What factors affect the success rate of IVF infants at 40 years old?
In vitro fertilization and embryo transfer (IVF-ET) has become an effective method to understand infertility in recent decades. However, the success rate of IVF is not static and is affected by many factors. This article will elaborate on what factors affect the success rate of IVF at the age of 40 from four aspects.
1. Age factor
Age is one of the important factors that affect the success rate of IVF. With the growth of women's age, the ovarian function gradually declines, and the quality and quantity of eggs will decrease. This means that the success rate of IVF for women over 40 years old is low. According to medical research data, the success rate of IVF for women under 40 years old is about 40%, while that for women over 40 years old is reduced to about 20%.
In addition, age also has an impact on embryo quality. As women grow older, they may increase the probability of chromosomal abnormalities in embryos, thus increasing the risk of miscarriage. Therefore, female age is an important factor affecting the success rate of IVF.
2. Egg quality
Egg quality is one of the key factors affecting the success rate of IVF. As women grow older, the number and quality of their eggs decrease. Low quality eggs tend to lead to difficulties in fertilization, slow embryonic development or chromosome abnormalities. These factors will have a negative impact on the success rate of IVF.
In order to improve the quality of eggs, some hospitals have taken auxiliary measures, such as ovarian stimulation treatment and ovarian pretreatment, to increase the number and quality of eggs. At the same time, the evaluation techniques used to screen the egg quality are also developing, such as oocyte quality assessment and oocyte chromosome screening. The application of these measures and technologies can improve the success rate of IVF.
3. Preparation before pregnancy
Preparation before pregnancy is one of the important factors affecting the success rate of IVF. For women over 40 years old, it is necessary to have a comprehensive physical examination. This includes assessing the female reproductive system, examining ovarian function, endometrial thickness, and uterine morphology. If some problems are found, timely treatment and adjustment can improve the success rate of IVF.
In addition, it is also very important to adjust before preparing for pregnancy. Women should follow a healthy lifestyle, maintain good eating habits, exercise moderately, and avoid bad habits such as smoking and drinking. Men should also take some measures, such as avoiding using computers for a long time and reducing hot baths, to protect the quality of sperm. These preparations can improve the success rate of IVF.
4. Select hospitals and doctors
Choosing appropriate hospitals and doctors is also an important factor affecting the success rate of IVF. High quality hospitals and doctors have rich clinical experience and advanced technical equipment, which can provide better treatment services for patients. At the same time, the reputation and reputation of hospitals and doctors are also important references for selection. Some well-known hospitals have professional teams and rich successful experience in the field of IVF, and the success rate is relatively high.
When selecting hospitals and doctors, patients should also take into account the convenience of transportation, costs and other factors to ensure that they can get good medical services. Choosing appropriate hospitals and doctors can maximize the success rate of IVF.
To sum up, the success rate of IVF at the age of 40 is affected by many factors, such as age, egg quality, preparation before pregnancy, and selection of hospitals and doctors. Understanding these influencing factors and taking corresponding measures and preparations can improve the success rate of IVF at the age of 40.
