Sperm-agglutinating antibodies in serum were positive at a titre of 1:32 or greater in 3% of normospermic control males and in 27% of vasectomized men. No significant changes were observed in prevalence of the antibodies over the period following vasectomy. There were no significant differences in prevalence of antibodies in patients with and without postoperative sperm granulomas. Antibodies were positive in 35% of vasectomized men just prior to vasovasostomy and in 29% of patients 12 months after a successful (patent) reversal operation. There was no significant difference in prevalence of antibodies in patients with successful and unsuccessful vasovasostomies. Antibodies were positive in 20% of men who achieved pregnancies and in 43% of those with persisting infertility in the presence of a patent vasovasostomy. Sperm agglutinating antibodies were present in 5% of the patients with pathological epididymal obstruction. They were negative in patients with a patent epididymovasostomy and positive in 17% of those with an unsuccessful epididymovasostomy. The four patients who achieved a pregnancy after epididymovasostomy were antibody-negative. The prevalence of antibodies in the serum of patients with azoospermia due to surgical vasal obstruction was higher than that in patients with azoospermia due to pathological epididymal obstruction. The agglutination patterns produced by sperm antibodies in the total group of positive sera were tail-to-tail in 56%, head-to-head in 30% and mixed in 14%.","PeriodicalId":10478,"journal":{"name":"Clinical reproduction and fertility","volume":"5 6","pages":"347-57"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14629531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NCD was significantly higher in the presence of 2 mmol/l dithiothreitol (DTT) and after washing sperm from semen with 6 mmol/l ethylenediaminetetraacetic acid (EDTA). NCD was significantly less in insemination suspensions prepared by the swim-up technique than in the original semen. NCD with DTT was inversely correlated with sperm motility and motility index but there were no significant relationships between NCD and other semen analysis variables. There was no significant correlation between any NCD test and the proportion of oocytes fertilised in vitro. The only factors being significantly correlated with the fertilisation rate were proportion of sperm with normal morphology (Kendall correlation, tau = 0.36, P less than 0.001) and sperm concentration (tau = 0.14, P less than 0.05). Logistic regression analysis of fertilisation rates showed that only percentage normal sperm morphology was significant. It is concluded that NCD does not provide additional useful clinical information about sperm fertilising ability in vitro.","PeriodicalId":10478,"journal":{"name":"Clinical reproduction and fertility","volume":"5 4","pages":"191-201"},"PeriodicalIF":0.0,"publicationDate":"1987-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14572685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Comparison of latex and polyacrylamide beads for detecting sperm antibodies.","authors":"R A MacMillan, H W Baker","doi":"","DOIUrl":"","url":null,"abstract":"The immunobead test is excellent for the routine screening of semen for sperm antibodies but the polyacrylamide beads currently used are of variable diameter (3-10 micron) which tends to obscure details of regional binding. Thus the use of smaller latex beads of more uniform diameter has been investigated. Latex beads were coated with IgG by exposure to anti D serum for a mixed antiglobulin reaction (MAR). Rabbit antihuman IgG and IgA antibodies were covalently bound to carboxylated latex microspheres (CLM) by the carbodiimide reaction. Polyacrylamide immunobeads (IBT) with antihuman IgG or IgA antibodies covalently attached were obtained commercially. The IgG IBT and MAR were compared in 55 samples. The MAR was positive in 15 of the 31 IBT positive samples but the proportion of sperm with attached beads was lower. CLM and IBT were compared in 106 samples. Both tests were positive in 34 samples with virtually identical proportions of motile sperm with beads attached and the patterns of attachment were similar. These results show that CLM microspheres give equivalent results to IBT and that as they are smaller and have a more uniform size they provide advantage in ease of detection of positive reactions and in determination of the regional blinding pattern.","PeriodicalId":10478,"journal":{"name":"Clinical reproduction and fertility","volume":"5 4","pages":"203-9"},"PeriodicalIF":0.0,"publicationDate":"1987-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14572686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
