    Abstract:
    OBJECTIVE: To evaluate the presence and activity of local sperm antibodies and electrophoretic analysis of ovulatory cervical mucus (OCM) to prove the correlation of results of Kremer mucus sperm capillary penetration test and i-MAR (mixed antiimmunoglobulin reaction) test with SDS-PAGE. DESIGN: Retrospective study. SETTING: Department of Obstetrics and Gynecology, Medical Faculty of Charles University, Pilsen. METHODS: 94 patients aged 22-40 (average age 32.3 years) were chosen for our study. Ovulatory cervical mucus was taken from uterine cervical canal in Consultation for Reproductive Immunology. Kremer test and indirect mixed antiglobulin reaction test for IgG, IgA, IgM and IgE were used for detection of sperm antibodies. For the SDS-PAGE analysis, OCM was incubated with sodium dodecyl sulfate. We studied separated protein fractions from OCM. RESULTS: Sperm-capillary ovulatory mucus penetration test (Kremer) was 0-10 cm/hour in our group (average value in patiens without sperm antibodies was 2.43 cm/hour, with sperm agglutinating antibodies 1.4 cm/hour), significant levels (> 45%) of spermagglutinating antibodies were detected in IgA in 6 patients (6.38%), IgG in 5 (5.32%) patients, sperm-cytotoxic levels (IgA and/or IgG) in 5 patients (5.32%); levels of IgE less than 30% in 3 patients (3.19%). Individual immunological factors gained by SDS-PAGE showed the spectrum of various molecular weights with range of 14.4- 350 kDa. The presence of IgG and/or IgA was in 53 cases (56.38%), with 13 ASA positivities (24.53% correlation with i-MAR test) and no ASA activity in 40 cases (75.47%); 6 ASA positive patiens (31.58%) were not detected by SDS-PAGE. CONCLUSIONS: Analysis of 94 OCM by SDS-PAGE showed several significant correlates, but their specifications will be based on further immunoblot research.
