In Vitro Evidences of Heparin’s Effects on Embryo Implantation and Trophoblast Development

Heparin seems to be effective in ameliorating pregnancy outcome in thrombophilic women with previous recurrent pregnancy loss, preeclampsia, intrauterine growth restriction and sudden fetal death. A prophylactic effect of heparin treatment has also been proposed in terms of prevention of adverse pregnancy outcomes recurrence in women with history of recurrent miscarriage, severe preeclampsia, placental abruption, low neonatal birth weight and intrauterine fetal death not related to thrombophilia, although literature in this field is quite controversial.
