Applicable age of IVF
IVF is a kind of assisted reproductive technology, which is applicable to many couples in the case of natural pregnancy difficulties or inability to conceive. However, there are some discussions and disputes about whether the applicable age of IVF includes 45 year old women. The following will elaborate on this issue from the aspects of age, physical condition, medical technology and hospital policy.

Age factor
Age is an important factor, which affects the quality and quantity of female eggs. According to statistics, female fertility gradually declines after the age of 35. Therefore, in general, many hospitals will stipulate that the applicable age of IVF is below 45 years old. This is because the number and quality of follicles decrease as women grow older, which makes it more difficult to conceive. However, due to individual differences, some women may still be able to carry out IVF successfully after the age of 45.
For example, the American IVF Association pointed out that some hospitals may consider receiving IVF treatment for women over 45 years of age after comprehensive assessment of the patient's physical condition and physiological age. This indicates that the decision whether to carry out IVF is not only dependent on age factors, but also includes the comprehensive assessment of other physical conditions.
Physical condition
In addition to age, physical condition is also an important consideration for the applicable age of IVF infants. Some diseases, health problems or surgical history that affect female fertility may limit the applicable age of IVF.
For example, for some women with chronic or genetic diseases, doctors may suggest that they are not suitable for IVF. In addition, for some older women or women with serious gynecological problems, doctors may suggest that they are not suitable for IVF, because this may increase the risk of pregnancy and childbirth.
Medical technology and hospital policy
The applicable age of IVF is also affected by medical technology and hospital policies. Different hospitals may have different regulations and policies. Some hospitals may be more strict, accepting only younger women for IVF, while others may be more flexible, depending on the circumstances.
For example, Beijing New Era Reproductive Medicine Research Institute is a well-known reproductive medicine institution in China. They stipulated in the hospital policy that the applicable age of IVF is 20-45 years old, that is, women under 45 years old can have IVF. This indicates that some hospitals may provide the opportunity for older women to have IVF based on the existing technology and medical background.
Summary
To sum up, in general, the applicable age of IVF does not include women over 45 years old. Age, physical condition, medical technology and hospital policy will all affect whether IVF can be carried out. Therefore, if women over 45 years old want to try IVF, it is recommended to consult a professional reproductive doctor for comprehensive evaluation to determine whether it is suitable for this technology.
