Restrictions on IVF
With the continuous development of science and technology, IVF has become a relatively common assisted reproductive method. However, for various reasons, IVF is not an option that all couples can choose. Next, we will elaborate on the restrictions of IVF from four aspects.

Age limit
Age is one of the primary restrictions for IVF. The reproductive capacity of women is declining with the growth of age. It is generally believed that women over 35 years old will have significantly increased difficulty in pregnancy. Therefore, many hospitals will set an age limit, usually around 40 years old. In addition, the male reproductive capacity is also affected by age, but the impact is relatively small, generally there is no clear upper limit.
The reason for the age limit of IVF is that with the increase of age, the female ovarian function gradually declines, the quality and quantity of eggs decrease, and the success rate of fertilization and implantation will also decrease. By limiting the age, the success rate of IVF can be improved.
It is worth noting that age is only an overall consideration, and the specific age limit may vary depending on individual physical conditions and hospital policies.
Physical health
Physical health is another important limitation of IVF. Women need to assess their fertility and physical health through a series of examinations, including ovarian function, uterine morphology, endometrial thickness, etc. Different health conditions may have different effects on the success rate of IVF.
Similarly, men also need to conduct semen analysis to assess the number, vitality and morphology of their sperm, as well as whether there are other fertility disorders. These tests can help doctors judge whether it is suitable for IVF.
In addition, some chronic diseases such as diabetes and cardiovascular diseases may also affect the implementation of IVF. Therefore, before choosing IVF, doctors will consider the health status of the couple comprehensively.
economic condition
IVF is a relatively complex and expensive medical technology, which requires multiple medical operations and a series of drugs. Therefore, economic conditions have become an important consideration for many couples to choose IVF.
The cost of IVF varies from country to country, but it is generally more expensive than the process of normal natural pregnancy. In addition, IVF babies sometimes need several attempts to succeed, which will further increase the economic burden.
Therefore, when choosing IVF, couples need to consider their own economic capacity, as well as the cost support policies of hospitals and insurance.
Psychological preparation
Psychological preparation during IVF is also an important limiting condition. IVF needs to go through a series of medical processes and may face the pressure of failure and uncertainty. At the same time, for some couples, IVF may mean giving up the possibility of natural reproduction, which will bring some emotional pressure.
Therefore, before deciding to carry out IVF, couples need to evaluate their psychological endurance and make corresponding psychological preparations. Some hospitals will provide psychological counseling services to help couples cope with these psychological pressures.
Summary
As an assisted reproductive method, IVF has certain restrictions on the physical condition, economic ability and psychological preparation of couples. Age limit, physical health condition, economic condition and psychological preparation are the main limiting factors. Couples should consider these factors comprehensively when choosing IVF and make decisions under the guidance of doctors.
