1.1. Introduction: Unilateral ovarian agenesis has unknown etiology. Torsion of ovarian vessels during fetal life or early childhood can result in necrosis and resorption.
1.2. Case report: A 42 years old woman with infertility had referred to our clinic. Ultrasonography, hysterosalpingography, and laparoscopy found: normal left ovary left hydrosalpinx, and, in the right adnexal region, a tumor attached to the uterus. The right Fallopian was hypoplastic. The surgeons couldn’t visualize the right ovary, so they did the biopsy of the tumor. Histopathology found no ovarian tissue in the biopsy material - it was a leiomyoma.
