Spermagglutinating antibodies: a comparison of three different techniques

Area of Science:

• Reproductive Immunology
• Infertility Research

Background:

• Circulating spermagglutinating antibodies are implicated in infertility.
• Accurate detection methods are crucial for diagnosis.

Purpose of the Study:

• To investigate the prevalence of spermagglutinating antibodies in infertile patients.
• To evaluate the efficacy of different serological tests for detecting these antibodies.

Main Methods:

• Spermagglutinating antibodies were tested in 136 infertile patients.
• Positive cases were further assessed using Friberg, Kibrick, and Franklin-Dukes tests.

Main Results:

• Antibodies were detected in 40% of unexplained infertility cases (6/15).
• In patients with known infertility causes, 15% (15/101) showed positive antibodies.
• The Friberg test showed 81% positivity, Kibrick 67%, and Franklin-Dukes 19% in antibody-positive cases.

Conclusions:

• Spermagglutinating antibodies are significantly present in unexplained infertility.
• The Friberg and Kibrick tests are highly effective in detecting these antibodies.
