Antisperm Antibody Test
How It Feels
Blood test
The blood sample is taken from a vein in your arm. An elastic band is wrapped around your upper arm. It may feel tight. You may feel nothing at all from the needle, or you may feel a quick sting or pinch.
Semen sample
Collecting a semen sample does not cause any discomfort. If masturbation is against your religious beliefs, talk with your doctor.
Risks
Blood test
There is very little chance of a problem from having blood sample taken from a vein.
- You may get a small bruise at the site. You can lower the chance of bruising by keeping pressure on the site for several minutes.
- In rare cases, the vein may become swollen after the blood sample is taken. This problem is called phlebitis. A warm compress can be used several times a day to treat this.
- Ongoing bleeding can be a problem for people with bleeding disorders. Aspirin, warfarin (Coumadin), and other blood-thinning medicines can make bleeding more likely. If you have bleeding or clotting problems, or if you take blood-thinning medicine, tell your doctor before your blood sample is taken.
Semen sample
Usually there are no problems from collecting a semen sample.
Results
An antisperm antibody test looks for special proteins (antibodies) that fight against a man's sperm in blood, vaginal fluids, or semen. The higher the level of antibody-affected sperm found in the semen, the lower the chance of the sperm fertilizing an egg.
What Affects the Test
Collecting a semen sample within 48 hours of ejaculating or after not ejaculating for longer than 5 days may affect the results of this test.
What To Think About
- Experts disagree about the usefulness of the test because the result may not change the treatment. Most people who have infertility problems because of sperm antibodies choose assisted reproductive technology to become pregnant.
