The reduction procedure is relatively less painful. Pregnant women can be reduced vaginally up to eight weeks of pregnancy, and usually one or more reductions can be chosen when multiple fetuses are found during IVF. When a pregnancy beyond eight weeks requires reduction, it is performed via the abdomen depending on the gestational age and fetal placenta, and can be performed by medication or radiofrequency ablation. After the operation, rest in bed, pay attention to vulva hygiene and any abdominal pain and vaginal bleeding, inform the doctor in time if there is any discomfort, and take anti-inflammatory drugs as prescribed by the doctor. In terms of diet, avoid eating raw, cold and stimulating food, and consume more high-quality protein, such as lean meat or fish, milk, etc. Maintain emotional stability and avoid excessive emotional fluctuations. Review regularly at the hospital to detect the development of the fetus.
