Whether the success rate of IVF will decline with age
IVF is an assisted reproductive technology, which helps couples who cannot conceive naturally realize their reproductive dreams by cultivating fertilized eggs in the laboratory and then transplanting healthy embryos into the mother's womb. However, whether the success rate of IVF will decline with age has always been a concern.
Age and decline of ovarian function
The age of women is one of the important factors that affect the success rate of IVF. The number and quality of eggs in women's ovaries will decline with age. The decrease of egg quality may lead to chromosomal abnormalities and increase the risk of embryo implantation failure and abortion. In addition, aging may also be accompanied by an increased risk of disease, such as endometriosis, polycystic ovary syndrome, etc. These diseases will also have a negative impact on the success rate of IVF.
According to the data of the American Association of Reproductive Medicine, the success rate of IVF for women under 35 years old is about 40%, while with the growth of age, the success rate of women over 40 years old will decline significantly, and there is almost no success rate for women over 50 years old. Therefore, age is an important factor affecting the success rate of IVF.
Influence of male factors
The success rate of IVF is not only related to female factors, but also male factors. With the increase of age, the quality and quantity of male sperm will also decline. The decline of sperm quality may lead to the obstruction of embryo development, which may affect the success of embryo implantation and development. In addition, aging also increases the risk of male infertility, such as sperm DNA fragmentation and chromosome abnormalities.
Therefore, before IVF, both the husband and wife need to carry out comprehensive fertility tests, including semen analysis and female age related tests, to assess the success rate of IVF and formulate the best treatment plan.
Advances in medical technology
Although age is an important factor affecting the success rate of IVF, the progress of medical technology has also made up for the influence of age on the success rate to a certain extent. With the continuous development of assisted reproductive technology, the success rate of IVF has been improved to a certain extent.
Nowadays, more and more clinical practices have proved that the success rate of IVF can be improved and the risk of embryo implantation failure and abortion can be reduced through new technologies such as blastocyst culture, embryo detection and selective embryo transfer. In addition, the use of frozen embryo technology can make the success rate of infants not limited by the age of women.
summary
In conclusion, it is an objective phenomenon that the success rate of IVF decreases with age. The growth of female age will lead to the decline of ovarian function, affecting the quality of eggs and the success rate of embryonic development. At the same time, male factors will also affect the success rate of IVF. However, advances in medical technology also provide opportunities for older couples. Before IVF, couples need to carry out a comprehensive birth inspection and choose appropriate technical means to improve the success rate of IVF.
