Age related success rate of older IVF infants
With the progress of modern medical technology, IVF technology has become the gospel of many infertile couples. However, the success rate of IVF is affected by many factors, among which age is an important factor. Age has a significant impact on women's fertility. The following will elaborate on the age-related success rate of older IVF infants from the aspects of physiological mechanism, change of success rate, clinical experience and hospital cases.
physiological mechanism
The quality of female reproductive organs and eggs gradually declines with age, which is one of the main reasons for the decline of the success rate of older IVF. Women's eggs have been formed at birth, and the number cannot be regenerated. At the same time, the quality will be affected with the growth of age. Older women, whose egg quality is generally poor, are prone to chromosomal abnormalities or genetic diseases, which increases the risk of IVF failure.
In addition, the uterine environment of women will also be affected by age. With the growth of age, endometrial thinning, decreased blood supply, insufficient congestion and other problems may lead to implantation failure. These changes in physiological mechanisms together led to the decline in the success rate of older IVF infants.
Change in success rate
Research shows that the success rate of IVF for older women is significantly lower than that for younger women. Long term observation has found that after the age of 35, the annual pregnancy rate of women has dropped by 5%, and by the age of 40, it has dropped to about 50%. The success rate of IVF for women after 45 years old is almost zero, which is directly related to age-related physiological changes.
In addition, older women need to use large doses of drugs in the process of IVF, and the ovarian stimulation effect is poor, which makes the egg quality worse, thus reducing the success rate. At the same time, aging is often accompanied by other chronic diseases, such as hypertension, diabetes, etc. These diseases will also have a negative impact on the success rate of IVF.
clinical experience
Clinical experience shows that older women need to be more cautious and precise when carrying out IVF, and the medical team needs to make more detailed planning and operation on ovarian stimulation, egg collection, embryo transfer and other links. At the same time, older women may need more auxiliary technical support in the process of IVF, such as embryo screening. The summary and practice of these clinical experiences have improved the success rate of older IVF babies and provided more opportunities for older infertile couples.
Hospital cases
Beijing Obstetrics and Gynecology Hospital is one of the well-known infertility treatment centers in China, with rich experience in IVF. According to the hospital's data, the success rate of IVF for women under 35 years old is about 50%, while that for women over 45 years old is only about 5%. This data confirms the fact that the success rate of older IVF infants is age related.
The clinical team of Beijing Obstetrics and Gynecology Hospital carried out a standardized IVF program for elderly women, including the use of ovarian stimulators, the selection of embryo transfer opportunities, etc. These personalized treatment programs have helped the elderly women improve the success rate of IVF, and realized the dream of healthy babies for many couples.
Summary
The success rate of older IVF infants is related to age, and this phenomenon can be explained by physiological mechanism, change of success rate, clinical experience and hospital cases. Age has an impact on female egg quality and uterine environment, leading to the reduction of the success rate of older IVF. However, the continuous practice and experience summary of the hospital provide more opportunities for elderly women to realize their dream of healthy babies.
