Earlier testing after vasectomy, based on the absence of motile sperm.
OBJECTIVE
To review the results of postvasectomy testing when clearance was based on the absence of motile sperm and to compare them with regimens based on complete azoospermia.


METHODS
A review of 2,260 seminal assay results from 3,178 consecutive vasectomies performed during a 17-year period.


METHODS
An outpatient vasectomy service in a private group practice in suburban Sydney.


RESULTS
Clearance was given sooner and with less testing than with other reported regimens, without loss of reliability.


CONCLUSIONS
Testing can be done 4 weeks after vasectomy, regardless of the number of postvasectomy ejaculations. If specimens are examined within 12 hours of collection, clearance may safely be given if motile sperm are absent. Repeat tests are essential if any motile sperm remain but are not needed if only nonmotile sperm are found.
