Is the success rate of IVF related to age?
IVF is a kind of assisted reproductive technology, which is widely used to help couples who cannot conceive naturally realize their desire to have children. However, many people have doubts about the success rate of IVF and the impact of age on it. This article will elaborate on this issue from the aspects of success rate, female age, male age and hospital technology.
1. Success rate
The success rate of IVF is one of the important indicators to consider its effect, and many factors will affect it. First, women's age is related to success rate to some extent. Statistics show that the success rate of IVF is higher when women are under 35 years old, but the success rate shows a downward trend with the increase of age. This is mainly due to the decline of female egg quality, number of follicles and follicular reactivity with age. Secondly, the quality and quantity of male sperm will also affect the success rate of IVF. If men have problems such as testicular dysfunction and poor sperm quality, the possibility of fertilization will be reduced.
In addition, the etiology of some patients will also affect the success rate of IVF. For example, women with problems such as tubal obstruction and endometriosis, or men with severe semen abnormalities, will have adverse effects on embryo implantation and development, thus reducing the success rate.
However, the success rate is not absolutely fixed, because everyone's physical condition and physiological characteristics are different, and some factors can be adjusted and treated to improve the success rate.
2. Female age
Female age is one of the important factors affecting the success rate of IVF. The quality of young women's eggs is usually good, and the number is relatively large, so the success rate is high. According to the American Society of Reproductive Medicine, the success rate of IVF for women aged 25-29 years is about 40-45%, while that for women aged 35-39 years drops to 30-35%. The success rate of women over 40 years old has further decreased, ranging from 15-20%.
Experts in gynecology and obstetrics pointed out that women gradually reduce the reserve of eggs and the quality of follicles is one of the main reasons. When women are over 35 years old, the number of eggs gradually decreases, the quality of follicles declines, and the success rate of fertilization, implantation and development decreases significantly. Therefore, before deciding to carry out IVF, women should consult and check as soon as possible to understand their fertility index and possible problems.
3. Male age
Compared with female age, male age has a relatively small impact on the success rate of IVF. However, with the growth of age, the male reproductive system will also decline to a certain extent. For example, the quality and quantity of sperm may decline, affecting the success rate of fertilization and embryo development. In addition, male testicular dysfunction, reproductive tract infection and other problems will also have a negative impact on the success rate of IVF.
Although male age has little impact on IVF, the health status and reproductive capacity of both the couple should be comprehensively examined to ensure that any potential problems can be found and dealt with accordingly during the treatment process.
4. Hospital technology
The success rate of IVF is also closely related to the technical level of the hospital. At present, there are many well-known reproductive hospitals around the world with rich experience in IVF treatment and advanced technical equipment. These hospitals have improved the success rate of IVF through continuous technological updating and innovation.
Many medical institutions at home and abroad have accumulated rich experience in the field of IVF. For example, Beijing Union Medical College Hospital, Fudan University Maternity Hospital and other well-known hospitals have high technical level and reputation in IVF treatment. Choosing a hospital with good reputation and advanced technology for IVF treatment is very important to improve the success rate.
Summary
In conclusion, the success rate of IVF is related to age. Women's age has a greater impact on the success rate, which will gradually decline with the increase of age. The influence of male age on the success rate is relatively small, but attention should also be paid to their reproductive system function. In addition, the level of hospital technology is also an important factor affecting the success rate. In order to improve the success rate of IVF, couples should consult professional doctors as soon as possible and choose formal medical institutions for treatment.
