Age limits for IVF infants
IVF technology is a kind of assisted reproductive technology, which can help couples who cannot conceive naturally realize their reproductive dreams. However, due to physiological and psychological factors, IVF is not suitable for couples of all ages. At the same time, different hospitals have different age requirements for IVF. This article will take the Ninth People's Hospital as an example to elaborate on the age limit of IVF from four aspects: the preparation stage, female age limit, male age limit and special hospital regulations.

Preparation phase
IVF is a complex process, which requires couples to conduct a comprehensive physical examination and assessment in the preparation stage. First, couples need to ensure that they are healthy and free from any potential chronic or genetic diseases. Secondly, they should also carry out psychological counseling to understand the pressure and emotional changes in the process of IVF, and make psychological preparations.
Female age limit
Female age is one of the key factors in IVF. Generally speaking, the success rate of women under 35 years old is relatively high, the success rate slightly drops between 35-40 years old, and it is more difficult for women over 40 years old. This is because the number and quality of female eggs will decline with age, thus affecting the success rate of pregnancy and embryo implantation. Therefore, in the Ninth People's Hospital, the age of women is generally limited to 40 years old.
Male age limit
Although the relationship between male fertility and age is not obvious, age also has a certain impact on the quality and quantity of male sperm. With the increase of age, the quality of male sperm may decline, which affects the quality of pregnancy and embryo. However, compared with women, male fertility is subject to fewer age restrictions. In the Ninth People's Hospital, there is generally no clear upper limit for male age, but doctors will make assessment and suggestions according to the actual situation.
Special hospital regulations
As a well-known reproductive hospital, the Ninth People's Hospital has some special regulations on the age limit of IVF. First of all, for women over 40 years old, the hospital will require more detailed examination and evaluation to assess their suitability. Secondly, for couples with a history of genetic diseases or other special circumstances, the hospital will more carefully assess their health status and fertility prospects. Finally, according to the specific situation of the couple, the hospital will develop a personalized treatment plan in combination with other assisted reproductive technologies, such as egg or sperm donation.
Summary
The age limit of IVF is based on physiological and psychological factors. The Ninth People's Hospital requires that the age of women is generally limited to less than 40 years old, and there is no clear upper limit for the age of men. However, for couples in special circumstances, the hospital will conduct more detailed assessment and professional advice. In the preparation stage, couples need to carry out comprehensive physical examination and psychological counseling to ensure physical health and psychological preparation. There may be differences between the age limit of IVF and that of hospitals. Patients should be aware of relevant regulations when choosing hospitals.
