Is the age of the third generation IVF related to the success rate?
Three generation IVF is an important breakthrough in assisted reproductive technology in recent years, which has realized the dream of becoming parents for many infertile couples. However, with the growth of age, female reproductive capacity will gradually decline. So, is there a relationship between the age of three generations of IVF infants and the success rate? The following will be discussed from different perspectives.
Aspect 1: The influence of female age on the success rate
Women's ovarian function peaked at puberty and then gradually declined. Therefore, female age is one of the important factors that affect the success rate of three generations of IVF. The study found that after the age of 35, the success rate of IVF gradually declined. This may be due to the weakening of ovarian function, the decline of egg quality and the instability of hormone levels.
In addition, female age also affects the success rate of embryo implantation and pregnancy. With the increase of age, endometrial thinning, blood flow reduction and other factors will weaken the ability of embryo implantation in the uterus, thus reducing the success rate of pregnancy.
Therefore, if couples hope to achieve a higher success rate through the third-generation IVF technology, women should be treated as soon as possible to improve the quality of eggs and the adaptability of the intrauterine environment.
Aspect 2: The influence of male age on the success rate
Although the female age has a greater impact on the success rate of the third generation of IVF, the male age should not be ignored. As men grow older, their sperm quality and quantity will decrease, thus affecting fertilization and embryonic development. In addition, older men may also carry some genetic defects or gene mutations, increasing the risk of genetic diseases.
Therefore, when couples conduct the third generation IVF technology, men should also receive comprehensive sperm assessment and genetic counseling to ensure the healthy development of embryos and reduce the risk of genetic diseases.
Aspect 3: Comparison of success rates in different age groups
The research shows that the success rate of three generations of IVF has obvious differences in different age groups. Generally speaking, the success rate of three generations of IVF for women before the age of 35 is higher, but it gradually decreases after the age of 35. Specifically:
1. Among women under 30 years old, the success rate is usually about 40% to 50%.
2. Among women aged 35 to 39, the success rate is usually about 25% to 35%.
3. Among women over 40, the success rate is usually about 10% to 15%.
Therefore, as women grow older, the success rate will gradually decrease. This also explains why many hospitals recommend that women under the age of 30 should receive three generations of IVF treatment as soon as possible.
Aspect 4: Progress of medical technology and improvement of success rate
With the continuous progress of medical technology, the success rate of third-generation IVF is also rising. In the past, the success rate of three generations of IVF was very low, but with the continuous improvement of IVF technology, embryo culture environment, embryo screening and other aspects, the success rate was rising.
In China, some authoritative hospitals such as Peking Union Medical College Hospital and Shanghai Jiaotong University Children's Hospital have made important breakthroughs and fruitful achievements in the field of third-generation IVF. They have adopted a series of advanced assisted reproductive technologies to realize the birth dream for infertile couples.
Summary
In conclusion, the success rate of three generations of IVF is closely related to age. Both women's age and men's age will have an impact on the success rate, especially the significant decline of women's age after 35 years old. There are also significant differences in the success rate of different age groups. The older the age, the lower the success rate. However, with the progress of medical technology, the success rate of third-generation IVF has significantly improved, which has realized the birth dream for more infertile couples.
