Home Testing May Not Improve Postvasectomy Semen Analysis Compliance

Vasectomy is the most effective form of permanent male contraception. Although vasectomy techniques and outcomes have steadily improved, postvasectomy semen analysis compliance remains a significant challenge. The aim of this study was to assess if home testing improved postvasectomy semen analysis compliance.

Data were collected prospectively but retrospectively reviewed between 2007 and 2019 from a single surgeon's high volume practice. Subjects were divided into 2 groups based on postvasectomy semen analysis method (home vs office) and further subdivided by compliance status. Patients were considered compliant if they provided at least 1 semen sample postvasectomy. Statistical analysis was completed to determine factors predictive of compliance.

A total of 364 patients were included. Median age for the home group vs the office group was similar (42 years [IQR 39-46] vs 41 years [IQR 38-46]). Median number of children for both groups was 2 (IQR 2-3). In all, 109 men (30.0%) opted for at-home testing. No significant difference in compliance was found (59.6% of home test vs 58.8% of laboratory patients, p=0.89). No statistically significant difference in patient demographics (age, partner age, number of children, smoking and alcohol) was observed, and there were no demographic factors predicting compliance with regression modeling.

At-home semen analysis kits did not significantly improve compliance. Clinicians should be aware that this may be a reasonable alternative for those who are unable to obtain a postvasectomy semen analysis in-office. Contact of the female partner instead may improve postvasectomy semen analysis compliance as the female partner has a stake in ensuring postvasectomy semen analysis azoospermia.
