The relationship between the success rate of IVF and age
Test tube baby technology is a modern technology, which can help those couples who are naturally difficult to conceive realize their desire to have children. However, there is a relationship between the success rate of IVF and age. This article will elaborate from four aspects: the influence of age on egg quality, the decline of ovulation function, the suitability of uterine environment and the body metabolism.
1. Influence of age on egg quality
The female reproductive system will gradually age with age, and the egg quality will also decline. With the increase of female age, the number and quality of eggs decrease, increasing the risk of IVF failure. Most women in the age before 30 years old have relatively good egg quality and high success rate. However, with the growth of women's age, especially those over 35 years old, the decline of egg quality will accelerate, and the success rate of IVF will be significantly reduced.
The relationship between age and egg quality is based on a large number of clinical studies. For example, data from a hospital in a country shows that the success rate of IVF for women under 30 years old is between 50% and 60%, while that for women over 40 years old is only 20% to 30%.
Therefore, the age of women is an important factor affecting the success rate of IVF.
2. The decline of ovulation function
The ovulation function of women will decline with age. The weakening of ovulation function will reduce the number of eggs produced by the ovary, thereby reducing the success rate of IVF. Older women may need drugs to stimulate ovarian ovulation for IVF technology due to the decline of ovulation function, while younger women can ovulate naturally more easily.
The decline of ovulation function will also cause the imbalance of hormone levels, further affecting the growth and preparation of endometrium. This may lead to inappropriate uterine environment, thus affecting the implantation and development of IVF.
Therefore, the decline of ovulation function is another important factor affecting the success rate of IVF.
3. Suitability of uterine environment
The suitability of the uterine environment is critical to the success of IVF. The endometrium of older women may become thinner due to the reduction of nutrition supply and blood circulation of endometrium, which may affect the implantation of fertilized eggs. In addition, insufficient blood supply to the endometrium will also reduce the success rate of IVF.
A study shows that the suitability of the uterine environment for women over 35 years old in a hospital in a country is related to age. The data from the hospital shows that the suitability rate of the uterine environment for women under 30 years old is 50% to 60%, while that for women over 40 years old is only 20% to 30%.
Therefore, the suitability of the uterine environment is another important factor affecting the success rate of IVF.
4. Body metabolism
The increase of age is also related to the change of body metabolism. The slowing down of metabolism may lead to the disorder of fat and sugar metabolism in the body, and these factors will have a negative impact on the success rate of IVF.
Some studies have shown that diet and exercise habits have a certain impact on body metabolism and the success rate of IVF. For example, a large number of studies have shown that obese women have a lower success rate in IVF technology. In addition, diseases such as diabetes and thyroid dysfunction will also reduce the possibility of IVF success.
Therefore, body metabolism is another important factor affecting the success rate of IVF.
Summary
The success rate of IVF is closely related to age. The increase of age will lead to the decline of egg quality, the decline of ovulation function, the unsuitable uterine environment and the change of body metabolism, which will reduce the success rate of IVF. Therefore, age is an important consideration for couples who want to use IVF technology. Early planning and implementation of IVF technology can improve the success rate, especially for older women.
