This study determined the prevalence of EH among women with infertility due to PCOS and assessed the predictive value of endometrial thickness (ET) measurement by trans-vaginal scan (TVS). Study Type & Population: This was a prospective study on infertile women with and without PCOS in which clinical data, hormonal profile, ET and endometrial biopsy (EB) for histopathological examination were collected. Methods: Thirty-seven women with PCOS and 23 women without PCOS presenting with infertility and/or abnormal uterine bleeding underwent TVS, hysteroscopy, laparoscopy and EB. Results: The overall prevalence of EH was 23.3 % while in PCOS group: 18.3 %. The mean ET (14.8 mm) was significantly higher in patients with EH (t = -2.74, P value = 0.009). The lower value of ET among women with EH was 10 mm. A cut-off point of 9.5 mm was set. An ET of >9.5 mm had 92.9% sensitivity and 51.85% specificity for the presence of EH. Women with ET ≥ 9.5 mm were 1.28 times more at risk of EH than women with ET 9.5 mm. Women with oligomenorrhea and irregular cycles were 5.5 and 13.7 times more at risk of EH compared to those with regular cycles, respectively. ET was positively correlated with insulin resistance (r = 0.439, P = 0.007). Conclusion: ET ≥ 9.5 mm predicts EH in infertile women with PCOS, with a high degree of sensitivity and a moderate degree of specificity. In PCOS patients with oligomenorrhea or irregular cycles, the risk of EH is higher than women with regular cycles.展开更多
