Post vasectomy semen analysis
12 weeks AND 20 ejaculations after your vasectomy:

The semen sample must be produced after a 2-day period of no ejaculation.
Use the container provided to you. Do not use condoms or plastic bags.

Take your semen sample and the accompanying order form to a LabCorp location within 2 hours of collection. No appointment is necessary—just drop off the sample during business hours.
To find a LabCorp location near you, visit LabCorp.com, enter your zip code, and select "routine lab work" for location and hours.

Please note that you may receive a separate bill from LabCorp for their services, as this is not covered under the procedure.

You may also take the sample and order form to a different lab of your choice. Be sure to call ahead to confirm their specific requirements and instructions.

Once we receive the lab results, we will contact you with further information.

Until the semen sample shows absent sperm, you are still considered fertile.
If sperm are detected, continue using other forms of birth control and submit another sample in 4 weeks for re-evaluation.
