Symptoms of IVF transplantation failure

The failure of IVF refers to the failure of pregnancy or abortion after in vitro fertilization and embryo transfer. The failure of IVF may be caused by many factors, including embryo quality, intrauterine environment, etc. This article will elaborate on the failure symptoms of IVF transplantation from four aspects: embryonic development, abnormal physical signs, pregnancy reaction and endometrium.

1. Embryo development

After IVF transplantation, the embryo implantation can be preliminarily judged by HCG detection in blood or urine. If the HCG detection value is lower than the normal pregnancy range and fails to increase significantly in a short period of time, it may mean that the transplanted embryo is not successfully implanted. In addition, B ultrasound is also an important means to evaluate the development of embryos. If the B-ultrasound examination shows no obvious development of the embryo or the embryo stops developing, it may indicate that the IVF transfer fails. In addition, the level of progesterone after transplantation is also an important indicator to observe the development of embryos. If the progesterone level is lower than the normal range or fails to increase significantly in a short period of time, it may mean that there is a problem in embryonic development, leading to the failure of IVF transplantation.

2. Abnormal physical signs

When IVF transplantation fails, some women may have some abnormal signs. For example, vaginal bleeding or the discharge of brown secretion may indicate that the embryo was not successfully implanted or the pregnancy was abnormal. In addition, some women may feel chest pain or breast swelling, which may be caused by changes in hormone levels. However, these symptoms do not necessarily confirm the failure of IVF transplantation, because sometimes it may be caused by normal pregnancy.

3. Pregnancy reaction

After the failure of IVF transplantation, the level of pregnancy hormone in women is usually low. Therefore, some women may have no or only slight pregnancy reaction. Pregnancy reactions include fatigue, nausea, vomiting, breast pain, etc. If there is no or only slight pregnancy reaction in women after IVF transplantation, it may indicate that the transplantation is not successful.

4. Endometrium

The condition of endometrium is very important for the success of IVF transplantation. If the endometrium is too thin or too thick, or there are polyps, endometrial cysts and other abnormalities, IVF transplantation may fail. The condition of endometrium is usually evaluated by B-ultrasound or hysteroscopy. If endometrial abnormalities are found, appropriate treatment or surgical intervention may be required.

summary

The main symptoms of IVF transplantation failure are embryo development, abnormal physical signs, pregnancy reaction and endometrium. The success of IVF transplantation can be preliminarily judged by means of HCG detection, B-ultrasound examination and observation of signs and reactions. However, these symptoms may not absolutely confirm the failure of IVF transplantation, so further examination and judgment are required under the guidance of doctors. The failure of IVF may be caused by many factors, including embryo quality, intrauterine environment, etc. For different symptoms, doctors will take corresponding treatment measures to improve the success rate of IVF transplantation.
