不育夫妇支原体感染及相关因素分析   总被引:2,自引:0,他引:2  
用间接血凝法对268例(134对)不育夫妇(其中不孕夫妇102对,有自然流产史的夫妇32对)作解脲支原体(UU)和人型支原体(Mh)的感染率血清学调查,同时检查了165例正常人血清以资对照。结果表明,268例不育夫妇支原体抗体UU阳性率为16.8%。Mh阳性率为12.3%,总阳性率为26.5%。正常对照组支原体抗体总阳性率为9.1%,二者相比差异非常显著,不育夫妇的支原体抗体滴度显著高于对照组。对不育男性作精液分析,表明支原体抗体阳性病人中45%的人精子活力(率)异常,15.0%的人精子形态异常;43例有生殖系炎症的妇女支原体抗体阳性率为48.8%,91例无生殖系炎症的妇女支原体抗体阳性率为22.0%,二者相比差异有显著意义。这些结果提示在不育人群中有相当一部分人存在着生殖道的支原体感染并成为不育病因之一,尤其当患者有精子活力(率)、形态异常或有生殖系炎症时,应把支原体感染检查作为一项重要的病因诊断参考依据。  相似文献

A reverse (antibody capture) enzyme-linked immunosorbent assay (ELISA) for detection of antisperm antibodies has been developed. The assay enables detection of immunoglobulin (Ig) M, IgG, IgA, or IgM, IgG, and IgA--antisperm antibodies in serum, cervical mucus, and seminal plasma samples. The reverse ELISA is more specific and sensitive than conventional ELISA in detecting human antisperm antibodies of different isotypes. Using this assay, statistically significant differences in levels of antibodies between infertile and fertile individuals were demonstrated in sera and in genital tract secretions. Studies with 143 infertile couples revealed that the presence of antibodies in sera was not necessarily reflected in individual's genital tract secretion and vice versa. These data emphasize the importance of detecting antisperm antibodies in sera as well as in genital tract secretions for correct evaluation of sperm immunity.  相似文献

An antisperm antibody enzyme-linked immunosorbent assay (ELISA) that uses whole unfixed sperm and detects immunoglobulin G (IgG) and IgA antibodies in serum was developed. Donor sperm were washed and plated on poly-L-lysine-treated microtiter plates. The patient's sera were diluted to concentrations of 1:4 to 1:256 and incubated with sperm. Positive and negative sera had been previously tested for IgG antisperm antibody activity with a radiolabeled antiglobulin assay. Samples were considered positive when the mean absorbance of triplicate wells was greater than 2 SD above the pooled negative mean. Intra-assay variation was 7.9 and 9.6% for pooled negative and positive controls, respectively. Identical titers of control positive serum were consistently detected. A correlation of 0.83 was observed between ELISA IgG serum titers and radiolabeled antiglobulin results (N = 12). All negative samples tested negative in both assays (N = 21). Some serum samples showed IgA antisperm antibodies. Determination and titration of class-specific antibodies in serum should facilitate initial screening and follow-up of patients at risk for antisperm antibodies.  相似文献

Immunobead Test, Indirect Immunofluorescence and ELISA, have been used to research antisperm antibodies in serum of 105 fertile male patients and in serum of 109 infertile male patients. Antisperm antibodies were present among 12.8% of infertile patients and 0.9% of infertile patients. The immunological factor is certainly an important factor in the aetiology of male hypofertility.  相似文献

Sperm reside within the female reproductive tract before the occurrence of fertilization. During this time they undergo surface modifications associated with changes in their functional state. To study their antigenic expression, capacitated and acrosome-reacted sperm were incubated with sera that had previously been tested for antisperm antibodies against fresh washed sperm, as detected by indirect immunobead binding. Forty-eight percent of previously positive and 20% of previously negative sera reacted differently with sperm after an extended time (18 hours) of incubation in serum or after sperm capacitation. These results suggest that current techniques of antisperm antibodies detection be modified to include testing sera after prolonged incubation times with both capacitated as well as fresh sperm.  相似文献

Two different ways of testing for antisperm antibodies were compared: the mixed antiglobulin reaction (MAR) test for demonstration of antibodies of the IgG and IgA classes bound in vivo to the sperm membrane antigens and the gelatin agglutination test for detection of nonbound antisperm antibodies in serum and seminal plasma. Samples from 537 men from infertile couples were investigated. Antibodies bound to the sperm membrane were detected in 49 men (9.1%), IgG in 44 (8.2%), and IgA in 38 cases (7.1%). Sperm agglutinins were recorded in seminal plasma from 30 men (5.6%) and in serum (titer greater than or equal to 16) from 43 men (8.0%). The investigation revealed a very close correlation between the results of MAR testing and the occurrence of sperm agglutinins in serum and seminal plasma. However, if one focuses on antisperm antibodies of the IgA class, which seem to play the major role in male immune infertility, the MAR test offered the advantage that a minor group of patients with pure IgG responses could be distinguished, and rare cases with mainly or exclusively locally produced IgA antibodies could be detected.  相似文献

The incidence and significance of antisperm antibodies in different groups of men were evaluated by a modified enzyme-linked immunosorbent assay. In serum, 4.0% of dermatologic patients (n = 223), 9.6% of andrologic patients (n = 178), and 28.6% of homosexual men (n = 42) were positive for IgG and/or IgM antibodies. In seminal fluids, 7.3% of the andrologic patients had IgA (and IgG) antibodies to spermatozoa. Only 1 of 29 positive men had antibodies both in serum and in seminal fluid. No correlation between antisperm antibodies and IgG/IgM concentrations was found in serum, whereas in seminal plasma men with antisperm antibodies showed higher IgG/IgA concentrations than men without (IgA, 3.2 versus 1.7 mg/dl; IgG, 9.8 versus 6.3 mg/dl). It is concluded that there is a high incidence of antisperm antibodies among homosexual men, probably because of contact of spermatozoa with the immune system by passive anal intercourse. There is little correlation between antisperm antibodies in serum and seminal plasma of infertile men because of a lack of relevant antibody transfer from the serum and the formation of local antibodies in seminal plasma. Antisperm antibodies in seminal fluid are associated with elevated local IgG and IgA concentrations.  相似文献

本文用ELISA法研究了174名男性不育患者及43名输精管粘堵术后精浆中的抗精子抗体及其种类。结果表明,精浆中抗精子抗体的检出率,在男性不育患者中为24.1%,输精管粘堵术后者为48.8%。在这些患者的精浆中可检出IgA、IgG和IgM型抗精子抗体,其中主要是IgA。同组人群血清和精浆中的抗精子抗体缺乏相关性。精浆中抗精子抗体的存在与精子活动率的下降有一定的关系。应用PEG法测定精浆中免疫复合物,在66例精子抗体阳性的患者中,阳性率为56.1%,表明局部抗精子的自身免疫反应,在一定条件下可导致免疫复合物的形成。  相似文献
