What is the failure rate of IVF?
IVF technology is an important medical means to help infertile couples realize their reproductive dreams. However, due to various factors, IVF is not always successful. This article will elaborate on the failure rate of IVF from four aspects.
Success rate of embryo transfer
The most critical step in IVF is embryo transfer, which is also one of the most frequent failures. The success rate of embryo transfer is closely related to many factors. The first is the age of women. Young women have better ovarian function, higher embryo quality and higher success rate of transplantation. The second reason is infertility, such as uterine abnormalities, uterine fibroids, which can affect embryo implantation. Finally, the quality of embryos. In the process of IVF, the development and genetic health of embryos have an important impact on the success rate of transplantation.
One study shows that the pregnancy rate of test tube babies after embryo transfer is about 30% to 40%. However, successful implantation does not mean successful delivery. There are still some pregnancies that will lead to abortion or other complications.
Failure rate of embryo frozen storage
In the process of IVF treatment, some embryos are sometimes frozen for subsequent transplantation. However, the success rate of embryo cryopreservation is not 100%. Frozen embryos may be damaged in the process of thawing, leading to transplant failure. Moreover, long-term frozen storage will also have a certain impact on the quality of embryos, reducing the success rate of transplantation.
Research shows that the success rate of embryo cryopreservation is about 80% to 85%. The success rate of frozen embryos is closely related to freezing technology, embryo quality, storage time and other factors.
Test tube infant cycle failure rate
IVF treatment generally requires multiple cycles, and even under the most ideal conditions, it may not be successful at one time. A study found that about 20% to 30% of infertile couples experienced three or more IVF cycles before they finally succeeded. There are many reasons for IVF cycle failure, including the comprehensive impact of multiple factors.
The failure rate of IVF cycles is closely related to the experience and technical level of hospitals and doctors. Some high-level medical institutions, such as Mayo Clinic in the United States and Peking Union Medical College Hospital in China, can reduce the failure rate of IVF cycle through their rich experience and professional team strength.
Influence of psychological factors on success rate
IVF treatment is a long-term and tedious process. For patients, psychological status is very important. Anxiety, tension and stress may affect the physiological status of patients, thus affecting the success rate of IVF.
The influence of psychological factors is very complex. Therefore, some medical institutions will provide professional psychological counseling services in the process of IVF to help patients relieve pressure, regulate emotions and improve the success rate of treatment.
Summary
The failure rate of IVF is unavoidable, and failure may occur in every link. The success rate of embryo transfer, failure rate of embryo frozen storage and failure rate of IVF cycle are the main reasons for IVF failure. In addition, psychological factors will also have a certain impact on the success rate of IVF.
However, fortunately, with the continuous progress of medical technology and the continuous efforts of professional teams in medical institutions, the success rate of IVF is also increasing. Despite the failure rate, many infertile couples have realized their reproductive aspirations through IVF technology, bringing hope and happiness to more people.
