Although IVF technology has developed to the present day and is mature, it is not 100% successful and in many cases fails. So what are the main reasons for IVF failure? In fact, the reason for IVF failure may be caused by one or multiple factors. For couples, it is important to identify the reasons and prepare for the next IVF test. Below, we will specifically understand which factors are causing IVF failure.

According to relevant data, in China, the average success rate of in vitro fertilization technology can reach 70%, which is very good. However, for individuals, some may have success rates of 80% or 90%. Below are several reasons for the failure of in vitro fertilization.

1. The body is not ready.

Poor physical condition of women can lead to failure. For example, the female uterus is the growth environment for embryos. If the uterus is not healthy, such as thin endometrium, uterine fibroids, endometrial polyps, hydrosalpinx, etc., these can lead to a decrease in embryo implantation rate. In response to this situation, pregnancy experts will carry out adjuvant treatment techniques based on the woman's physical condition, such as laparoscopic treatment, which can help improve the uterine environment and thereby increase the pregnancy rate of women.

2. The embryo quality is not good.

We know that in vitro fertilization technology, it is necessary to select high-quality embryos for transplantation. However, in practice, we cannot know the quality of the embryos in advance. We can only judge the quality of the embryos on the third day of development, and can only analyze them through embryo fragments. Therefore, for some older couples, their eggs and sperm are inherently of poor quality, Even if some relatively excellent embryos are selected, implantation failure may occur due to chromosomal abnormalities in the embryos.

3. Insufficient psychological preparation.

To be an IVF, both spouses must bear considerable pressure, especially female friends, who not only have to bear physical pressure but also psychological pressure. Many women, in order to achieve success in IVF, constantly give themselves psychological cues, resulting in a heavy psychological burden. Poor psychological conditions can affect endocrine disorders, which can lead to embryo implantation failure. Some women have to undergo transplantation surgery the next day, but the previous day due to psychological pressure, they suffer from insomnia, which affects the success rate.

Through the above reading, we have learned that the reason for the failure of IVF technology may be due to a certain factor, such as poor physical fitness, some reproductive diseases, such as the inability to implant due to thin endometrium, etc., or multiple factors, such as poor quality of the mother's embryo, coupled with thin endometrium and poor mentality, leading to failure. Therefore, for women, it is important to actively face failure and do it multiple times, It can improve the success rate.
