1. The influence of age on the success rate of IVF
IVF technology provides an option for older couples to prepare for pregnancy, but age does have an impact on the success rate of IVF. First of all, the age of women is the key factor. When young, the quality of eggs is good, and the probability of pregnancy is also high. With the growth of age, the ovarian function gradually declines, and the quality of eggs declines, leading to difficult pregnancy. According to the statistics of a famous hospital in Anqing City, the success rate of IVF for women under 35 years old is as high as 60%, while that for women over 35 years old has declined significantly.
Secondly, the age of men will also affect the success rate of IVF. With the growth of age, the quality and quantity of male sperm will decline, causing difficulty in pregnancy. The research results of a hospital showed that the incidence of sexual dysfunction such as premature ejaculation and impotence also increased significantly for men over 40 years old, which affected the success rate of IVF.
In addition, the common age of couples also has a certain impact on the success rate of IVF. Doctors believe that the age difference between couples is too large, which may affect the cooperation between couples and increase the difficulty of pregnancy. Couples with appropriate age differences can better adapt to the discomfort and pressure during IVF, which has a positive impact on the success rate.
2. Influence of age on endometrial preparation
Endometrial preparation is one of the primary conditions for the success of IVF, and age has a certain impact on endometrial preparation. The abnormal hyperplasia and atrophy of endometrium that may occur in older women will adversely affect embryo implantation. According to the data from a professional reproduction center in Anqing, women over 30 years old have relatively thin endometrium, which may lead to a relatively long preparation period and a relatively low success rate.
In addition, women's aging may also lead to the occurrence of uterine fibroids, polyps and other diseases, further affecting the preparation of endometrium. These uterine lesions will affect the implantation of embryos on the endometrium, thus reducing the success rate of IVF.
Therefore, before IVF, older women should have a uterine examination in advance. If uterine lesions are found, they should be treated in time to improve the success rate of endometrial preparation.
3. Influence of age on embryo quality
Embryo quality is an important factor in the survival rate of IVF, and age also has a certain impact on embryo quality. The growth of female age will lead to the decline of ovarian function and the quality of eggs, which will affect the quality of embryos.
The research of a reproductive center found that 80% of the embryos of women under 35 years old were in good shape and development, while only 60% of women over 35 years old. In the case of poor embryo quality, the possibility of implantation and survival is also low.
In addition, the age of men will also have an impact on the quality of embryos. The growth of male age will lead to the decline of sperm quality, thus affecting the quality of embryos. According to the data from a reproduction hospital in Anqing City, the quality of embryos of male couples over 40 years old is relatively poor, so the number of embryos cultured is relatively small.
4. Age restrictions on the application of reproductive medicine technology
Age will also limit the application of some reproductive medicine technologies to the success rate of IVF. Some elderly women may need to use auxiliary technologies during IVF treatment, such as drug assisted fixation technology after embryo transfer, which may be limited by age.
In addition, older women have a relatively high risk of some potential diseases, such as hypertension, diabetes, etc. These chronic diseases may have a negative impact on the success rate of IVF.
Therefore, for older couples, they should receive a comprehensive physical examination before choosing IVF, understand their own physical conditions, and avoid age affecting the application effect of IVF.
Summary
In conclusion, age has a significant impact on the success rate of IVF. The decline of ovarian function and egg quality of older women, the difficulty of endometrial preparation, the decline of embryo quality, and the restrictions on reproductive medicine technology will lead to the decline of the success rate of IVF. Therefore, couples should fully understand the impact of age on IVF before choosing IVF, and make appropriate decisions based on their personal circumstances to improve the success rate of IVF.
