Before you start
Wash and dry your hands and genitals before collecting your specimen to reduce
contamination. Please ensure all soap residue is removed.
You will need
•
•
•
2 specimen containers
2 specimen request forms
2 specimen transport bags
When to collect your samples
You must not have intercourse (or masturbate) for at least 3 days before the test. However you
must also not abstain from intercourse (or masturbation) for more than 6 days prior to the test.
You must have had at least 24 ejaculations since your vasectomy for the test to be valid. You
must collect your sample in the morning. Samples need to be taken to the laboratory as
soon after collection as possible for examination the same day.
•
•
Collect your first sample at least 16 weeks after your operation
Collect your second sample at least 2 weeks after your first sample
Some doctors advise a different time schedule for testing semen samples after vasectomy.
However, the Microbiology Laboratory at Stockport NHS Foundation Trust still feels it is safer to
test at least 2 semen samples and get negative results in at least 2 samples before giving the
‘all clear’. If sperm are seen in a post-vasectomy semen sample you will be asked for further
samples to be tested until negative results are achieved.
How to collect your sample
Obtain the specimen by masturbation and pass it directly, without loss, into the container
provided. Don’t use a condom as this will affect the results.
Secure the top of the container tightly.
Please check the specimen container label has

Finally
Place the form in the pouch of the specimen transport bag. The specimen and request form
should be delivered to the Department of Laboratory Medicine at Stepping Hill Hospital

For accurate results the sample needs to be examined on the day of collection. The
Microbiology Laboratory preferably accepts semen samples for post-vasectomy sperm count on
weekdays (excluding Bank Holidays) from 8.30am to 11.30am. NB: If you plan taking your
sample to your GP surgery for transport to us you should check when specimens are
transported to the laboratory so that the sample can reach us and be examined on the same
day as collection.
* Your Doctor will have a written report within 7 days of your test.
