The relationship between pregnancy rate and age of IVF
IVF technology is a kind of assisted reproduction technology. The fertilized egg is cultivated to a certain stage through artificial fertilization, and then the embryo is transferred to the mother's uterus to achieve pregnancy and delivery. However, the pregnancy rate of IVF is closely related to the age of women. At different ages, women's physiological conditions and egg quality are different, which affects the possibility of IVF.
1. The pregnancy rate of young women is high
The relatively high pregnancy rate of young women is due to their relatively good egg quality. Women have all their eggs at birth, and the number and quality of eggs will gradually decrease with age. When young, the chromosome structure of the egg is relatively sound, and the formation and development of the fertilized egg is more smooth. At the same time, the endometrium of young women is more suitable for the implantation of fertilized eggs.
In assisted reproductive technology, young women have a higher success rate in using IVF technology. According to the statistics of a well-known reproductive hospital in China, the IVF rate of women under 30 years old can reach more than 50%, while the success rate of women over 40 years old is only about 10%.
2. Effect of age on ovarian reserve
The influence of age on female ovarian reserve is one of the main reasons for the decline of IVF success rate. Women's ovarian reserve is one of the important indicators to measure their fertility. As women grow older, their ovarian reserves gradually decrease, and the number and quality of follicles will decline. This will reduce the chances of IVF, and even may not be able to obtain enough healthy eggs.
Some medical institutions assess women's ovarian reserve by measuring the levels of ovarian reserve hormones, gonadotropin (FSH) and inhibin (BMI). These indicators can help doctors determine the best time and treatment plan for IVF, and increase the possibility of successful pregnancy.
3. Influence of age on egg quality
As women grow older, their egg quality will also be affected. Egg quality not only affects the formation and development of fertilized eggs, but also affects the implantation of embryos and the stability of pregnancy.
The effect of aging on egg quality is mainly manifested in the increase of chromosome abnormalities, especially chromosome number and structure abnormalities. These chromosomal abnormalities will increase the risk of embryo development failure and abortion. Therefore, young women usually have a higher pregnancy success rate in IVF treatment, and are also more likely to obtain healthy embryos.
4. Influence of age on uterine environment
The adaptability of female uterine environment is also crucial to the success of IVF. With the increase of age, the thickness of endometrium and nutrition supply will be affected, thus reducing the implantation rate of embryos.
In addition, age is also related to the incidence of habitual abortion. The risk of miscarriage increases with age. This may be related to the change of intrauterine environment and the decline of embryo quality.
summary
In conclusion, the pregnancy rate of IVF is closely related to age. The pregnancy rate of young women is higher because their egg quality and ovarian reserve are relatively good. With the growth of age, the egg quality and ovarian reserve gradually decline, leading to reduced chances of IVF. In addition, the influence of age on egg quality and uterine environment is also one of the factors that reduce the success rate of IVF. Therefore, age is an important consideration for women who wish to conceive through IVF technology. Early consultation and treatment can maximize the possibility of successful pregnancy.
