Title: Predictors of live birth after vasectomy reversal in a specialist fertility centre
Authors: Davis, NF; Gnanappiragasam, S; Nolan, WJ; Thornhill, JA
Description: In a retrospective review of 106 consecutive vasectomy reversals (May 2002-April 2015) in our institution, patients were stratified according to post vasectomy obstructive interval (PVOI); less than 5 years, 5–10 years, 10-15 years and >15 years. Positive semen analysis and live birth rates were analysed. Logistic regression tested potential predictors for these outcomes. Overall patency rate (positive semen analysis) was 75% and live birth rate was 41%. Shorter PVOI was a significant predictor for positive semen analysis (p=0.028). Male smoking or male age at reversal had no significant correlation (p=0.99 and 0.95 respectively). For a live birth, PVOI and female age (threshold: 36 years) at reversal were significant predictors (p=0.007 and p=0.043 respectively). Outcomes compared favourably with international series yielding satisfactory pregnancy rates, particularly with a short obstructive interval and in females <36 years of age
