title: Refertilization surgery. A surgeon's experience of over 27 years with nearly 2000 patients.
abstract: OBJECTIVE
  The aim of this paper was to present the experiences of microsurgical refertilization in a single-centre study during a period of 27 years.
  
  
  METHODS
  Nearly 2000 patients were operated by a single surgeon (JUS). A total of 1708 patients were evaluated in a data base, 1164 were available for a follow-up. Both vasovasostomy (VV) and epididymovasostomy (EV) were carried out in a three-layer technique. Vasectomy reversal (VR) end-to-end VV was performed only if spermatozoa had been demonstrated at the epididymal stump of the vas. In all other cases of VR, EV was done in a preocclusive region of the epididymal tubule. In the cases of postinfectious obstruction (PIO) of seminal pathways, an EV was always carried out.
  
  
  RESULTS
  The outpatient procedure of refertilization was associated with a very low complication rate, which underlines its minimal-invasive character. The follow-up rate was 68%, the overall patency rate was 88% for VR and 67% for PIO and the pregnancy rate was 59% for VR and 38% for PIO. Secondary azoospermia was observed in 1% of the patients.
  
  
  CONCLUSIONS
  In relation to the intervals of obstruction, the patency and pregnancy rates were higher after short-term obstruction than after long-term obstruction. There is a significant discrepancy between patency and pregnancy rates that is likely to be caused by a relevant number of patients with postoperative asthenozoospermia.
