Frequency of homozygous mutations for p53 tumor suppressor factor codon Pro72, plasminogen activator inhibitor 1 (PAI-1) 4G/4G, and vascular endothelial growth factor (VEGF) −1154A/A among 70 women with a history of recurrent implantation failure (RIF) compared with 73 fertile control women.

3. Figure 2
Distribution frequency of number of polymorphisms among women experiencing recurrent implantation failure and fertile control women. More than one polymorphism was observed more frequently among women with a history of recurrent implantation failure (RIF) compared with control women (P=.026).
