The difference between IVF and natural pregnancy
IVF is one of the assisted reproductive technologies, which combines sperm and egg through in vitro fertilization, and then implant the fertilized egg into the uterus of women to achieve pregnancy and delivery. Compared with traditional natural pregnancy, IVF is obviously different in many aspects.

1. Differences in the way of conception
Natural pregnancy is produced by sexual behavior. Sperm combines with ovulated eggs through natural physiological channels such as vagina, cervix, uterus and fallopian tube, and finally fertilizes and implants. The IVF is carried out in the laboratory. After in vitro fertilization, the embryo develops in the culture medium, and then is implanted into the woman's uterus.
Compared with natural pregnancy, IVF is more accurate and controllable. By controlling the combination of eggs and sperm, some infertility problems can be effectively solved and the pregnancy success rate can be improved.
2. The process of pregnancy and childbirth
The pregnancy and delivery process of natural pregnancy is the continuation of natural laws. In most cases, women go through the normal pregnancy process and then complete the delivery under the supervision of obstetrics. However, the pregnancy and delivery of IVF may be a long lost dream for many couples.
The pregnancy process of IVF requires regular observation and medical examination to ensure the normal development of the embryo. In some cases, assisted reproductive technologies, such as frozen embryo transfer or hormone therapy, may be needed to promote pregnancy. At the same time, IVF delivery may require more medical intervention than natural delivery.
3. Differences between science and economy
IVF is a high-tech medical technology that requires professional doctors, equipment and laboratory support. In modern society, many hospitals provide IVF services, such as Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine in China. By providing high-quality medical facilities and personnel, these hospitals help couples who are unable to conceive in a natural way to achieve their reproductive aspirations.
Compared with natural pregnancy, IVF may be more expensive. In addition to medical expenses, it is also necessary to consider the costs of assisted reproductive technology, such as in vitro fertilization, embryo freezing and preservation. Therefore, for families with financial pressure, choosing IVF may require more consideration.
4. Differences between psychological and emotional levels
The process of IVF may create additional pressure and challenges to the couple's psychology and emotions. For those couples who have been expecting to be pregnant for a long time, IVF may be an opportunity to realize their dreams, but at the same time, they may also face the impact of hopes, anxieties and disappointments.
In the process of IVF, couples need to face special views and pressures from society, family and friends. They need to support each other, maintain a good psychological state, and appropriately seek the help of professional psychological counseling.
summary
Compared with natural pregnancy, IVF has obvious differences in the mode of pregnancy, the process of pregnancy and delivery, the scientific and economic level, and the psychological and emotional level. As an important achievement of modern medical technology, IVF provides hope for couples who cannot conceive through natural means. However, for couples who choose IVF, they need to fully understand and weigh these differences in order to make decisions suitable for themselves.
