Comparative Effects of Ovariectomy and Flutamid on Body-Uterus Weight and Uterine Histology in the Ovariectomized Rat Model+ -

Objective: To determine the effect of flutamide on uterine histology and to ascertain whether flutamide regulates body weight gain in the ovariectomized rat model. Materials and Methods: We used 36 sexually mature female Wistar-Albino rats in this study. The study was performed in the Department of Medical Science Application and Research Centre of Dicle University, Diyarbakir. We divided the model rats into 3 groups: group 1- control group, group 2- sham-operated group and group 3- bilaterally ovariectomized group. In addition, we gave flutamide to group 3. Results: We found that the body weight was higher in the ovariectomized rats than the control rats, unlike the decreased uterine net weight. Furthermore, body weight decreased slightly after flutamide therapy, however uterine net weight increased. After flutamide applications, the length of uterinal epithelium, the number of uterinal glands, infiltration of the stromal cells increased and the lumen of uterinal glands were dilateded. Conclusion: As a result, an improvement was observed after flutamide applications while bilateral ovariectomy was determined to cause atrophy in the uterine epithelium of rat. Our study may be source for further research examining the relationship between the androgen receptor antagonist flutamide and reproductive function in female rats.
