Definition and application of IVF
In vitro fertilization (IVF) refers to the transfer of fertilized eggs into the mother's body to give birth to a baby. It is an assisted reproductive technology. For couples with infertility, it is a choice to solve fertility problems. IVF technology can help couples who are difficult or impossible to conceive naturally realize their dreams of becoming parents.

Application field 1: female factor infertility
IVF technology is widely used in the treatment of female factor infertility. Female factor infertility may be caused by low ovarian function, ovulation disorder or fallopian tube obstruction. Through IVF technology, doctors can take measures to promote ovarian function, monitor the ovulation cycle, collect eggs at an appropriate time, and then combine with sperm in the laboratory for in vitro fertilization. After the fertilized eggs are cultured, select high-quality embryos to transfer to the mother to increase the success rate.
However, IVF technology is not applicable to all women's problems. For those women who are unable to produce eggs due to complete ovarian failure, they may need to use the method to achieve fertility.
Application field 2: male factor infertility
In addition to female factors, IVF technology can also help male infertile couples. Male infertility may be caused by low sperm quality or quantity. In this case, doctors will recommend sperm donation, that is, obtaining sperm from donors for in vitro fertilization and embryo transfer.
In addition, for male infertility caused by genetic abnormalities, IVF technology can also be used in gene screening and embryo selection to reduce the risk of genetic diseases.
Application field 3: complex infertility
IVF technology is also applicable to the treatment of complicated infertility. Complex infertility may be caused by multiple factors, including female factors, male factors and other unknown reasons. Through the comprehensive use of assisted reproductive technologies, such as in vitro fertilization and embryo transfer, doctors can increase the chances of successful pregnancy.
For patients with complex infertility, IVF technology can also be combined with other auxiliary means, such as the freezing of eggs or sperm, for use at a future point in time.
Application field 4: infertility research and innovation
The application of IVF technology also includes research and innovation in the field of infertility. Through continuous research and improvement of technology, the medical community can improve the success rate of IVF technology, reduce the risk of complications, and develop new assisted reproductive technologies.
With the continuous development of IVF technology, many infertile couples have hope. However, the technology still has certain risks and limitations, and needs to be carried out under the guidance of professional doctors. In the future, with the further development of medical technology, we can expect IVF technology to make greater breakthroughs in the field of infertility.
Summary
IVF is a method to help infertile couples achieve fertility through in vitro fertilization. It is applicable to the treatment of female factor infertility, male factor infertility and complex infertility, as well as infertility research and innovation. The application of IVF technology continues to expand, bringing hope and opportunities to many infertile couples.
