title: [Operative sperm retrieval - the urological aspects].
abstract: Nowadays operative sperm retrieval in connection with assisted reproduction is a well established procedure in urological-gynecological co-working-groups. MESA (microsurgical epididymal sperm aspiration) and TESE (testicular sperm extraction) are the fundamental procedures in case of non-reconstructable obstructive azoospermia or testicular azoospermia. Percutaneous techniques as PESA (percutaneous epididymal sperm aspiration) or PTESE (percutaneous testicular sperm extraction), as they are often favorised in the anglo-american countries and the countries of Northern Europe have to be discussed to their efficacy (number of retrieved spermatozoa) and the possible testicular injury due to the blind or ultrasound-guided puncture.
