Why IVF has been unsuccessful
Test tube baby, namely artificial insemination in assisted reproductive technology, is a way to help couples who cannot conceive naturally to achieve their reproductive aspirations. However, although this technology has made considerable breakthroughs and progress, there are still many cases where IVF is not successful. This article will discuss the reasons why IVF has not been successful from many aspects.
1. Physiological problems
The success rate of IVF depends largely on the physiological conditions of both spouses. First of all, female eggs must be able to fertilize and develop normally, otherwise IVF cannot succeed. Some women may have impaired ovarian function and may not be able to produce enough healthy eggs. In addition, the thickness and activity of endometrium also play an important role in the success of IVF. If the endometrium cannot provide a suitable environment for the implantation of fertilized eggs, IVF is also difficult to succeed.
In addition, male reproductive health is also one of the key factors for the success of IVF. The quality and quantity of male sperm will directly affect the success rate of fertilization. If men have abnormal sperm or insufficient sperm, IVF may fail.
2. Age factor
The age of women is also an important factor in the success of IVF. As women grow older, their egg quality will decline, and they are more vulnerable to chromosomal abnormalities. According to medical research, the success rate of women who try IVF after the age of 35 will be significantly reduced. In addition, the number of female eggs will gradually decrease with age, which means that the chances of fertilization will become more limited.
For men, age will also have a certain impact on the success of IVF. With the growth of age, the quality and quantity of male sperm will also decline, thus reducing the success rate of fertilization.
3. Diseases and genetic factors
Some diseases and genetic factors may also lead to the failure of IVF. For example, women with uterine fibroids, oviduct obstruction, polycystic ovary syndrome and other diseases often lead to the failure of IVF. In addition, some couples may have the risk of genetic diseases. They may choose to have IVF and genetic screening to avoid passing on genetic diseases to their children. However, genetic screening is not always able to completely avoid the influence of genetic factors.
4. Psychological pressure and emotional factors
The process of IVF is often accompanied by long-term treatment and high psychological pressure, which may also become a factor that makes IVF difficult to succeed. The emotional state and mental health of both spouses are very important to the success of IVF. Long term treatment and failed attempts may lead to depression, anxiety and stress in both husband and wife. These negative emotions will have a negative impact on the success of IVF.
Summary
The reasons for the failure of IVF can be attributed to physiological problems, age factors, disease and genetic factors, as well as psychological pressure and emotional factors. These factors interact to influence the success rate of IVF. Although IVF technology has made great progress in science, further research and efforts are needed to improve the success rate. In addition, both husband and wife should also actively face psychological pressure and seek appropriate support and help to increase the possibility of IVF success.
