded.
In addition, some genetic diseases may not show up until the baby is born, which also brings further risks and adverse effects to IVF.
However, with the continuous progress of genetics and gene diagnosis technology, the risk of IVF suffering from genetic diseases has been greatly reduced, but it still needs to be vigilant and guarded against.
3. Mental health and social problems
IVF babies may face mental health and social problems. With the change of fertility mode, IVF may face some psychological problems. Because IVF babies usually need to go through many medical examinations and treatment processes, they may feel different, thus leading to mental health problems.
In addition, IVF may also face social problems. Some people who do not know about IVF technology may have prejudice and discrimination against IVF, resulting in IVF difficulties in social and communication. This may affect the social adaptability and emotional health of IVF.
4. Growth and development problems
IVF babies may have problems with growth and development. Research shows that the growth rate and physical development of IVF may be affected during pregnancy, after birth and childhood. Compared with naturally pregnant children, IVF may face a higher risk of growth retardation and short stature.
In addition, IVF may also face problems in cognitive and intellectual development. Some studies have found that IVF infants scored lower in intelligence tests, which may be related to factors such as premature delivery, low birth weight, genetic diseases and psychological stress.
Summary
Although IVF technology has brought hope for couples who cannot conceive naturally, IVF also has some adverse effects. First, preterm birth and low birth weight are the main risks of IVF pregnancy, which have adverse effects on the health and viability of infants. Secondly, IVF may face the risk of genetic diseases. Although the screening technology has been improved, we still need to be alert. In addition, IVF babies may face mental health and social problems, as well as growth and development problems. Therefore, when carrying out IVF technology, it is necessary to balance the advantages and disadvantages, strengthen medical management and psychological support, so as to reduce the occurrence of adverse effects.
