Is the success rate of IVF affected by age?
IVF is a kind of assisted reproduction technology, which artificially inserts the fertilized egg into the female uterus, helping couples who cannot conceive naturally realize their reproductive dreams. However, whether the success rate of IVF will be affected by age is a matter of great concern. In the following article, we will discuss this problem from many aspects.
Age related ovarian function
Female age is an important factor in determining the success rate of IVF. With the growth of women's age, the ovarian function gradually declined. The quality and quantity of eggs of young women are higher, but with age, the ovarian function will gradually decline, and the quality of eggs will decline. This will affect the fertilization rate of eggs and the implantation rate of embryos.
For example, a study found that the success rate of IVF for women under 35 years old was higher, and the success rate gradually declined with age. The success rate of women over 40 years old is significantly reduced, even reaching below 20%. This is because the reduction of ovarian function leads to the decline of egg quality, which reduces the success rate of fertilization and implantation.
In addition, the number of female eggs also decreases with age, which will also affect the success rate of IVF. The decrease in the number of eggs will affect the chances of fertilization and implantation, so young women are generally more likely to succeed in pregnancy than older women.
Age related uterine environment
In addition to changes in ovarian function, the female uterine environment will also be affected by age, thus affecting the success rate of IVF. The quality and thickness of endometrium may decrease with age, which will reduce the chances of embryo implantation.
A study shows that women aged 40 years and above have thin endometrial thickness, which leads to a decline in the success rate of embryo implantation. For women under 30 years old, the endometrial thickness is usually better, and the success rate of embryo implantation is higher.
Therefore, in addition to the influence of ovarian function, the change of uterine environment also has a certain impact on the success rate of IVF.
Cases of related hospitals
London IVF Center is one of the famous IVF hospitals in Britain. According to the statistics of the center, the success rate of IVF for women of different ages is different. Among women under 35, the success rate is about 40% to 50%; Among women aged 35 to 39, the success rate dropped to 30% to 40%; The success rate of women over 40 years old is only 20-30%.
In addition, the center also pointed out that the ideal age for women to choose IVF is under 35 years old, because the success rate of IVF for women in this age group is relatively high.
Summary
It can be seen from the above aspects that the success rate of IVF will be affected by age. Young women have better ovarian function and uterine environment, and higher number and quality of eggs, so they have a greater chance of successful pregnancy. With the increase of age, the ovarian function decreases, the uterine environment changes, and the success rate of IVF gradually decreases.
Therefore, it is very important for couples who plan to carry out IVF to choose the appropriate age for treatment. Young women usually have a higher success rate, while older women have a lower success rate. However, the development of modern medicine provides more hope for older women. Doctors can formulate the most appropriate treatment plan according to the situation of each individual to improve the success rate of IVF.
