Post vasectomy semen analysis

Instructions for patients who have had a vasectomy and have an appointment to bring their sample into the hospital

Why have I been asked to produce a sample?

You have been asked to produce a semen sample to confirm that your vasectomy worked. 

Your first test should take place no earlier than 16 weeks after your vasectomy. After a minimum of 20 ejaculations.

Before your appointment

You must abstain (not have sex or masturbate) for between 2 and 7 days before your appointment. If you fail to do this we may not accept your sample.

Check that you have all your relevant paperwork. This includes your Cellular Pathology request form from your doctor, and a declaration signed by you. The declaration is included in this instruction pack. Please complete the declaration before coming to your appointment. The declaration must be completed by you, the patient. Please make sure you produce your sample within 1 hour of your appointment time. Delays of over an hour between sample production and analysis can have a detrimental affect on the sample. If you think you cannot get to the laboratory within an hour, let us know when you book your appointment. We can talk you through your options.

We will not be able to see you if you arrive without a Cellular Pathology request form from your doctor.

My sample pot

Your sample pot is also included in this instruction pack. The pot has been weighed and tested to make sure it will not have any effect on your sample. Please do not use any other pot to collect your sample. If you do, this may affect your results and you may have to repeat the test. You must label your sample pot yourself. Write the following details onto the pot label:

How do I produce my sample?

If your sample appears to have leaked, we will not be able to process it. You will have to rebook and repeat the test.

Is there anything I should not do?

Please do not use any lubricants. Lubricants and saliva can kill sperm. If they are detected in your sample, we will not be able to process it. You will have to rebook and repeat the test.

Please produce your sample at home. Do not produce your sample on hospital grounds. This is illegal, as the hospital is a public space. If we suspect the sample has been produced in the hospital (for example, in the toilets) we will not process your sample. You will have to rebook and repeat the test.

Please do not forget to bring your Cellular Pathology request form from your doctor. If you do not bring this form we will not be able to process your sample. You will have to rebook and repeat the test.

Where do I take my sample?

Your appointment is at Pathology reception at the William Harvey Hospital in Ashford. This is on the ground floor.

Go to the main entrance and follow the corridor in front of you to All Wards. At the end turn right towards the stairs and lifts. Go down the stairs, and turn right and follow the corridor. Pathology is on that main corridor on the right.

What do I do when I get there?

At Pathology reception tell the receptionist that you have an appointment with Andrology. A member of the Andrology team will meet you, and check your paperwork and sample pot. They will take your sample directly to the laboratory for analysis. If you have any questions, staff are available to speak to you.

What if I’m late?

If you think you will be late, please ring us, we will do what we can to help. If you arrive more than 20 minutes late for your appointment and have not contacted us, we will not be able to process your sample. You will have to rebook and repeat the test.

If you cannot attend your appointment, please phone us on 01233 616145 or 01233 616821. This allows us to give your appointment to another patient.
