THE AIM: To monitor the basic andrologic and immunologic sperm factors and the levels of inhibin B in serum and in seminal plasma in men from the couples with infertility disorders. SETTING: Department of Gynecology and Obstetrics, Medical School, Charles University and University Hospital, Plzen, Institute of Molecular Genetics, AV CR, Prague, Institute of Clinical Immunology and Allergology, LF UK a FN, Plzen. METHODS: We used conventional methods for estimation of sperm quality according to WHO and we detected the intra-acrosomal proteins by monoclonal antibodies (Hs8 and Hs14, immunofluorescent method), spermantibodies by direct mixed antiimunoglobulin reaction (MAR) test, and we examined inhibin B in serum (< or =400 pg/ml= A) and in seminal plasma (< or = 600 pg/ml= N) by ELISA in 355 men aged 21-52 years (ø 34 years) with normal levels of FSH, LH and testosterone. The control group was created by 56 health sperm donors. RESULTS: We found 65% normospermatics in the group of 355 patients, 34.9% men with various kind of pathologies. Predominance of spermagglutinating antibodies was found in 15.77% in IgG, in 19.44% in IgA, in 8.44% in IgA and IgG together. Normal intraacrosomal proteins were reached in 74.65% for Hs8, in 20.85% pathologic, in 86.2% normal findings for Hs14, in 4.23% pathologic. The immunological results in control group were completaly negative. Pathological levels of inhibin B in seminal plasma was found in 37.2% (152 men), in 25% in serum, and in 5.6% in serum and in seminal plasma together. In 54.7% of patients we found physiological levels of inhibin B in both biological fluids. We also compared physiological 109/152 (71.71%), and pathological spermiogrammes 43/152 (28.29%) with abnormal levels of inhibin B in seminal plasma, with intraacrosomal proteins to levels of inhibin B in serum. Our detailed study shows high interidividual results, which must be studied in complex with diagnosis of decreased fertility in man. CONCLUSION: Andrologic and immunologic analysis in the group of 355 men showed normal parameters of spermiogrammes in 231 patients (65%), in the rest of men the immunologic profil was in various parts pathologic. Only 105 men have got excellent spermiogrammes. Inhibin B as hormon regulates in back the secretion of FSH, and serves as good indicator in male reproductive failures.
