Is the success rate of test tube twins related to age

IVF is an assisted reproductive technology, which helps couples who cannot conceive naturally realize their reproductive dreams by cultivating the fertilized eggs to a certain stage and then transplanting them into the mother's body. The twins in IVF refer to twins who were successfully pregnant in the same IVF transplantation. So, is the success rate of test tube twins related to age? This problem will be described in detail from several aspects below.

1. Relationship between age and ovarian function

The influence of female age on the success rate of IVF is mainly related to the quality and quantity of eggs. The ovarian function of women gradually declines after the age of 30, and the quality and quantity of eggs will also decrease. This has led to a lower success rate for older women to produce twins in IVF.

Research shows that the success rate of in vitro embryo implantation is about 30% for women under 25 years of age, while the success rate of women over 35 years of age is only about 10%. With the increase of age, women's fertility will decline, and the chance of having twins will also decrease accordingly.

2. Relationship between age and uterine environment

In addition to the changes in the quality and quantity of eggs, female age also has a certain impact on the uterine environment in IVF. Older women may be accompanied by endometrial degeneration, cervical relaxation and other problems. These factors will affect the implantation and implantation of fertilized eggs, thus reducing the success rate of producing twins.

Older women may need more treatment and longer cycles to provide a more suitable uterine environment for embryonic development. Therefore, older women have a lower success rate in producing twins during IVF.

3. Relationship between age and embryo quality

The success rate of IVF embryo implantation is also related to age, and the quality of embryos produced by older women may decline. Embryo quality directly affects the implantation and development of embryos, so it also plays an important role in the formation of twins.

Research shows that the quality of embryos produced by older women is poor. Relatively speaking, the probability of abnormal embryonic development or malformation will also increase. This further reduces the success rate of older women in producing twins.

4. Relationship between age and physiological status

The growth of age may be accompanied by various chronic diseases and changes in physical functions, such as hypertension, diabetes, etc. These diseases and the decline of physical function may have a negative impact on the success rate of IVF.

Therefore, older women may need more medical intervention and monitoring during IVF to ensure the health of mothers and embryos. This will also indirectly affect the success rate of twins.

Summary

To sum up, the success rate of test tube twins is closely related to age. Older women have a lower success rate in producing twins due to the decline of ovarian function, changes in uterine environment, decline in embryo quality and changes in physiological status. Therefore, when choosing the IVF technology, the couple should take into account the age of the woman and treat her when the age is appropriate, so as to improve the success rate of the IVF twins.
