Abstract
Background: The immune infertility caused by anti-sperm antibodies (ASAs) represented about 1020%- of infertility among the couples, the ASAs interfere with sperm parameters such as the sperm motility and sperm ability to penetrate cervical mucus, sperm-oocyte binding, and fertilization and embryo developments. Objectives: The present study designed to assess semen analysis, presence of ASAs and DNA fragmentation index as well as correlation within these parameters in normzoospermic Iraqi subjects Patients, Materials and Methods: A total number of Iraqi subjects (116) with range of age (2051-) years and their mean duration of infertility (4.70 ± 2.77). Seminal fluid for Macroscopic and Microscopic assessments done according to WHO 2010 criteria. The mixed agglutination reaction (MAR) test used to assess theirASAs in semen (direct method), seminal plasma and serum (indirect method); for the both IgG and IgA classes of antibodies and their distribution among different parts of spermatozoa as percentage. Results: The mean of IgG using direct method was (23.881.75±) and for indirect detection method the mean was (27.412.41±) with no significant difference (P<0.05) between the two methods. While the direct method for IgA detection mean (14.46 ±1.76) and the mean for indirect method of detection (6.860.39±) and there was significant difference (P>0.05) between the two methods. In addition to that, the distribution of IgG and IgA detected by direct method on sperm parts showed no significance difference except for the sperm tail; while the indirect method for IgA and IgG showed significant difference in distribution on sperm mid-piece. Conclusion: The correlation among sperm parameters and Immunoglobulin using direct and indirect methods showing variations in significance also in the correlation between the direct and indirect methods according to distributions on sperm surface
