Usually, the failure of the fetus to grow or development is mostly related to abnormalities in sex chromosomes in the early pregnancy. Patients with chromosomal abnormalities usually experience miscarriage in the early pregnancy, and such situations are relatively common. If the quality of the egg cells or the sperm is not good enough, the test tube embryos produced will have incomplete sperm-egg fusion development, resulting in the fetus not growing and developing. Heart beats can be seen through B-ultrasound in the early stages of embryonic development, which can be as early as 6-8 weeks (starting from menopause). If no heart beats are detected after 10 weeks, it can be confirmed that the fetus has reached a certain age and the due date has been ruled out. Just like the survival of the fittest among all species in nature, it may be due to problems with the quality of the seeds themselves that prevent them from growing successfully. Because the test tube embryo needs three key female hormones in its early growth and development, namely estrogen, estrogen, and human chorionic gonadotropin, if the pregnant mother's own endogenous hormone is insufficient, it will lead to the arrest of the test tube embryo. The test tube embryo has stopped growing and naturally has no fetal heartbeat. If the pregnant woman herself has certain antigens, it will inhibit the growth and development of the test tube embryo, and thus cause the death of the test tube embryo. Furthermore, some couples have had miscarriages for several times but could not find the cause, and have been treating it as a woman's problem. It was eventually discovered that there was a problem with the quality of the husband's sperm. A more rare case is that the woman has antigens to her husband's sperm (i.e. antisperm antibodies), which makes it difficult to get pregnant, or she is prone to miscarriage due to rejection of the test tube embryo during pregnancy. If the embryo has been implanted for so many years and there is no fetal heartbeat, it needs to be abandoned. If the test tube embryo has stopped growing and development, and there is no miscarriage due to the influence of estrogen, an abortion should be performed. It is very harmful to the human body if the embryo stays in the body. Did you have bleeding or abdominal pain during pregnancy? If you have bleeding or abdominal pain during pregnancy, you should pay close attention. Bleeding or abdominal pain during pregnancy is undoubtedly abnormal. If this happens, you should see a doctor to find out the cause. |
