Abstract :
Background: This study was aimed to assess the effect of endometrial movements on
pregnancy achievement in intrauterine insemination (IUI) cycles.
Materials and Methods: The population of this observational study was composed of
unexplained infertility couples undergoing first-time IUI with clomiphene citrate between
September 2010 and October 2011. Not only endometrial movements, but also thickness,
volume, pattern, and echogenic change of endometrium were analyzed prospectively in
prediction of pregnancy.
Results: The total number of 241 cycles of IUI with 49 intrauterine pregnancies
(20.3%) was analyzed. Pregnancy was not related to endometrial thickness and endometrial
volume, but significantly related to endometrial movements associated
with the number of contraction, strong movement, cervicofundal direction, and hyperechoic
change (p < 0.05). Pregnant group showed higher cervicofundal movement
rate (89.8 vs. 75.5%).
Conclusion: For IUI cycles stimulated by clomiphene citrate in unexplained infertility
women, endometrial movements on the day of IUI could be a predictor of pregnancy.
