eng Abstract:
Recent studies have shown that infertility affects an estimated 15% of all couples. Male infertility is the primary or contributing cause in 60% of these cases. Consequently, application of methods of assisted reproduction is increasing. These methods would benefit from extended evaluation of the sperm quality. For this purpose, we analyzed sperm proteins in men with normal spermiograms and with asthenozoospermia. Ejaculates of both groups were tested with a set of well-characterized monoclonal antibodies (MoAbs) to human sperm. No statistically significant differences were found between normospermics and asthenospermics in the expression of sperm surface proteins clusterin, evaluated by Hs-3 MoAb, and semenogelin, evaluated by Hs-9 MoAb. On the other hand, flow cytometry revealed quantitative differences between normozoospermic and asthenozoospermic men in GAPDHS (glyceraldehyde phosphate dehydrogenase human sperm-specific glycolytic enzyme), evaluated by Hs-8 MoAb, VCP (valosin-containing protein), detected with Hs-14 MoAb, and PRKAR2A (cAMP-dependent protein kinase type II – alpha regulatory subunit) detected by MoAb Hs-36. Asthenozoospermic men displayed significantly reduced expression of intra-acrosomal proteins with a likely decrease in sperm quality, and thus a negative impact on successful reproduction.
