Additionally, we performed two meta-analyses for MMP9rs3918242 polymorphism in endometriosis/adenomyosis and preeclampsia but found no association with either disorder.
We conclude that MMP-7-181A/G polymorphism has a potential to be a susceptibility factor for endometriosis and adenomyosis while MMP-9-1562C/T polymorphism may not provide a useful marker to predict susceptibility to endometriosis and adenomyosis, at least in women from North China.
