Physiological differences between IVF and natural pregnancy
IVF refers to the babies born through IVF technology, while natural pregnancy refers to the cases of natural pregnancy through sexual behavior. There are significant differences between IVF and natural pregnancy in physiological process, success rate, risk to mother and infant, etc.
Different success rates
The success rate of IVF is relatively low. According to the data of the World Health Organization, the success rate of IVF is about 30%, which means that not every couple who try IVF can successfully conceive. However, the success rate of natural pregnancy is relatively high. As long as the couple is at the childbearing age and has no fertility disorder, the probability of success is relatively high.
Of course, the success rate of IVF is also affected by other factors, such as women's age, weight, existing health problems and other factors will affect the results of IVF. Therefore, between choosing IVF and natural pregnancy, couples should make decisions according to their own conditions and the doctor's advice.
Egg retrieval and embryo implantation process
The process of IVF includes several stages, including egg retrieval and embryo implantation. During egg retrieval, women receive hormone therapy to increase the number of eggs, and then puncture the ovary in the operating room to remove the eggs. The process of egg retrieval may cause some discomfort and pain to the female body.
And natural pregnancy does not need to go through any process of egg retrieval, just through normal sexual behavior to let sperm and eggs combine. This method is more natural and simple than IVF.
In the embryo implantation stage, the obtained egg will be fertilized with sperm in vitro to generate an embryo, and then the embryo will be implanted into the female uterus in a non-surgical way. This process requires certain technical and equipment support.
Impact on maternal health
IVF has a heavy physiological and psychological burden on the mother. Ovarian hyperstimulation syndrome may be a complication of ovum retrieval. Due to the low success rate of IVF, multiple attempts are needed, which also increases the burden and risk of women's bodies.
In contrast, natural pregnancy does not pose a significant risk to maternal health. Normal sexual behavior will not have a negative impact on women's body. As long as women maintain good living habits and health, natural pregnancy is relatively safe for the mother.
Risk to infants
Compared with natural pregnancy, IVF has a slightly higher risk for infants. Studies have shown that in vitro fertilization and embryo implantation may increase the risk of birth defects and pregnancy complications in newborns. However, this risk is relatively low and still within the acceptable range.
Infants with natural pregnancy are relatively healthier, because the process of natural pregnancy is based on natural physiological mechanisms, and there is less intervention in embryonic development.
Summary
There are significant differences between IVF and natural pregnancy in terms of physiological differences, success rates, risks to mothers and infants, etc. The success rate of IVF is low, and the risk to mother and infant is relatively high. In contrast, the success rate of natural pregnancy is higher and the risk to mother and baby is lower. Couples should choose their own way according to their own conditions and the doctor's advice.
