Summary

The use of low dose aspirin is recommended for high risk patients to reduce the risk of pre-eclampsia, placental abruption and antepartum hemorrhage. Recent studies have shown that in a specific population, the use of low dose aspirin might reduce the risk of preterm birth in pregnant women with singleton pregnancy. In June 2022, clinique ovo started implementing the use of Aspirin 162 mg instead of 81 mg in the frozen embryo transfer cycles based on recent study outcomes. The use of Aspirin 162 mg might have additional benefits on the embryo transfer outcomes by decreasing the miscarriage. Moreover this can be continued until late in pregnancy without adverse effects.
