Success rate of IVF
IVF is a kind of assisted reproduction technology, which helps couples who cannot conceive naturally realize their reproductive aspirations by cultivating fertilized eggs in the laboratory and transferring high-quality embryos to their mothers. However, the success rate of IVF is not 100%, and success requires many attempts.

Success rate and age
The success rate of IVF is closely related to female age. The quality of young women's eggs is better, and they can become pregnant more easily. According to the data of the American IVF Association, the pregnancy rate of IVF for women under 35 years old is about 40% to 50%, while that for women over 40 years old is only 15% to 20%. Therefore, when young women try IVF, the success rate is high.
However, different hospitals and technical levels will also affect the success rate. For example, one of the more famous IVF hospitals in the United States is Boston Hospital, which has advanced IVF technology and an experienced medical team, with a high success rate.
In addition, women with some diseases or other physiological problems, such as polycystic ovary syndrome, endometriosis, may affect the success rate of IVF. These factors need to be comprehensively evaluated and guided by doctors in the process of trying.
Number of attempts and success rate
IVF does not succeed in one attempt. On average, women need two to three attempts to conceive successfully, according to the American Society for Test Tube Infants. However, the success rate will vary depending on individual differences and other factors. Some couples may need to try more, while others successfully conceive on the first try.
The success of IVF is related to many factors, including egg quality, endometrial status, and male sperm quality. Therefore, a professional team of doctors should conduct a comprehensive assessment of the couple's situation, and develop personalized treatment plans to improve the success rate.
Some couples may still fail after trying IVF several times. They can further communicate with doctors to explore other solutions, such as.
Psychological and life support
The IVF process may bring great psychological pressure and emotional fluctuations. Therefore, couples should seek psychological guidance and support to cope with this pressure.
In addition, changing lifestyle and eating habits can also promote the success of IVF. Quitting smoking and drinking, exercising regularly, and maintaining a healthy weight all contribute to improving the success rate.
summary
The success rate of IVF is affected by many factors, such as female age, hospital technical level, individual differences, etc. Young women have a higher success rate when trying IVF, while women over 40 years old have a lower success rate.
