Summary
Longer driving times to semen analysis drop-off sites significantly reduce postvasectomy semen analysis (PVSA) compliance. Exploring at-home or in-office sample collection could improve patient adherence to essential follow-up care.
Area of Science:
- Urology
- Public Health
Background:
- Low compliance rates with postvasectomy semen analysis (PVSA) are a documented issue in current literature.
- Identifying factors influencing PVSA noncompliance is crucial for improving reproductive health outcomes.
Purpose of the Study:
- To determine factors correlating with noncompliance in postvasectomy semen analysis (PVSA).
- To assess the impact of geographical accessibility on PVSA submission rates.
Main Methods:
- Retrospective chart review of patients undergoing vasectomy.
- Utilized ArcGIS to calculate driving times to the PVSA drop-off site.
- Employed Kruskal-Wallis, chi-square tests, and multivariable logistic regression to analyze compliance factors.
Main Results:
- 42.5% of eligible patients (219/515) had no recorded PVSA.
- Shorter driving times (median 30.6 vs 34.2 minutes) were associated with higher PVSA compliance.
- Each 30-minute increase in driving time reduced the odds of PVSA submission by 48% (OR 0.52).
Conclusions:
- Driving time to a semen analysis drop-off center is a significant barrier to PVSA compliance.
- Consideration of alternative collection methods, such as at-home or in-office semen analysis, is recommended to enhance patient adherence.
