The Analysis of Sialylation, N-Glycan Branching, and Expression of O-Glycans in Seminal Plasma of Infertile Men

Figure 1

The relative reactivity of seminal glycoproteins with lectins. The results are expressed in absorbance units (AU) as median values of relative reactivities with lectins. Seminal glycoproteins’ lectin reactivities were estimated by direct lectin-ELISA and expressed in absorbance units (AU). Seminal groups: NF: normozoospermic fertile, N: normozoospermic infertile, A: asthenozoospermic, O: oligozoospermic, OA: oligoasthenozoospermic. MAA: Maackia amurensis agglutinin, SNA: Sambucus nigra agglutinin, MPL: Maclura pomifera lectin, VVL: Vicia villosa lectin, and PHA-L: Phaseolus vulgaris leucoagglutinin. For lectin specificity see Section 2. Significant differences versus ^*normozoospermic fertile, ^**normozoospermic infertile, and ^***asthenozoospermic groups. Statistical significance of the differences was accepted for a value of less than 0.05.
