Abstract
This is a case report of a nulliparous young woman who suffered from prolonged menstruation and infertility for 1 year. Magnetic resonance imaging and a transvaginal ultrasound examination revealed cervical endometriosis. Treatment with a gonadotropin-releasing hormone agonist stopped the abnormal bleeding and enabled investigators to conduct a hysterosalpingogram, which suggested bilateral hydrosalpinx. Subsequently, the patient underwent in vitro fertilization and had a live birth after frozen-thawed embryo transfer with gonadotropin-releasing hormone agonist pretreatment.
