Post-vasectomy analysis


Lab Code : PV


Test Background
The complete absence of sperm from an ejaculate is the most relevant criterion used to determine the successful surgical operation of a vasectomy procedure.


Clinical Indications
Following a vasectomy.


Sample Required
A complete fresh ejaculate produced on site in one of the Andrology Department's production rooms.


Samples produced offsite will no be processed as of 1st June 2017


Turnaround Time
14 Days


Notes
Minimum detection limit
Minimum detection limit for this assay is 17080 sperm per ml. 

Guidelines published in 2016 in a collaborative report by the Association of Biomedical Andrologists, British Andrology Society & British Association of Urological Surgeons state that:
Post vasectomy semen analysis should take place a minimum of 12weeks after surgery and after a minimum of 20 ejaculations. Samples should also be assessed within 4 hours of production and if non-motile sperm are observed, further samples must be examined within 1 h of production. Assessment of a single sample is acceptable to confirm vasectomy success if all recommendations and laboratory methodology are met and no sperm are observed. Clearance can then be given.
