Background:
Uterine synechiae or Asherman's syndrome is a condition that can cause infertility. The present experimental study was designed to establish the rabbit as an animal model for human Asherman's syndrome using the endometrial curettage.
Methods:
In an experimental study, female adult rabbits (n=18) were randomly divided into intact and ovariectomized groups. One third of caudal part of both uteri was submitted to traumatic endometrial curettage. One group was simultaneously ovariectomized. The intact rabbits were artificially induced ovulation during 10 days after surgery. One third of cranial part of both uteri was selected as the control. Synechiae occurring, luminal area/total area (LA/TA), endometrial area/total area (EA/TA), myometrial and perimetrial area/total area (MPA/TA), endometrial area/uterine wall area (EA/UWA), and myometrial and perimetrial area/uterine wall area (MPA/UWA) ratios of both uteri in six subdivided groups (n=6) were analysed in curetted and intact control parts. On days 15, 30 and 45 following surgery by two-way ANOVA and LSD test (p<0.05).
Results:
Histopathologic findings showed significant epithelial damage together with significant inflammatory reaction in the intact curettage group. The LA/TA ratios of the intact curettage group on days 15 and 45 were more than the intact control group on day 15. The EA/TA ratio of the intact curettage group on day 30 was less than the intact control group on day 30.
Conclusion:
Uterine fibrosis was observed in intact curettage group, and this modified animal model showed a pathogenesis condition similar to intrauterine adhesions observed in human.
