ExSeed’s Home Test has not been certified to assess whether there are no sperm cells present or the effectiveness of various methods of contraception, both temporary and permanent (like vasectomy). Therefore, we would not be able to provide a conclusive answer based on our home test. That being said, a relatively large number of people have used ExSeed to give an indication on whether there are live sperm cells present post-operation or in other circumstances. In the app, there is a button you can click on to indicate you’ve had a vasectomy, which will make the Medical Team do an extra careful manual assessment (visual inspection) of the test as well.
