{Abstract}: In 2012 the American Urological Association published vasectomy guidelines to promote best practices, including when to obtain post-vasectomy semen analyses. In this study we assessed practice patterns of post-vasectomy semen analysis since this guideline publication.<BR>We retrospectively analyzed a database of men who underwent post-vasectomy semen analysis between 2013 and 2017. Vasectomies were performed by urologist and nonurologist providers in academic and community settings.<BR>A total of 4,827 men underwent post-vasectomy semen analysis with 22.3% undergoing 1 or more repeat analyses. On initial analysis 58.2% were azoospermic, 28.3% had less than 100,000/ml rare nonmotile sperm, 8.7% had greater than 100,000/ml nonmotile sperm and 4.8% had motile sperm. The rate of repeat post-vasectomy semen analysis decreased from 30.7% in 2013 to 18.6% in 2016. Overall 72% of repeat post-vasectomy semen analyses were performed for patients with azoospermia or rare nonmotile sperm on initial post-vasectomy semen analysis. Of the 421 men with greater than 100,000/ml nonmotile sperm, 61.3% did not obtain a repeat analysis. Among cases of repeat analysis after initially having greater than 100,000/ml nonmotile sperm, 67.5% were downgraded to rare nonmotile sperm or azoospermia, 32.5% had a persistent count greater than 100,000/ml nonmotile sperm and none developed motile sperm.<BR>The rate of repeat post-vasectomy semen analysis is decreasing, likely highlighting a decrease in unnecessary testing. However, there is ongoing discordance between vasectomy guidelines and practice patterns, with 72% of repeat post-vasectomy semen analyses obtained unnecessarily based on guideline recommendations. Interestingly, no men with greater than 100,000/ml nonmotile sperm went on to have motile sperm on repeat post-vasectomy semen analysis. Further provider education is warranted and subsequent studies may allow for guideline modification wherein all nonmotile sperm are characterized similarly.
