Antisperm antibodies were assessed in the serum samples of 73 men unable to ejaculate naturally and on the sperm cells of 13 of these men. None of the serum samples were found to be positive by sperm agglutination or sperm immobilization methods and antibodies were detected by an immunobead assay on the sperm cells of one of the 13 men examined.
Male infertility has been found to be a major factor in a couple’s inability to conceive in 50% of childless marriages. There are many causes of male infertility including: deficient sperm production, blockage of ducts through which sperm are transported from the testicles, hormonal abnormalities, failure of sperm to mature properly and antisperm antibodies. Varicocele is felt to play a major r...
two hundred and forty patients, who had undergone vasectomy from 1977 to 1985 and subsequent vasovasostomy ,were studied for the presence of sperm-specific antibodies by using the kibrick's gelatin agglutination test. the number of successful pregnancies and the presence of agglutination were also considered in this survey. sixty-nine pregnancies occurred in total and agglutination was present ...
Introduction: Antifertility effects of naturally occuring antisperm antibody (ASA) in infertile couples and studies on experimental immunization of various animals with sperm antigens represent ASA as an immunocontraceptive target. The effects of different factors on sperm immunogenecity and ASA production have been studied and different results have been reported. In this study, whole sperm im...
زمینه و هدف مطالعات نشان دادهاند که آنتیبادی ضد اسپرم (asa) ( antisperm antibody) میتواند با باروری تداخل نماید . asa میتواند در سرم یا مایع منی مردان از طریق آزمایشات متعددی مشخصگردد. در این مطالعه درصد asa از کلاس igg در مردان زوجهای نا بارور شهر خرم آباد بهوسیله تست واکنش آگلوتیناسیون مختلط (mixed antiglobulin reaction mar) مستقیم تعیین گردید. بهعلاوه ریسک فاکتورهای تشکیل دهنده a...
Previous studies on antisperm cell-mediated immunity (CMI) have been confounded by the presence of immunogenic leukocytes in sperm antigen preparations. In this study we isolated pure populations of viable spermatozoa on discontinuous Percoll gradients, and utilized sonicated and cavitated extracts, as well as live motile spermatozoa, to measure cellular immunity to spermatozoa in vasectomized ...
Numerous techniques may be used for evaluation of the different reproductive disorders of the stallion. Approaches may vary from real-time ultrasonography and biopsy for evaluating testicular tumors to use of special assays for evaluating sperm or plasma for presence of antisperm antibodies. This communication addresses techniques used to evaluate five relatively uncommon, but perplexing, disor...
