What is the difference between IVF and natural pregnancy
Test tube baby is a kind of birth mode realized by artificial assisted reproduction technology. Compared with natural pregnancy, there are some significant differences. This article will elaborate on these differences from in vitro fertilization, success rate, maternal health and transmission of genetic diseases.
1、 In vitro fertilization process
In vitro fertilization (IVF) is the core step of IVF, which is obviously different from natural conception. In natural pregnancy, sperm and eggs are naturally combined and fertilized in the female body, but during IVF of IVF, female eggs will be taken out and combined with male sperm in the laboratory. This process is controlled manually, usually including female ovulation guidance, egg collection, sperm acquisition and in vitro fertilization.
In addition, the process of in vitro fertilization usually involves embryo culture, that is, the fertilized eggs are cultured for several days in the laboratory until the embryo has reached a certain stage of development before being implanted into the female uterus to achieve pregnancy. This process is more finely regulated than natural pregnancy.
Therefore, there are significant differences between IVF and natural pregnancy.
2、 Difference in success rate
IVF has improved the fertility opportunities of infertile couples to some extent, but its success rate is different from that of natural pregnancy.
According to medical research data, the success rate of IVF is usually about 30% to 50%, while the success rate of natural pregnancy is about 20% to 30%. This means that the success rate of IVF is slightly higher than that of natural pregnancy.
However, the success rate of IVF is still affected by many factors, including age, reproductive health, etc. Therefore, not every couple is suitable to choose IVF as a fertility method.
3、 Health considerations for pregnant women
Compared with natural pregnancy, the birth mode of IVF may have a certain impact on the health of pregnant women.
First of all, in the process of IVF, women may need to be treated with ovulation guidance. These drugs may have some regulating effects on women's endocrine system, and may have some side effects.
Secondly, after the success of IVF, pregnant women may need to receive more intensive monitoring and treatment from doctors to ensure the normal development of embryos and the health of pregnant women. This may bring some psychological and physiological pressure to pregnant women.
Therefore, the health of pregnant women needs to be comprehensively considered, and professional doctors should give reasonable guidance and suggestions.
4、 Risk of transmitting genetic diseases
The fertilization process of IVF usually requires the use of donated sperm or eggs, which may bring some risks of genetic diseases.
In natural pregnancy, the risk of genetic diseases between parents has a certain probability through gene transmission. In the IVF mode of reproduction, donated sperm or eggs may also introduce the risk of some genetic diseases into the baby's genome.
Therefore, when choosing IVF as the mode of reproduction, strict evaluation and screening are required to reduce the risk of genetic diseases.
Summary
Compared with natural pregnancy, IVF is significantly different in many aspects, such as the process of IVF, success rate, maternal health and genetic disease risk.
Although IVF provides a birth opportunity, its success rate is limited and there are certain requirements for the health of pregnant women. In addition, the use of donated sperm or eggs may bring about the risk of genetic diseases, which requires comprehensive evaluation and screening.
Therefore, when choosing the mode of reproduction, individuals need to receive relevant treatment and consultation in appropriate hospitals according to their own conditions, doctor's advice and professional assisted reproductive technology.
