The difference between IVF and natural pregnancy
IVF and natural pregnancy are two different ways of reproduction, and they are significantly different in many aspects. This article will elaborate on these two methods from four aspects: physiology, process, success rate and risk.
physiology
IVF transfers the fertilized eggs into the mother's uterus through artificial assistant technology, so its pregnancy mechanism is different from that of natural pregnancy. In vitro babies need to inject hormones into women's bodies to promote the development of multiple follicles, and obtain eggs through egg retrieval surgery, and then combine with sperm in vitro to form fertilized eggs. Then, the fertilized egg will be cultured and tested to select the best embryo to be transferred to the mother's uterus. In contrast, natural pregnancy occurs during sexual intercourse, when sperm and eggs naturally combine in the female body to form a fertilized egg.
In addition, IVF may involve sperm, eggs or uterus provided by a third party, while natural pregnancy depends on the physical conditions of both spouses.
Therefore, the physiological process of IVF is more complicated than that of natural pregnancy, and requires the professional technical support of doctors.
process
The process of natural pregnancy is relatively simple, which only requires the couple to have normal sexual behavior. The process of IVF needs to go through several steps: women promote the development of eggs by injecting hormones at a specific period of the menstrual cycle, then obtain eggs through egg retrieval surgery, combine with sperm in vitro to form fertilized eggs, and finally select the best embryo to transplant into the female uterus.
The whole process of IVF requires multiple medical examinations and operations, while natural pregnancy is more convenient.
Success rate
There are also some differences in the success rate between IVF and natural pregnancy. The success rate of IVF is relatively low because IVF needs to go through multiple steps of manual operation. According to medical research, the success rate of IVF is usually between 30% and 40%, which is also affected by many factors, such as women's age, health status and treatment methods.
The success rate of natural pregnancy is usually high, especially for the people with good physical conditions and moderate age, the probability of pregnancy is higher.
risk
There are certain risks in the process of IVF. First of all, women may have discomfort or complications in the process of hormone injection to promote egg development. Secondly, ovum retrieval may cause ovarian hyperstimulation syndrome, which may lead to ovarian swelling and abdominal pain. Third, the IVF process also brings psychological pressure and uncertainty.
In contrast, the risk of natural pregnancy is low, and the risk mainly comes from complications during pregnancy, such as abortion, fetal malformation, etc. However, these risks also exist in IVF.
summary
There are significant differences in physiology, process, success rate and risk between IVF and natural pregnancy. IVF pregnancy through artificial assistant technology requires professional support from doctors, and the process is complex, with low success rate and high risk. Natural pregnancy is the natural pregnancy of couples under normal sexual behavior. The process is simple, the success rate is high, and the risk is low.
