Pregnancy is a happy thing for every woman, because it is the continuation of their love and the hope of the family, so the arrival of every baby is anticipated. However, some pregnant women were found to have no embryo when they went for a check-up after becoming pregnant. What is the reason for this? In fact, this is related to many factors. The germ is a very important link before the formation of the fetus. The period from the third week of pregnancy to the first month of pregnancy is called the germ period. For a normal intrauterine pregnancy, an ultrasound examination can usually show the intrauterine embryo and fetal heart tube pulsation at 6-7 weeks of pregnancy. The size of the embryo is about 0.5-1 cm. If there is still no embryo or fetal heartbeat after seven weeks of pregnancy, the pregnant mother should consider the possibility that the embryo has stopped developing and should go to the hospital to check the condition of the fetus in time. The main reasons for pregnancy without embryo are as follows: 1. Chromosome abnormality. Whether it is sperm or egg, as long as the chromosomes carrying genetic material are abnormal, even if a fertilized egg is formed, the embryo will not develop normally. 2. Contact with toxic substances. Such as chemical substances, inferior decoration materials, etc., will affect the growth and development of the germ. 3. Exposure to radiation or large amounts of electromagnetic radiation. At this time, germ development will also be affected. 4. Taking drugs that affect germ development. 5. Smoking or drinking. Smoking and excessive drinking not only harm women's reproductive ability, but also affect the quality of sperm, causing embryo development to be poor, and ultimately leading to the risk of fetal malformations. 6. The expectant mother is infected with the virus. If an expectant mother is infected with viruses such as rubella and cytomegalovirus, the pathogens will be indirectly transmitted to the fetus, which may cause fetal malformations. 7. The expectant mother suffers from a chronic disease. For example, severe diabetes, hypertension, heart disease, viral hepatitis, etc. 8. Abnormal maternal immune system. After the mother becomes pregnant, the immune system of both mother and child is not compatible, which causes the mother to reject the fetus and lead to miscarriage. |
