Shapes of the uterine cavity are different in women with polycystic ovary syndrome

Abstract

Purpose: A cross-sectional study was conducted to evaluate differences in uterine morphology between women with or without polycystic ovary syndrome. Methods: The authors recruited 333 infertile reproductive-age women including 93 with polycystic ovary syndrome diagnosed using the criteria of the Japanese Society of Obstetrics Gynecology-2007. Shapes of uterine cavity were measured by transvaginal three-dimensional ultrasound. Results: The polycystic ovary syndrome group had a significantly deeper indentation (2.2 ± 0.4 mm vs. 0.0 ± 0.2 mm, p < 0.0001) and a significantly more acute indentation angle (162.9 ± 2.2 deg vs. 175.2 ± 1.3 deg, p < 0.0001) than the control group. Conclusion: The depth and the apical angle of fundal indentation of uterine cavity are different in women with polycystic ovary syndrome.
