Correlation between success rate of IVF and female age
IVF is a kind of assisted reproductive technology, which helps those families who are difficult to conceive naturally realize their reproductive dreams by artificially placing the fertilized eggs into women's bodies. However, there is a close relationship between the success rate of IVF and women's age. The following will discuss the influence of female age on the success rate of IVF from four aspects: physical condition, egg quality, ovarian reserve and hormone level.
Physical condition
The growth of women's age will lead to gradual changes in their physical conditions, which will have an impact on the success rate of IVF. Young women are in a state of full physical function, good endometrium, normal ovarian function, and easy to conceive. As women grow older, their physical conditions gradually decline, for example, the endometrium may become thinner, the ovarian function may decline, and they may suffer from some gynecological diseases, such as hysteromyoma. These factors will reduce the success rate of IVF.
In addition, older women are also prone to chronic diseases such as hypertension and diabetes, which may adversely affect the health of embryos and the process of pregnancy. Therefore, women should maintain a good physical condition, which helps to improve the success rate of IVF.
Egg mass
Female age has a direct impact on the quality of eggs. Eggs are one of the key factors for the success of IVF. The eggs of young women are of good quality, contain fewer chromosomal abnormalities, and can be easily fertilized and developed into healthy embryos. However, with the increase of age, the quality of eggs decreases, and the incidence of chromosomal abnormalities increases, leading to an increased risk of abnormal embryonic development.
In order to improve the quality of eggs, some IVF hospitals have adopted PGS (Embryo Chromosome Screening) technology, which can screen embryos with high risks of chromosomal abnormalities and genetic diseases, so as to avoid embryo transfer with chromosomal abnormalities and improve the success rate of IVF.
Ovarian reserve
The monthly ovulation process of women is a process of consuming eggs. With the increase of age, women's ovarian reserves are gradually decreasing. Ovarian reserve refers to the number and quality of eggs in the follicle, and the number of eggs restricts the possibility of IVF success.
For young women, the ovarian reserve is relatively sufficient, which can provide more eggs, which increases the probability of success of IVF. Older women may face the problem of weakened ovarian function and decreased egg quality, which leads to insufficient ovarian reserve and reduced success rate of IVF.
Hormone levels
The growth of female age will lead to changes in the endocrine system and hormone levels, which will affect the success rate of IVF.
For example, the level of estrogen in women's ovaries will decline with age, which may lead to the difficulty of implantation of fertilized eggs in the endometrium after IVF. In addition, the level of gonadotropin secretion in the ovary will also decline with age, which may lead to ovarian dysfunction, affecting follicle growth and egg quality.
Therefore, if women's hormone levels are unbalanced, the success rate of IVF may be reduced. Before implementing IVF, doctors usually adjust female hormone level through hormone examination and hormone replacement therapy to improve the success rate of IVF.
Summary
There is a close relationship between the success rate of IVF and women's age. Young women have a higher success rate due to their relative advantages in physical condition, egg quality, ovarian reserve and hormone level. With the growth of age, the adverse changes of these factors will lead to the decline of the success rate of IVF. Therefore, for older women, we should seek the advice and help of professional hospitals to develop appropriate assisted reproduction programs and improve the success rate of IVF.
