The concept of IVF and natural pregnancy
IVF refers to the process of cultivating embryos through assisted reproductive technology (ART) in vitro fertilization, and then transferring the embryos to the mother's uterus to develop into a baby. Natural pregnancy refers to the combination of sperm and egg through sexual intercourse without any auxiliary technology, and then naturally develops into a baby in the womb.
1. Differences in methods and processes
IVF is carried out in the laboratory. First, doctors will urge women to ovulate more through ovulation promoting drugs, and then collect eggs from women. Next, the doctor combines the egg and sperm in a test tube to culture the embryo until it reaches the appropriate development stage. Finally, doctors transfer the embryo into the mother's uterus. The whole process requires the use of assistive technologies, including in vitro fertilization, embryo culture and transplantation.
Natural pregnancy is completely dependent on the natural physiological process. A man sends sperm into a woman's vagina through sexual intercourse, and then the sperm will swim to the egg itself. If the sperm and the egg are successfully combined, the fertilized egg will be implanted in the woman's uterus and develop into a baby.
This difference in method and process makes IVF pregnancy less likely than natural pregnancy.
2. Difference in pregnancy probability
The pregnancy rate of IVF is generally lower than that of natural pregnancy. Since the IVF process needs to go through multiple stages, including egg collection, in vitro fertilization, embryo culture and transplantation, problems may occur in each stage, leading to pregnancy failure. Natural pregnancy has almost no other links except the combination of sperm and egg.
In addition, the age of IVF will also affect the probability of pregnancy. The age of women is one of the most important factors for the success rate of IVF. With the increase of age, the quality and quantity of women's eggs will decline, thus reducing the probability of successful pregnancy.
In contrast, the pregnancy probability of natural pregnancy is relatively stable, but it is also affected by many factors, such as female egg quality, male sperm quality, ovulation cycle, etc.
3. Impact on pregnancy
The risk of IVF pregnancy may be slightly higher than that of natural pregnancy. Because IVF processes involve hormone therapy, in vitro fertilization and embryo transfer, these processes may have side effects and risks. For example, pregnancy may increase the risk of premature delivery, abortion and multiple births.
Natural pregnancy is relatively natural, without hormone therapy and auxiliary technology, so the risk of pregnancy is low.
4. Psychological and emotional differences
The psychological and emotional pressure during IVF may be greater. For infertile couples, IVF may be the only way to achieve their fertility aspirations. Due to the possibility of multiple failures and the pressure of various treatments and processes in this process, these pressures may bring psychological and emotional burdens to couples.
While natural pregnancy is relatively simple, without the intervention of assistive technology, which is relatively easy and natural for most couples. This natural process may bring more pleasure and satisfaction.
Summary
Compared with natural pregnancy, IVF has obvious differences in mode and process. IVF has a lower probability of pregnancy and a higher risk of pregnancy than natural pregnancy. In addition, the psychological and emotional pressure during IVF is also high. Therefore, the choice of IVF or natural pregnancy should be based on personal circumstances and needs.
