Insights
Including rare nonmotile sperm parameters significantly increases postvasectomy clearance rates. However, patient compliance with postvasectomy semen analysis testing remains a challenge for effective contraception.
Area of Science:
- Urology
- Reproductive Health
- Public Health
Background:
- Postvasectomy semen analysis (PVSA) is crucial for confirming successful vasectomy.
- Current clearance parameters may exclude men with nonmotile sperm, potentially leading to unnecessary further testing.
Purpose of the Study:
- To evaluate the American Urological Association's suggested postvasectomy clearance parameters (<100,000 nonmotile sperm/mL).
- To determine the cost savings associated with adhering to these parameters and avoiding additional testing.
Main Methods:
- Retrospective review of vasectomy patients from December 2009 to August 2012.
- Collection of patient demographics and postvasectomy semen analysis (PVSA) results.
Main Results:
- Of 111 patients with initial PVSA, 36.0% had sperm present.
- 38 of 39 patients (97.4%) with nonmotile sperm met clearance criteria.
- Incorporating nonmotile sperm parameters increased clearance from 64.0% to 98.2%, saving $2356 in repeat testing.
Conclusions:
- Including nonmotile sperm parameters enhances postvasectomy contraceptive clearance.
- Poor compliance with postvasectomy semen testing hinders effective contraception confirmation.
Objective:
To determine the applicability of postvasectomy special clearance parameters (<100,000 nonmotile sperm/mL on semen analysis) suggested by the American Urological Association and to define the associated cost savings with avoidance of further testing.
Materials And Methods:
We retrospectively reviewed the cohort of men undergoing vasectomy from December 2009 to August 2012 at a single institution. Patient demographics and postvasectomy semen analysis (PVSA) results were collected for clearance parameter comparisons.
Results:
During the study period, 230 patients underwent vasectomy with a mean ± SD age of 36.4 ± 6.5 years. Among the cohort, 83.5% were married and 95.2% had one or more children. The initial PVSA was completed by 111 (48.3%) patients at a mean of 17.8 weeks (range 4-45) following vasectomy. Sperm was identified on initial PVSA in 40 patients (36.0%); 1 patient was found to have motile sperm. Of 39 patients, 38 (97.4%) with nonmotile sperm on PVSA could be cleared to cease other contraceptives based on the most recent clearance guidelines. For those completing an initial PVSA, postvasectomy clearance increased from 64.0% to 98.2% representing a potential cost savings of $2356 in repeat semen testing.
Conclusion:
Postvasectomy contraceptive clearance can be greatly increased when rare nonmotile sperm parameters are included although postvasectomy semen testing compliance remains poor.
