Comparison of three generations of IVF and natural pregnancy
At present, three generations of IVF technology has become a common assisted reproduction mode. However, compared with natural pregnancy, the third generation IVF may cause greater pain in some aspects. This article will elaborate the difference of the pain degree between the three generations of IVF and natural pregnancy from four aspects of physiology, psychology, economy and society.

Physiological aspects
In terms of physiology, the third generation IVF usually needs a series of medical examinations and treatments, which may include the injection of pretreatment drugs, egg collection surgery, embryo transfer and other processes. These processes may impose certain burdens and pains on women's bodies. For example, ovarian puncture is required for egg collection, which may cause abdominal pain and discomfort.
In contrast, natural pregnancy only requires sexual life, without medical operation, and has less burden on women's body. Although there may be some physiological pain during natural pregnancy, such as labor pains during childbirth, the overall pain level is lower than that of the third-generation IVF.
Psychological aspects
Psychological aspect is another important factor that affects the degree of pain of the third generation IVF. Infertility is a great psychological pressure and pain for both husband and wife. The choice of third-generation IVF technology may require long-term treatment and waiting, which puts forward higher requirements for the psychological endurance of both spouses.
Couples who are naturally pregnant can rely on the passage of time and continuous efforts to achieve the goal of pregnancy. Relatively speaking, it is easier to adjust their mentality. Therefore, from a psychological point of view, natural pregnancy may cause less pain to both spouses. In contrast, three generations of IVF may bring more psychological pressure and pain to both spouses.
Economic aspects
Three generation IVF babies usually need multiple treatments and examinations, which may involve the costs of multiple medical institutions and professional doctors, and the treatment process may take a long time. This means that three generations of IVF babies may bring heavy financial burden to families.
The economic cost of natural pregnancy is relatively low, just keep good living habits and intimate relations at the right time. Therefore, the economic burden is relatively small, and the degree of pain is lower than that of three generations of IVF.
Social aspects
The use of third-generation IVF technology needs to openly talk about infertility in society, and may face challenges and discrimination from others. Couples who choose third generation IVF babies may face the judgment and pressure of society on their decision-making.
In contrast, natural pregnancy does not require special technology and treatment, more in line with the traditional way of reproduction, and will not cause social concern and evaluation. Therefore, the social aspect has little impact on couples who are naturally pregnant. Relatively speaking, three generations of IVF babies may face greater social pain.
Summary
In terms of physiology, psychology, economy and society, the three generations of IVF babies may bring more pain than natural pregnancy. However, every couple's situation is different. For some infertile couples, three generations of IVF may be the only way to realize their dream of fertility. Therefore, the evaluation of the degree of pain should be subjective and individualized.
