RESUMO
Background: The first immunological correlation with male infertility was reported in 1954 by Wilson and Rumke with the identification of anti-sperm antibodies. The prevalence of anti-sperm antibodies in infertile men varies from 9%-36%, the main cause being the loss of the blood-testicular barrier and otherwise the association with chronic inflammation. It has been shown that immune infertility is found in 15% of patients with varicocele.Methods: A transversal comparative study was carried out with 360 infertile men who were tested for anti-sperm antibodies between January 2011 and July 2018. Two groups were integrated; Group 1, infertile men with positive anti-sperm antibodies >50%, group 2, infertile men with negative anti-sperm <50%. Seminogram parameters were evaluated according to the WHO 5th edition and associated risk factors with anti-sperm antibodies.Results: 360 infertile men were evaluated during the study, 42 were excluded because they did not meet the inclusion criteria, the prevalence of anti-sperm antibodies was 14.5%. Group 1; n=46 (14.5%) and group 2, n=272 (85.5%), the clinical characteristics and the hormonal profile were compared at study admission without significant difference. There was a significant decrease in progressive motility in group 1 (38.7±23.8) vs group 2 (50.1±18.9) p=0.03. Analyzing the risk factors, varicocele was found to be significant 23.7%, OR 2.14 (1.27-3.61) p=0.004 as well as retractable testicle 26.4%, OR 2.13 (1.23-3.70) p= 0.008.Conclusions: The affectation of motility was confirmed, which leads to the suspect varicocele and retractable testicle as risk factors.
RESUMO
Objective To explore the application value of detection of Mycoplasma,Chlamydia and anti-sperm antibodies for male infertility.Methods Culture method,immune chromatography,and enzyme linked immunosorbent assay were adopted for the detection of Mycoplasma,Chlamydia,and anti-sperm antibodies respectively in 102 cases of infertile males and 42 cases fertile males.And the routine semen analysis was proceed as well.All the subjects were divided into 4 groups according to the detection re-sults:simple Mycoplasma or/and Chlamydia positive group(71 cases),simple anti-sperm antibodies positive group(21 cases),My-coplasma and Chlamydia or/and anti-sperm antibodies positive group(8 cases),Mycoplasma,Chlamydia and anti-sperm antibodies negative group(44 cases).The main indexes of semen routine were compared among 4 groups.Results The positive rates of Myco-plasma,Chlamydia and anti-sperm antibodies in infertile males were significantly higher than those of fertile males (P <0.05).The sperm densities,activity rates,activity of simple Mycoplasma or/and Chlamydia positive group,simple anti-sperm antibodies posi-tive group,and Mycoplasma and Chlamydia or /and anti-sperm antibodies positive group were significantly lower than the nega-tive group,while the sperm malformation rates,liquefaction times,white blood cell counts of the three groups were significantly higher than the negative group(P <0.05 ).Conclusion Mycoplasma,Chlamydia infection and anti-sperm antibodies production have significant effect on the indexes of semen,which cause decline in semen quality and the occurrence of male infertility.
