Vasectomy is an operation that cuts the sperm transporting tubes called the vas deferens. This prevents sperm produced in the testes from entering into the semen. The goal of a vasectomy is to make a man sterile. This means that he will be unable to father children naturally. It is a very effective, safe and a permanent form of contraception.

Post-Vasectomy Testing to Confirm Sterility

The Post-vasectomy testing (Semen Analysis) is used to determine successful vasectomy. This test measures presence, motility and volume of sperm.

Single post-vasectomy sperm count test is performed at 3 months after vasectomy (after at least 20-25 ejaculations). If this test comes back negative (showing azoospermia), no further testing is needed. If the sample is positive at three months, then periodic monthly testing can continue until azoospermia is reached.
