It should be noted that in previous studies only some of these polymorphic loci of the FSHB promoter (rs11031002 and rs11031005) and strongly linked SNPs (rs74485684, rs11031010r, s10835638, rs1782507, rs555621) have had demonstrated associations with endometriosis [5,6,10,12,18]. This evidence concerns the gene FSHB and endometriosis.
