Abstract: Objective To systematically evaluate the association between 17beta-hydroxysteroid dehydrogenase type 5 (HSD17B5) and type 6 (HSD17B6) single nucleotide polymorphisms (SNP) and the risk of polycystic ovary syndrome (PCOS).Methods A comprehensive electronic search about published reports on the association of HSD17B5 or HSD17B6 gene polymorphisms with PCOS in China and abroad,which was conducted in PubMed. The Cochrane Library, EMBASE (OVID), CNIK, CBM, WangFang Date and VIP database and the retrieval time was up to June 2017. Two reviewers independently screened the literature according to inclusion and exclusion criteria, extracted data and assessed the bias risk of the included studies. The pooled ORs were performed using the Revman 5.3 software.Results Eight case-control studies were included:5 were about HSD17B5 rs3763676 that including 899 cases and 751 controls and 4 were about HSD17B6 rs3763676 that including 1 065 cases and 942 controls. The results of genetic model meta analysis in 3 studies showed no significant association between HSD17B5 rs3763676 gene polymorphisms and risks of PCOS(G vs A:OR=1.21,95% CI:0.98-1.49,P=0.070;GG+AG vs AA:OR=1.26,95% CI:0.85-1.86,P=0.250;GG vs AG+AA:OR=1.35,95% CI:0.86-2.12,P=0.190;GG vs AA:OR=1.47,95% CI:0.91-2.38,P=0.110;AG vs AA:OR=1.19,95% CI:0.79-1.78,P=0.410). Approximately, no significant association between HSD17B6 rs3763676 gene polymorphisms and risks of PCOS (C vs T:OR=1.13,95% CI:0.96-1.32,P=0.140;CC+CT vs TT:OR=1.06,95% CI:0.88-1.27,P=0.570;CC vs CT+TT:OR=1.48,95% CI:0.95-2.29,P=0.080;CT vs TT:OR=0.99,95% CI:0.81-1.21,P=0.950) except for CC vs TT codominant model(CC vs TT:OR=1.46,95% CI:1.02-2.09,P=0.040), but the results should be interpreted with caution.Conclusion Both HSD17B5 rs3763676 and HSD17B6 rs898611 single nucleotide polymorphisms are no associated with the risks of PCOS, but the results should be interpreted with caution.
