Use of transperineal fine needle aspiration of seminal vesicles to retrieve sperm in a man with obstructive azoospermia

OBJECTIVE: To report the successful and feasible use of transperineal fine needle aspiration of seminal vesicles (FNASV) for sperm retrieval in obstructive azoospermia. DESIGN: Case report. SETTING: Outpatient care in institutional clinic. PATIENT(S): A 31-year-old man with obstructive azoospermia due to a middle prostatic müllerian cyst. INTERVENTION(S): Transperineal FNASV using a coaxial 17-gauge TruGuide needle. MAIN OUTCOME MEASURE(S): Feasibility of sperm retrieval suitable for future in vitro fertilization. RESULT(S): Transperineal FNASV made it possible to aspirate 11 mL of fluid with a sperm count of 100 million/mL and 15% motility. This sample was cryopreserved for in vitro fertilization using intracytoplasmic sperm injection. CONCLUSION(S): Transperineal FNASV using a coaxial needle may be a further method for sperm retrieval to add to the repertoire of assisted reproduction technologies.
