The difference between IVF and natural pregnancy
IVF and natural pregnancy are two different ways of reproduction, each with its own characteristics and different advantages and disadvantages. This article will make a detailed comparison between IVF and natural pregnancy from four aspects.
1. Birth mode
Natural pregnancy refers to the natural combination and fertilization of sperm and eggs through sexual life at the right time of a woman's menstrual cycle, and then the embryo is embedded in the inner wall of the uterus to develop and grow. This is a natural way of reproduction.
In vitro fertilization (IVF) is used to fertilize sperm and eggs in the laboratory of the hospital, and then the embryo is cultured to a certain stage and implanted into the inner wall of the female uterus. IVF needs doctors' assistant technology to achieve pregnancy.
The essential difference between natural pregnancy and IVF lies in the different fertilization methods, one is natural fertilization, the other is in vitro fertilization.
2. Success rate
The success rate of natural pregnancy is affected by many factors, including female age, fertility, sperm quality, etc. According to statistics, the success rate of natural pregnancy is about 10% to 25% per cycle. But with the growth of women's age, the success rate will gradually decrease.
The success rate of IVF depends on many factors, including female age, embryo quality, uterine environment, etc. Generally speaking, the success rate of IVF is higher than that of natural pregnancy, but there are also great individual differences. According to different hospitals and technologies, the success rate of IVF is between 30% and 60%.
3. Time and process
Natural pregnancy does not require special time and process, but only requires that both husband and wife maintain a healthy lifestyle, choose appropriate sexual life time, and fertilize sperm and eggs under natural conditions.
IVF needs to go through a series of special processes, including hormone therapy, egg retrieval, in vitro fertilization, embryo culture and implantation. These processes need to be carried out in hospitals, and time and drug use need to be strictly controlled.
4. Application
Natural pregnancy is suitable for most couples. As long as both parties are healthy and have normal fertility, they have the opportunity to have natural pregnancy. For some young couples, natural pregnancy may be the best choice.
Test tube babies are suitable for couples with fertility disorders or infertility. For example, under the conditions of female oviduct obstruction, male sperm quality abnormality, and older women, IVF is an effective assisted reproductive technology.
summary
IVF and natural pregnancy are both ways to achieve fertility, and they have different advantages and applications. Natural pregnancy is a natural way of reproduction, with a low success rate; IVF is a kind of in vitro fertilization, which has a high success rate but needs a special process. Different couples can choose the appropriate birth mode according to their own conditions to realize their own wishes.
