Will the emergency contraceptive pill have an effect on the next generation? Since the drug component of Yutin is mainly progestin, the dose of each tablet is low and excreted quickly, and only 2 tablets need to be taken, it is relatively safe and there is no need to worry about the effect on the fetus, and there is no need to have an abortion for this reason. At present, domestic and foreign experts agree that this emergency contraceptive pill does not have teratogenic effects. Epidemiological investigation has not found any reports of fetal malformation after taking Yuktin contraceptive failure. The chemical composition of yutin is levonorgestrel, and its contraceptive mechanism believes that once conception has been established, there is nothing that can be done by taking yutin. Therefore, emergency contraceptive pills taken during the zero month, i.e., within the menstrual cycle, do not have much effect on the fetus, but if taken after 4 weeks, they may cause malformations in both sexes. This is because the embryo is predominantly cellular and tissue differentiated during the zero month, while the reproductive system develops around the 8th week of gestation. Therefore, from the point of view of eugenics, women who are in good health and young can choose not to have it for the time being after contraceptive failure, while women who are a little older and have difficulty conceiving can have this child. Therefore, the retention of the fetus should be considered in the light of the duration and dosage of the pill – the retention of the fetus is ultimately at the discretion of the pregnant woman and her family according to the actual situation. Intrauterine developmental malformations are determined by a combination of environmental and genetic factors. If you decide to have this child, it is recommended to have regular checkups to rule out malformations by performing 3D ultrasound examination at 20-28 weeks of pregnancy or amniotic fluid chromosome typing examination at about 21 weeks of pregnancy.
