Is the success rate of IVF related to age? Is the success rate of IVF lower with age?
IVF is an assisted reproductive technology. It helps couples who cannot conceive naturally due to infertility and other fertility disorders to realize their reproductive dreams by fertilizing eggs and sperm in vitro, and then implanting the fertilized eggs into women's uterus. However, the success rate of IVF does correlate with age. In general, the older the baby is, the lower the success rate of IVF is. The following will be detailed from four aspects: physical condition, egg quality, uterine environment and treatment response.
1、 Physical condition
Age has an important impact on women's fertility. With the increase of age, women's ovarian function gradually declines. The ovarian function of young women is generally healthy, and it is easier to obtain more eggs in IVF technology, and the egg quality is relatively high. For older women, their ovarian function has begun to decline, and the quality and quantity of follicular development will be affected to some extent, thus reducing the success rate of IVF.
In addition, women's physical condition will also be affected by age. With the growth of age, women's physical functions will gradually weaken, and the possibility of suffering from some chronic diseases will also increase, such as hypertension, diabetes, etc. These chronic diseases will have a certain negative impact on health and the success rate of IVF.
Therefore, the older the baby is, the lower the success rate of IVF is, no matter the ovarian function or physical condition.
2、 Egg mass
Egg quality is one of the key factors affecting the success rate of IVF. The quality of young women's eggs is relatively good, easy to fertilize and develop, thus improving the success rate. However, with the increase of age, the egg quality will decline, and the difference in the egg quality in the follicle will also increase.
High quality eggs are easy to develop into healthy embryos after fertilization, and are successfully implanted in the uterus, eventually forming a test tube baby. However, low quality eggs may lead to fertilization failure, slow embryonic development, implantation failure and other problems, which will affect the success rate of IVF.
Therefore, aging will directly affect the quality of female eggs, thus reducing the success rate of IVF.
3、 Uterine environment
Uterine environment is one of the essential conditions for the success of IVF. The uterus of young women is usually in good condition, and the conditions for embryo implantation are ideal. However, with the increase of age, the thickness and quality of endometrium may decline, which increases the difficulty of embryo implantation.
The change of uterine environment may increase the risk of embryo implantation failure or early abortion, and reduce the success rate of IVF.
Therefore, the older the person is, the changes in the uterine environment may lead to a decline in the success rate of IVF.
4、 Therapeutic response
During IVF, women need to receive a series of hormone treatments to promote follicular development and egg collection. This treatment will have a certain impact on women's physical condition and ovarian function.
Young women usually respond better to hormone therapy, and the success rate of follicle development and egg collection is higher, thus improving the success rate of IVF. For older women, the ovarian function has begun to decline, and the response to treatment is poor. It may require more treatment times to collect enough quantity and quality eggs, thus reducing the success rate of IVF.
summary
In conclusion, there is a certain correlation between the success rate of IVF and age. The older a woman is, the lower her ovarian function and egg quality will gradually decline, and her physical condition and uterine environment will also change. These factors may reduce the success rate of IVF. Therefore, the older the baby is, the lower the success rate of IVF will generally be.
However, the situation of each individual is different. Age is not the only factor that determines the success of IVF. Many other factors also affect the success rate of IVF. Therefore, before IVF, it is recommended that couples should have a comprehensive consultation with doctors, and formulate and adjust treatment plans according to individual conditions.
