Abstract Maternal thrombophilia (inherited and acquired) has recently been identified as a major cause of thrombembolism, but it may also contribute to adverse pregnancy outcomes and recurrent pregnancy loss. To determine the association of specific inherited thrombophilias and recurrent fetal loss (RFL), three gene mutations (Factor V Leiden, prothrombin G20210A, MTHFR C677T) were investigated. The prevalence of the thrombophilic markers was compared in 156 women with history of fetal loss in different trimester of pregnancy and 80 matched controls. At least one thrombophilic defect was found in 28.2\% of total study group women compared with 16.2\% in controls (p=0.06; OR-2.02) and in 50\% of women with RFL in third trimester (p=0.008; OR-5.15). Factor V Leiden was more common in the group of women with fetal loss in third trimester (37.5\%) compared to the controls (6.2\%) (p=0.002; OR-9.0). Presence of FVL was associated with a significant increased risk for RFL in second and third trimester (OR-6.25; P<0.001) and significant protection for RFL in first trimester (OR-0.16; P<0.001). Mutation prothrombin G20210A or MTHFR C677T was more common in group of women with fetal loss in first trimester compared to the controls (28.3\% vs. 11.2\% respectively; p=0.009; OR-3.11). The presence of either of these mutations was associated with no significant increased risk for RFL in first trimester (OR-2.5). Genetic thrombophilic defects are common in women with RFL and are associated with late fetal loss. This association is manifest by FVL rather than total number of defects involved.
