How to interpret the results

A negative result indicates a sperm concentration is below 300,000 sperm per milliliter of semen. A negative result is the desired outcome when testing a man who has undergone a vasectomy. This is an extremely low level of sperm. The World Health Organization standard for sperm count fertility is above 20 million sperm per milliliter.

• Two consecutive negative tests over a three-month period are required before you are considered sterile. Continue to use contraception until two consecutive negative results are obtained.
• A third test should be done at six months following your vasectomy to detect possible recanalization. Additional testing for recanalization should be performed once a year in the second and third year following a vasectomy.

A positive result indicates a sperm concentration above 200,000 sperm per milliliter of semen. There are a number of factors that affect a man’s progression to sterility. If you receive a positive result you should continue to use contraception and test yourself after waiting four weeks. You should continue to use contraception until two negative test results are obtained. If you receive two positive test results contact your doctor immediately.

All test results should be reported to your doctor’s office using the enclosed response card.

How accurate are the results

In clinical testing a negative result meant the sperm count was below approximately 300,000 sperm per milliliter of semen 100% of the time.

In clinical testing a positive result meant the sperm count was above 200,000 sperm per milliliter of semen 99% of the time.

Although no medical test can ever be 100% accurate, SpermCheck Vasectomy has been FDA approved to be equivalent to a microscopic analysis performed by a physician or reference laboratory.
