What is the difference between the success rate of IVF and the gestational age in the United States?
In vitro fertilization (IVF) is a method to promote fertility by fertilizing sperm and eggs in vitro and then implanting the fertilized eggs into the mother. In the United States, with the development of technology and people's recognition of reproductive medicine, IVF has become an increasingly popular choice. However, for women of different gestational ages, the success rate of IVF will be different. This article will discuss in detail the difference between the success rate of IVF and the gestational age in the United States.
1. The influence of age on the success rate of IVF
The success rate of IVF is closely related to the age of women. If 35 years old is taken as the limit, women younger than 35 years old have relatively good egg quality and are more likely to succeed in IVF. According to the data of the Centers for Disease Control and Prevention (CDC) in the United States, in the IVF cycle implemented in 2018, the success rate of female IVF infants younger than 35 years old was about 40% to 45%.
However, with the growth of age, the quality of female eggs gradually declines, and the success rate of IVF will also decrease accordingly. For women aged between 35 and 37, the success rate of IVF dropped to 30% to 35%. For women over 40, the success rate is only 10% to 15%. This is because the number and quality of female eggs will decline with age, and the quality of gametes is one of the important factors for the success of IVF.
It is worth mentioning that the above data are only for reference, and the actual success rate is also affected by many factors, such as individual differences, male reproductive capacity, etc.
2. The influence of age on the number of cycles required for IVF success
Another important factor related to age is the number of cycles required for IVF success. Even if the success rate is the same, older women often need more cycles to successfully conceive. This is because the egg quality has declined, and more attempts may be needed to obtain a healthy embryo.
According to the American Infertility Association (ASRM), women aged 30 to 34 need an average of 2 to 3 cycles to successfully conceive. For women aged 35 to 37, it takes an average of 3 to 4 cycles. For women over 40 years old, more cycles may be needed, with an average of more than 6 cycles.
3. The influence of age on the risk of complications in IVF
There may be some complications during IVF, such as multiple pregnancy and early abortion. The risk of these complications is also related to women's age.
For women under 35 years old, the risk of multiple pregnancy is relatively low, ranging from 10% to 15%. However, the risk of multiple pregnancy increases with age. The risk of multiple pregnancy for women aged 35 to 37 years is about 15% to 20%. For women over 40 years old, the risk of multiple pregnancy can exceed 30%.
In addition, older women also have an increased risk of early abortion during IVF. According to the data of American College of Obstetrics and Gynecology (ACOG), the risk of early abortion for women aged 35-39 is about 25-30%. Women over 40 years old have a higher risk of early abortion, which can reach more than 40%.
4. Methods to increase success rate
Although age has some influence on the success rate of IVF, there are still some ways to increase the chance of success. First, women can consult in advance to understand their fertility potential and feasible solutions. Secondly, before receiving IVF, women can improve their living habits by balancing nutrition, reducing alcohol and tobacco intake, and avoiding overwork.
In addition, selecting appropriate hospitals and doctors is also the key to improve the success rate. There are many well-known and professional reproductive medicine centers in the United States, such as Institute for Reproductive Health of the University of Maryland School of Medicine and Center for Human Reproduction of New York Presbyterian Hospital. These hospitals provide high-quality IVF services and can provide more comprehensive assisted reproductive technology and professional medical teams.
summary
In conclusion, age has a significant impact on the success rate of IVF in the United States. Older women with IVF have a lower success rate and may need more cycles and face a higher risk of complications. However, through early consultation, improving living habits and choosing professional hospitals and doctors, the success rate can be improved. When facing the choice of test tube babies, women should fully understand their fertility potential and have in-depth discussions and planning with professional doctors.
