Applicable conditions of IVF
IVF is a kind of assisted reproductive technology, which aims to help couples who are unable to conceive naturally due to fertility barriers to achieve pregnancy and fertility aspirations. However, not all couples are suitable for IVF, because this technology has certain restrictions. This article will elaborate on the applicable conditions of IVF from four aspects: age, physical health, marital stability and psychological status.

Age limit
Age is an important applicable condition. For women, age is the key factor affecting the ability to conceive. The reproductive capacity of women gradually declines after the age of 30, especially after the age of 35. Therefore, generally speaking, women under 35 years old, especially couples under 30 years old, are suitable for IVF. In addition, age also has an impact on the quality of men's sperm, so men's age also needs to be considered, but compared with women, men's reproductive capacity declines more slowly.
However, in some cases, older couples can still have IVF, but other factors, such as health status, need to be considered comprehensively.
Physical health restrictions
Health is one of the important conditions for IVF. First, women need to have a normal menstrual cycle and ovulation function to ensure the possibility of pregnancy. Secondly, women's uterus and fallopian tubes need to be normal, without structural problems caused by congenital abnormalities or diseases. Finally, women need to rule out serious gynecological diseases, such as ovarian dysfunction, endometriosis, etc.
For men, sperm quality is a key factor. Men need a sufficient number and vitality of sperm to improve the success rate of IVF. If men have low sperm quality and other problems, they may need to use other assisted reproductive technologies to solve them.
Marriage stability restrictions
Marriage stability is also one of the important conditions for IVF. IVF needs the close cooperation and support of couples, because the whole process requires couples to jointly bear and face possible pressure and difficulties. If there are marital instability or emotional problems between couples, it may have a negative impact on the success rate of IVF and the subsequent childcare process.
In addition, in some countries and regions, IVF may require couples to provide marriage certificates or legal documents to prove the legitimacy and stability of their marriage.
Mental status limitations
The psychological status of the couple is also an important consideration for IVF. The process of IVF may bring some psychological pressure and emotional fluctuations, and couples need to have sufficient psychological endurance and coping ability. If the couple has serious psychological problems, depression or anxiety, psychological counseling and evaluation may be required before IVF.
In general, IVF is a complicated and costly reproductive method, which is not suitable for all couples. Age, physical health, marital stability and psychological status are the four important restrictions. Respecting these restrictions can ensure the success rate of IVF and the physical and mental health of both spouses.
