Indications and applicable population of IVF
In vitro fertilization (IVF) refers to the method of implanting the fertilized egg into the female uterus after in vitro fertilization of female eggs and male sperm, so as to achieve a healthy baby for infertile couples. IVF technology has been widely used, and the indications are increasing. The following will elaborate on the indications and applicable population of IVF from four aspects: the cause of infertility, female age, genetic diseases and the demand for IVF.

Causes of infertility
Infertility refers to the condition that both husband and wife still fail to conceive naturally after a certain period of normal sexual life. There are many reasons for infertility, including male sperm quality problems, female egg quality problems, fallopian tube blockage, endometrial problems, and so on. IVF technology can help these infertile couples solve their fertility problems, so IVF is a very adaptive method for the causes of infertility.
Female age
The age of women is one of the important factors affecting the ability to conceive. With the growth of age, the quality and quantity of female eggs will gradually decline. Especially for women aged 34 and above, the decline of egg quality is more obvious. Therefore, for older women, IVF technology is a very suitable method to achieve fertility aspirations.
Genetic disease
Some genetic diseases will have a serious impact on the health of offspring, even endanger life. If both husband and wife carry the gene of a genetic disease, their children may suffer from this disease. Through IVF technology, doctors can realize gene screening of embryos in vitro, so as to avoid implanting embryos with genetic disease genes into women's uterus and reduce the risk of disease. Therefore, for couples with genetic disease genes, IVF technology is an ideal choice.
Demand for in vitro pregnancy assistance
Some couples may not be able to conceive naturally due to other reasons. This includes single women, same-sex partners and couples in some special circumstances. IVF technology can meet the needs of these people and help them realize their desire to be parents.
To sum up, the technical indications of IVF include the causes of infertility, female age, genetic diseases, and the need for IVF. Applicable population includes infertile couples, older women, couples with genetic disease genes and people who need in vitro pregnancy assistance. The emergence of IVF technology has brought hope for many couples to have children, enabling them to realize their dream of becoming parents.
