Introduction and Aim: The antinuclear antibodies (ANA) are unwanted molecules which bind and destroy certain structures within the nucleus. Immunofluorescence is a powerful technique that utilizes fluorescent-labeled antibodies to detect specific target antigens. The aim of this study was to detect the anti-testicular antibody among infertile males in Baghdad city and determine the most common type of infertility.
Materials and Methods: The study involved 73 male (53 infertile and 20 non-infertile) volunteers, at Kamal Al-Samarrai Teaching Hospital in Baghdad, Iraq. Serum collected from the study subjects was tested for steroid-cell antibodies (STC-Ab), anti-nuclear antibody (ANA) and anti-testicular antibodies (ATCA) by Indirect Immunofluorescence assay (IIFA). Data obtained was subjected to statistical analysis using the SPSS program.
Results: In the current study 52.9% of infertile men tested positive for testicular antibodies compared to the control group. The highest rate of testicular cell antibodies was observed in the serum of infertile patients aged between 30-39 years and the lowest in patients aged 50-59 years. The marriage duration among those showing the highest percentage of antibodies against testicular cells was 1-10 years. Study for the association of male infertility type to those positive for ATCA showed almost all (85.7%) patients with necrozoospermia to be positive for ATCA. This was followed by males with azoospermia (50%) and oligospermia (46.9%). The patients were negative for Addison’s disease while a few (28.6%) were positive for lupus erythematosus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
