Earlier testing after vasectomy, based on the absence of motile sperm
1Cronulla Private Medical Clinic, Cronulla, New South Wales, Australia.
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.
Design:
A review of 2,260 seminal assay results from 3,178 consecutive vasectomies performed during a 17-year period.
Setting:
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.
