Transabdominal-transperitoneal ultrasound-guided oocyte retrieval in a patient with müllerian agenesis

Objective: To describe the approach of transabdominal-transperitoneal ultrasound-guided oocyte retrieval undertaken in a patient with müllerian agenesis and ovarian malposition who underwent a successful gestational carrier treatment cycle. Design: Case report. Setting: A tertiary-referral reproductive medicine unit. Patient(s): A 26-year-old patient with müllerian agenesis. Her 44-year-old mother served as the gestational carrier. Intervention(s): Controlled ovarian hyperstimulation, transabdominal-transperitoneal ultrasound-guided oocyte retrieval, embryo transfer. Main Outcome Measure(s): Oocyte recovery rate, fertilization rate, pregnancy test. Result(s): Six oocytes were retrieved using a percutaneous transperitoneal needle puncture under ultrasound guidance. Two cleavage-stage embryos were transferred to the gestational carrier, resulting in a twin pregnancy. Conclusion(s): For various reasons, patients with müllerian agenesis may not be candidates for standard transvaginal ultrasound-guided oocyte retrieval. Although laparoscopic oocyte retrieval has been frequently used in this setting, the approach of transbdominal-transperitoneal ultrasound-guided oocyte retrieval may offer further advantages in select cases.
