For whom?
IVF is a kind of assisted reproductive technology, which enables infertile couples to become pregnant through in vitro fertilization. However, not all infertile couples are suitable for IVF. So, who is suitable for IVF? The following will be detailed from four aspects: age, infertility cause, genetic disease and assisted reproduction experience.

Age
The age of women is one of the key factors affecting the success rate of IVF. Generally, the success rate of IVF for women under 35 years old is higher than that for women over 35 years old. With the increase of age, the number and quality of female eggs will decline, leading to the reduction of fertilization rate and implantation rate, increasing the risk of miscarriage and chromosomal abnormalities. Therefore, older women are more suitable to choose IVF technology to solve the problem of infertility.
In addition, the age of men will also have a certain impact on the success rate of IVF. Research shows that male aging will lead to a decline in the number and quality of sperm, which in turn affects the fertilization rate and implantation rate. Therefore, older men should also consider using IVF technology.
Causes of infertility
IVF is suitable for couples with various causes of infertility. Infertility problems caused by various reasons can be solved through IVF technology.
If women are infertile due to ovulation disorders, oviduct problems, uterine abnormalities and other reasons, IVF can combine sperm and eggs through in vitro fertilization, and then transfer the fertilized eggs to the female uterus to achieve pregnancy.
If male infertility is caused by insufficient sperm number, low sperm activity and other reasons, IVF technology can be used to combine sperm and eggs in vitro to improve fertilization rate and implantation rate.
Couples who both have infertility factors, such as low sperm activity and low female ovarian function, can also choose IVF technology to solve the problem of infertility.
Genetic disease
If there are genetic diseases or chromosomal abnormalities in couples, IVF technology can reduce the risk of transmission of genetic diseases through selective screening and genetic testing.
Through IVF technology, doctors can screen embryos carrying genetic diseases through pre implantation genetic diagnosis of embryos, and select healthy embryos for transplantation, so as to reduce the possibility of infertile couples having sick children.
Assisted reproduction experience
For those couples who have tried other assisted reproductive technologies such as ovulation induction and IVF but failed to conceive, IVF is a feasible option.
Test tube baby technology is an efficient assisted reproduction technology. For those couples who have failed in assisted reproduction technology for many times, test tube baby technology provides a more effective solution.
Summary
Through the above description, it can be clearly pointed out that IVF is suitable for the following groups: older women and men, couples with infertility causes, couples with genetic diseases, and couples who have tried other assisted reproductive technologies but failed. For these people, IVF technology provides a feasible way to solve the problem of infertility.
