Antisperm Antibody Test

Clinical definition of the Antisperm Antibody test
An antisperm antibody test is done to find antibodies against a man's sperm in blood, vaginal fluids, or semen. They can be produced either in a man's or woman's body.

Why is the Antisperm Antibody test done?
This test is done to find the reason of infertility when the couple is unable to produce children or to analyze the health of the reproductive organs. It is done as a blood test in females and as a sperm test in males. The antibodies can damage or kill sperm causing infertility. This is called immuno-logical infertility. Anti sperm antibodies can be made in the body of the man in the following cases:

  • When the testicles are injured
  • After surgeries (such as a biopsy or vasectomy)
  • To check the success of a vasectomy ( sterilization procedure for males)
  • After a prostate gland infection
  • Testicular cancer

A woman may have an allergic reaction to her partner’s semen, thus producing antibodies against it and causing infertility.

What are the common signs/symptoms when the Antisperm Antibody test is done?
Antisperm Antibody test is done when the couple might have a fertility problem and the woman is unable to conceive.

Who should do the Antisperm Antibody test (Target population)?

  • Couples suspected to have an infertility problem
  • As a follow up to a surgery such as a biopsy or a vasectomy
