Age requirements for IVF infants
IVF is an assisted reproductive technology that can help couples who cannot conceive naturally achieve their reproductive aspirations. In order to ensure the safety and success rate of technology, IVF babies should meet certain age requirements. The following is a detailed description of the age requirements for IVF infants.

Female age requirements
Female age is one of the important factors affecting the success rate of IVF. Generally speaking, when women are under 35 years old, the success rate will be higher. With the growth of age, the quality and quantity of female eggs will gradually decline, thus affecting the quality and implantation ability of embryos. Therefore, the upper limit for IVF in most hospitals is 35-40 years old. However, different hospitals may have different age requirements.
In addition, women's physical health will also affect whether it is suitable for IVF. For example, women with chronic diseases such as severe hypertension and diabetes may not be suitable for IVF, because these diseases will increase the risk of pregnancy complications.
In addition, women's ovarian function also needs to be evaluated. By checking the hormone level of the ovary and the number of follicles, it can be determined whether women have enough eggs for IVF.
Male age requirements
Although female age has a greater impact on the success rate of IVF, male age is also an important factor. The aging of men will lead to the decline of sperm quality and quantity, thus affecting the fertilization ability. Generally speaking, men should be under 50 years old. However, different hospitals may have different age requirements for men.
In addition to age, male semen quality is also an important indicator to determine whether it is suitable for IVF. Male fertility can be assessed by examining sperm concentration, motility and morphology of semen.
Marital time requirements of couples
IVF requires a legal marriage between the couple. This is to ensure that babies can grow up in a suitable family environment and obtain legal parental rights. Before IVF, hospitals usually require couples to show their marriage certificates.
Other medical condition requirements
In addition to age and marriage requirements, there are other medical conditions that need to be met. For example, couples with serious genetic diseases may not be suitable for IVF, because this will increase the risk of infant disease. In addition, couples must undergo comprehensive physical examination and psychological tests to ensure that they are physically and mentally fit for IVF.
To sum up, participating in IVF infants needs to meet certain age requirements. Women should be under 35 years old and men under 50 years old. Couples need to have a legal marriage relationship and pass a comprehensive medical assessment. These age requirements and medical conditions are designed to ensure the success rate of IVF and the health of infants.
