Ectopic ovary confirmed by ovarian stimulation in a case of unicornuate uterus

Objective: To present a case of unicornuate uterus with ipsilateral ectopic ovary and renal agenesis. Design: Case report. Setting: Research hospital. Patient(s): A 26-year-old woman with a 5-year history of primary infertility was admitted to our clinic. A unicornuate uterus without contralateral horn, with ipsilateral ectopic ovary and renal agenesis, was diagnosed. Intervention(s): Diagnostic laparoscopy, ovarian stimulation. Main Outcome Measure(s): During laparoscopy, a unicornuate uterus without a contralateral horn, together with ectopic ovary, was observed. Result(s): We visualized the right ectopic ovary on ultrasound after ovarian stimulation. Conclusion(s): We present a rare clinical entity that exhibits a unicornuate uterus without a contralateral horn, with ipsilateral right ectopic ovary and renal agenesis together. We conclude that ovarian stimulation is a useful approach in the diagnosis of ectopic ovaries. (Fertil Steril (R) 2011; 96: e122-4. (C) 2011 by American Society for Reproductive Medicine.)
