The difference between the steps of IVF and natural pregnancy

IVF is an assisted reproductive method realized by in vitro fertilization. Compared with natural pregnancy, IVF has many differences. The differences between IVF steps and natural pregnancy will be described in detail from four aspects.

1. Pregnancy process

There are obvious differences between IVF pregnancy and natural pregnancy. IVF is the process of fertilization in the laboratory, and natural pregnancy occurs naturally in the female body. IVF is to combine male sperm with female eggs in the laboratory to form a fertilized egg, and then transfer the fertilized egg to the female uterus for implantation. In contrast, in natural pregnancy, sperm and eggs are combined and fertilized in the female body through sexual intercourse, and then implanted and grown in the female uterus. The pregnancy process of IVF requires many tedious steps, including female ovulation guidance, egg collection, sperm extraction and preparation, in vitro fertilization, embryo culture, embryo selection and transfer. These steps require multiple medical examinations and procedures to ensure embryo quality and success rate.

2. Degree of medical intervention

Compared with natural pregnancy, IVF needs more medical intervention. In natural pregnancy, women's ovulation and pregnancy process is independent and does not need external intervention. However, in the process of IVF, women need to receive hormone therapy to promote ovulation, and control ovarian function and cycle through drug regulation, so as to collect eggs at an appropriate time. These medical interventions can regulate women's physiological conditions, improve the probability of pregnancy, but also increase the burden and risk of the body.

3. Success rate and follow-up problems

The success rate of IVF is relatively low, while the success rate of natural pregnancy is relatively high. The success rate of IVF is affected by many factors, including female age, some diseases, egg and sperm quality, etc. According to statistics, the success rate of IVF is about 30% to 40%, while the success rate of natural pregnancy is usually between 15% and 20%. The success of IVF does not only mean pregnancy, but also requires embryo implantation and smooth development, as well as the final healthy birth. In addition, IVF may face some follow-up problems. For example, women may have side effects such as hormonal imbalance and ovarian hyperstimulation syndrome during IVF. In addition, after IVF embryo transfer, long-term pregnancy monitoring and special care are required.

4. Cost and time

The cost and time cost of IVF far exceed that of natural pregnancy. IVF requires multiple hospital visits, drug treatment, laboratory operations, etc., which will incur a lot of costs. According to different hospitals and regions, the cost of IVF usually ranges from tens of thousands to hundreds of thousands of yuan, excluding follow-up monitoring and nursing costs. In addition, IVF babies need to spend a long time for treatment and waiting for results. Usually, it takes months or even years from the start of treatment to the final success or failure. Natural pregnancy does not require additional costs and time costs.

Summary

The procedure of IVF is very different from that of natural pregnancy. IVF is conceived through assisted reproductive technology in the laboratory, which requires medical intervention, drug treatment and multiple operations. In contrast, natural pregnancy is the natural completion of the pregnancy process in the female body. IVF has a low success rate, high cost and time, and there are also some follow-up problems. Therefore, when choosing the birth mode, couples need to comprehensively assess their own conditions and risks, and make decisions under the guidance of doctors.
