N2 - INTRODUCTION: Both women with polycystic ovary syndrome (PCOS) and women with twin pregnancies have increased risk of adverse pregnancy outcome. The aim of this study was to investigate the impact of PCOS and maternal androgen levels on the outcome of dichorionic twin pregnancy.MATERIAL AND METHODS: A retrospective study of 360 women with dichorionic twin pregnancies: 72 women with PCOS from a fertility clinic (years 1997-2010) and 288 women without PCOS from a hospital cohort (years 2005-2007). The obstetrical outcome was extracted from Danish National registers and supplemented by patient file data. In all, 65% of the PCOS group had a registered prepregnancy androgen level and these were stratified into normoandrogenic and hyperandrogenic women. The groups were compared by multiple regression analysis adjusting for mode of conception and prepregnancy body mass index.RESULTS: We found no overall impact of PCOS on the pregnancy outcome; the risks of preeclampsia, gestational diabetes and preterm delivery were comparable within the groups. However, five deliveries in the PCOS group compared with two in the control group occurred before gestational week 28. No difference in the obstetrical outcome between hyperandrogenic and normoandrogenic women was found. The body mass index in the PCOS population was lower than in the non-PCOS, possibly reflecting a higher socioeconomic status and a healthier lifestyle, which may underestimate the impact of a PCOS diagnosis.CONCLUSION: Neither PCOS nor maternal androgen levels confer additional risks to the outcome of dichorionic twin pregnancies of normal weight women.
