The incidence of embryonic abortion has been on the rise in recent years and may be related to a variety of factors such as disease, environmental pollution, and radiation. Women who have experienced embryonic abortion are often nervous about getting pregnant again, fearing that embryonic abortion will occur again. So, what do you need to do to prepare for another pregnancy? It is important to find out the cause of the disease so that we can formulate appropriate countermeasures to solve the problem at its root. Therefore, we need to find the causes of the previous embryonic stoppage and make countermeasures accordingly. The main reasons for embryonic abortion are as follows: 1. The embryo itself is the most common problem is the chromosomal abnormality of the embryo in the previous pregnancy, which leads to difficulties in healthy development of the embryo and eventually embryonic abortion and elimination from the market. When the fetal stoppage is cleared, the fetal tissues should be left out and sent for chromosome examination in order to clarify the cause of fetal stoppage. If it is indeed caused by chromosomal abnormalities in the embryo, the possible causes of chromosomal abnormalities in the embryo are: chromosomal abnormalities in the male/female partner, resulting in chromosomal abnormalities in the sperm or egg and eventually the formation of an abnormal embryo; chromosomal normalities in the male/female partner, with abnormal sperm or egg formed by toxic and harmful substances or radiation and other factors during the formation process, eventually resulting in the formation of an abnormal embryo. If it is caused by chromosomal abnormalities in one or both sexes, then further consultation with a geneticist is needed to understand the probability of the next embryonic abortion and treatment measures; if both sexes have normal chromosomes, abnormal embryonic chromosomes are often incidental events, and both partners should avoid exposure to toxic and harmful substances, drugs that affect germ cells, radiation, smoking and alcohol cessation before getting pregnant again. 2. Male partner problems The common ones are chromosomal abnormalities in the male partner and sperm abnormalities in the male partner (high malformation rate, carrying abnormal chromosomal DNA, etc.). The former requires further consultation with a geneticist, while the latter requires further search for the causes of sperm abnormalities and corresponding treatment to improve sperm quality. 3. Female partner problems Commonly, there are chromosomal abnormalities in the female partner, egg abnormalities (such as multiple sperm fertilization due to abnormal egg structure, eggs carrying abnormal chromosomes, etc.), immune factors, abnormal blood clotting function, infection with pathogenic bacteria or viruses harmful to the embryo, severe systemic infections, endocrine abnormalities and other factors. These factors can lead to embryonic abortion, especially for those who have had two or more embryonic abortions, a more comprehensive examination should be done before getting pregnant again, and the corresponding treatment should be carried out. In addition to the above-mentioned factors, there are some people with unknown causes of embryonic abortion, but unknown causes are not without causes, probably due to the current scientific and technological limitations, it is impossible to identify the causes of embryonic abortion. To sum up, women who are preparing for pregnancy after embryonic stoppage should first consult a professional doctor to find the causes of embryonic stoppage, exclude infection, chromosomal abnormalities, immune abnormalities, blood clotting abnormalities, sperm abnormalities and many other factors, and make appropriate treatment according to the causes.
