the presence of anti-sperm antibodies (asa) in semen or serum may impair sperm function leading to immunological infertility. the aim of this study was to investigate the presence of asa on the surface of sperm and in circulating blood of infertile couples. in this cross sectional study, we studied 49 couples suffering from infertility for at least one year. serum asa (igg and iga classes) was ...

The test most commonly used to detect sperm antibodies is the mixed antiglobulin reaction (MAR), standardized by the World Health Organization. The indirect MAR test detects soluble sperm antibodies in seminal plasma by using healthy donor spermatozoa as antigen. In this study we systematically investigated the influence of donor spermatozoa and the source of sperm antibodies upon the results o...

Introduction: The precise mechanism for antisperm antibody (ASA) mediated fertility impairment is unclear. In the male reproductive tract, ASA may have an adverse impact on sperm maturation and function or overall semen quality. In this study, the percentage of ASA-IgA was determined by the direct Mixed Agglutination Reaction (MAR) test in men from infertile couples in Khorramabad city. Further...

Sperm DNA fragmentation has been associated with reduced fertilization rates, embryo quality, pregnancy rates and increased miscarriage rates. Various methods exist to test sperm DNA fragmentation such as the sperm chromatin structure assay (SCSA), the sperm chromatin dispersion (SCD) test, the terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labelling (TUNEL) a...

Antisperm antibodies are detected in 3% to 25% of cases men and women diagnosed with infertility. They can also be 1–10% healthy fertile men. The presence a high titer AST is one the factors male infertility, which «hidden», i. e. not cause symptoms deterioration overall spermogram. objective: analyze results sperm testing antisperm antibodies, were by MAR-test. Material methods. A retrospectiv...

background: anti-sperm antibody (asa) can decrease sperm motility and, therefore, it is a cause of male infertility. the aim of this study was to evaluate the effects of varicocelectomy on anti-sperm antibody in patients with varicocele. methods: this observational study was conducted on 90 patients with varicocele at sina and imam khomeini hospitals during 2006 to 2009. all varicocelectomy can...

Background: Although in vitro fertilization (IVF) has been found to bypass the inhibitory effect of high levels of antisperm antibodies on sperm motility, fertilization rates are reduced in approximately 40% of the attempts. In this study, we investigated the relationship between antisperm antibodies measured by the direct mixed agglutination reaction (MAR) and the fertilization rate in inferti...
