Confirm Vasectomy Effectiveness
It is important to start ejaculating from Day 7 post procedure.
You need to do at least 25 ejaculations over a 20-week period (5 months) post procedure to clear the remaining sperm in the system.
On the day of your procedure we gave you instructions on how to provide a sample, and an addressed sample pack. You will receive a reminder email to produce your sample at 20 weeks after your procedure, but on the day of your procedure please take note of this date in your diary also.
Please follow the instructions accompanying the pack and return the sample to the lab by post.
They will process the sample and return the results to us after 3 weeks. We will email or call you with the results.
If the sample is clear of sperm, then all other forms of contraception can be discontinued at this point.
In approximately 5-10% of cases there will be residual sperm seen in the sample and further samples may be required.
Please do not give up alternative forms of contraception until your sample has been confirmed clear of sperm and you have received this confirmation from the lab.
