In vitro twins can be aborted. IVF twins can be aborted. Twin pregnancies can lead to an increased incidence of maternal and fetal complications, but they also need to be aborted only under special circumstances. Twin pregnancies can lead to an increased incidence of complications for the mother such as gestational hypertension, eclampsia, gestational diabetes, weak contractions, as well as preterm labor, fetal growth restriction, and twin-to-twin transfusion syndrome. Generally, fetal reduction surgery can be performed in the presence of a scarred uterus, the presence of an abnormality in one of the twin fetuses, maternal co-morbidities such as hyperthyroidism, overly short pregnancies, and suspected cervical insufficiency. If IVF twins want to reduce the pregnancy, it should be done under the doctor’s advice to ensure the safety of mother and fetus.
