The relationship between the success of in nest IVF and age
In nest test tube baby is an assisted reproductive technology that combines sperm and eggs in the laboratory and cultivates them into embryos, and then re implant the embryos into the mother's uterus. Over time, scientists and doctors have made continuous research on the success rate of IVF in the nest and found that age is a key factor affecting the success rate of IVF. This article will elaborate on the relationship between the success of IVF and age from four aspects: the impact of age on women's egg quality, the incidence of pregnancy and childbirth, the rate of abortion and the success rate.
Effect of age on egg quality
Women's age has a significant impact on egg quality. With the increase of age, the number and quality of women's eggs gradually decrease. In order to improve the success rate of in nest test tube babies, doctors generally recommend older women to donate eggs and use the eggs of young women with better egg quality. In fact, studies have shown that the success rate of using young women's eggs for in nest IVF is significantly higher than that of using older women's eggs.
In addition, young women's eggs are more likely to be successfully fertilized and develop into healthy embryos. In contrast, the quality of older women's eggs declines, and they are vulnerable to problems such as gene mutation, which leads to the failure of embryo implantation or an increase in the birth rate of abnormal fetuses.
The influence of age on the incidence of pregnancy and childbirth
The success rate of IVF in the nest is also closely related to the incidence of pregnancy and childbirth in women. With the increase of age, the incidence of pregnancy and childbirth of women gradually decreases, because young women have stronger fertility potential and are more likely to become pregnant. According to data statistics, women under 35 years old have a higher success rate of in nest IVF, while women over 40 years old face greater difficulties in pregnancy and childbirth.
Young women who carry out IVF in the nest can be more easily pregnant and deliver successfully, because they are in good health and their physiological environment is more suitable for the growth of embryos. However, older women may suffer from poor intrauterine environment due to the decline of their physical status, which may adversely affect the implantation of fertilized eggs and fetal development.
Influence of age on abortion rate
Age also affects the abortion rate of IVF in the nest. The study found that young women had a lower abortion rate when carrying out in nest IVF, while older women faced a higher risk of abortion. This is mainly because the quality of young women's eggs is good, the development of fertilized eggs is healthy, and the survival rate of embryos after implantation into the uterus is relatively high. On the contrary, the egg quality of older women decreases, and the survival rate of embryos after implantation is lower, which increases the possibility of abortion.
Summary
The success of IVF in nest is significantly related to age. The quality of young women's eggs is good, the incidence of pregnancy and childbirth is high, and the abortion rate is low, so the success rate of in nest IVF is relatively high; Older women face challenges such as decreased egg quality, difficulties in pregnancy and childbirth, and increased risk of miscarriage. These results emphasize the importance of age in IVF in the nest. For older women, it is crucial to select appropriate hospitals as early as possible for IVF in the nest surgery to improve the success rate.
