What is the difference between IVF and natural pregnancy?
In Vitro Fertilization (IVF) is a kind of assisted reproductive technology. Compared with natural pregnancy, there are some significant differences. The following is a detailed description of IVF and natural pregnancy from four aspects: pregnancy mode, pregnant preparation, baby quality and success rate.

1、 Pregnancy mode
The natural way of pregnancy is through sexual behavior. The sperm and egg are free to combine and fertilize in the female body, and then implant and develop into an embryo. In vitro babies, sperm and eggs are combined in the laboratory to form a fertilized egg and then implanted into the female uterus. This way bypasses the process of sexual intercourse, reduces male or female physiological restrictions, and can help couples who are naturally difficult to conceive to achieve pregnancy.
The process of IVF includes ovarian stimulation, egg collection, in vitro fertilization, embryo culture and embryo transfer. Although the mode of pregnancy is different, the process of embryo implantation and development is similar to that of natural pregnancy.
2、 Pregnancy preparation
Natural pregnancy does not require special preparation for pregnant women, just keep good living habits and healthy diet. Test tube babies require pregnant women to carry out relevant examinations and treatment before starting different links. Including ovarian function examination, uterine cavity examination, sex hormone replacement therapy, etc., to ensure that the physical condition of pregnant women is suitable for the IVF program.
In the process of IVF, pregnant women need to take assisted reproductive drugs to promote follicular development and ovulation. In addition, multiple physical examinations and monitoring are required to ensure the success of egg collection and embryo transfer.
3、 Infant quality
The quality of IVF and natural pregnancy is basically the same. Research shows that there is no significant difference in intelligence, physical health and psychological development between IVF and naturally conceived infants. Through reasonable embryo selection and infant culture technology, the IVF program can reduce the risk of some genetic defects and abnormalities.
However, the multiple pregnancy rate of IVF is relatively high. Because IVF often chooses multiple embryo transfer, it may lead to twin, triple or multiple pregnancy. Multiple pregnancies increase the risk of premature delivery, low birth weight and other complications.
4、 Success rate
Compared with natural pregnancy, the success rate of IVF has improved, especially for some couples who are not easy to conceive. The success rate of IVF depends on many factors, including female age, egg quality, sperm quality and embryo quality. According to data from around the world, the success rate of IVF is usually between 30% and 50%.
However, the IVF program is not 100% successful, and failure is also possible. Therefore, couples should fully understand the success rate, risks, costs and other factors, and consult with doctors in detail before deciding to adopt the IVF program.
Summary
To sum up, there are obvious differences between IVF and natural pregnancy in terms of pregnancy mode, pregnant preparation, baby quality and success rate. The IVF program helps couples who are not easy to conceive to realize their desire to have children through assisted reproductive technology. Its success rate is relatively high, but the risk of multiple pregnancy cannot be ignored. When choosing the IVF program, couples should carefully consider and fully understand various factors to make the most appropriate decision.
