Bagshaw et al identified factors favoring male fertility following vasectomy reversal. These can help identify a patient who will have a reasonable chance at conception. The authors are from St. Peter's Hospital in London.
Parameters:
(1) interval between vasectomy and reversal
(2) length of resected segment
(3) appearance at the cut proximal end of the distal vas prior to reanastomosis
(4) circulating antisperm antibodies
(5) sexual partner

where:
• A long time interval, a long segment, cheesy material and antisperm antibodies are unfavorable findings.
number of favorable findings =
= SUM(points for all 5 parameters)
Interpretation:
• minimum number of favorable factors: 0
• maximum number of favorable factors: 5
• The chances of conception by the sexual partner increases as the number of favorable factors increase.
