Differences between IVF and normal infants
IVF is fertilized and cultured in the laboratory through assisted reproductive technology, and then the embryo is implanted into the mother's uterus for development. Compared with IVF, normal babies are naturally conceived and delivered. From many aspects, there are some differences between IVF and normal infants.
1. Pregnancy mode
IVF is conceived through in vitro fertilization. In the process of IVF, the female egg and the male sperm are combined in the laboratory, and then the embryo is developed in the culture dish, and finally the healthy embryo is implanted into the female uterus. In normal infants, male and female germ cells combine in the body and develop into embryos through natural pregnancy.
The mode of IVF pregnancy enables infertile couples to achieve their fertility aspirations, but it is also necessary to consider the limitations and risks of technology, such as the impact on mother and embryo and the uncertainty of success rate.
2. Physiological and psychological factors
The process of IVF may require drug intervention to promote egg production and collection, as well as embryo transfer. These interventions may have a certain impact on women's body, such as side effects of drugs, trauma and discomfort that may be caused by the operation process. The pregnancy process of normal infants is natural and does not require external intervention.
In addition to physiological factors, the process of IVF may also bring psychological pressure and challenges to couples. The failure of IVF may bring frustration and disappointment to couples, while a successful IVF may also make them happy and happy. In contrast, the process of pregnancy and delivery of normal infants is more natural, which may not have such a big impact on the psychological state of couples.
3. Pregnancy success rate
The success rate of IVF is affected by many factors, including female age, reproductive system status, embryo quality, etc. According to medical practice, the success rate of IVF is generally between 40% and 60%, providing a glimmer of hope for many infertile couples. However, some couples may need several attempts to succeed, which may lead to a longer treatment process and higher financial burden.
In contrast, the pregnancy success rate of normal infants is higher, because the natural way of pregnancy is more in line with the physiological characteristics of the body. There may still be some uncertain factors in the pregnancy process of normal infants, but the success rate is usually high.
4. Certainty and controllability
The process of IVF is carried out in the laboratory. Embryo quality and health are screened before implantation. This enables the embryo quality and genetic disease risk of IVF to be certain and controllable. For example, for couples carrying genetic disease genes, screening methods can be used to avoid passing on genetic disease risks to the next generation.
Normal infants are unable to carry out similar early screening and testing. The risk of hereditary diseases in normal infants may be judged by the family history of hereditary diseases, but it cannot be accurately screened at an early stage like IVF.
Summary
In conclusion, there are some differences between IVF and normal infants in terms of pregnancy mode, physiological and psychological factors, pregnancy success rate, certainty and controllability. The emergence of IVF has brought hope to some infertile couples, but its process and risks need careful consideration. Normal infants rely on the natural pregnancy and delivery process. Although the pregnancy success rate is high, there is no certainty and control of IVF. The choice of IVF or normal infants should be based on personal circumstances and needs.
