Abstract

INTRODUCTION: We used a home-based (HB) post-vasectomy semen analysis (PVSA) between 2014 and 2017, but we have since reverted to local lab-based (LB) testing. In this study, we compared PVSA compliance rates in HB and LB test settings and describe factors that may influence completion rates.

METHODS: We retrospectively identified patients who underwent vasectomy at our institution. Surgeons X and Y performed vasectomies from 2014–2017 using a HB immunochromatographic PVSA kit. From 2017–2020, surgeon X used a local LB PVSA. We collected data on PVSA completion status and patient demographics to perform two analyses. HB testing was examined by assessing all patients who had a vasectomy from 2014–2017. Another compared HB and LB testing by looking at surgeon X vasectomies from 2014–2017 and 2017–2020.

RESULTS: We identified 285 patients who underwent vasectomy from 2014–2017 and were assessed with HB testing. Compliance with PVSA was 35% with HB PVSA. Age at vasectomy, number of children, and surgeon influenced PVSA completion in the 2014–2017 cohort. Surgeon X PVSA completion was 29% for the HB (n=136) testing cohort and 46% for the LB (n=201) cohort (odds ratio 0.47, 95% confidence interval 0.29–0.74). Again, more children decreased PVSA completion.

CONCLUSIONS: Compliance with PVSA testing was inadequate in both test settings, although it was significantly higher in local LB setting. Based on these findings, the convenience of HB testing appears to decrease compliance with PVSA, although surgeon factors may be influential. These findings may help surgeons identify factors that improve PVSA compliance rates.
