Causes of IVF abortion
IVF abortion refers to the failure of IVF embryo transfer to develop successfully and eventually lead to abortion. There are many reasons for IVF abortion. The following four aspects will be discussed in detail, including embryo quality, uterine environment, hormone level and maternal factors.
Embryo quality
Embryo quality is one of the important factors affecting IVF abortion. In the process of IVF and culture, the quality of IVF embryos may have problems, such as chromosome abnormalities, gene mutations, etc. These problems may lead to the natural elimination of embryos, thus triggering IVF abortion. In addition, the development process of the embryo may also be affected. If the development is slow or abnormal, it is also easy to cause abortion.
In addition, the further development and implantation of embryos after implantation are also important. If the embryo is not successfully implanted, it will miscarry at an early stage. This may be related to endometrial quality, congestion and other factors.
In order to avoid embryo quality problems, the hospital will carry out embryo quality assessment in the process of IVF, and select high-quality embryos for implantation.
Uterine environment
The uterine environment is one of the key factors for the successful implantation and development of IVF. The quality, thickness and blood supply of endometrium will affect the implantation and development of IVF. If the quality of endometrium is poor, such as hyperemia, atrophy or pathological changes, it will lead to the failure of normal implantation of embryos, which will lead to abortion.
In addition, the endometrium also needs to provide sufficient nutrients and an environment to support embryonic development. If the blood supply of the endometrium is insufficient, the embryo cannot get enough nutrients, which may also lead to abortion.
The hospital improves the suitability of the uterine environment to increase the success rate of IVF by detecting the endometrium of patients and recuperating if necessary.
Hormone levels
Hormones play an important role in regulating the development and implantation of IVF. Abnormal hormone levels may increase the risk of IVF abortion.
First, progesterone is an important hormone to maintain pregnancy. Inadequate secretion or abnormal function of progesterone will lead to endometrial instability, affecting embryo implantation and pregnancy maintenance. Secondly, the imbalance between estrogen and progesterone may also affect the development of IVF. Too high or too low hormone levels may lead to abnormal embryonic development or abortion.
The hospital will monitor and regulate the hormone level in the IVF cycle according to the specific conditions of patients, so as to improve the success rate of IVF and reduce the risk of abortion.
maternal factors
Maternal health and lifestyle will also affect IVF abortion.
First, maternal age is one of the important factors affecting IVF abortion. With the increase of age, women's reproductive capacity gradually decreases, so older women have a higher abortion rate for IVF.
Secondly, the maternal physical condition and lifestyle will also affect the development and abortion of IVF. For example, suffering from some chronic diseases, being underweight or overweight, smoking and drinking will increase the risk of miscarriage.
Therefore, before IVF, the hospital will conduct a comprehensive physical examination for patients, and give corresponding guidance and intervention to improve the success rate of IVF.
Summary
There are many reasons for IVF abortion, among which embryo quality problems, poor uterine environment, abnormal hormone levels and maternal factors are important influencing factors. In the process of IVF, the hospital will comprehensively detect and adjust these factors to increase the success rate of IVF and reduce the incidence of abortion. Under the guidance of doctors, patients should actively cooperate and make relevant preparations and adjustments to improve the success rate of IVF.
