Even after prolonged obstructive intervals of 15 to 20 years, vasectomy reversal offers better or comparable success rates to intracytoplasmic sperm injection.

Outcomes for Vasectomy Reversal Performed After Obstructive Intervals of at Least 10 Years.
Kolettis PN, Sabanegh ES, et al:
Urology 2002; 60 (November): 885-888Objective: To determine the outcomes for vasectomy reversal performed after at least 10 years of obstruction. Methods: 74 vasectomy reversal procedures were performed in 70 patients after obstructive intervals of 10 to 24 years (mean, 14.5 years). These patients were retrospectively reviewed for patency and pregnancy rates. Results: The overall pregnancy rate was 37%. Patency rates for an obstructive interval of 10 to 15 years, 16 to 19 years, and >=20 years were 74%, 87%, and 75%, respectively. Pregnancy rates for these same periods were 40%, 36%, and 27%, respectively. Assuming a live delivery rate per cycle of 25% for intracytoplasmic sperm injection (ICSI), the delivery rate for vasectomy reversal would not be exceeded until an obstructive interval of at least 20 years.
Conclusions: The authors believe that even after prolonged obstructed intervals, vasectomy reversal offers better or comparable success rates to ICSI. Depending on their success rates at various medical centers, a threshold obstructive interval probably exists at which ICSI surpasses vasectomy reversal.
Reviewer’s Comments: This is, in my opinion, a clinically worthwhile paper. It clearly shows the pregnancy and delivery rates in patients who have undergone vasectomy reversal surpass the historical success rates of ICSI even after prolonged obstructive intervals. In addition, vasectomy reversal avoids the complication associated with multiple births, which is commonly seen after ICSI and is cheaper. In summary, even in patients with prolonged obstructive intervals after vasectomy, vasectomy reversal is probably more effective, cheaper, and less complicated than is ICSI. (Reviewer-George S.
