Abstract
Objective:
To evaluate uterine function by using cine magnetic resonance imaging to visualize the contractile movements of the uterus in patients with and without deep infiltrating endometriosis (with or without associated adenomyosis).
Materials and Methods:
This was a prospective case-control study. The study sample comprised 43 women: 18 in the case group and 25 in the control group. We performed cine magnetic resonance imaging in a 3.0 T scanner, focusing on the presence, direction, and frequency of uterine peristalsis.
Results:
The frequency of uterine peristalsis was higher in the case group than in the control group, in the periovulatory phase (3.83 vs. 2.44 peristaltic waves in two minutes) and luteal phase (1.20 vs. 0.91 peristaltic waves in two minutes). However, those differences were not statistically significant. There was a significant difference between the patients with adenomyosis and those without in terms of the frequency of peristalsis during the late follicular/periovulatory phase (0.8 vs. 3.18 peristaltic waves in two minutes; p < 0.05).
Conclusion:
The frequency of uterine peristalsis appears to be higher during the periovulatory and luteal phases in patients with deep infiltrating endometriosis, whereas it appears to be significantly lower during the late follicular/periovulatory phase in patients with adenomyosis. Both of those effects could have a negative impact on sperm transport and on the early stages of fertilization.
